Amanita canescens
Introduction[edit]
Amanita is a fairly large genus of gilled mushrooms, estimated to contain about 1,100 species worldwide. Nearly all species form ectomycorrhizae with forest trees such as oaks, hickories, beeches, and many genera of conifers. This association is beneficial to both the host trees and the fungus—the plant trades photosynthates in exchange for fungus-acquired nutrients from the soil. Amanitas will therefore most often be encountered in forested areas as long as the mycorrhizal tree species are present. The geographical “hot spot” that has the greatest diversity of Amanitas in North America, and perhaps the entire world, is the Southeastern/Gulf Coast regions of the United States. [1]
Genus: Amanite[edit]
Spore print is white, and spores are amyloid or inamyloid; lamellae are free, that is, the lamellae are not attached to the stipe; universal veil is present; presence of a partial veil that leaves a persistent or fugacious annulus, with the exception of section Vaginatae that lacks a partial veil. The universal veil is a membranous tissue that encloses the entire mushroom in the button stage. The universal veil can take on two different forms: in one form a membranous volva (sac) remains at the base of the stip, in the other form, the universal veil leaves fragments in the form of patches, warts or powdery material on the pileus surface, and there may or may not be a few velar patches, warts or ridges on the stipe base.[1]
Section: Validae[edit]
This section shares the following set of features: bulbous stipe base, persistent partial veil, and universal veil remnants in the form of warts on the pileus surface. The color of the pilei ranges from white to bright yellow to drab grays and reddish-brown. Some have the odor of cut raw potatoes and a few have fruity odors. Some species develop pinkish or reddish-brown stains when handled or bruised. The spores are amyloid.[1]
Amanita canescens[edit]
These mushrooms have a gray to brownish gray pileus surface that is covered with velar warts over much of the surface. The stipe is white but the surface fibrils often discolor dull orange. A membranous annulus is present, whose underside also has an orangish color. A membranous volva is absent, but remnants of the universal veil as irregular patches can be present on top of the swollen base.[1]
