Marasmius wynneae

Species found in beech forests on calcareous soil, with a convex to flattened pileus up to 5 cm across, beige-grey, light brown at the centre, greyish lamellae with slight violaceous tints, a stipe cream-coloured in the upper part and reddish at the base, an odour of bitter almonds, and an insipid taste.

Hymeniform cuticle (pileipellis), with clavate to pyriform, thick-walled hyphae measuring 16–27 µm long by 6–15 µm wide, with very faint brown intracellular pigment.

Sterile cells of the lamellar edge (cheilocystidia) very irregular, cylindrical, flexuous, with swellings and occasional bifurcations, thick-walled, measuring 25–55 µm long by 5–14 µm wide.

Basidia cylindrical-clavate, 30–35 µm long, quite narrow (only 4–5 µm wide), with basal clamps, 4-spored.

Spores ellipsoidal, with a pointed end where the apiculus is located, smooth, hyaline, thin-walled, measuring 6.5–8.5 µm long by 3–4 µm wide, with one or several oil or lipid droplets inside.
