Old Puffballs
This photo was taken at the Reader Rock Garden yesterday, 6 May 2015, when I called in after a volunteer shift. Despite the fact that they are old ones from last year, it still felt good to finally see some kind of fungus.
"A puffball is a member of any of several groups of fungi in the division Basidiomycota. The puffballs were previously treated as a taxonomic group called the Gasteromycetes or Gasteromycetidae, but they are now known to be a polyphyletic assemblage. The distinguishing feature of all puffballs is that they do not have an open cap with spore-bearing gills. Instead, spores are produced internally, in a spheroidal fruitbody called a gasterothecium (gasteroid ('stomach-like') basidiocarp). As the spores mature, they form a mass called a gleba in the centre of the fruitbody that is often of a distinctive color and texture. The basidiocarp remains closed until after the spores have been released from the basidia. Eventually, it develops an aperture, or dries, becomes brittle, and splits, and the spores escape. The spores of puffballs are statismospores rather than ballistospores, meaning they are not actively shot off the basidium. The fungi are called puffballs because clouds of brown dust-like spores are emitted when the mature fruitbody bursts, or in response to impacts such as those of falling raindrops." From Wikipedia.
