Amanita pachycolea, commonly known as the western grisette[1] or the Stuntz's great ringless amanita,[2] is a species of agaric fungus in the family Amanitaceae.
The cap is brown, sometimes lighter near the margin. The gills are white with gray-brown edges, staining orange-brown in age. The stipe is white to brownish with a fibrillose or scaly surface. The base is enclosed by a thick, felty volva, which is white in youth, then yellow or brownish, sometimes becoming reddish in age.[3]
A. pachycolea was recognized as a distinct species by mycologist Daniel Elliot Stuntz, and published in 1982 by Harry Delbert Thiers. It is classified in Amanita section Vaginatae, which includes species with conspicuous radial striations on the cap (8–20 centimetres (3–8 inches) wide), inamyloid spores, and the absence of a ring on the stipe (10–25 cm long, 1–3 cm wide, tapering upward).[4][5]
Found in western North America, it associates with conifers in coniferous and mixed forests. The mushroom is edible, but not recommended due to possible confusion with toxic Amanita species.[1]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
