intro

Olive text indicates a specimen that has not been thoroughly examined (for example, for microscopic details) and marks other places in the text where data is missing or uncertain.

The following material is based on molecular research of L. V. Kudzma and other original research of R. E. Tulloss.

pileus

?? mm wide, yellow tan to light tan, brownish tan to brown over disc, with brown over marginal striation and darker brown ring over inner ends of those striations, rounded conic at first, becoming convex, evenutally concave in age, with pronounced central umbo; context not recorded; margin nonappendiculate, striate (ca. 0.35R); universal veil absent.

lamellae

free to remote, ??, ?? in mass, white in side view, becoming light brownish gray in exsiccatum; lamellulae not observable due to conditions of exsiccata.

stipe

?? × ?? mm, with white base color, sometimes with covering of fine fibrils concolorous with palest brown over striations and nearest to margin in younger material; context not described; exannulate; universal veil saccate, membranous and entirely white at first, becoming gray (and probably submembranous) with age and exposure, attached to stipe base in lower part, then abruptly flaring and loosely enclosing stipe in upper part (about three-quarters of sac's length).

odor/taste

not recorded.

macrochemical
tests

none recorded.

partial veil

absent.

ecology

In small group. at 400 m elev. In mixed forest including Acer, Betula, Populus tremuloides, Tsuga canadensis, and Pinus strobus.

discussion

Originally this species with a distinctive graying volva and zonate pileus was mistaken for A. sinicoflava in the field; however, the pileus of the latter species is not zonate and is differently pigmented. The following figure compares what is known of the spores size and shape of the two taxa:
