Agaricus bresadolanus

Agaricus bresadolanus is a species of fungus in the genus Agaricus. Its spores are ellipsoid and lack a germ pore, with dimensions of 5.5–7.5 by 4.0–5.0 μm.
It was described by Hungarian mycologist Gábor Bohus in 1969. A rare species, it has been recorded in Asia and southern Europe, where it fruits singly or in groups along paths and in grassy area of deciduous woodland.

Toxicity

While generally considered edible, a small number of reports of severe stomach pain after ingestion suggest that it might be somewhat poisonous.
