Document Summary

Auprobasidium pullalans (ascomyce) if you grow under favorable conditions it is filamentous, that"s why it is not truly a yeast. Under nonfavorable conditions shorten bits of hyphae, buds off, modified short filaments on filoplane, more like budding. Sporobolomyces roseus (bacidiomyce) when conditions are favorable: lots of budding, increases population very rapidly. When conditions are not favorable = ballistospores (wind dispersed) also produces chlamydospores (when you take a cell in the middle of hyphae thickens cell wall, separates asexual production) Chlamydospores, produced when conditions are very unfavorable. contain a lot of melanin, helps in terms of preventing desiccation, thickens wall helps retain water, prevent chlamydospore from becoming food for other organisms. Any time a piece of hyphae is converted into a thicken cell. Grow as normal filaments in culture in laboratory. In phyloplane, the canidia lands of phylaplane, produces a short piece of hyphae, on tip produces more canidia. Produces a little bit of hyphe to produce more canidia, limits hyphae.
