Saccharomycotina
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.
The only class in this subphylum is Saccharomycetes.
It includes the well-known Baker's Yeast Saccharomyces cerevisiae and the genus Candida which infects humans.
