Sterigmata a spore-bearing projection from a cell. It is found in some fungi.
An apiculus is the part of a fungal spore which attaches to the sterigmata at the end of a basidium.
The mushroom life cycle consists of spore germination, mycelium growth, fruiting body formation, spore dispersal, and spore germination again. Spores, released from the mature mushroom, germinate to form thread-like structures called mycelium. The mycelium grows, gathers nutrients, and eventually forms a mushroom fruiting body where new spores are produced for dispersal and continuation of the cycle.
