 Many are yeasts, collectively called basidiomycetous yeasts to differentiate them from ascomycetous yeasts in the Ascomycota.Aside from yeast anamorphs, and uredinia, aecia and pycnidia, some Basidiomycota form other distinctive anamorphs as parts of their life-cycles.Examples are "Collybia tuberosa" with its apple-seed-shaped and coloured sclerotium, "Dendrocollybia racemosa"  with its sclerotium and its "Tilachlidiopsis racemosa" conidia, "Armillaria" with their rhizomorphs, "Hohenbuehelia"  with their "Nematoctonus" nematode infectious, state and the coffee leaf parasite, "Mycena citricolor" and its "Decapitatus flavidus" propagules called gemmae.
