A rapid survey of myxomycetes associated with different substrata in Luzon Island, Philippines

The tropical habitats in the Philippines have many microhabitats (= substrata) that are suitable for myxomycetes. The present study looked at myxomycetes occurring in these microhabitats collected from selected sites in Luzon Island, Philippines. A total of 27 species belonging to 13 genera were identified from 142 positive moist chamber cultures which were prepared from ten microhabitats. The highest number of species were recorded in grass litter with 14 species, followed by decayed vines (12), aerial leaf litter of Musa paradisiaca L. (8) and Chromolaena odorata (L.) King & Robinson (7), plant inflorescence (6), decayed fern leaf (5), ground leaf litter of Swietenia macrophylla King (4), decayed twigs (3), dung (3), pine-needle leaf (2), and broad leaf litter (2). Arcyria cinerea, Diderma hemisphaericum and Stemonitis fusca were the most abundant species of myxomycetes.
