陽明山國家公園紗帽山地區真粘菌生物多樣性之研究

Biodiversity of the True Slime Molds (Myxomycetes) at Mt. Shamao of the Yangmingshan National Park

真黏菌為森林中常見的棲息生物，然針對物種資源豐富的陽明山地區，所做的真黏菌生態調查卻不多。本實驗自2000年8月至2001年8月，於陽明山國家公園紗帽山地區以直接採集和濕室培養收集標本。總計採收真黏菌標本243份，共41種又3變種。其中以亮皮黏菌（Lamproderma scintillans（Berk. & Br.）Morgan）、半圓雙皮黏菌（Diderma hemisphaericum（Bull.）Hornem）、墊形雙皮黏菌承名變種（Diderma effusum var. effusum（Schw.）Morgan）為此區優勢種。而白頭高杯黏菌無柄變種（Craterium leucocephalum var. sessile Liu, Huang & Chang）為世界性新變種，另粗柄亮皮黏菌（Lamproderma muscorum（L.）Hagelst.）和光孢絨泡黏菌（Physarum laevisporum Agnihothrudu）為台灣新紀錄種。 A monthly survey was conducted to investigate the true slime molds (Myxomycetes) at Mt. Shamao of the Yangmingshan National Park from August 2000 to August 2001. A total of 41 specices and three varieties were identified from 243 specimens collected from the field or cultivated by the moist-chamber technique. Lamproderma scintillans (Berk. & Br.) Morgan, Diderma hemisphaericum (Bull.) Hornem, and Diderma effusum var. effusum (Schw.) Morgan were the dominant species. Lamproderma muscorum (Lev.) Hagelst. and Physarum laevisporum Agnihothrudu were found to be the new records to Taiwan, while Craterium leucocephalum var. sessile Liu, Huang & Chang was a new variety.
