Extract from Wikipedia article: Pholiota squarrosa, commonly known as the shaggy scalycap, the shaggy Pholiota, or the scaly Pholiota, is a species of mushroom in the Strophariaceae family. Common in North America and Europe, it is often an opportunistic parasite, and has a wide range of hosts among deciduous trees, although it can also infect conifers. It can also live as a saprobe, deriving nutrients from decomposing wood. The mushroom is typically found growing in clusters at the base of trees and stumps. Both the cap and the stem are covered in small, pointed scales that are pointed downward and backward. The crowded gills are yellowish, then later rust-brown. The mushroom has an odor that, depending on the author, has been described as resembling garlic, lemon, radish, onion, or skunk. It has a strong taste, resembling radishes. Once thought to be edible, it is now considered and known to be poisonous, especially if consumed in combination with alcohol. The mushroom contains unique chemicals thought to help it infect plants by neutralizing defensive responses employed by them. The very similar P. squarrosoides differs in having a paler cap that is sticky between the scales, and smaller spores.
Pholiota squarrosa is a species of mushroom characterized by its scaly cap, which is typically 3-8 cm in diameter, yellow-brown to dark brown in color, and covered with recurved, pointed scales. The gills are crowded, pale yellow to greenish-yellow, and the stem is 4-10 cm tall, 0.5-1.5 cm thick, and scaly like the cap. In St. Petersburg, Leningrad Oblast, and north-western Russia, Pholiota squarrosa has been found growing on various substrates, including stumps, logs, and living trees, particularly conifers such as pine and spruce. It typically fruits from July to November, with peak abundance in August and September. The species is common in the region's forests, parks, and urban areas, often forming large clusters or rings on the ground.
