The spotted larch grease or spotted yellow-foot ( Gomphidius maculatus ) is a species of fungus from the grease relatives family . It lives in symbiosis with larches and is mainly found in mountain forests.

features

Macroscopic features

The hat is 2–10 cm wide. The color is pale flesh yellow, flesh brown to wine brown and darkens with age. The hat often has black-brown spots. The surface is covered with a thick layer of mucus. Drops of this mucus can be an amber-like color. The lamellae are initially gray-white in color, but darken as the spores ripen until they have a gray-blackish color. They run down a stick . The spore powder is dark olive to black-brown. The stem is cylindrically shaped and slightly pointed at the lower end. It is dotted red-brown to black on a whitish background. The flesh is whitish, reddened on the cut surfaces and tinted chrome yellow in the base of the handle. The initially reddish bruises turn blackish-brown over time.

Microscopic features

The spores are spindle-shaped to long-elliptical and measure 19–23 × 6–7.5 micrometers. The club-shaped basidia with four sterigms are 48–60 micrometers long and 9–12 micrometers thick. The numerous cheilo- and pleurocystids are club-shaped to club-headed, hyaline to brown pigmented and measure 90–140 × 15–27 micrometers.

Species delimitation

The spotty larch smear is particularly similar to the gray-capped large smear ( G. glutinosus ), which only grows in spruce trees . While its white flesh does not discolour when injured, the trama of the spotty larch smear reddened when touched or on cut surfaces. The wine-brown or dainty larch grease ( G. gracilis ), on the other hand, does not redden, but Gerhardt suspects it to be identical to the spotty larch grease.

Ecology and phenology

The spotty larch smear is a mycorrhizal fungus that forms a close community with larches . It grows particularly in the mountains and is often found locally there.

The solitary to gregarious growing fruit bodies appear in late summer and autumn from around August to October.

distribution

The species is widespread in Europe, North America and Asia in the natural Larix area, but is also found in artificial plantings. It appears in colline to subalpine locations.

meaning

The spotty larch grease is edible .
