Fungi in the litter of Andreadoxa flava and Nectandra membranacea in Southern Bahia

Abstract

Abstract In the present research were studied fungi on the litter of Andreadoxa flava and Nectandra membranacea, in a remaining area of the Atlantic Forest in Ilhéus, BA. The mycota of those plants had not been studied. Samples were obtained in three collections between October 2018 and July 2019, during which 20 leaves at different stages of decomposition were collected per plant species. The leaves were washed and stored in wet chambers. Fungal preparations were used for microscopic analysis and identification of species. A total of 25 genera and 32 fungal species were found, 26 in the litter of A. flava and 22 of N. membranacea. Sixteen genera were associated with both plants. Microcallis was identified for the first ever associated with A. flava, a species native to the Atlantic Forest, and the taxon Thozetella falcata, was found for the first time in Bahia in the same plant. This is the first report of Parasympodiella lauri on N. membranacea in Brazil. The mycota found was analyzed taxonomically and for its diversity. Further studies on the mycota associated with the two plants must be carried out, particularly for A. flava as it is nearly extinct in nature.
