Phylogenetic placement of new lichenicolous basidiomycetes in the corticioid and cantharelloid clades.
THE vast majority of described lichenicolous fungi are ascomycetes or heterobasidiomycetes, but some of the most familiar of these fungi are homobasidiomycetes. Recent phylogenetic studies of homobasidiomycetes (Corticiaceae s. lat. and others) reveal at least 12 independent lineages, of which five are now known to contain lichenicolous fungi. Many of these fungi form conspicuous sclerotia or bulbils. Two of the most speciose of these bulbilliferous groups are the Marchandiomyces species in the ‘corticioid’ clade of homobasidiomycetes and Burgoa-like species in the ‘cantharelloid’ clade. New species in each clade have recently been described and include some new to North America. These fungi exhibit a wide variety of nutritional modes, including lichenicolous, lignicolous, muscicolous, and corticolous members. In each clade there is also evidence for evolutionary linkages with certain groups of basidiolichens.[c.e.:srb]
