Romagnesi dung (Coprinopsis romagnesiana)

The Romanesi dung beetle can be called a kind of analogue of the well-known gray dung beetle, only with more pronounced scaly. The gray dung beetle has a gray cap with several tiny scales in the center, and the Romagnesi dung beetle is noticeably decorated with brown or orange-brown scales. Like other dung beetles, the plates of the Romagnesi dung beetle turn black as they age and eventually liquefy, creating an inky slime.


Ecology: Saprophyte growing in clusters on tree stumps or rotting roots around tree stumps. Occurs in spring and summer, there is evidence that two periods of fruiting are possible: April-May and again in October-November, possibly growing in summer in cool weather or in cool regions.

Cap: 3-6 cm in diameter, in young mushrooms of regular oval or ovoid shape, expands with maturity, acquiring a bell-shaped or broadly convex shape. Light, whitish to beige, densely covered with adjacent scales of brown, brown, orange-brown color. As the scales grow, the scales diverge slightly, remaining denser in the central part of the cap.

Plates: Adherent or loose, rather frequent, white in young mushrooms, with the onset of autolysis, acquire a purple-black color, eventually liquefy, turning into black 'ink'.

Leg: 6-10 cm in height, according to some sources up to 12 cm, and up to 1.5 cm thick. White, whitish, off-white, hollow in adult fungi, fibrous, fragile, slightly pubescent. May have a slight expansion downward.

Flesh: very thin in the cap (most of the cap are plates), white.

Smell and taste: indistinct.

Coprinopsis romagnesiana

Edible: The mushroom is considered edible (conditionally edible) at a young age, until the plates begin to turn black. Regarding the possible incompatibility with alcohol inherent in gray dung beetle: there is no reliable data.

Similar species: Gray dung beetle (Coprinus atramentarius) in appearance, but in general is similar to all dung beetles, ending their life path by turning into a slimy ink stain.
