Additions to Trechispora and the status of Scytinopogon (Trechisporales, Basidiomycota)

Three new species of Trechispora from Brazil, T. copiosa, T. gelatinosa, and T. termitophila, are described and illustrated. The new species are microscopically similar to the known Trechispora species, but differ by having coralloid basidiomata and would traditionally have been placed in Scytinopogon. Phylogenetic analyses based on nuc rDNA ITS1-5.8S-ITS2 (ITS) and nuc 28S rDNA (28S) regions place the new species and other publicly available sequences identified as Scytinopogon firmly within a strongly supported Trechispora clade that also includes the type species of Trechispora. Scytinopogon is synonymized with Trechispora and the new combinations T. chartacea, T. havencampii, T. minispora, T. pallescens, and T. papillosa are proposed.
