Russula albonigra |
Russula albonigra, is a large species with crowded gills. It is often mistakenly recorded as Russula nigricans, another blackening species but with thick, distant gills. This is an edible species, but it is of only moderate quality and not much sought after. You may also find this species recorded under the scientific name Russula anthracina. |
| Fruiting bodies of this large mushroom are slow to rot, and
they can be found standing or lying more or less intact on woodland floors
throughout the winter months and into early spring.
Several small agaric fungi parasitise aged fruiting bodies of the Russulaceae - notably Nyctalis asterophora, which is specific to Russula nigricans, and Nyctalis parasitica which also grown on Russula albonigra. |
Cap |
6 to 12 cm in diameter, convex with an inrolled margin and later slightly depressed, the caps are at first dirty-white, becoming brownish-black as the fruiting body matures. |
Gills |
Shortly decurrent and crowded, the gills are buff or straw-coloured at first, blackening at much the same rate as the cap blackens. |
Stipe |
15 to 30mm in diameter and 3 to 6 cm tall, the brittle stems are smooth and more or less cylindrical. The surface and the flesh of the cap blacken at much the same rate as the cap blackens. There is no stem ring. |
Spore print |
White. |
Odour/taste |
No distinctive odour; mildly bitter taste. |
Habitat |
Coniferous and broad-leaf woodland. |
Season |
August to October. |
Occurrence |
Infrequent. |
