多囊蓋壺菌（Chytriomyces multioperculatus）形態及游孢子超微結構研究

Morphology and Zoospore Ultrastructure of Chytriomyces multioperculatus (Chytridiales)

本文描述一種臺灣新紀錄多囊蓋壺菌（Chytriomyces multioperculatus），使用光學顯微鏡及掃描式電子顯微鏡觀察菌體外部形態，並以穿透式電子顯微鏡觀察游孢子內部的微細構造。經由純培養，游孢子發育為成熟的菌體，游孢子囊具有2個以上的釋放孔，游孢子釋出後囊蓋脫落或垂掛在孔緣。游孢子超微結構為本菌種首次報導，顯示基本上與Lobulomyces（Lobulomycetales）游孢子之特徵相似，不具有微小管束與梳狀體。

Chytriomyces multioperculatus Sparrow and Dogma is a new record of Taiwan. It was isolated from water of a pond, and pure cultured on 1/4YpSs medium. The mature zoosporangium produced numerous operculate discharge papillae. The opercula either separated from or remained attached to the rim of the exit orifices. The zoospore ultrastructure of C. multioperculatus is similar to the zoospore characteristic of Lobulomyces (Lobulomycetales).
