Extract from Wikipedia article: Gyromitra infula, commonly known as the hooded false morel or the elfin saddle, is a fungus in the family Helvellaceae. The dark reddish-brown caps of the fruit bodies develop a characteristic saddle-shape in maturity, and the ends of both saddle lobes are drawn out to sharp tips that project above the level of the fruit body. The stipe is white or flushed pale brown, smooth on the outside, but hollow with some chambers inside. It is found in the Northern Hemisphere, usually in the late summer and autumn, growing on rotting wood or on hard packed ground. G. infula is considered inedible as it contains the toxic compound gyromitrin, which, when metabolized by the body, is converted into monomethylhydrazine, a component of some rocket fuels. The toxin may be removed by thorough cooking. Gyromitra fungi are included in the informal category "false morels".
Gyromitra infula is a species of fungus that grows in association with trees, typically in sandy or nutrient-poor soils. In St. Petersburg, Leningrad Oblast, and north-western Russia, Gyromitra infula has been found to fruit from May to July, often in coniferous or mixed forests, particularly under pine or spruce trees. It is a relatively common species in the region, with a preference for moist, acidic soils and shaded environments. The fungus produces distinctive brain-shaped or wavy caps that are reddish-brown to dark brown in color, reaching up to 6 cm in diameter.

In the Botanic Gardens of Komarov Botanical Institute, Saint Petersburg, a specimen was found covered with the mold-like fungus Sphaeronaemella helvellae on October 1, 2016. In lower Sergievka Park, Old Peterhof, Gyromitra infula was observed growing on rotten logs and timber on October 5, 2017. The fungus appeared to thrive in decaying wood, suggesting a saprotrophic lifestyle. These sightings indicate that Gyromitra infula is present in the region, often associated with rotting organic matter, and can be found in urban parks and botanical gardens. The observations highlight the diversity of habitats where this species can be encountered in north-western Russia.
