Genus Dictyoarthrinium is reviewed. Dictyoarthrinium synnematicum, collected on decaying banana leaves in Thailand, is illustrated, described as a new species and compared with related taxa. The fungus differs from other Dictyoarthrinium species in having a synnematous structure. This species is the first synnematous record of an anamorphic fungus with basauxic conidiophores. A key to species of Dictyoarthrinium is provided. 相似文献

Few basidiomycetes are known to have a coelomycete anamorph. The partial SSU and LSU of nu-rDNA of three coelomycete genera (Chaetospermum, Giulia, Mycotribulus) were sequenced to determine their phylogenetic relationship. M. mirabilis was well placed in the Physalacriaceae, Agaricales, whereas G. tenuis clusters with the Corticiaceae, Corticiales. C. camelliae and C. artocarpi form a close relationship with the Sebacinaceae, Sebacinales. Although morphologically these coelomycetes are pycnidial and with appendaged conidia, they show no consistency in their phylogenetic relationship, belonging to disparate major taxonomic groups with putative teleomorphs in the Agaricales, Corticiales and Sebacinales. Further molecular studies of coelomycetes may be rewarding to evaluate their phylogenetic affinities. 相似文献

The phylogenetic relationship of the coelomycete genus Infundibulomyces with cupulate conidiomata was assessed by ribosomal DNA sequences of partial small subunit (SSU) and partial large subunit (LSU) regions using maximum parsimony and Bayesian analysis. The genus has no known teleomorph. A new species, Infundibulomyces oblongisporus, is described from collections on a senescent angiosperm leaf from Thailand based on morphological and phylogenetic evidence. Both Infundibulomyces species form a monophyletic group in the Chaetosphaeriaceae (Chaetosphaeriales, Sordariomycetidae) with Dictyochaeta simplex as a sister clade. Chaetosphaeriaceae with a coelomycete anamorph has not been reported previously. 相似文献

Taeniolella rudis, with secondary sympodioconidia, is illustrated and described and its taxonomic assignment evaluated. A second new species,
Taeniolella longissima, is described and illustrated. The ecological role of these fungi in the colonization of wood in freshwater habitats is discussed.
