Abstract

Collections of submerged wood in streams in Prachuap Khiri Khan Province, Thailand yielded three sporoschisma-like taxa. Morphological examination and phylogenetic analysis of LSU sequence data support the separation of two isolates as new species (S. palauense and S. longicatenatum) and the other as collection of S. hemipsila. The sexual morph (Melanochaeta) is again linked to the asexual genus Sporoschisma by molecular data. The new species are introduced with descriptions and illustrations and compared with the most similar species.
