intro	The macroscopic description is derived from Michael Kuo's annotation of the fresh material of this collection.
cap	The cap of this mushroom is 20–60 mm wide, rose-brown to reddish brown, convex becoming planoconvex, smooth to finely fibrillose, and viscid at first. The flesh of the cap is whitish except for being pinkish in the upper part. The cap's margin is not striate, and is incurved even in age, and it may split with age and drying of the fruiting body. Gluten ??.
gills	The gills are free or narrowly attached, close, and white (becoming cream and spotted with pink). The short gills are plentiful.
stem	The stem is 30 – 100 x 5 – 10 mm (width measured at the top), narrowing upward, and slightly enlarged at the base. The stem has a ground color that is whitish or pinkish; it is smooth above an annular zone, and shaggy with reddish pink scales below the annular zone. The flesh of the bulb is whitish and becomes pink in the stem's base. The stem's ring is fragile, fragmenting, originally funnel-shaped, and whitish to pinkish.
odor/taste	Both odor and taste suggest flour or meal (i.e., are "farinaceous").
spores	The spores measure (3.6-) 3.9 - 5.0 (-5.5) × (2.9-) 3.0 - 3.8 (-4.5) μm and are broadly ellipsoid to ellipsoid (sometimes subglobose) and inamyloid. Clamps are common at the bases of basidia.
discussion	A second collection that may represent the same taxon as the present one, unfortunately proved to consist only of a single immature fruiting body.—R. E. Tulloss and Michael Kuo.

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.

Information below comes From annotation of fresh material by M. Kuo and revision by RET and CRC. DNA sequencing was performed under the direction of Dr. József Geml.

pileus

20–60 mm wide, rose-brown to reddish brown to brownish-red, red more dominant at first, sometimes subvirgate, convex becoming planoconvex, smooth to finely fibrillose, viscid at first, later dry; context whitish except pinkish in upper part, "thick" over stipe; margin nonstriate, incurved even in age, becoming rimose with age; gluten ??.

lamellae

free or narrowly attached, close, white to off-white, becoming cream and spotted with pink; lamellulae plentiful.

stipe

30–100 x 5–10 mm (apex), whitish at apex, elsewhere with ground color whitish or pinkish, narrowing upward to subcylindric, slightly enlarged at base, smooth above annular zone, shaggy with reddish pink scales or reddish-brownish peronate in zones below (and separated from) annular zone; bulb ??; context whitish, becoming pink in stipe base; partial veil, superior, fragile, cortinate, gluten coated, fragmenting, whitish to pinkish; gluten ??.

odor/taste

Odor and taste farinaceous.

macrochemical
tests

KOH - on pileus, olive-gray; on flesh, yellowish.

pileipellis

absent.

lamella trama

bilateral, divergent; ??. [Note: Difficult to rehydrate in material examined.—ed.]

basidia

?? × ?? μm, 4-sterigmate, with sterigmata up to ?? × ?? μm; clamps common at bases of basidia.

gluten layer

On pileus, in older material: gluten layer 25 - 35 μm thick, colorless; ??.

stipe context

longitudinally acrophysalidic; filamentous undifferentiated hyphae 2.0 - 13.0 μm wide, with the broadest having walls up to 0.5 μm thick, plentiful to dominating, dominating exclusively near surface, branching, ??; acrophysalides up to 284 × 17.5 μm relatively common locally away from surface, with broadest having walls thickened as in filamentous hyphae; vascular hyphae apparently present ??; clamps relatively common.

partial veil

absent in material examined.

ecology

Solitary to scattered. Illinois: Under Pinus resinosa in plantation (Kuo 08290201) or in leaf litter under mixed hardwoods including Robinia, Fraxinus, Quercus, Carya, Cornus, and Acer with P. resinosa and P. strobus nearby (Kuo 07220705).

material examined

U.S.A.: ILLINOIS—Coles Co. - Fox Ridge St. Pk., 22.vii.2007 M. Kuo 07220705 (in herb. M. Kuo; RET, nrITS & nrLSU seq'd.). Piatt Co. - Monticella, Lodge Pk., 29.viii.2002 M. Kuo 08290201 (in herb. M. Kuo; RET, nrITS & nrLSU seq'd.). INDIANA—Montgomery Co. - Waveland, Shades St. Pk. [39.9378° N/ 87.0894° W, 223 m], 28.viii.2012 Stephen Russell s.n. [mushroomobserver #107737] (RET 532-10, nrLSU seq'd.).

discussion

A sporograph comparison of the present species with material identified as A. glischra is provided here:

Unfortunately, Kuo 07220705 is immature and no spores could be found on it. The conspecifity of the two collections is supported by other morphology and by nrITS and nrLSU sequence data.

Spore data for collections
provisionally identified as: Limacella sp-L-IL01 Tulloss & Kuo

Spore data sets and their composite

Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer; and explanations prepared for this site talk about specimen-observer pairs associated with each data set. Combining more data into a single data set is non-optimal because it obscures observer differences (which may be valuable for instructional purposes, for example) and may obscure instances in which a single collection inadvertently contains a mixture of taxa.
