title: Putative basidiomycete teleomorphs and phylogenetic placement of the coelomycete genera: Chaetospermum, Giulia and Mycotribulus based on nu-rDNA sequences.
abstract: 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.
