在对保存于中国科学院微生物所菌物标本馆(HAMAsL)的鸡皮衣属地表进行研究过程中,发现一中国新记录种亚澳鸡皮表(Pertusaria thwaitesii)。该种地衣体灰白色至烟灰色,表面有皱褶,缝裂成网块状,无粉芽和裂芽;果疣半球形,顶部扁平,孔口较多,轻微下陷;子囊盘陷生于果疣妒:每个子囊含有2个袍子,孢子长椭圆形,孢子壁双层,端壁微加厚;皮层含有地衣黄,在波长365nm紫外光照射下呈现红褐色,髓层含有原岛衣酸。该种与海滨鸡皮衣(P.subobductans)和亚孔鸡皮衣(P.subpertusa)都含有2个长椭圆形的孢子,但是海滨鸡皮衣含有降斑点酸,皮层遏KOH由黄色变成红色;而亚孔鸡皮表含有富马原岛农酸,且孢子较大。亚澳鸡皮衣生长在海拔1200—2300m的阔叶树树皮上。
