Saccharomycotina is a subphylum of the phylum Ascomycota (fungi which form their sexual spores in sac-like asci), and consists of yeasts - they form no ascocarps (fruiting bodies), their asci are naked, and they can reproduce asexually by budding.[2]
^ ab See for instance the Systema Naturae 2000 classification or the O. E. Eriksson (2006) classification in Taxonomicon for the taxonomic tree. Other classification systems do not necessarily recognize the subphylum level, for instance Index Fungorum puts Saccharomycetes directly as a daughter of Ascomycota.
