Stekherinum Murashkinsky (Metuloidea murashkinskyi) sary sy famaritana

This fungus was first described in 1931 by American mycologist Edward Angus Burt under the Latin name Hydnum murashkinskyi. It was assigned to the genus Hydnum because of its spiny hymenophore, and received the specific name in honor of the professor of the Siberian Agricultural Academy K.E. Murashkinsky, who in 1928 sent the samples he had collected to Bert for identification. Since then, this fungus has changed several generic names (having been in both the genus Steccherinum and the genus Irpex), until it was assigned to the newly formed genus Metuloidea in 2016.

vatana voankazo – semicircular sessile hats with a narrowed base, which can be open, reaching 6 cm in diameter and up to 1 cm thick. They are often arranged in tiled groups. They are leathery when fresh and become brittle when dry. The surface of the caps is initially pubescent, with a pronounced concentric striation. With age, it gradually becomes bare. Its color varies with age and humidity from whitish, yellowish and creamy to pinkish or reddish brown. In young fruiting bodies, the edge is often lighter.

Hymenophore hydnoid type, i.e., spiny. Spines are conical, up to 5 mm long (shorter closer to the edge of the cap), from beige-pinkish to reddish-brown, in young fruiting bodies with lighter tips, often located (4-6 pieces per mm). The edge of the hymenophore is sterile and of a lighter shade.

The fabric is 1-3 mm thick, whitish or yellowish, leathery-cork consistency, with a strong anise smell, which persists even in herbarium specimens.

The hyphal system is dimitic with thick-walled sclerified generative hyphae 5–7 µm thick. Spores are cylindrical, thin-walled, 3.3-4.7 x 1.7-2.4 µm.

Stekherinum Murashkinsky lives on dead hardwood, preferring oak (as well as birch and aspen) in the southern parts of its range, and willow in the northern parts. Causes white rot. The period of active growth is summer and autumn, in spring you can find overwintered and dried last year specimens. It occurs in fairly moist mixed or deciduous forests with a large amount of deadwood.

Recorded in the European part of Our Country, the Caucasus, Western Siberia and the Far East, as well as in Europe (at least in Slovakia), China and Korea. Meet infrequently. Listed in the Red Book of the Nizhny Novgorod region.
