Richness of ingoldian fungi and facultative aquatic fungi in the Parque Municipal da Aclimação, São Paulo, São Paulo State, Brazil

ABSTRACT

In the Parque Municipal da Aclimação, submerged mixed leaf litter samples were monthly collected from March 2007 to June 2009 at three sites of a lake where some abiotic variables were measured. In the laboratory, the leaves were washed, fragmented into aliquots (1 cm2), incubated in sterile distilled water for 30 days at 22 ºC, and prepared on slides to be microscopically analyzed. Based on morphological characteristics, 26 fungal taxa were identified, being 16 ingoldian fungi with predominance of Lunulospora curvula Ingold, Triscelophorus monosporus Ingold, and Tripospermum myrti (Lind.) S. Hughes, and 10 facultative fungi, with Cylindrocladium scoparium Morgan, Endophragmiella sp., and Beltrania rhombica Penz as the most common taxa. The number of fungal taxa was not very different in the comparison of the main climatic seasons, but was higher at the sites next to the exit of the water treated by flotation than at a site where a more intense monitoring of the water quality becomes recommendable.
