1, Eighteen species of aquatic Hyphomycetes are recorded from South Africa for the first time. All except two of these can be assigned to described species. The other two are new species of Articulospora and Anguillospora and are described in this thesis. Three unidentified spore types, an "Articulospora" type and "Anguillospora" type and a Y-shaped spore are also described. 2. Spore development in ten species is described. 3. A key to the fungi described in this thesis is given. 4. General notes on the ecology of these fungi and a table recording the fungi found in the Eastern Cape Province of South Africa, their distribution within the localities and the nature of the material on which they are growing are given. 5. The gross characteristics of plate cultures of six species, five growing on malt agar, Czapek agar, plain agar and maize agar and one on malt agar only are described. 6. Growth of four species in liquid culture using the Czapek-Dox medium is reported. 7. The results of an investigation into the effect of variations in temperature and medium on the growth of plate cultures of five species are analysed, discussed and conclusions are drawn. 8. Growth of certain isolates of four species on twigs is described.

A taxonomic study of Southern African hyphomycetesBoshoff, Sanette 10 October 2005 (has links)
From May 1994 until the end of August 1994, pieces of decomposing wood and twigs were collected from different locations in the Northern Cape Province, Gauteng, Mpumalanga and in the Western Cape. Fifty-nine taxa were recorded (one new genus, one new species and 43 new records from southern Africa). This study reviews the development of the taxonomy of the mitosporic fungi, in particular the Huyphomycetes, makes some comments on the structure-function relationships and functional diversity that occur and describes a large number of new Hyphomycete records for southern Africa. The classification of these micro-fungi has been controversial since inception. As the asexual phase of a sexually reproducing organism (the ascomycete or basidiomycete states), the taxonomy is covered by a dualistic nomenclature whidh is an exception of Principle IV (one organism: one name) of the International Code of Botanical Nomenclature (ICBN). Alth9ough the role of morphological features in the development of anamorph taxonomic theory has evolved as microscopic image technology has advanced, inadequately defined characters, obscure distinctions between morphologically similar species and a weak theoretical base undermine the usefulness of this system. Molecular systematic studies are yielding a wealth of new fungal taxonomic characters. Molecular technology can generate the data required to verify phylogenetic relationships in this artificial classification system, but is subject of the constraints of time, money and expertise. Neither morphological nor molecular based taxonomy is inherently superior. The utilitarian aspect of morphological systematics, in fact, is the great advantage over molecular methods. However, from the viewpoint of applied mycology, the biochemical profiles of these organisms offer the most useful identification system. The taxonomic significance of the results from such investigations and their contribution to a better understanding of the complex situation are undeniable. All earlier views and systems were based on the knowledge and technology available at that time. Current students of this group can similarly only base their views and proposals on the information available. Current knowledge is advanced to what was known then. This will also be true about today’s concepts and those still to come. The now redundant systems were created to serve science and not because of human inadequacies. The nature of these fungi dictates to scientists an arbitrary species concept and user-friendly taxonomic systems. Various opinions about terms, and especially the conidiogenic processes, appear to be confusing, but led to a functional, although phylogenetically inadequate, system. What Kananaskis could not do for phylogenetics, it did for standardization of terms. / Thesis (PhD (Botany))--University of Pretoria, 2005. / Plant Science / unrestricted

Mineral requirements of selected species of aquatic hypomycetesHickman, Don Winston 20 January 2010 (has links)
This study was undertaken to investigate the mineral nutrition of aquatic Hyphomycetes by determining the mineral requirements of several species. On the basis of rapidity and renroducibility of growth, four species were selected, These were Heliscus lugdunensis Webster (Nectria lugdunensis webster), Flagellospora penicillioides Ingold (Nectria penicillioides Ranzoni), Clavariopsis aquatica DeWildeman, and Lunulospora curvula Ingold. These were grown in liquid culture on a rotary shaker at constant temperature.
The containers and other equipment were cleaned by acid washing. When necessary to establish a nutritional reguirement for an element, the nutrient salts were purified by the phosphate adsorption and dithizone methods. In addition to nutrient salts and purified water, the media contained only glucose. Since all the species except Clavariopsis aquatica DeWildeman grew well for many transfers and approximately two years on this completely defined medium, without vitamins or amino acids being provided, it is concluded that they do not require these nutrients.
