摘要: 基于形态学、解剖学和化学特征,报道了2种星裂衣属(Astrochapsa)中国新记录种:假疱星裂衣(A.pseudophlyctis)和察氏星裂衣(A.zahlbruckner)。假疱星裂衣的主要识别特征是地衣体壳状,皮层较为致密,子囊盘圆形至不规则形,子囊孢子无色,砖壁型,大小为30~75 μm×10~25μm,未检测到次级代谢产物。察氏星裂衣的主要识别特征是地衣体壳状,子囊盘圆形至不规则形,盘缘凸起外翻且其内表面为白色,子囊孢子无色或浅棕色,砖壁型,大小55~90 μm×22~28μm,含有斑点酸。 |

Abstract: Two Astrochapsa species, A. pseudophlyctis and A. zahlbruckneri, are reported from China for the first time based on the morphological, anatomical and chemical characteristics. Astrochapsa pseudophlyctis is characterized by the crustose thallus with a compact surface, rounded to angular apothecia in outline, hyaline and muriform ascospores sized 30-75 μm×10-25 μm, and absence of lichen compounds detected. Astrochapsa zahlbruckneri is characterised by the crustose thallus, usually angular-rounded to irregular apothecia in outline with a strongly raised, jagged to typically lobed, upright to recurved margin, hyaline or slightly brownish and densely muriform ascospores (55-90 μm×22-28 μm), and presence of stictic acid. |
