Scleroderma areolatum [ Basidiomycetes > Boletales > Sclerodermataceae > Scleroderma . . . ] by Michael Kuo This widely distributed Scleroderma species probably requires microscopic analysis for certain identification. Several similar species share most of its visible features: thin skin, small brownish scales over a yellowish background, a blackish interior, and a brownish to reddish reaction to KOH. A look at the spores of Scleroderma areolatum, however, eliminates the other possibilities. The spores are densely spiny but not reticulate, measuring 11-15 µ, with spines up to 2 µ long. Scleroderma lycoperdoides is a synonym. Description: Ecology: Mycorrhizal with hardwoods and conifers in moist, shady woods--but also possibly saprobic, since it is also found in open areas, gardens, and so on; growing gregariously or clustered (rarely alone); widely distributed in North America; summer and fall. Fruiting Body: 1-5 cm across; round or shaped like an inverted pear; the surface smooth and bruising reddish when young, becoming scaly (especially near the apex) and by maturity acquiring a "leopard skin" appearance with small brownish scales over a yellowish base color; skin 1 mm thick or less; without a stem, or occasionally with a poorly defined pseudo-stem; with white rhizomorphs attached to the base; odor sweetish or not distinctive. Spore Mass: Whitish and fleshy at first but soon dark purplish or olive brown, eventually powdery. Chemical Reactions: Surface instantly yellowish brown or dark red with KOH. Microscopic Features: Spores 11-15 µ; round or nearly so; densely spiny but not reticulate; with spines up to 2 µ long. REFERENCES: Ehrenberg, 1818.
