Amanita aureosolea is a species in the group with a pigmented, friable volva that darkens with agea nd exposure. In the present, the original color of the volva is orange-yellow.
The cap of A. sp-N29 is 46 - 79 mm wide, chestnut brown at first, later becoming sordid brown from the margin inward, unchanging when cut or bruised, planoconvex, and umbonate. The cap flesh is white, sometimes with a brown area just under the cap's skin and is unchanging when cut or bruised. The cap's margin is striate for 25% to 40% of the cap radius and nonappendiculate. Volval remnants on the cap are present as small crumb-like warts or slightly larger warts or crust-like patches, easily removed, probably yellow originally, becoming brown to gray with orange-brown tint or dark brown, and finally gray brown to brownish gray with pale edges.
The gills are free or receding, with or without connected lines on the top of the stem (10× lens), subcrowded to crowded, orangish cream to pale brownish white to dingy white in mass and cream to dingy cream to dingy white or watersoaked in side view. The short gills are truncate, greatly varying in length, plentiful, and unevenly distributed
The skirtless stem is 111 - 168 × 7.5 - 13 mm, pale brown to pale orangish-brown to pale orangish cream ground color, unchanging when cut or bruised, and decorated with orange-brown to brown fibrils. The stem's flesh is white to off-white to pale tan, unchanging when cut or bruised, and hollow. The volval remnants on the stem are in the form of a strangulate, fragile volva, ochraceous to bright yellow orange below stipe base and in one or two rings immediately above and/or below the strangulate (stretched-looking, undecorated) region, with the highest such ring 21 - 40 mm from the stem's base. These rings often become orange-brown with time. Additional volva remnanats are occasionally found as gray warts and small patches above the uppermost ring.
The odor of this species is not noticeable in young material; older material was described to RET as having the odor of fried potatoes. The taste has not been recorded.
The spores measure (8.2-) 9.2 - 12.0 (-13.5) × (7.5-) 8.8 - 11.0 (-12.5) µm and are globose to subglobose to broadly ellipsoid and inamyloid. Clamps are probably absent from bases of basidia.
Tulloss nom. prov.
"Golden Shod Ringless Amanita"
aureus, "golden" + solea, "sole" [of the foot or of a shoe]; so named for the color of the universal veil material found below the base of the stipe; hence, "golden-shod"
Due to delays in data processing at GenBank, some accession numbers may lead to unreleased (pending) pages.
These pages will eventually be made live, so try again later.
Olive text indicates a specimen that has not been

The following is based upon original research of R. E. Tulloss.
46 - 79 mm wide, chestnut brown at first, becoming sordid brown from the margin inward, unchanging when cut or bruised, planoconvex, umbonate, sometimes with umbo set in broad central depression, viscid becoming tacky, shiny becoming dull; context white or watersoaked or white with brown under pileipellis, unchanging when cut or bruised, 4 - 7.5 mm thick at stipe, thinning evenly for most of radius, then membranous for last few mm (up to 10%) of radius in larger basidiomes, membranous for one quarter of radius in smaller ones; margin striate (0.25R - 0.4R), nonappendiculate; universal veil as small crumb-like warts or slightly larger warts or crust-like patches, smooth to verruculose (10× lens), subfelted, detersile, original color unknown, becoming brown to gray with orange-brown tint or dark brown, then becoming gray brown to brownish gray with pale edges.
free or receding, with or without decurrent line on stipe apex (10× lens), subcrowded to crowded, orangish cream to pale brownish white to dingy white in mass, cream to dingy cream to dingy white or watersoaked in side view, infrequently forking, 6.5 - 9.5 mm broad; lamellulae truncate, greatly varying in length, plentiful, unevenly distributed
111 - 168 × 7.5 - 13 mm, pale brown to pale orangish-brown to pale orangish cream ground color, unchanging when cut or bruised, decorated with orange-brown to brown fibrils (sometimes with umbrinous tint or becoming very dark brown to black in age) in a chevron-like pattern, minutely punctate near the apex in age, narrowing upward, flaring (sometimes barely) at apex; context white to off-white to pale tan, unchanging when cut or bruised, hollow, with white cottony fibrils in central cylinder of 2 - 6 mm wide; exannulate; universal veil as strangulate volva, ochraceous to bright yellow orange below stipe base and in one or two rings which delimit the strangulate (undecorated) region, with highest such ring 21 - 40 mm from stipe base, these rings may become orange-brown or brownish red with time, occasionally also as gray warts and small patches above the uppermost ring.
Odor indistinct, or (in age) like fried potatos (J. Lennie, Berkeley, California). Taste not recorded.
Solitary to subgregarious. In loam under broad-leaved trees or in mixed broad-leaf/conifer forests or near Betula or under Betula and Populus.

The ochraceous remains of the universal veil at the stipe base and the brown color of the universal veil on the pileus in the youngest specimen seen suggest that the universal veil is yellow-orange to ochraceous at first, then becomes brownish red to brown, and eventually gray.

Spore data for collections provisionally identified as: Amanita aureosolea Tulloss
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.
