摘要

Pseudozyma屬為黑穗菌科無性世代之類酵母真菌，大部分的種分離自植物組織，在台灣自合歡花分離到Pseudozyma分離株，已寄存於食品工業發展研究所生物資源保存及研究中心，編號為BCRC33871，依據形態特徵、生理生化特性及ITS1-5.8S-ITS2 rDNA序列分析結果，鑑定種名為P. antarctica，為台灣新紀錄種。此外本文利用生理生化特性及rDNA 序列分析資料探討P. antarctica之種內及近似種間的差異，並討論用以區分P. antarctica與近似種之關鍵性特徵。

The genus Pseudozyma is an anamorph that belongs to the Ustilaginales. Pseudozyma species are unusual yeast-like fungi and are most frequently isolated from plant materials. The Pseudozyma strain, BCRC 33871, was isolated from the flower of Albizia julibrissin in Taiwan. BCRC 33871 was identified as P. antarctica and described based on morphological, physiological, and molecular data. This discovery marked the first finding of this species in Taiwan. To ensure correct identification, the intraspecific variations of P. antartica were illustrated based on physiological characteristics and phylogenetic analysis of ITS1 and ITS2 rDNA sequences. Additionally, distinguishing characteristics of P. antartica and other related species were discussed.
