name	Amanita sp-53
name status	cryptonomen temporarium
author	Tulloss
english name	"Londo Mollari's Slender Caesar"
images	1. Amanita sp-53, Muttontown Pres., Oyster Bay, Nassau Co., Long Isl., New York, U.S.A.
intro	The information below is based on a single collection and original research on that collection by R. E. Tulloss.
cap	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.
gills	The gills have a pinkish or pale orangish tint.
stem	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.
odor/taste	No information is available on the odor or taste of this mushroom.
spores	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.
discussion	From the minimal information available, the present taxon seems most similar morphologically to A. incarnatifolia Zhu L. Yang.—R. E. Tulloss
