The rich vegetation of volcanic forest offers a unique habitat to explore myxomycetes (slime molds). In this study, the occurrence and diversity of myxomycetes in forest areas of Taal Volcano Crater Rim (Mt. Makulot) and Napayong Island in Taal Lake are reported. Decayed aerial and ground leaf litter, twigs, and woody vines collected from the study areas were used to prepare 1,110 moist-chamber cultures. A total of 35 species belonging to 14 genera were collected. These slime molds were identified as species of Arcyria, Ceratiomyxa, Clastoderma, Collaria, Comatricha, Cribraria, Diachea, Diderma, Didymium, Hemitrichia, Lamproderma, Perichaena, Physarum and Stemonitis. Five species were unique to Mt. Makulot while seven species were exclusively recorded in Napayong Island. Napayong Island also had a higher species diversity as compared to Mt. Makulot. In terms of substrate types, highest species diversity was recorded in ground litter collected in Napayong Island. This study is the first listing of species of myxomycetes in Napayong Island, a small island within a lake within an island.
