Physalacria corticola, P. stilboidea, and Stilbum vulgare, Three Sphaeropedunculate Basidiomycota New to Taiwan, with Notes on Stilbum erythrinae

Three saprotrophic species of Basidiomycota forming sphaeropedunculate basidiomata, Physalacria corticola, hitherto only known from Singapore, Physalacria stilboidea known from New Zealand and United Kingdom, and Stilbum vulgare, hitherto not recorded for Asia, were found on dead branches and leaves in Taiwan. These species are described and illustrated in detail. Based on type study of Stilbum erythrinae Hansf., this species is tentatively transferred to Chionosphaera.
