Sandy Geopora (Geopora arenosa)


The fruiting body is 1-2 centimeters, sometimes up to three centimeters in diameter, develops as a semi-underground, spherical, then an irregularly shaped hole forms in the upper part and, finally, when ripe, the ball breaks with 3-8 triangular lobes, acquiring a cup-shaped or saucer-shaped shape. Hymenium (inner spore-bearing side) from light gray, whitish-yellow, to ocher, smooth. The outer surface and edges are yellowish-brown, brown, with short, wavy, brown hairs, with grains of sand adhering to them. The hairs are thick-walled, with bridges, sometimes branched at the ends.

The flesh is whitish, rather thick and fragile. No special taste or smell.

Spores are ellipsoidal, smooth, colorless, with 1-2 drops of oil, 10.5-1219.5-21 microns. 8-spore bags. The spores are arranged in one row in the bag.


It is considered a rather rare mushroom. It grows singly or in clusters on sandy soil and in areas after fires, on gravel-sand paths of old parks (in Crimea), on fallen needles. Growth occurs mainly in January-February, with cold, long winters, fruit bodies come to the surface in April-May (Crimea).


Sandy geopore is considered an inedible mushroom. No data on toxicity.

Similar types and differences from them

It looks like a larger pine Geopora, in which the spores are also larger. The sandy geopore may be similar to Petsitsa changeable, which also likes to grow in areas after fires, but the size of the geopore will not allow it to be confused with a much larger petsitsa.
