I'm an amateur mycologist but maybe I can help you.
1. The spores are released when they are mature. The releasing "mecanic"
depend upon the mushroom group (ascomycetes, gasteromycetes,...). One good
exemple is the puff ball (Lycoperdon, Calvatia,...).
2. The spores are characterised by their color (spore print), their reaction
to some chemical (Melzer's solution,...), their length and width (in
micron), their shape and the ornementations on the spores.
Unfortunately, there's no standarized vocabulary to describe the forms of
the spores. A spore globulose for an author is spherical for another.
Look at the pictures in mycological guides; they illustrate well the form
and ornementation of differents types of spores.
You must know that mushroom's spores are not arranged in official groups
like the mushrooms (order, family, genus,...). The same spore form can
occurs in two or three differents genus. Spore form is just one in many
features we must look at to identify a mushroom specie.
