This mushroom has basidia with four basidiospores and a tetrapolar mating
system. Its hyphae have clamp connections and most members of the genus, excepting a small minority, have a
monomitic hyphal system.the vegetative stage and the reproductive growth
stage. Generally, some kinds of stimuli are needed for the shift from mycelial (vegetative) growth to the fruitbody
formation (reproduction) phase. These stimuli include abrupt changes in temperature, humidity, gas concentration,
light and nutrient reserves, and physical stimuli. Among them, a sharp temperature drop is the most effective in
fruiting induction for most mushrooms. Fruiting is induced by low temperatures ranging from 10 to 15 in P.
ostreatus and P. eryngii. However, the fruiting of P. florida, P. sajor-caju, P. cornucopiae and P. cystidiosus is less
affected by temperature.
