Fungus on liberty caps

Description:

small growths (about 1mm tall?) on dry(ish) P. semilanceata. The mushrooms, picked in the beginning of Oct 2012 were mostly dried and then left cramped in a small, air-tight container. They've spent perhaps 2 months in the container in this condition. Once opened, touching the decaying mushrooms released a cloud of spores(?). The whole thing smells like hay. Pic 1 shows what I think are the sporing bodies, pic 2 shows some cobweb-like growths (maybe mycelium?). Pic 3 shows how tightly packed the mushrooms were
