Three coralloid species of the genus Trechispora (Trechisporales, Basidiomycota) in China: two newly discovered taxa and one reported for the first time.

Two new species of Trechispora indigenous to southern China, T.laxa and T.tongdaoensis , are described and illustrated, and the first record of T.khokpasiensis in China is reported. Molecular phylogenetic analyses of the concatenated nuclear rDNA ITS1-5.8S-ITS2 and nuclear large subunit sequences supported the inclusion of the three species within the Trechispora clade, together with species formerly classified in Scytinopogon . The new species are similar in micromorphology to species of Trechispora (as traditionally circumscribed) but are distinguished by having coralloid basidiomata. A key to the known coralloid Trechispora species in China is provided.
