Description

Cap: Its cap grows only to 6-8 cm wide. Initially conical, but then flattens more and more, with a small, blunt umbo always remaining in the center. Its color is silvery-grayish-brown, turning lemon yellow over time. Its spotted surface is covered with radial fibers or fine scales.

Gills: Its white gills are densely standing, turning yellow in older mushrooms. They are curved-adnate to the stem, and when young, the gills are covered with a cobweb-like veil, which disappears without a trace over time.

Stem: The almost white stem is only 6-8 cm tall, its surface is silky fibrous.

Flesh: White and weakly floury-smelling.

Spore: White; 5-6 x 3-3.5 µm; elliptical, smooth.

Occurrence: Common species in Hungary. Found in acidic and slightly acidic hornbeam-oak forests, sandy poplar forests, mixed forests from May to November.

Edibility: Edible mushroom species.

Confusion: The edible grey tricholoma is quite similar, but it is found only under two-needle pines and its gills are also gray. It can be confused with the black-edged parasol growing on calcareous soil, but that is not dangerous either.

Note: Its mild floury smell stands out, but this is true for several mushroom species. Therefore, it cannot be used as a sole identifying feature. It is better to pay attention to the yellowing. There are about 18 similar, gray or grayish-brown, fibrous-scaly parasol species. Some of them are poisonous, such as the tiger tricholoma. scalpturatum means felted, scaly cap surface.

Species description: In 1779, the French mycologist Pierre Bulliard described this species as Agaricus argyraceus. His compatriot Claude Casimir Gillet gave it its current name in 1874.
