1. Amanita sp-C03, San Gabriel Mtns., N of
Pasadena, Los Angeles Co., California, U.S.A.
For the present please refer to the "technical" tab of this species.
This species has the habit of A. solitaria of Europe, with yellowish and greenish tints on all parts of the fruiting body.—R. E. Tulloss
Tulloss & G. Wright
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.
The following text may make multiple use of each data field.
A field may 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 original research of R. E. Tulloss and field notes of Greg Wright.
85 - 160 mm wide, white with a green tint ("somewhat like the lamellae of Russula delica" per G. Wright), plane to broadly convex, glabrous, not viscid; context white, thick; margin appendiculate with white material of both partial and universal veils; universal veil as numerous small and flat patches or as pyramidal warts, white, rather dense over disc, sparse over margin.
narrowly adnate, close to subcrowded, greenish white to greenish buff, of medium breadth, with edges white and fimbriate; lamellulae truncate.
110 - 120 × 21 - 24 mm, with green tint (concolorous with pileus), moderately appressed scaly in lower part; bulb ventricose; context white; partial veil superior, white, membranous, soon tattered; universal veil lacking.
Odor slightly rancid-musty when freshly cut. Taste "typical for section Lepidella" (per G. Wright), suggests hazelnuts.
10% KOH soln. - negative on pileus surface and context, negative on lamellae. Wieland test - positive for amatoxins, but not as strongly positive as in A. ocreata.
UV light - most of pileus, lamellae, and stipe and small regions (mostly near surfaces) of pileus and stipe contexts flourescing dull yellow.
?? mm thick; suprapellis ?? mm thick, gelatinized; subpellis ?? mm thick; filamentous, undifferentiated hyphae ?? - ?? µm wide, subradially arranged, interwoven, branching, sometimes with somewhat expanded terminal cells; vascular hyphae present.
bilateral, divergent; central stratum ??; filamentous hyphae ??; inflated cells ??; vascular hyphae 2.8 - 7.0 µm wide, very tangled and dense in some regions.
uninflated hyphal segements in branching structure.
57 - 71 × 8.0 - 11.2 µm, 4-, 2-, and 3-sterigmate, with sterigmata up to 8.0 µm long; clamps plentiful.
On pileus: filamentous, undifferentiated hyphae 2.4 - 7.3 µm wide, branching, interwoven, abundant; inflated cells plentiful, irregularly disposed, not rehydrating well, subglobose to broadly ellipsoid (up to 53 × 50 µm) to elongate (up to 70 × 35 µm); vascular hyphae up to 5.9 µm wide. On stipe base: absent.
longitudinally acrophysalidic; filamentous, undifferentiated hyphae 2.1 - 8.4 µm wide, branching, ??; acrophysalides up to 280 × 35 µm; vascular hyphae up to 16.1 µm wide, branching, common, mostly sublongitudinally arranged?.
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.
