Anaeromyces Breton et al.
The genus Anaeromyces was described using morphological characteristics by Breton et al. (1991). Following isolation of Anaeromyces mucronatus from the rumen of a cow. The type culture, Anaeromyces mucronatus (NR_111156.1) was obtained from faeces of an American bison by Fliegerova et al. (2004). This group isolated a number of different polycentric fungi belonging to the genera Orpinomyces and Anaeromyces. These two genera are morphologically very similar, but Fliegerová et al. (2004) used molecular methods (analysis of ITS1 fragments) in addition to morphology to distinguish between them. From a descriptive perspective, the genus Anaeromyces contains species of strictly anaerobic fungi, which are characterized by a polycentric thallus, a polynuclear rhizomycelium of extensively branched hyphae, zoosporangia that are sometimes mucronate with an acuminate apex and uniflagellated zoospores. The rhizomycelium contains hyphae that can be tubular and uniform or very wide, sometimes with constrictions. Sporangia can develop intercalary as swellings in hypha or on sporangiophores. Some cultures fail to produce mature sporangia and zoospores are rarely seen making classification by molecular means the only sure way of assigning them to the genus.
