来自威斯康星州奥陶纪（约4.6亿年）的真菌菌丝和孢子化石与现代丛枝菌根真菌（球囊霉目，接合菌纲）非常相似。这些化石表明，球囊霉类真菌存在于陆地植物群最有可能仅由植物组成的时期，即白垩纪水平。因此，这些真菌可能在促进植物在陆地上的定居方面发挥了至关重要的作用，化石支持了真菌进化的分子估计，将陆地真菌的主要类群（子囊菌门，担子菌门和球囊菌门）的起源放在大约6亿年前。
Fossilized fungal hyphae and spores from the Ordovician of Wisconsin (with an age of about 460 million years) strongly resemble modern arbuscular mycorrhizal fungi (Glomales, Zygomycetes), These fossils indicate that Glomales-like fungi were present at a time when the Land flora most likely only consisted of plants; on,the bryophytic Level. Thus, these fungi may have played a crucial role in facilitating the colonization of Land by plants, and the fossils support molecular estimates of fungal phylogeny that place the origin of the major groups of terrestrial fungi (Ascomycota, Basidiomycota, and Glomales) around 600 million years ago.
