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

send to graphing tool

[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).

material examined

U.S.A.: CALIFORNIA—Contra Costa Co. - Briones Reservoir [37.9214° N/ 122.197° W, 274 m], 15.i.2018 Ben Anderson s.n. [mushroomobserver.org #306746] (RET 822-9, nrITS-LSU seq'd.); Huckleberry Preserve (East Bay Regional Parks) [ca. 37.8423° N/ 122.190° W, ca. 279 m], 18.iv.2008 Debbie Viess s.n. [mushroomobserver.org #7337] (RET 583-2, nrITS & nrLSU seq'd.). Sonoma Co. - Windsor, Shiloh Ranch Regional Pk. [38.5279° N/ 122.7525° W, 205 m], 13.i.2019 Cindy Trubovitz s.n. [mushroomobserver #366273] (RET 872-8, nrITS-LSU seq'd.).

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.
