Scientific name

The small, inedible lemon-yellow wooden cup or lemon-yellow brushwood cup ( Bisporella citrina , syn. Calycella citrina ) is a species of fungus from the Helotiaceae family. The small, plate-shaped and bright yellow fruiting bodies often grow in a grassy manner on debarked red beech wood.

features

Macroscopic features

The thick-fleshed and more or less sessile fruit bodies ( apothecia ) are initially flat, bowl-shaped and 1–3 mm wide. Because of their convex fruit slice, they are reminiscent of a small protruding nail head. The crowded, standing fruit bodies are usually bent into a bump and tend to grow together. The color is bright lemon or sulfur yellow in all parts. The blunt edge is bare, the smooth outside is usually a bit paler and the spore powder is white.

Microscopic features

The elongated-elliptical and slightly curved spores measure 8–13 µm × 3–4 µm. They are smooth, hyaline and, when ripe, are often constricted and septate. They usually contain tiny oil droplets on each end of the spore. The cylindrical, lobed tubes ( asci ) measure 80–140 × 5–6 µm. The filamentous paraphyses have yellow granulation and are slightly thickened at the tip.

Species delimitation

The lemon yellow wooden cup has a large number of similar relatives, which differ in their slightly different colors or locations. A reliable differentiation is usually only possible with a microscope. Because of its often grassy growth on debarked beech branches, the lemon-yellow wooden cup is relatively easy to see even without a microscope. The calyx-shaped stem cup ( Hymenoscyphus calycollus ), which also occurs on hardwood, is particularly similar , but has clearly stalked and larger fruiting bodies. Its spores are up to 20 µm long.

The sulfur- yellow core mushroom cup ( Bisporella sulfurina ) is even more similar . It grows on rotten hardwood branches such as maple, ash or linden that are colonized by heart mushrooms .

Ecology and diffusion

European countries with evidence of finding of the lemon yellow wooden cup.
Legend:
green = countries with found reports
cream white = countries without evidence
light gray = no data
dark gray = non-European countries.

The lemon yellow wooden cup is often found in large flocks on damp, dead branches of deciduous trees lying on the ground. It mainly grows on red beech wood. The fruiting bodies usually only appear in autumn.

The fungus is found almost worldwide. It has been found in North America (Canada, Mexico, USA), Central America (Costa Rica), South America (Chile), Asia (China, India, Japan, South Korea, Turkey), North Africa (Algeria, Morocco), Australia, New Zealand and Europe. The wooden cup is widespread in Europe and probably quite common everywhere.

meaning

Since the fruit bodies are only a few millimeters in size, the lemon yellow wooden cup is not an edible mushroom.
