摘要：Myxomycetes (plasmodial slime molds) are fungus-like protists that are often understudied in a biodiverse country such as the Philippines. As such, the purpose of the project described herein was first to document the species of myxomycetes collected in Mt. Arayat National Park, Pampanga, Philippines and then to develop an interactive database for these organisms using DELTA software. These are the first reports of myxomycetes from Mt. Arayat. A total of 33 species were recorded for the two slopes of the mountain during the wet and dry seasons.Five species of myxomycetes (i.e., Arcyria afroalpina , Collaria arcyrionema , Craterium concinnum , Enerthenema papillatum and Licea biforis ) were new records for the Philippines. As a second component of the project, interactive identification guides were generated from 67 taxonomic characters using the DELTA software. The interactive database recognized spore appearance, colour of the spores by transmitted light, fruiting body colour and the outline of the sporotheca as the most useful characters in recognizing the species of myxomycetes known from Mt. Arayat. The interactive database generated in this study is the first effort along these lines for the Philippines and for Southeast Asia.
