AI-generated description

Echinoderma asperum is a species of fungus in the family Agaricaceae. In St. Petersburg, Leningrad Oblast, and north-western Russia, it typically grows in coniferous and mixed forests, often on acidic soils. Fruit bodies appear from late summer to autumn, characterized by a small to medium-sized cap with wavy or split margins, and a long, thin stem. The cap is usually brownish-grey to grey-brown, and the gills are crowded and free from the stem. This fungus is considered rare in the region, but can be found in undisturbed forests with abundant organic matter.

AI-generated summary of observations

Observations of Echinoderma asperum in Leningrad Oblast and north-western Russia reveal distinct characteristics. The fungus has a warty or scaly cap, as seen on mulch in the Botanic Gardens of Komarov Botanical Institute in Saint Petersburg. Similar specimens were found on roadsides, such as east from Kuzmolovo in northern Saint Petersburg, with possible variations like L. hystrix. These sightings occurred during late summer, specifically on September 18, 2013, and September 8, 2016. The fungus appears to thrive in urban and roadside environments, suggesting adaptability to human-altered landscapes. The observed caps display distinctive warts or scales, consistent with the species' description. Further study could elucidate the ecological preferences and distribution of Echinoderma asperum in this region. The species seems to be present in the area during late summer months.
