SummaryRecent attention has been given to terrestrial and marine manglicolous fungi because of mangrove tree mortalities. However, this mycobiota in many Caribbean Islands is practically unknown. The halotolerant fungus Asteridiella sepulta, (Pat.) Hansf. (Ascomycota, Meliolaceae), which is one of many species that form sooty mould, has been isolated from leaves surfaces of Avicennia germinans, (L.) Stearn in southwestern Puerto Rico. In this study of A. germinans, we found the planthopper Petrusa marginata, (Brunnich) (Homoptera, Flatidae) excretes a sugary honeydew upon which the dematiaceous mycelium of A. sepulta, grows. Although A. sepulta, has been previously collected on A. germinans, the association of the fungus and the planthopper in black mangrove was not previously reported. Asteridiella sepulta, produces a flat colony with a spongy subiculum on surfaces of leaves, twigs, and small branches of A. germinans. |
