Abstract

A total of 524 bark samples were collected from five species of Pinus trees in the central and northern Taiwan. And 237 corticolous Myxomycetes were then obtained one to two monthes after the preparation of moist-chamber cultures of the bark sample. They distribute in eleven genera, i.e. Arcyria, Clastoderma, Comatricha, Cribraria, Diderma, Echinostelium, Enerthenema, Licea, Macbrideola, Physarum, and Trichia. The species of the Myxomycetes and their substrate living trees are shown in a table. Among the twenty four species identified seven are new to Taiwan and two are rediscovered for the first time since the publication of Nakazawa’s list in 1929. the newly recorded species are Comatricha acanthodes Alexop., and Physarum auriscalpium Cooke. The two rediscovered species are Arcyria pomiformis (Leers) Rost. and Physarum cinereum (Batsch) Per. A detailed descriptions and pictures of the above nine species are provided. Two specimens of the genera Diderma and Macbrideola manifesting unusual and unique features may upon further study warrant descriptions as new taxa.

中文摘要

以台灣地區以北、中部五個地區所生長的五種松屬植物為取樣對象，採取樹皮，進行潮濕培養，共取524份樣品，觀察期一至二月，共收得黏菌標本237份，荊鑑定，分屬於11屬26種，其學名與樹種來源以表列出，其中七種為台灣新紀錄種分別為Cribraria confusa Nann.-Brem., Licea capitata B. Ing & McHuugh, Licea kleistobolus Martin, Physarum auriscalpium Cooke, Comatricha acanthodes Alexop., Comatricha lurida A. Lister, Macbrideola martini (Alexop & Beneke.) Alexop. ;二種為只有日本人有採集紀錄，至此次調查在發現者，分別為Arcyria pomiformis (Leers) Rost., Physarum cinereum (Batsch) Per.; 二種為未定名種，分屬於Diderma 和Macbrideola二屬；本文除詳述新紀錄種型態特徵外，並提供圖片以為參考。
