features

Macroscopic features

The 1–5 cm wide hat is light or dark olive brown and often shows yellowish tones. Older fruit bodies are often predominantly yellowish, as they lose the top, brownish layer due to the weather. Young specimens have a characteristic hump. The lamellas run down the stem for a short time and are initially white, but then turn yellow. They stand apart and are plump. The stem is often tapered towards the base. It is yellowish, sometimes orange-red in color and has a layer of mucus of varying thickness. In the upper part of the young specimens, a slimy ring zone is indicated, above there is no mucus. The flesh is soft and yellowish. It can smell slightly fruity or sweet and has a mild taste. The spore powder is white and cannot be stained with iodine solution .

Microscopic features

The spores measure 7-9 x 4-5 micrometers.

Species delimitation

The frost snail is one of the few mushrooms that fructify late in the year after the first night frosts . Because of this, and because of the yellowish colors, there is little risk of confusion with other species. The larch snail ( H. lucorum ) including the speciosus variety and the lively orange-capped variety aureus have a certain similarity . But they live with larches and predominantly settle in mountainous areas.

Ecology and phenology

It can only be found in the root area of pine trees . It only develops relatively small fruit bodies . But since it often occurs in large numbers, it can be collected richly. The fruiting bodies are found from October to December.

meaning

The frost snail is a popular edible mushroom with a strong aroma.
