Morphological characteristics and phylogenetic analyses based on ITS and nLSU sequences reveal two new species of Sebacinaceae from southwest China, viz. and The two species have similar micromorphology characterized by clampless hyphae, hyphidia with simple septa, longitudinally septate, 4-celled, ovoid to subglobose basidia, and broadly ellipsoid to ovoid basidiospores. However, is characterized by cartilaginous to gelatinous, white to cream, sometimes semi-transparent basidiomata; basidiospores measuring 8.6-9.9 × 5.8-7.6 μm; and growth on dead ferns. is characterized by coriaceous, white-to-cream basidiomata; basidiospores measuring 10.2-12.9 × 6.3-8.7 μm; and growth on needles and bark of . The two new species are described and illustrated in this study.
基于ITS和nLSU序列的形态特征及系统发育分析揭示了来自中国西南部的两种新的红菇科真菌，即 和 。这两个物种具有相似的微观形态，其特征为无锁状联合菌丝、具简单隔膜的侧丝、纵向隔膜、4细胞、卵形至近球形的担子以及宽椭圆形至卵形的担孢子。然而， 的特征为肉质至凝胶状、白色至奶油色、有时半透明的担子果；担孢子大小为8.6 - 9.9×5.8 - 7.6μm；生长在枯死的蕨类植物上。 的特征为革质、白色至奶油色的担子果；担孢子大小为10.2 - 12.9×6.3 - 8.7μm；生长在 的针叶和树皮上。本研究对这两个新物种进行了描述和图示。
