Stropharia aeruginosa

Stropharia aeruginosa (Echte kopergroenzwam (BE) / Verdigris agaric (EN) / Grünspan-Träuschling (DE) / Strophaire vert-de-gris (FR)) is a species of fungus in the Strophariaceae family.

When young and fresh, Stropharia aeruginosa is stunning and unmistakable: its broadly bell-shaped cap is deep blue to deep green, and so slimy that it glistens on the forest floor. The young stem is also blue or green, and decorated with white scales. As it ages, however, this species begins to develop yellowish colors, and is eventually a nondescript brownish yellow overall. The species has a partial veil that sometimes leaves white remnants on the cap margin and an ephemeral ring or ring zone on the stem. This is the main feature which distinguish this species from the species I showed yesterday: The look-a-like Stropharia caerulea does not devellop this ring or ring zone.
Stropharia aeruginosa is deemed poisonous by some authorities, although effects are little known and its toxic constituents undescribed.

Wow, das ist ein herrliches Foto. Dieser Pilz ist sogar eßbar, obwohl er so giftig ausschaut.
