Previous issue date: 2013-03-18 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Fungi of the family Nidulariaceae or bird s nest fungi present a vase-shaped basidiomata
with the wall surface smooth or striated lengthwise and internal structures resembling small
bird eggs in a nest, the peridioles. Among the five genera that comprise the group, the more
representative is Cyathus Haller: Pers. The Brazilian Northeast region shows major
importance for the world s diversity by containing a Brazilian unique and exclusively
phytoecological domain, the Caatinga, which lacks particular attention regarding
macrofungi. Although the gradual growth of knowledge in recent years, studies are still
insipient in the Caatinga domain. Between their various vegetal formations are the Brejos
de Altitude , described as islands with moist perennial vegetation, low soil fertility and
annual precipitation of 900 1.300 mm. This study aimed to evaluate the taxonomic
richness of Nidulariaceae fungi in Caatinga s areas of Northeastern Brazil, describing and
identifying species, as well as expanding the collection of Herbarium UFRN Fungos. For
description of Nidulariaceae fungi was followed the proposed by specialized literature in
the group. We have found and described 10 species of the genus Cyathus, namely: C. earlei
Lloyd, C. gayanus Tul. & C. Tul., C. gracilis H.J. Brodie, C. intermedius (Mont.) Tul. & C.
Tul., C. limbatus Tul. & C. Tul., C. montagnei Tul. & C. Tul., C. pallidus Berk. & M.A.
Curtis, C. poeppigii Tul. & C. Tul., C. striatus (Huds.) Willd. and C. tr?plex Lloyd. Beyond
these have been described four new species to science: Cyathus calvescens R. Cruz &
Baseia sp. nov., C. hortum R. Cruz & Baseia sp. nov., C. magnomuralis R. Cruz & Baseia
sp. nov. and C. parvocinereus R. Cruz & Baseia sp. nov. Two samples were identified only
to genus level. No member of Mycocalia J.T. Palmer, Nidula V.S. White, Nidularia Fr. and
Crucibulum Tul. & C. Tul. has been found, however the results were extremely valuable for
being an unprecedented work in Caatinga, and importante tool for implementation of
conservation projects and sustainable utilization of this domain / Os Fungos da fam?lia Nidulariaceae, ou fungos ninho-de-p?ssaro , apresentam basidiomas
em forma de vaso, com a superf?cie da parede lisa ou estriada longitudinalmente e
estruturas internas que se assemelham a pequenos ovos de p?ssaros dentro de um ninho, os
perid?olos. Dentre os cinco g?neros que comp?em o grupo, o mais representativo ? Cyathus
Haller: Pers. O Nordeste Brasileiro apresenta grande import?ncia para a diversidade
mundial por conter um dom?nio fitoecol?gico ?nico e exclusivamente brasileiro, a
Caatinga, o qual carece de aten??o especial quanto aos macrofungos. Apesar do
crescimento gradual de conhecimento nos ?ltimos anos, os estudos ainda s?o incipientes no
dom?nio Caatinga. Entre as suas diversas forma??es vegetais existem os Brejos de Altitude,
caracterizados como ilhas ?midas de vegeta??o perenif?lia, solo de baixa fertilidade e
precipita??o anual entre 900 1.300 mm. Este trabalho visou levantar a riqueza taxon?mica
dos fungos nidulari?ceos em ?reas de Caatinga do Nordeste Brasileiro, descrevendo e
identificando esp?cies, bem como ampliando a cole??o do herb?rio UFRN Fungos. Para
descri??o de fungos nidulari?ceos seguiu-se a proposta em literaturas especializadas do
grupo. Foram encontradas e identificadas 10 esp?cies do g?nero Cyathus, a saber: C. earlei
Lloyd, C. gayanus Tul. & C. Tul., C. gracilis H.J. Brodie, C. intermedius (Mont.) Tul. & C.
Tul., C. limbatus Tul. & C. Tul., C. montagnei Tul. & C. Tul., C. pallidus Berk. & M.A.
Curtis, C. poeppigii Tul. & C. Tul., C. striatus (Huds.) Willd. e C. tr?plex Lloyd. Al?m
dessas foram descritas 4 novas esp?cies para a ci?ncia: Cyathus calvescens R. Cruz &
Baseia sp. nov., C. hortum R. Cruz & Baseia sp. nov., C. magnomuralis R. Cruz & Baseia
sp. nov. e C. parvocinereus R. Cruz & Baseia sp. nov. Duas amostras foram identificadas
apenas a n?vel de g?nero. Nenhum membro de Mycocalia J.T. Palmer, Nidula V.S. White,
Nidularia Fr. e Crucibulum Tul. & C. Tul. foi encontrado, contudo os resultados foram de
grande valia por ser um trabalho in?dito na Caatinga e importante subs?dio para aplica??o
de projetos de conserva??o e utiliza??o sustent?vel do dom?nio
