Abstract
Agaricomycetes are major components of extant terrestrial ecosystems; however, their fruiting bodies are exceedingly rare as fossils. Reinvestigation of a peculiar fossil from Late Triassic sediments of southern Germany interpreted as a bracket fungus revealed that this fossil in fact represents a wood abnormality, resulting from injury to the cambium and subsequent callus growth in a Baieroxylon -like ginkgoalean wood. As a result, the fossil record of the Agaricomycetes does not yet pre-date the Early Cretaceous, suggesting a late diversification of basidiomycetes possessing large fruiting bodies.

前白垩纪真菌尚未被发现:对德国南部三叠纪支架真菌的重新调查
菌丝菌是现存陆地生态系统的主要组成部分;然而，它们的子实体作为化石极为罕见。对德国南部晚三叠世沉积物中一个被解释为支架真菌的奇特化石的重新研究表明，这个化石实际上代表了木材的异常，这是由于Baieroxylon样银杏木材的形成层损伤和随后的愈伤组织生长造成的。因此，担子菌的化石记录并不早于早白垩纪，这表明担子菌的多样化较晚，具有较大的子实体。(©2012 WILEY-VCH Verlag GmbH &KGaA公司，Weinheim)
