A preliminary report on soil dematiaceous hyphomycetes from the three river gorge regions in eastern Tibet
3 RESULTS
A total of 47 isolates of soil dematiaceous hyphomycetes belonging to 29 species in 15 genera were found from 30 soil samples collected in the gorge regions in eastern Tibet. Most of the genera and species found are new for this region. Among them Eladia tibetensis is a new species, and Scytalidium acidophilum and S. circinatum are new records to China.
