Disciotis venosa

Distribution: Veinous saucer is common in the temperate zone of the Northern Hemisphere. Quite rare. Appears in spring, along with morels, from mid-May to early June. It is found in coniferous, mixed and deciduous (more often oak and beech) forests, including floodplain, on sandy and clay soils, in humid places. Occurs singly and in small groups. Often grows together with semi-free morel (Morchella semilibera), often associated with butterbur (Petasites sp.). Probably, it is a saprotroph, but due to the relationship with morels, it is possible at least an optional mycorrhizal fungus.

Description: The fruiting body is apothecia with a diameter of 3 – 10 (up to 21) cm, with a very short thick 'stem'. In young mushrooms, the 'cap' has a spherical shape with edges curving inward, then becomes saucer-shaped or cupped, and finally prostrate with a winding, torn edge. The upper (inner) surface – hymenophore – at first smooth, later becomes tuberous, wrinkled or veined, especially closer to the middle; color varies from yellowish brown to dark brown. The lower (outer) surface is lighter colored – from whitish to grayish-pinkish or brownish, – mealy, often covered with brownish scales.

The 'stem' is strongly reduced – short, thick, 0.2 – 1 (up to 1.5) cm long, whitish, often immersed in the substrate. The pulp of the fruiting body is fragile, grayish or brownish, with a characteristic chlorine smell, which, however, disappears during heat treatment. Spore powder is white or creamy. Spores 19 – 25 × 12 – 15 μm, smooth, broadly ellipsoid, without fat droplets.

Similarity: Due to the characteristic smell of bleach, Vein Saucer is difficult to confuse with other mushrooms, for example, with representatives of the genus Pecica. The largest, mature, dark-colored specimens are slightly similar to the common line.

Assessment: An intense bleach smell is characteristic, but it disappears during heat treatment. The venous saucer is edible, but tasteless.
