  1. Amanita sp-Thai2, Thailand.  2. Amanita sp-Thai2, Thailand. |
| intro | While several collections Thailand and Cambodia may be assignable to the group of specimens we include in this code numbered provisional taxon. The necessary microscopy has not been completed. Quantitative information of all sorts is needed concerning this mushroom. |
| cap | The cap of this species is 40 - 100 mm wide, pale yellow to yellow to yellow-orange, or yellow to nearly white with a pale orange center. The cap lacks red areas entirely in the available photograph of a single collection. The cap's flesh is up to 10± thick above the stem. The cap's margin is striate, with striations up to 12± mm long. Volval remnants are absent from the cap. |
| gills | The gills are free or narrowly attached to the stem, crowded? and pale yellow to yellow, (in one specimen yellowish as dried), but not bright yellow. Nothing is known about the short gills. |
| stem | The stem is up to 80 mm long, yellow above, paler yellow below, pallid as dried, and narrowing upward. Its context is said to have a 4 mm wide central cylinder containing a "gel" [Note: This may be an interpretation of watersoaked hyphae firmly packed in the central cylinder.—ed.]. The ring is placed high on the stem, is membranous or submembranous, thin, pale yellow to pale yellow-orange, striate above, whitish on the underside, entirely whitish as dried, possibly fragile, and skirt-like. The sack-like volva is proportionately smaller than in A. sp-Thai3 and A. sp-Thai4, with its limb(s) sometimes very irregularly shaped (e.g., the portion of the limb on one side of the stipe much longer than the portion of the limb on the other side of the stipe), white on its outer surface, and reported to lack an internal limb. |
| odor/taste | The odor of this mushroom is said to be mild, and the taste has not been recorded. |

| ecology |
Scattered to subgregarious. Cambodia: With dipterocarps. Thailand: common in dipterocarp woodland. Arora says local informants said a red-capped species grew "way up on the mountain." Hence, this nonumbonate entity (somewhat reminiscent of central African taxa such as >A. mafingensis, A. masasiensis, and A. tanzanica appears to be found at relatively low altitudes in SE Asia. | ||||||||

Spore data sets and their composite
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.
