碩士 / 國立臺灣海洋大學 / 海洋生物研究所 / 98 / Traditionally, asexual fungi were classification in the Deuteromycota. For the last 2 decades, asexual fungi have been found to be in artificial assembly and most of them belong to the Ascomycota and Basidiomycota. A total of 94 species of marine asexual fungi have been discovered and only 29 species have been connected to their sexual counterparts.
In this study, phylogenetic analysis of the small (SSU) and large (LSU) subunit ribosomal DNA sequence was used to resolve : (1) the higher classification of the marine Trichocladium species, (2) the monophyly of the marine Trichocladium species, (3) relationships between marine Trichocladium species, and (4) if the characteristics of the conidia are important characters for the delineation of marine Trichocladium species. Bactrodesmium linderi was included as it was once classified as a Trichocladium species.
Trichocladium asperum (type species) resides in the Sordariales while all of the marine Trichocladium species used in this study were not monophyletic with the type species. Trichocladium achrasporum, T. constrictum and T. melhae clustered within the Halosphaeriaceae (Order Microascales) , while T. nypae, T. alopallonellum and T. lignicola grouped with taxa in the TBM clade (Hypocreomycetidae). Bactrodesmium linderi belonged to the Hypocreales but did not group with any known family. The morphology of the conidia is inferred to be a good character to differentiate different Trichocladium species other related taxa of the marine Trichocladium should be sequenced before any taxonomic decision is made.
