Classification: Fossil Chytridiomycota
Illmanomyces was established by Krings and Thomas (2014), with Illmanomyces corniger as the type species. It has been found in Rhynie chert and occurs on certain types of fungal spores. The genus Illmanomyces has a spheroid epibiotic sporangium with 4–5 discharge tubes, and an endobiotic rhizoidal system (Krings & Thomas 2014). Krings and Thomas (2014) concluded that I. corniger with Chytridiomycota has affinities based on rhizoidal and sporangial morphs. This genus has been found within loose accumulation of land plant and fungal spores and tissues, from early Devonian: Great Britain (Krings & Thomas 2014). No other species have been introduced to this genus, which remains monotypic.
Type species: Illmanomyces corniger M. Krings & T.N. Taylor
