臺灣黏菌（十三）：一新記錄種及一新變種

Myxomycetes of Taiwan XIII. One New Record and One New Variety

本文描述兩絨泡黏菌科的成員，並以光學顯微鏡和掃描式電子顯微鏡的觀察來圖示。其中白頭高杯黏菌無柄變種（Craterium leucocephalum Ditmar var. sessile Liu, Huang, and Chang）為世界性的新變種，其子實體自野外直接採得，孢子囊具有如下的特徵：無柄、長圓桶形或倒圓錐形、白色的頂蓋。而光孢絨泡黏菌（Physarum laevisporum Agnihothrudu）是採用濕室培養得到，為臺灣的新紀錄種。標本皆存放於台大植物系菌類標本室。

One new record and one new variety of Physaraceae (Myxomycetes) are described and illustrated by light and scanning electron microscopy. The new variety, Craterium leucocephalum var. sessile Liu, Huang, and Chang, was collected from the field. This taxon is characterized by having sessile sporangia in cylindric to obconic shape, which at the top is white as that of the type variety leucocephalum. The new record, Physarum laevisporum Agnihothrudu, was harvested from moist-chamber cultures. Specimens of these two taxa are deposited in the Mycological Herbarium, Department of Botany, National Taiwan University.
