“…List of Caecomyces species. The following Caecomyces species have been proposed: C. communis [54], C. equi [43], C. sympodialis [102] and C. churrovis [40]. Caecomyces communis [54] and Caecomyces equi [43] were initially distinguished by Gold et al [43] based on the presence of single bulbous rhizoid in C. equi as opposed to multiple bulbous rhizoids in C. communis .…”

“…Diagnosis. Detailed description is provided in [102]. In addition to the general characteristics of the genus Caecomyces , the species is unique in producing thalli with multiple sporangia (more than three) that are sympodially distributed on long and tubular unbranched sporangiophores (Figs i–k in [102]).…”

“…Descriptions of C. sympodialis in [102] and C. churrovis in [40] demonstrate their bulbous rhizoidal nature. Phylogenetically, C. sympodialis is distinct from C. communis (3.62% divergence at the ITS1 level), and C. churrovis (4.25% divergence at the ITS1 level) ().…”

“…Occurrence. Isolates of Caecomyces have been reported from horse (Equus ferus) faeces [43,54], cow rumen [13,43,102] and faeces [87], Sheep salvia [94], rumen [103] and faeces [40,94], fallow deer (Dama dama) faeces [28], Yak rumen and faeces [64], rumen and faeces of water buffalo [104], goat rumen [66], and alpine ibex faeces [98]. Culture-independent diversity surveys suggest the ubiquity of members of the genus Caecomyces in a wide range of foregut and hindgut animals [28], although rarely representing the most dominant member of the community [31], although a recent study has identified Caecomyces as the most abundant genus in faecal samples from donkeys [105]).…”

Members of the anaerobic gut fungi (Neocallimastigomycota) reside in the rumen and alimentary tract of larger mammalian and some reptilian, marsupial and avian herbivores. The recent decade has witnessed a significant expansion in the number of described Neocallimastigomycota genera and species. However, the difficulties associated with the isolation and maintenance of Neocallimastigomycota strains has greatly complicated comparative studies to resolve inter- and intra-genus relationships. Here, we provide an updated outline of Neocallimastigomycota taxonomy. We critically evaluate various morphological, microscopic and phylogenetic traits previously and currently utilized in Neocallimastigomycota taxonomy, and provide an updated key for quick characterization of all genera. We then synthesize data from taxa description manuscripts, prior comparative efforts and molecular sequence data to present an updated list of Neocallimastigomycota genera and species, with an emphasis on resolving relationships and identifying synonymy between recent and historic strains. We supplement data from published manuscripts with information and illustrations from strains in the authors’ collections. Twenty genera and 36 species are recognized, but the status of 10 species in the genera Caecomyces, Piromyces, Anaeromyces and Cyllamyces remains uncertain due to the unavailability of culture and conferre (cf.) strains, lack of sequence data, and/or inadequacy of available microscopic and phenotypic data. Six cases of synonymy are identified in the genera Neocallimastix and Caecomyces, and two names in the genus Piromyces are rejected based on apparent misclassification.

Biodiversity of Anaerobic Fungi from Ruminants in Republic of Macedonia

Anaerobic chytridiomycete fungi are found in the gastrointestinal tracts of sheep, cattle and goats, as well as in many other domesticated ruminant and nonruminant herbivores and a wide variety of wild herbivorous mammals. They are principally found associated with the fibrous plant particles of digesta and as free swimming zoospores in the fluid phase. The presence of large fungal populations in animals consuming mature pasture or diets largely composed of hay or straw together with the production of highly active fibre degrading enzymes lead to the belief that anaerobic fungi may have a significant role to play in the assimilation of fibrous feeds by ruminants. This paper is focused on anaerobic fungi because of their unusual biology and metabolism, and the biotechnological potential of their cellulases.

beta-D-Glucosidase, beta-D-fucosidase, beta-D-xylosidase, and beta-D-cellobiopyranosidase activities in Caecomyces communis, Neocallimastix frontalis, and Piromyces rhizinflata, located with fluorescent conjugates, occur throughout the whole thallus as from zoospore germination and disappear before sporulation. beta-D-Galactosidase and alpha-L-arabinopyranosidase activities are low or nonexistent. A xylanase, detected by indirect immunofluorescence, was observed at the surface of the vegetative cells, vesicles, or rhizoids. Cross-reactions prove the existence of analogies in structure among the enzymes of these anaerobic gut fungi.
