Fruiting bodies described previously as sclerotia of Palaeosclerotium pusillum are cleistothecium-like, enclosed structures, containing spores within an ascus. The cleistothecia are composed of hyphae having dolipore-like septa and are attached to vegetative hyphae having clamp connections. The unique combination of ascomycete-like reproductive bodies and basidiomycete-like hyphae present in this Pennsylvanian fungus suggests that there already existed, during the Middle Pennsylvanian period, a group of fungi intermediate between the Ascomycetes and Basidiomycetes.
先前被描述为 Palaeosclerotium pusillum 菌核的子实体为闭囊壳状结构，内含子囊和孢子。闭囊壳由具桶孔隔膜的菌丝组成，与具锁状联合的营养菌丝相连。宾夕法尼亚纪真菌中存在子囊菌类生殖结构和担子菌类菌丝的独特组合，表明在中宾夕法尼亚纪时期已经存在一类处于子囊菌和担子菌之间的真菌。
