Yeast is a fungus, so the yeast and fungal forms are the same, but there are different species. From Wikipedia:
"Among Candida species, C. albicans, which is a normal constituent of the human flora, a commensal of the skin and the gastrointestinal and genitourinary tracts, is responsible for the majority of Candida bloodstream infections (candidemia). Yet, there is an increasing incidence of infections caused by C. glabrata and C. rugosa, which could be because they are frequently less susceptible to the currently used azole antifungals.[17] Other medically important Candida species include C. parapsilosis, C. tropicalis, and C. dubliniensis.[7]
Other Candida species, such as C. oleophila have been used as biological control agents in fruit."
