Hyphomycetes in rain water draining from intact trees.

The authors investigated Hyphomycetes in rain water flowing down from leaves of 10 gymnospermous and 10 angiospermous tree species in northeastern Poland. The presence of 57 Hyphomycetes species was noted. Only 17 species were found to develop both on gymnospermous and angiospermous tree species out of 57 found in rain water flowing down the trees. 16 Hyphomycetes species were observed in rain water flowing down the angiospermous trees, while 24 species in the water from the gymnospermous trees. 13 Hyphomycetes species were recorded for the first time from Poland.
