Hyphomycetes were abundant on plant debris and play a part on decomposition of these substrates. Samples of Caesalpinia echinata leaf litter were collected in two areas of State of São Paulo, at "Parque Municipal do Ibirapuera" and "Reserva Biológica de Mogi-Guaçu", from February 2005 to February 2006. The leaves were prepared by washing with serial changes of sterile distilled water and incubated in moist chambers at environment temperature. Third-two Hyphomycetes were isolated. Of these, four species are described for the first time to Brazil, seven are new records to São Paulo State and seventeen are cited for the first time to Brazil-wood leaf litter.
