Hygrophorus agathosmus is a species of fungus belonging to the family Hygrophoraceae. It is commonly known as the almond-scented waxcap, due to its distinctive sweet almond aroma. This mushroom is found in various parts of the world, particularly in temperate forests, where it forms mycorrhizal associations with certain types of trees, especially conifers.

Description

Hygrophorus agathosmus features a cap that ranges from 5 to 10 cm in diameter, initially convex before flattening out with age, often with a slight central depression. The cap surface is smooth and slimy, with a color that varies from white to pale grey or pinkish. The gills are decurrent, meaning they extend down the stem, and are spaced closely together. They are white or slightly pinkish in color.

The stem of the mushroom is 4 to 10 cm tall and 1 to 2 cm thick, cylindrical, and often narrows towards the base. It is white, smooth, and can also be slimy, especially towards the top near the gills. The flesh of the mushroom is white, with a notable almond scent, particularly when fresh.

Habitat and Distribution

Hygrophorus agathosmus is primarily found in temperate regions, with a preference for coniferous forests. It forms symbiotic mycorrhizal relationships with the roots of living trees, which is essential for the nutrient exchange between the fungus and its host. This species is widely distributed in North America, Europe, and parts of Asia.

Edibility

The almond-scented waxcap is considered edible, with its sweet almond aroma contributing to its desirability. However, as with all wild mushrooms, caution is advised when foraging, as it can be confused with other less palatable or toxic species.

Conservation

While not currently listed as endangered, the habitat of Hygrophorus agathosmus, like that of many forest-dwelling species, is threatened by deforestation, pollution, and climate change. Efforts to conserve its natural habitat are crucial for the survival of this species.
