Abstract

One new species and one new record in the family Physaraceae are described and illustrated by light and scanning electron microscopy. Badhamia formosana Liu and Chen sp. nov. was found on mosses that grew on barks of dead wood or on barks of living trees of broad leaves. This species is characterized by the stipitate, white and limy fruiting bodies, large spores and limy capillitium. Fruiting bodies of Physarum braunianum, a new record of Taiwan, were obtained from moist-chamber culture of leaf litters. They are easy to be recognized by the brownish orange-colored sporangia which are sessile and always constricted at base, and capillitium with angular lime nodes often in concolorous with the peridium.

中文摘要

本篇描述絨泡黏菌科的一個世界性新種及一個台灣新紀錄種，並加上光學和掃描式電子顯微鏡所拍攝的相片。台灣鈣絲黏菌 (Badhamia formosana Liu and Chen sp. nov.) 為一世界性新種，是在腐木樹皮上的蘚苔類植物或闊葉樹樹皮上所發現，此種黏菌的特徵是：子實體有柄，且覆有白色的石灰質顆粒，孢子大型和石灰質的細毛體。紅褐絨泡黏菌(Physarum braunianum)為台灣新紀錄種，是以枯枝落葉做濕室培養所得，其易辨認的特徵是：孢子囊呈橘褐色，無柄，其基部收縮，且細毛體的石灰節常和周膜色澤相近。
