Endophytic species from spp. in China and Northern Thailand.

Species of are commonly found in many plant hosts as pathogens, endophytes and occasionally saprobes. Twenty-two strains were isolated from three species - , and , as well as three unidentified species. The taxa were identified using morphological characterisation and phylogenetic analyses of ITS, GAPDH, ACT and ß-tubulin sequence data. This is the first time to identify endophytic fungi from orchids using the above method. The known species, , , and were identified as fungal endophytes of spp., along with the new species, , , , and , which are introduced in this paper. One strain is recorded as an unidentified species. Corn meal agar is recommended as a good sporulation medium for species. This is the first report of fungal endophytes associated with and . , , and are new host records for Thailand.
