Sarcodon Cyrneus

Sarcodon cyrneus, commonly referred to as the Cyrene Amethyst Deceiver, is a rare and visually striking tooth fungus known for its violet to purplish hues and spiny undersurface. Belonging to the Sarcodon genus, it is typically found in Mediterranean and subalpine forests, forming mycorrhizal relationships with coniferous trees. Although not widely consumed, its vivid coloration and rarity have attracted the attention of mycologists and mushroom enthusiasts.

History

Named after the island of Corsica (anciently known as Cyrne), S. cyrneus was first described in the 20th century and remains one of the lesser-known members of the Sarcodon genus. Its nickname as a “deceiver” is inspired by its color resemblance to Laccaria amethystina (Amethyst Deceiver), though the two are unrelated and structurally quite different.

While Sarcodon species are more common in temperate forests, S. cyrneus has a more restricted Mediterranean range. It is not traditionally used in medicine or cuisine but is valuable ecologically and taxonomically.

Overview

The cap is typically 5–12 cm wide, convex to depressed in shape, and displays shades of amethyst, violet, or grayish-lilac. The underside features soft, purplish spines instead of gills—typical of hydnoid fungi. It grows on soil, often under pine or fir trees, and fruits in late summer to autumn.

Although considered non-toxic, it is not commonly consumed due to its tough texture and bitter flavor. Its main significance lies in its role in forest ecosystems as a mycorrhizal partner, aiding in nutrient exchange between soil and trees.