Whether an element was required, and in what concentration, was decided on the basis of the amounts of growth obtained with various concentrations of the element in the initial media. Growth was measured as the dry weight of the mycelium from 100 ml of medium and the values from four replicates were averaged.
Phosphorus, calcium, nitrogen, zinc, iron, magnesium, and sulfur requirements were demonstrated for all four species. Efforts to demonstrate requirements for potassium were unsuccessful. Manganese toxicity was demonstrated for Clavariopsis aquatica DeWildeman and a manganese requirement was suggested for Flagellospora penicillioides Ingold (Nectria penicillioides Ranzoni). The results suggested a molybdenum requirement for Heliscus lugdunensis Webster (Neetria lugdunensis Webster) and Lunulospora curvula Ingold, a boron requirement for H. lugdunensis and toxicity for C. aquatica, and a copper requirement for F. penicillioides.
Approximately 0.50, 0.25, 0.50-1.00, and 0,.05-0.10 milli-moles per liter of phosphate were required to obtain maximum dry weight yields of Heliscus lugdunensis Webster (Nectria lugdunensis Webster), Flagellospora penicillioides Ingold (Nectria penicillioides Ranzoni), Clavariopsis aguatica DeWildeman, and Lunulospora curvula Ingold respectively. Calcium concentrations of 7.5, 50, 7.5, and 25 milli-moles per liter supported maximum growth of these species in the same order. All four were able to utilize ammonium nitrogen, nitrate nitrogen, or ammonium nitrate to produce about the same amounts of growth. C. aquatica was apparently able to use nitrate nitrogen only in the presence of an unidentified nutrient and this is interpreted as indicating a role for that nutrient in the nitrate metabolism of this species. Fifteen milli-equivalents per liter of ammonium nitrate, ammonium, or nitrate nitrogen was adequate to obtain maximum dry weight yields of H. lugdunensis. Five milli-equivalents per liter of ammonium nitrate, 15 of ammonium, and 35 of nitrate nitrogen supported maximum growth of F. penicillioides. As little as 5 milli-equivalents per liter of ammonium nitrate or ammonium nitrogen was optimal for C. aguatica and 5 milli-equivalents per liter of any of the three nitrogen sources was optimal for L. curvula. The optimal nitrate concentration for C. aquatica was not determined.
There is an obvious advantage to a single medium on which a great number and wide variety of species may be grown. The author is of the opinion that a far greater advantage lies in the use of a completely defined medium on which one or more organisms may be reproducibly grown, Such media are suggested and their employment is strongly urged. Only in this manner can considerable morphological and physiological variations be avoided. / Ph. D.

Previous issue date: 2016-02-17 / CNPQ / Os fragmentos de Mata Atlântica do Nordeste brasileiro representam um abrigo para
a diversidade de espécies e a redução de vários hectares de mata ao longo dos
anos gera perda de diversidade, principalmente, da micobiota microscópica
associada a esses ambientes. O desenvolvimento rural sustentável necessita de
práticas menos agressivas ao ambiente e, dessa forma, os Sistemas Agroflorestais
(SAFs), pela semelhança aos ecossistemas naturais em estrutura e diversidade, têm
papel de destaque como alternativa para produção agrícola. Os ambientes de mata,
assim como os SAFs, além de fornecerem diferentes substratos para a colonização
fúngica, propiciam um ambiente com calor e umidade essenciais para o
desenvolvimento de fungos. A micobiota microscópica em folhas em decomposição
é composta principalmente por fungos conidiais. Esses fungos exibem grande
diversidade de formas e adaptações, estando entre os principais decompositores da
matéria orgânica. Dessa forma, o presente trabalho teve por objetivo realizar um
estudo de diversidade de fungos conidiais e biomassa fúngica em folhedo de
