Extract from Wikipedia article: Peziza varia is a species of apothecial fungus belonging to the family Pezizaceae. This is a common European fungus associated with rotting wood. The ascocarps are cup-shaped and up to 6 cm (2.4 in) across. The inner surface is smooth and brown, the outer surface is pale, often almost white. This species is rather similar to some other members of the genus but can usually be distinguished by the distinctly layered flesh seen when a specimen is cut.
Peziza varia is a species of cup fungus that grows on soil, moss, and decaying organic matter. In St. Petersburg and Leningrad Oblast, it typically fruits from July to October, often in coniferous and mixed forests, as well as in urban parks and gardens. In north-western Russia, P. varia is widely distributed, commonly found in areas with rich soil and abundant vegetation, including the Karelian Isthmus and the Murmansk Oblast. The fungus produces small to medium-sized cups, 2-6 cm in diameter, with a wavy or lobed margin and a reddish-brown to brown inner surface.

Layered cup fungus (Peziza varia) on a log in Orekhovo, 40 miles north from Saint Petersburg. Russia, August 18, 2017Unnamed Road, Vaskelovo, Leningradskaya oblast', Russia, 188731Observations of Peziza varia in Leningrad Oblast and north-western Russia reveal the fungus grows on logs in various locations. On October 16, 2016, cup-shaped mushrooms were found on a log in Posiolok near Vyritsa, south of Saint Petersburg. Similarly, on August 18, 2017, layered cup mushrooms were observed on a rotten log in Orekhovo, 40 miles north of Saint Petersburg. Additional sightings on the same day in Orekhovo showed the fungus growing on another log. The fungus appears to thrive on decaying wood, with multiple observations in the region indicating its presence on logs in different stages of decomposition. These findings suggest Peziza varia is a common species in the area, able to grow on various types of rotting wood. The sightings took place during different times of the year, indicating the fungus may have a relatively long fruiting period.
