Inocybe erubescens – Deadly fibrecap

Synonyms: Inocybe patouillardii, Inocybe rubescens, Inocybe trinii.

Common name: deadly fibrecap.

Russian names: Volokonnitsa krasneiushchaya, Volokonnitsa Patuyyara.

Extract from Wikipedia article: Inocybe erubescens, also known as I. patouillardii, commonly known as the deadly fibrecap, brick-red tear mushroom or red-staining Inocybe, is a poisonous basidiomycete fungus, one of many in the genus Inocybe and one of the few known to have caused death. It is found growing in small groups on leaf litters in association with beech. All mushroom guidebooks as well as the mushroomers advise that the entire genus should be avoided. The fruit bodies (i.e., the mushrooms) appear in spring and summer; the bell-shaped caps are generally pale pinkish in colour with red stains, with a reddish-pink stipe and gills.

AI-generated description

Inocybe erubescens is a species of mushroom that belongs to the genus Inocybe. It is characterized by its reddish-brown cap, white gills, and distinctive odor. In St. Petersburg and Leningrad Oblast, it typically grows in wooded areas, parks, and gardens from July to September. In north-western Russia, it is commonly found in coniferous and mixed forests, often associated with spruce, pine, and birch trees. The fungus is considered rare and potentially poisonous due to its toxicity.

AI-generated summary of observations

Observations of Inocybe erubescens in Leningrad Oblast and north-western Russia reveal its presence in specific habitats. The fungus was found in the Botanic Gardens of Komarov Botanical Institute in Saint Petersburg, Russia on July 28, 2017. Specifically, it was observed growing under maple trees, suggesting a possible association with these tree species. The mushrooms were also found in other areas of the gardens, indicating a relatively widespread distribution within this habitat. The presence of Inocybe erubescens in these locations highlights its ability to thrive in cultivated environments, potentially posing a risk to humans due to its toxic nature. Further observations are needed to fully understand its ecological preferences and distribution in the region. The sightings in July suggest that summer may be a peak period for fruiting body formation of this species.
