(Microscopical fungi of the Atlantic rainforest of Paranapiacaba, São Paulo, Brazil). In the Atlantic rainforest of Paranapiacaba, state of São Paulo, 1770 occurrences of different fungal taxa were registered from July 1988 to May 1990. For stream water 319 occurrences were reported, 405 for the soil, 565 on submerged leaves of Alchornea triplinervia (Spreng.) M. Arg., and 481 on leaves placed on the soil surface. Mastigomycotina was represented by 20 taxa with 316 occurrences, Zygomycotina by 13 taxa with 266 occurrences, Deuteromycotina by 82 taxa with 1107 occurrences, and Ascomycotina by eight taxa with 81 records. The fungi were isolated by the leaf disk washing method, soil plate method, and baiting with chitinic, cheratinic and cellulosic substrates. The decomposing leaves of A. triplinervia supported the highest number of fungal taxa and total occurrences, followed by the soil and stream water.
