台灣蕉孢殼菌科真菌研究

Abstract

蕉孢殼菌科 (Diatrypaceae) 真菌屬於子囊菌門 (Ascomycota)，為核囊菌綱 (Pyrenomycetes) 之一類，主要辨識特徵為炭質化的子實體，瓶狀的子囊殼以及臘腸狀的子囊孢子。本研究調查台灣地區蕉孢殼菌科真菌的種類，主要鑑定特徵依據野外採集標本上有性構造之形態特徵及培養後所產生之無性世代形態特徵，並以ITS分子序列作為確認物種的輔助工具。在本研究中，共發現30種蕉孢殼菌科之真菌， 其中包含15種未曾描述過的物種。在這些物種中，包含10種Diatrype，為 D. chlorosarca、D. enteroxantha、D. hypoxantha、D. microstroma、D. mindanaensis、D. cf. stigmaoides、D. sp. 1、D. sp. 2、D. sp. 3及D. sp. 4；2種Diatrypella，為Dl. favacea及Dl. psidii；7種Eutypa，為E. capparidis、E. limiformis、E. sp. 1、E. sp. 2、E. sp. 3、E. sp. 4和E. sp. 5；11種Eutypella,為El. aulacostroma、“Peroneutypa” bellula、El. curvispora、El. gliricidiae、El. scoparia、El. sp. 1、El. sp. 2、El. sp. 3、El. sp. 4 、El. sp. 5及El. sp. 6。

The fungal family Diatrypaceae belongs to the class Pyrenomycetes of the phylum Ascomycota, featuring carbonaceous stromata, perithecial ascomata, and sausage-shaped ascospores. This study is to investigate the species diversity of Diatrypaceae in Taiwan. Identification of these fungi was carried out by using teleomorphic traits as well as cultural and anamorphic traits. Besides, ITS sequences were obtained to help reconfirm the identities of certain studied species. This study contains 30 species; 15 of these appear hitherto undescribed. Totally, 30 species are reported herein, including ten species of Diatrype—D. chlorosarca,D. enteroxantha,D. hypoxantha, D. microstroma, D. mindanaensis, D. cf. stigmaoides, D. sp. 1, D. sp. 2, D. sp. 3, and D. sp. 4; two of Diatrypella—Dl. favacea and Dl. psidii; seven of Eutypa—E. capparidis, E. limiformis, E. sp. 1, E. sp. 2, E. sp. 3, E. sp. 4, E. sp. 5; eleven of Eutypella—El. aulacostroma, “Peroneutypa” bellula, El. curvispora, El. gliricidiae, El. scoparia, El. sp. 1, El. sp. 2, El. sp. 3, El. sp. 4, El. sp. 5, and El. sp. 6.
