The lichenised fungal genus is a very common crustose lichen element in tropical to subtropical forests, but little research has been done on this genus in China. During our study on in China, based on morphological characteristics, chemical traits and molecular phylogenetic analysis (ITS and nuLSU), three new 3-septate species with red or orange oil in over-mature ascospores were found: , and Compared to the known 3-septate species of with red or orange oil, is characterised by the inspersed hamathecium; is characterised by the IKI+ red hamathecium and the existence of an unknown lichen substance; and is characterised by the absence of endospore layers in the spore tips and the absence of pseudocyphellae. It is reported for the first time that the presence of a gelatinous halo around the ascospores of is common. A word key for the species with red or orange oil in over-mature ascospores is provided.
地衣化真菌属是热带至亚热带森林中一种非常常见的壳状地衣类群，但在中国对该属的研究较少。在我们对中国该属的研究过程中，基于形态特征、化学特性以及分子系统发育分析（ITS和nuLSU），发现了三个新的具三隔膜的物种，其成熟的子囊孢子中含有红色或橙色油滴：[物种名1]、[物种名2]和[物种名3]。与已知的具红色或橙色油滴的具三隔膜的[属名]物种相比，[物种名1]的特征是具散生的侧丝；[物种名2]的特征是碘液反应呈红色的侧丝以及存在一种未知的地衣物质；[物种名3]的特征是孢子顶端没有内孢子层且没有假杯点。首次报道[物种名]的子囊孢子周围存在胶状晕圈是常见现象。提供了一个针对具成熟时红色或橙色油滴的[属名]物种的检索表。
