中国星裂衣属二新记录种

Two Newly Recorded Species of Astrochapsa from China

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30~75μm×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55~90μm×22~28μm,含有斑点酸。

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 30–75μm×10–25μm,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(55–90μm×22–28μm),and presence of stictic acid.
