This taxon is rather slender with rather marked striations on the cap's edge. It has been found in central Mexico in open Oak woodland over a deep layer of volcanic tuff.
Compare to Amanita sp-M22, which is more robust and has minimal cap edge striations.—R. E. Tulloss

intro
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 by R. E. Tulloss.
ecology
At 2640 m elev. In open Quercus woodland on deep volcanic tuff.
material examined
MEXICO: TLAXCALA—Mpio. Panotla - 1 km E of San Francisco Temezontla [19°20’41” N/ 98°16’31” W, 2640 m], 15.vii.1996 A. Montoya Esquivel & R. E. Tulloss [Tulloss 7-15-96-F] (RET 255-4; TLXM), 17.vii.1996 A. Montoya Esquivel & R. E. Tulloss [Montoya E. 1558] (RET 251-10; TLXM).

Information to support the viewer in reading the content of "technical" tabs
can be found here.
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.
