1. Amanita sp-53, Muttontown Pres., Oyster Bay, Nassau Co., Long Isl., New York, U.S.A.
The information below is based on a single collection and original research on that collection by R. E. Tulloss.
The cap of this taxon is up to 50+ mm wide, brown, viscid, and has its pigment distributed in such a way as to appear to have very fine, dark, radial hairs in the skin of the cap. There is no data on the flesh of the cap. The cap's margin is sulcate-striate for 50% or more of the cap's radius. Volval remnants on the cap may be absent or may take the form of a grayish white, off-center, membranous patch.
The gills have a pinkish or pale orangish tint.
The stem appears to be whitish at first, and yellows with age. The stipe has a ring that is striate above and "woolly" below. At the stem base, the volva is saccate, grayish white, and membranous.
No information is available on the odor or taste of this mushroom.
The spores of this species measure (10.5-) 10.8 - 12.5 (-14.0) × (7.4-) 7.5 - 8.7 (-11.0) μm and are ellipsoid and inamyloid. From what is known to date, the basidia probably bear basal clamps.
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.
