Amanita porphyria, commonly known as the Grey Veiled Amanita, is a basidiomycete fungus belonging to the Amanita genus. It is characterized by a greyish to brownish cap with faint white warts, which can reach up to 10 cm in diameter. The white to grey stem, which may grow up to 12 cm tall, features a distinct ring and a bulbous base with a membranous, sack-like volva. Advanced scientific research has shown that Amanita porphyria contains low levels of the toxins α-amanitin and phalloidin, which can cause mild toxic effects when ingested in large quantities. However, it is generally considered to be less toxic than other Amanita species, such as Amanita phalloides. The Grey Veiled Amanita is widely distributed across Europe and parts of North America, including parts of Russia, where it is known as Мухомор порфировый. It forms ectomycorrhizal relationships with various tree species, particularly coniferous trees like pines and spruces, and is typically encountered during late summer and autumn. Amanita porphyria produces white, elliptical spores that measure approximately 8-11 µm by 5-7 µm. The spore print is also white, making it a key characteristic for identification. An estimated 1-2 million spores are produced per fruiting body, which are dispersed by wind and rain. Although Amanita porphyria is not as toxic as some other Amanita species, it is still important to exercise caution when foraging, as the Grey Veiled Amanita can be easily confused with other toxic Amanita species. Ingestion of Amanita porphyria may lead to mild gastrointestinal symptoms and, in rare cases, neurological effects such as confusion and drowsiness. In German, this fungus is known as Porphyreller Wulstling, a name that reflects its characteristic color and its close relationship with the Amanita genus.
