Sexual reproduction leads to the development of haploid spores, termed
Ascospores
Ascospores are produced in a sac-like structure called
Ascus
contains numerous asci
Ascocarps or ascomata
leads to conidiation from a generative conidiogenous cell
Asexual reproduction
Three medically important subphylum:
Taphrinomycotina, Saccharomycotina, Pezizomycotina
contains the genus Pneumocystis, formerly classified under the kingdom Protozoa.
Taphrinomycotina
contains the class Saccharomycetes belongs to order

Saccharomycotina
contains two classes: Eurotiomycetes and the Sordariomycetes
Pezizomycotina
Characterized by vegetative yeast cells which proliferate by budding or fission.
