Comparative Study of Freshwater Hyphomycetes Resource in Heilong Stream during the Rainy Season
and Dry Season in Cangshan Mountain at Dali

Abstract

Abstract:

Objective: To investigate the diversity of freshwater hyphomycetes from Heilong Stream and compare their differences in
occurrence during the dry season and rainy season. Methods: 50 samples were collected from each season, moist chamber incubation
methodwasusedtoincubatethefungiandthefunguswereidentifiedbasedonthemorphologicalcharacters. Results: Atotalof48speciesof
freshwater hyphomycetes were identified: 30 species from dry season, 23 species from wet season. Ellisembia bambusicola, Helicosporium
guianense,Helminthosporium velutinum,Phaeoisaria clematidis,Rhinocladiella schulzerii werefoundduringboththeseasons.Thediversity
index of freshwater fungi at dry season is higher than wet season（3.67 vs 2.32）. Conclusion: The diversity of freshwater hyphomycetes in
HeilongStreamcloselyrelatedtotheseasonchangingandmorespeciesdiversitywasobservedduringdryseason.

Key words: freshwater hyphomycetes, Heilong Stream, dry season, wet season, submerged decayed wood
