Floccularia albolanaripes is a species of fungus in the family Agaricaceae. Mushrooms are characterized by their yellow caps with a brownish center and scales over the margin, and the conspicuous remains of a partial veil that is left on the stipe. The species grows in the Pacific Northwest and the Rocky Mountains of North America, and in India.

Taxonomy

The species was first described as Armillaria albolanaripes by American mycologist George F. Atkinson in 1908. The type specimens were collected from Corvallis, Oregon on November 6, 1906. It was known as an Armillaria for several decades until members of that genus with amyloid spores and lacking black rhizomorphs were transferred to Floccularia in 1987.

Description

The cap is convex to flattened (sometimes with a shallow umbo), measuring Шаблон:Convert in diameter. Its color is bright-yellow to orange-yellow and then later brownish, and it has flattened brownish scales over the center. The whitish cap margin is rolled inward. The well-separated gills have tooth-like edges, and an adnate attachment to the stipe, sometimes with a notch. They are initially white before turning cream in maturity. The stipe measures Шаблон:Convert long by Шаблон:Convert wide, and is roughly the same width throughout. Shiny with a light yellow-brown base color, it has one to several cottony zones of partial veil remnants. The flesh is firm, and white to yellow under the cap cuticle. It has no distinguishable odor and a mild taste. F. albolanaripes mushrooms are edible.

The spore print is white. Spores are ellipsoid, smooth, and measure 6–8 by 4–4.5 µm.

Similar species

The base form of species Floccularia luteovirens is similar in appearance, but can be distinguished from F. albolanaripes by its brighter yellow cap color with raised scales on the surface, and yellowish gills. F. luteovirens forma straminea (which has sometimes been defined as a distinct species, F. straminea) is another lookalike with similar coloration and habitat preferences, but its cap features shaggy scales arranged in concentric zones, and it has light yellow gills.

Habitat and distribution

Шаблон:Mycomorphbox The fruit bodies of Foccularia albolanaripes grow singly to scattered under conifers. In North America, it is found in the Pacific Northwest and the Rocky Mountains, where it occurs in the spring and summer. A snowbank mushroom, it is often found around the edge of melting snowbanks, or shortly after the snow has melted. In Kashmir, India, it grows in a suspected mycorrhizal association with Pinus wallichiana.
