摘　　要：For the first time,assemblage and diversity of aquatic hyphomycetes were investigated in four lateritic cave streams of the southwest coast of India.This study includes physicochemical features of cave habitats and stream waters.Species richness,diversity and equitability of aquatic hyphomycetes in foam,water,leaf litter and woody litter(bark and cambium)have been investigated.These cave streams yielded up to 21 species of aquatic hyphomycetes,which is comparable to the population in nearby streams.The leaf litter of cave streams consist of highest number of species,while it was the lowest in the foam samples(15 vs.7 spp.).Cave stream water,bark and cambium consist of 14,11 and 9 species,respectively.Simpson’s and Shannon’s diversities were the highest in water samples,while the Pielou’s equitability was highest in foam samples.The species richness as well as the core-group(highly frequent)aquatic hyphomycetes are comparable with nearby streams.Actinospora megalospora,Anguillospora angulata,A.crassa,Condylospora spumigena,Ingoldiella fibulata and Trinacrium subtile were the new records to the coastal region of southwest India.
