Amanita velosa, commonly known as the springtime amanita,[2] or bittersweet orange ringless amanita[3][4] is a species of agaric found in California, as well as southern Oregon and Baja California. Although a prized edible mushroom, it bears similarities to some deadly poisonous species.

Description

It is part of

amatoxins and ibotenic acid.[3][5] It is distinguished from other species in section Vaginatae by its lack of any kind of umbo on its pileus, its short pileus striae, and its distinct pale orange to pale salmon coloration when young. Its coloration can become more brownish with age and entirely white specimens are occasionally seen as well.[3] Like many other Amanita, the gills are white, but occasionally have a distinct pinkish or orangish tint.[3][5] In older specimens, the odor can become pungent and fishy.[2][6]

The cap is 5–15 cm wide, convex then plane, with an orange-pink or salmon-like color; it usually has a white universal veil patch.[7] The gills are adnexed to free, close and white (or pinkish with age).[7] The stalk is 5–15 cm long, and 1–3 cm wide.[7] The volva is white, saclike and sheathes the stalk base.[7] The spores are white, smooth, elliptical, and inamyloid.[7]

Similar species

The deadly

fruiting body ages, making it important to collect only specimens that have all of their identifying characteristics intact.[9] A. calyptratoides is very similar.[10]

Distribution and habitat

A. velosa is a late-season mushroom in its range of occurrence, being primarily found in the coastal regions of

ectomycorrhizal relationship with young oak trees.[2][5][8]

The species is also reported to have been found in association with aspen and conifers in the Sierra Nevada,[2] with one report of it being found growing with spruce in the eastern United States' Great Smoky Mountains National Park.[5]

Edibility

It is considered to be an outstanding edible species with a distinctively sweet or nutty flavor,[2][6] but great caution must be exercised to properly identify it due to its similarity to deadly species.[9]
