Agaricus dulcidulus is a small
Description
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.[2]
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, whitish, 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
Macrochemical reactions: flesh turns orange and pileus turns yellow in contact with 10% KOH.
Other taxonomic considerations
Several characteristics like flesh yellowing on contact or in air, orange reaction with KOH, overall size, puts this species within Minores section of the genus Agaricus, along with Agaricus comtulus, Agaricus xantholepis, Agaricus porphyrizon and Agaricus luteomaculatus.
Habitat
Agaricus dulcidulus is a mycorrhizal species in close relation with different oak species.[3] The fungus prefers humid soil with rich decomposed leaves as a substrate. The basidiocarps appear, depending on microclimatic conditions, in late July to early October.
Edibility
Although considered to be edible, the small size and usually the sporadic presence prevents it from being widely eaten.
