Gumaria hemispherical (Humaria hemisphaerica)

Before us is a small cupped mushroom, which, fortunately, is easily identifiable among many similar small 'cups' and 'saucers'. Gumaria hemispherical rarely grows more than three centimeters wide. It has a whitish, grayish or (less often) pale bluish inner surface and brown outer. Outside, the mushroom is entirely covered with tough brown hairs. Most of the other small cupped mushrooms are either brightly colored ('Elf's Bowl') or smaller (Gnarled Dumontinia), or grow in very specific places, such as old fireplaces.

Description

The fruiting body forms a closed, hollow ball, then bursts from above. In youth it looks like a goblet, with age it becomes wider, cupped, saucer-shaped, reaches a width of 2-3 centimeters. The edge is turned inward in young mushrooms, later, in old ones, it is turned outward. The inner side of the fruit body is dull, light, often wrinkled at the 'bottom', in appearance it is somewhat reminiscent of semolina. With age it becomes brownish. The outer side is brown, densely covered with brown fine hairs about one and a half millimeters long.

Leg: absent. Smell: not distinguishable. Taste: no data available. Flesh: light, brownish, rather thin, dense.

Microscopy: Spores are colorless, warty, elliptical, with two large drops of oil, which disintegrate upon reaching maturity, measuring 20-25 10-14 microns. Asci are eight-spore. Paraphysis filamentous, with bridges.

Season and distribution

Gumaria hemispherical is widespread throughout the world, grows on moist soil and, less often, on well-rotted wood (presumably deciduous). It occurs not often, not annually, singly or in groups in deciduous, mixed and coniferous forests, in thickets of bushes. Fruiting time: summer-autumn (July-September).

Edibility

Some sources categorically classify the mushroom as inedible. Some write evasively that the mushroom has no nutritional value due to its small size and thin flesh. No data on toxicity.

Similar types and differences from them

Despite the fact that Gumaria hemispherical is considered a fairly easily recognizable fungus, there are several species that are considered similar in appearance. Geopixis coal (Geopyxis carbonaria): it is distinguished by ocher color, whitish teeth on the upper edge, lack of pubescence and the presence of a short stem. Hemispherical trichofea (Trichophaea hemisphaerioides): it is smaller (up to one and a half centimeters), more extended, saucer-shaped, not cupped, in shape and lighter in color.

Notes: The list of synonyms is huge. In addition to those listed, some sources indicate a synonym for Humaria hemispherica, just like that, without the 'a', this is not a typo.
