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 |
The following text may make multiple use of each data field.
The field may contain magenta text presenting data from a type study
and/or revision of other original material cited in the protolog of the present taxon.
Macroscopic descriptions in magenta are a combination of data from the protolog and
additional observations made on the exiccata during revision of the cited original
material.
The same field may also contain black text, which is data from a revision of the present
taxon (including non-type material and/or material not cited in the protolog).
Paragraphs of black text will be labeled if further subdivision of
this text is appropriate.
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 notes and
photographs of collectors; molecular research of
Dr. Linas V. Kudzma, and other original research of
RET. |
| pileus |
35 - 60 mm wide, pale brown to dull brown, darker brown
over disc at first, hemispheric
when young, becoming convex with small umbo;
context thin, white;
margin tuberculate-striate (0.35R),
nonappendiculate; universal veil membranous,
white with rusty stains and gray underside; sometimes
absent. |
| lamellae |
free, white, with edges even or minutely fimbriate
(10× lens); lamellulae subattenuate,
sparse, irregularly distributed. |
| stipe |
up to 110 mm × 10 mm (width measures at stipe
base), narrowing upward, whitish with brown "snakeskin"
pattern; context not described;
exannulate; universal veil as loose
saccate volval, white with rusty stains, with interior
surface gray. |
| odor/taste |
Odor mild. Taste not recorded. |
macrochemical
tests |
none reported. |
| lamella trama |
bilateral, divergent. |
| basidia |
[small sample] 50 - 62 × 14.8 - 15.2 μm; clamps
not observed. |
| partial veil |
absent. |
| lamella edge tissue |
sterile. |
| basidiospores |
[40/2/1] (9.8-) 10. - 12.8 (-15.5) × (9.0-)
9.5 - 11.8 (-14.0) μm, (L = 11.4 - 11.7 μm;
L' = 11.6 μm; W = 10.6 μm; W' =
10.5 μm; Q = (1.02-) 1.05 - 1.16 (-1.18);
Q = 1.10); Q = 1.10), hyaline, colorless, smooth,
thin-walled, globose to subglobose, infrequently
broadly ellipsoid, adaxially flattened, often expanded
at one end; apiculus sublateral, prominent,
subtruncate to cylindric; contents
monoguttulate, sometimes
with small additional granules; white in deposit. |

U.S.A.:
OREGON—Tillamook Co. -
Cascade Head, 2.ix.1991 Bruce Kuechman s.n. [J. E.
Lindgren 91-35] (RET 084-2, nrITS seq'd.).

| discussion |
RET 084-2 was dried when barely beginning to expand and
bears no spores.
RET 076-7 and 084-2 are accompanied by notes taken
when the material
was fresh. These notes are the source for the
present macroscopic description.
Material included here was originally merged with
Amanita sp-NW04 on this site.
The apparent species have been
separated on molecular grounds.
We were not able to derive nrLSU sequences from either
of the voucher collections of this taxon.
The nrLSU 5' motif is of the form dominant in the
Vaginatae. |
