Oll's glass

Fruit body:

in a young fungus, the fruit body has an ovoid or spherical shape, then, as the mushroom matures, the fruit body becomes broadly bell-shaped or cone-shaped. The width of the fruiting body is from 0.5 to 1.3 centimeters, the height is 0.5 to 1.5 cm. The edges of the body are bent. At first, the fruit body resembles a wide, rounded cone or bell with flexible dense walls slightly tapering towards the base. The surface of the fruiting body is velvety, covered with fine hairs. In young mushrooms, the opening is covered by a creamy or beige-brown membranous membrane. As it matures, the membrane collapses and falls off.


on the outside, the peridium is smooth, dark brown, lead-gray to almost black. On the inside, the sides may be slightly wavy. Attached to the inner shell of the peridium are periodioli, which contain ripening spores.


up to 0.2 centimeters in diameter, angular, whitish when dry, enclosed in a transparent shell. Attached to the inner surface of the peridium with a mycelial cord.

Spores: smooth, transparent, elliptical.


Oll's goblet is found on grassy and woody remains or on soil in steppes, plantings, forests, meadows and pastures. Fruiting from May to October. It grows in close-knit or scattered groups mainly on decaying wood and the soil around it. Occasionally found in winter. A fairly common species, often found in greenhouses.


in food, this mushroom is not used.


bears a resemblance to the Dung Cup, which is distinguished by a conical narrow body and a shaggy-hairy outer surface of the peridium, black periodioli, larger spores and a darker inner surface of the fruiting body.


the young fruiting bodies of Oll's goblet resemble a ball or nest in shape. Then the fruiting bodies acquire a goblet or bell-shaped shape. A distinctive feature of the fungus is the presence of a single-layer membranous membrane that hides the opening and the serrated edge. Inside the hole, periodioli ripen - lenticular rounded parts of the gleb, which are attached to the shell with a mycelial cord. In a mature mushroom, the membrane ruptures and falls off.
