This is the third annual Week of the Fungi on Small Things Considered, a sporadic undertaking (please excuse the pun).
"Sooner or later, but usually sooner, anyone dealing with fungi will have to deal with the issue of spore dispersal. Many fungi, mushrooms included, are a spore’s way of spreading spores through the environment. They do this in varied and universally ingenious ways. Spores, like mammalian sperm, are made in excess, which enhances the chances of some “making it.” Anybody who has made the spore print from a mushroom can attest to the large number of spores produced. This is true not only for the Basidiomycetes, to which most mushrooms belong, but also for the larger Ascomycetes, (the group that includes not only yeast but also most molds, as well as larger organisms such as the cup fungi)."
