Agaricus dulcidulus is a small sized mushroom belonging to the Agaricales order, family Agaricaceae, growing in deciduous woodlands of Europe, but also recorded in North America, North Africa and Asia. The English name is rosy wood mushroom. Despite the tendency of some sources to synonymize it with Agaricus semotus, this is a distinct taxon.
Description[edit | hide all | hide | edit source]
Cap 2 to 7 cm, convex-rounded often with inflexed margins at first, then flattens when aging, covered in purple-brown to pinkish dense fibriles that fade in colours towards light grayish-pink from the centre towards margins.
The gills are free from attachment to the stipe, dense, starting pale gray-brownish when young, then turning dark purple-brown with age, with a lighter crenulated edge. The stipe is cylindrical, 2–5 cm long and 0.4–0.8 cm broad, bulbous or clavated at the base, withish, slightly darkening toward the base in yellow-brownish tints. The ring, remnant of the veil present in young fructifications, is whitish, descendent, thin and fragile. The odor and taste resembles almonds.
The spore print is dark brownish. The spores are 4.5–6.0 x 3.5–4.0 µm on average, nonamyloid, and elliptical. The flesh turns slightly in yellow when cut or bruised, sometime with orange tints in stipe.

Edibility[edit | hide | edit source]
Although considered to be edible, the small size and usually the sporadic presence prevents it from being widely eaten.