sistema agroflorestal, comparando-o com um fragmento de Mata Atlântica, na região
Norte de Pernambuco. Coletas bimestrais foram realizadas na Mata Atlântica nativa
de Monjope e no Sítio São João – Sistema agroflorestal (ambos em Abreu e Lima -
PE), entre agosto de 2014 e maio de 2015. As amostras de folhedo foram
submetidas à técnica de lavagem em água corrente, colocados em câmaras-úmidas
e incubados em temperatura ambiente por um período de 45 dias, sendo
observados diariamente sob estereomicroscópio. Lâminas semi-permanentes e
permanentes foram confeccionadas com as estruturas reprodutivas para a
identificação morfológica dos espécimes. As lâminas foram depositadas no Herbário
URM da UFPE. A análise da biomassa de fungos no folhedo foi realizada pelo
método de quantificação do ergosterol e a relação entre o teor de ergosterol e a
ocorrência de fungos conidiais foi determinada. Foram registradas ocorrências de 65
táxons de fungos conidiais, incluindo uma nova espécie (Selenodriella amoena) e
uma nova ocorrência para a América do Sul (Linodochium sideroxyli). A
concentração de ergosterol foi diferente entre as duas áreas estudadas nos meses
de out./14, jan./15 e maio/15, sendo maior no SAF em todos os períodos. O teor de
ergosterol da biomassa de fungos no folhedo, em ambas as áreas, possui forte
correlação com a ocorrência dos fungos conidiais. Este estudo contribui para ampliar
o conhecimento da diversidade de fungos conidiais presentes em folhedo em
Pernambuco. / The Brazilian Northeast Atlantic Forest fragments represent a refuge for species
diversity and the reduction of several hectares of forest over the years generates loss
of diversity, especially microscopic mycobiota associated with these environments.
Sustainable rural development requires less aggressive practices to the environment
and thus agroforestry systems (AFS), with their similarity to natural ecosystems in
structure and diversity, have an important role as an alternative for agricultural
production. The forest environments, as well as the SAF’s, provide various substrates
for fungal colonization and an environment with heat and humidity essential for the
development of fungi. Microscopic mycobiota in decaying leaves is mainly composed
of conidial fungi. These fungi exhibit great diversity of shapes and adaptations, being
among the major decomposers of organic matter. Thus, this study aimed to
investigate conidial fungal diversity and fungal biomass in leaf litter of agroforestry
system by comparing it with a fragment of Atlantic Forest in the northern region of
Pernambuco. Every two months, samples were taken in the Monjope native Atlantic
Forest and Sítio São João - Agroforestry system (both in Abreu e Lima - PE) between
August 2014 and May 2015. The litter samples were submitted to the washing
technique in running water, placed in humid chambers, and incubated at room
temperature for a period of 45 days and observed daily under a stereomicroscope.
Semi-permanent and permanent slides were prepared with the reproductive
structures for morphological identification of specimens. The slides were deposited in
the Herbarium URM UFPE. Analysis of the fungal biomass in leaf litter was carried
out using the quantification of ergosterol and the relationship between the ergosterol
content and the presence of fungal conidia was determined. The occurrence of 65
taxa of conidial fungi was recorded, including a new species (Selenodriella amoena)
and a new record for South America (Linodochium sideroxyli). The concentration of
ergosterol was different between the two study areas in the months of Oct. / 14, Jan.
/ 15 and May / 15, being higher in the SAF in all periods. The ergosterol content of
the fungal biomass in leaf litter in both areas has strong correlation with the
occurrence of conidial fungi. This study contributes to the understanding of the
diversity of conidial fungi present in litter in Pernambuco.

