2. Amanita sinicoflava, Sussex Co., New Jersey, U.S.A.
sinicoflava has a Chinese yellow or "curry
powder colored" or yellow-olivaceous or olive-tan
cap that is 25 - 70 mm wide. Striations run inward from
the cap edge for about 40% of the radius. Warts or
patches of pallid to grayish volva are often left on the
cap, but can be washed off easily by rain.
The gills of this
species turn grayer as the mushroom ages. The very
plentiful short gills are truncate.
This mushroom has a
whitish, exannulate stem (60 - 135 × 4 - 12 mm)
decorated with somewhat darker fibrils. The volval
remnants are saccate and submembranous and becoming
progressively grayer with age beginning from the top of
the sac and working downward.
The spores measure
(8.0-) 9.1 - 12.1 (-15.4) × (7.0-) 8.4 - 11.5 (-15.4) µm and
are globose to subglobose (very rarely broadly ellipsoid)
and inamyloid. Clamps are absent from bases of basidia.
The species occurs with oak, beech, and diverse conifers. It is distributed widely in the northeastern and north central United States and, probably, in southeastern Canada—fruiting from late June to October. Prior to its description, this species was often determined as "Amanita fulva" and might be found in herbaria under that name. Among taxa that are most similar macroscopically are A. mortenii Knudsen & Borgen, A. olivaceogrisea Kalaméés, and A. submembranacea (Bon) Gröger.—R. E. Tulloss.
Due to delays in data processing at GenBank, some accession numbers may lead to dead pages.
These pages will eventually be made live, so try again later.
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
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.

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.
