Earth Ball Mushroom
Scleroderma citrinum

Field Notes
Description:
Some authors call the mushrooms in Scleroderma "earthballs," to emphasize their differences from fleshier puffballs. Many Scleroderma species have tough outer rinds, and Scleroderma citrinum has a rind that is scaly and hard. 2-10 cm across; round or flattened; the surface hard and scaly, yellowish to yellow-brown, often cracked; the "skin" whitish when sliced but blushing pinkish; sometimes gathered at the base, where mycelial strands may be found.
Habitat:
Mycorrhizal with hardwoods and conifers; often found in mossy areas (occasionally on well-rotted wood); growing alone, scattered, or gregariously; widely distributed; summer and fall.
Notes:
Scleroderma citrinum is the only mushroom that plays host to Boletus parasiticus, an extremely odd little bolete that actually parasitizes this puffball. This one is an old specimen.
