Three new species of Trechispora from Northern and Northeastern Thailand

During the rainy season in Thailand, specimens of coral fungi were collected from community forests in Chiang Mai and Kalasin Provinces. The species presented here, Trechispora khokpasiensis , T . saluangensis , and T . sanpapaoensis are characterized by coralloid basidiomata and described as new taxa in Hydnodontaceae ( Trechisporales ) based on analyses of their morphological characters and phylogenetic relationships from the nuclear ribosomal large subunit (LSU) as well as the internal transcribed spacer regions’ (ITS) sequence data. Morphological descriptions and illustrations, including color photographs, line drawings and phylogenetic trees, are presented. Comparisons with similar species are also provided.