Fatores reguladores da decomposição foliar: uma abordagem sobre fragmentadores e decompositores / Regulator factors of leaf breakdown: an approach on shredders and decomposersBiasi, Cristiane 21 February 2017 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / According to the River Continuum Concept, in small rivers, corresponding to ~ 80% of river basins, the main energy source for the trophic chain is the material produced in riparian zones, especially leaves. This material goes through the process of decomposition, which is responsible for the nutrients cycling and maintenance of aquatic communities. In this context, the objective of this study is to investigate the effects of physical, chemical and physiological traits of plant species on microbial activity and fragmentation, and as a consequence on decomposition rates. In the first chapter we investigated the activity of Phylloicus fragmentation in relation to food resources with different leaf traits. We found that the shredders have their food activity stimulated by substrate with less amount of lignin, which facilitates fungus conditioning and promotes the palatability of the detritus. In the second chapter, we investigated the feeding preference and assimilation of C3 and C4 carbon by Phylloicus and Aegla longirostri. We found that the shredders consume more the C4 species, but do not alter its isotopic signature and the intense activity of the hyphomycetes in the leaves C4 stimulated the consumption by the shredders. In the third chapter we investigated the effect of nutrient enrichment on soil and water on leaf nutritional quality and decomposition rates. We showed that the fertilized trees promoted leaves more nutritious than leaves of unfertilized trees. In addition, we found that the effect of nutrient enrichment on water was stronger than the nutrient enrichment of leaves in the decomposition process. Within the three chapters, we verified that the activities of the shredders and fungi are influenced by the characteristics of the leaves and are related to the riparian vegetation, especially by C3 carbon. We verified that the structural compounds are determinant for the microbial colonization and consequently for the fragmentation and litter decomposition. We also verified that the enrichment of nutrients in the water may be more important for the process of leaf decomposition than the nutrients in the leaves. / De acordo com a teoria do Contínuo Fluvial, nos pequenos rios florestados, que correspondem a ~80% das bacias hidrográficas, a principal fonte de energia para a cadeia trófica é o material produzido nas zonas ripárias, especialmente folhas. Este material passa pelo processo de decomposição, que é responsável pela ciclagem de nutrientes e manutenção das comunidades aquáticas. Neste contexto, o objetivo deste estudo é investigar os efeitos dos traços físicos, químicos e fisiológicos das espécies vegetais na atividade de microrganismos e invertebrados decompositores, e como consequência nas taxas de decomposição. No primeiro capítulo investigamos a atividade de fragmentação de Phylloicus frente a recursos alimentares com características foliares diferentes. Nós constatamos que os fragmentadores têm sua atividade alimentar estimulada por substrato com menor quantidade de lignina, o que facilita o condicionamento por fungos e promove a palatabilidade do detrito. No segundo capítulo, investigamos a preferência alimentar e assimilação C3 e C4 por Phylloicus e Aegla longirostri. Constatamos que os fragmentadores consomem mais a espécie C4, porém não alteram sua assinatura isotópica. E a intensa atividade dos hifomicetos nas folhas C4 estimulou o maior consumo pelos fragmentadores. No terceiro capítulo investigamos o efeito do enriquecimento de nutrientes no solo e na água na qualidade nutricional das folhas e nas taxas de decomposição. Evidenciamos que as plantas fertilizadas geraram folhas mais nutritivas que as não fertilizadas. Além disso, averiguamos que o efeito do aumento de nutrientes na água foi mais forte do que o efeito de nutrientes das folhas no processo de decomposição. Com os três capítulos verificamos que as atividades dos fragmentadores e fungos são influenciadas pelas características das folhas e estão relacionadas com a vegetação ripária, especialmente por carbono C3. Constatamos que os compostos estruturais são determinantes para a colonização microbiana e por consequência para a fragmentação e decomposição foliar. Verificamos também que o enriquecimento de nutrientes na água pode ser mais importante para o processo de decomposição foliar do que os nutrientes nas folhas.

Previous issue date: 2016-09-05 / CAPES / The Atlantic Forest is one of the ecosystems richest in biological diversity of the planet and is directly responsible for the quality of life of thousands of Brazilians. Among the species present in the Atlantic including PNM Curi?, Paracambi, R.J., are present cercosporoid fungi, represented by the genus Cercospora. Are plant parasitic fungi, polyphagous and cosmopolitan, causing leaf spots, as well as in flowers, fruits and cereal seeds, vegetables, ornamental plants of forest trees and grasses. These fungi were quite challenged in recent years, mainly because of its immense morphological variation and studies based on nucleic acid sequences, have become widely used for the elucidation of several doubts in its taxonomy, then for the knowledge and description of new species in new hosts are so important to discuss their morphology as well as studies using molecular data for this group. This work was developed aiming to increase the knowledge of biodiversity of cercosporoid fungi associated to different botanical families from the Atlantic Forest in the state of Rio de Janeiro. From October, 2014 to May, 2016 several collections of plants with leaf spot symptoms were collected in Atlantic Forest areas, especially in the PNM Curi?, Paracambi, RJ. and areas of the municipality of Serop?dica, RJ. and taken to DENF laboratories (Mycology) / UFRRJ, and studied using optical, dissecting and scanning electron microscope techniques and several attempts of isolation in axenic culture media were made, for their in vitro characterization and extraction of DNA for molecular characterization studies.
