Dry Air Spora

Spores function as reproductive units, as well as dispersal units of fungi. The majority of spores are adapted for airborne dispersal.  These spores become detached from the fungal source and are released into the air either passively or by active discharge mechanisms.   The mechanism of detachment is largely dependent upon the type of fungi the spores are from and the shape of the spores themselves.  One group of spores in particular, the dry air spora, is dispersed into the air passively by simple air movement.  These spores become detached easiest when wind speeds are high and humidity is low, or in other words, when the air is dry, hence the name dry air spora.  Once they are free from the fungal body, they will be deposited according to interacting variables such as wind current, thermal vectors, and topographical anomalies.
