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.

| 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 the collector's notes and photographs and original research of RET. |
| pileus |
??, pale gray to silvery gray, becoming broadly convex; context white to off-white dark gray below pileipellis, proportionately thick over stipe; margin striate (0.2 - 0.25R), becoming rimose in only known specimen; universal veil as irregular common submembranous patches, stretched by pileus expansion, becoming ochraceous. |
| lamellae |
free, close, off-white, minutely flocculose, marginate (pale gray); lamellulae ??. |
| stipe |
??, striate at the apex in region of pale gray to gray surface pulverulence; context ??; exannulate; universal veil submembranous, saccate, constricted, flaring above, gray on inner surface. |
| odor/taste |
not recorded. |
macrochemical
tests |
none recorded. |
| basidia |
dominantly 4-sterigmate. |
| universal veil |
On pileus, interior: filamentous undifferentiated hyphae ?? μm wide, with somewhat thickened walls, irregularly disposed, sometimes abruptly curving up to 180°; inflated cells dominating, terminal singly, with walls somewhat thickened |
| partial veil |
absent. |
| lamella edge tissue |
sterile. |
| basidiospores |
[13/1/1] (9.5-) 10.2 - 12.2 (-13.0) × (8.5-) 9.3 - 10.7 (-12.0) μm, (L = 11.3 μm; W = 10.1 μm; Q = (1.08-) 1.09 - 1.16 (-1.21); Q = 1.12), hyaline, colorless, thin-walled, smooth, inamyloid, adaxially flattened, subglobose to broadly ellipsoid; apiculus ??; contents ??; ?? in deposit. |
| ecology |
Solitary. Under Interior Live Oak (Quercus
wislizenii) or with Quercus, Madrone
(Arbutus menziesii, and California Bay
(Umbellularia californica). |

| discussion |
This collection was originally proposed to be
A. protecta by mushroomobserver participants
and was detected as distinct by
comparison of sequences of the nrITS locus.
We provide comparison of the sporographs of the two
species below. One should be cautious about this
comparison because the number of spores found on the
single specimen of the present species represent a
very small sampling. Moreover, the specimen
is immature; most of the hymenium was not yet
bearing spores when the basidiome was
dried.
This species was formerly called
"Amanita sp-C18" in these pages.
