Extract from Wikipedia article: Pholiotina rugosa is a common lawn mushroom which is widely distributed and especially common in the Pacific Northwest. It also grows on woodchips, rich soil and compost. It has been found in Europe, Asia and North America. It contains the same mycotoxins as the death cap. It is more commonly known as Conocybe filaris as this is the name it is likely to appear under in field guides. However, Conocybe filaris is a junior synonym of Pholiotina rugosa. Pholiotina rugosa has also been placed in the genus Conocybe, but its morphology and a 2013 molecular phylogenetics study place it in the genus Pholiotina. Pholiotina fimicola, which grows on dung and rich soil in North America is a possible synonym. Pholiotina arrhenii has also been considered a possible synonym, but a molecular phylogenetics study found it to be a distinct species.
Conocybe filaris is a species of mushroom that belongs to the family Bolbitiaceae. It has been found in St. Petersburg, Leningrad Oblast, and other parts of north-western Russia, typically growing on grasslands, meadows, and along roadsides. The fungus produces small, bell-shaped caps that are 0.5-2 cm in diameter, with a conical to convex shape and a striated margin. The gills are adnexed to free, and the spores are brownish-purple. In north-western Russia, Conocybe filaris often fruits from June to September, preferring moist and fertile soils.
Pholiotina rugosa (Conocybe filaris) mushrooms on mulch in Sosnovka Park. Saint Petersburg, Russia, August 28, 2016Unnamed Road, Sankt-Peterburg, RussiaObservations of Conocybe filaris in Leningrad Oblast and north-western Russia have shown that the fungus can thrive in various environments. In Sosnovka Park, Saint Petersburg, the mushrooms were found growing on mulch on August 28, 2016. The species has also been spotted in other areas with rich organic matter, such as wood chips and compost heaps. Conocybe filaris has been observed to fruit in late summer to early fall, typically from July to September. The fungus tends to grow in clusters or scattered individuals, often in association with other fungal species. Its habitat preferences suggest that it is a saprotrophic species, playing a role in decomposing organic matter in these ecosystems. Further observations are needed to fully understand the ecological niche of Conocybe filaris in this region. The species' distribution and abundance may be influenced by factors such as soil moisture and temperature.
