今天，真菌以极大的多样性出现在植物的几乎每一个部分，活的和死的。科达期裸子植物是晚古生代古热带植物区系的重要组成部分。然而，与这些植物的茎相关的真菌很少被记录。担子菌是现存真菌的主要类群之一，可能在古代大陆生态系统中发挥了重要作用，但在上古生界很少发现。山西省太原组上部（下二叠统）保存了一个含有大量分枝和有隔菌丝的石状化石Shanxioxylon sp.。这里描述的真菌遗骸是与来自华夏的二叠纪cordaitalean茎相关的真菌的第一个证据。他们与华夏cordaites扩大知识的生态和植物基质的担子菌真菌在二叠纪。
Fungi today occur in great diversity on virtually every plant part, living and dead. Cordaitalean gymnosperms were important components of floral element in the late Palaeozoic palaeotropical floras. However, fungi associated with the stems of these plants are rarely documented. Basidiomycetes are one of the major groups of extant fungi, and may have played an important role in ancient continental ecosystems, but are rarely discovered in the upper Palaeozoic. A stem of the fossil cordaite Shanxioxylon sp. containing abundant ramifying and septate hyphae with clamp connections is preserved in the upper Taiyuan Formation (Cisuralian, lower Permian) in Shanxi Province, North China. The fungal remains described here are the first evidence of fungi associated with Permian cordaitalean stems from Cathaysia. Their association with Cathaysian cordaites expands knowledge of the ecology and plant substrates of basidiomycetous fungi in the Permian.
