Two new records of freshwater Sordariomycetes, Sporoschisma chiangraiense (Chaetosphaeriales) and Trichoderma pinicola (Hypocreales), from the Philippines

This is the authors' abstract. We don't add key points for this paper.

One of our studies on lignicolous aquatic fungi in the Philippines yielded two new records of freshwater Sordariomycetes in the genera Sporoschisma and Trichoderma. The newly collected specimens, UPVMI 24–0003 and UPVMI 24–0004, exhibit morphological similarities to the holotypes of Trichoderma pinicola (SFC 20130926-S233) and Sporoschisma chiangraiense (MFLU 18–1722), respectively. Combined ITS-TEF1-α phylogenetic analysis showed that UPVMI 24–0003 clustered with the ex-type strain of T. pinicola (KACC 48486), and with T. simplex (HMAS 248842) as a sister taxon. The isolate UPVMI 24–0004 grouped with three strains of S. chiangraiense (MFLUCC 18-0703, MFLUCC 18-0336, and GMB0090), with 97% ML and 1.00 BYPP bootstrap supports in the ITS phylogeny. We provide detailed descriptions and illustrations for both T. pinicola and S. chiangraiense, along with a synopsis of morphological characters for freshwater Sporoschisma species.
