| 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 derived from the description of Corner & Bas (1962). | ||||||||
| pileus | Corner & Bas (1962): 20 - 40 mm wide, grayish mouse-color, becoming planar, dry; context white, soft; margin sulcate-striate; universal veil as large flat gray patches. | ||||||||
| lamellae | Corner & Bas (1962): free, crowded, white, 4 mm broad; lamellulae not described. | ||||||||
| stipe | Corner & Bas (1962): 50 - 80 × 5 mm, equal, hollow, pale silvery gray, minutely fibrillose, not squamulose, exannulate; universal veil: as sheathing, cyathiform volva, closely fitting gray, 10 × 10 mm, with narrow free edge. | ||||||||
| odor/taste | not described. | ||||||||
| macrochemical tests |
none described. | ||||||||
| pileipellis | not described. | ||||||||
| pileus context | not described. | ||||||||
| lamella trama | not described. | ||||||||
| subhymenium | not described. | ||||||||
| basidia | Corner & Bas (1962): 47 - 60 × 10 - 13 µm and 30 - 45 × 10 - 13 µm, "dimorphic." | ||||||||
| universal veil | not described. | ||||||||
| stipe context | not described. | ||||||||
| partial veil | absent. | ||||||||
| lamella edge tissue | not described. | ||||||||
| basidiospores | Corner & Bas (1962): "8 - 9 × 7 - 8.5 µm or 8 - 11 × 7 - 10 µm"; apiculus not described; contents monoguttulate; color in deposit not described. [Note: There is no explanation for the two sets of spore measurements in the original text. We have not estimated a range for Q.—ed.] | ||||||||
| ecology | not recorded. | ||||||||
| material examined | Corner & Bas (1962): SINGAPORE: Botanic Gardens, Garden’s Jungle and Reservoir Jungle, E. J. H. Corner s.n. (no herbarium, as "Amanitopsis 2," no exsiccatum). | ||||||||
| discussion |
Corner & Bas (1962): "It is not certain that this species is related to A. vaginata. Apparently, the gray volva falls apart rather easily and its lower part is adherent to the base of the stipe. Moreover, the spores being comparatively small, it is still possible that the present species belongs to the group of A. farinosa. "However, two watercolor drawings (no. 2b) by Ridley’s artist originally referred to the present species by the senior author, show very slender specimens, which have a small, nearly naked, striate pileus with a depressed center, are entirely gray, except the whitish volva, and have an exannulate stipe. Unfortunately, the volva and the base of the stipe are rather vague in these drawings. They strongly remind one of a very slender form of typical A. vaginata. They may also represent the gray forms included by Petch (1910: 347) in his Amanitopsis endochorda (see discussion under A[manita] angustilamellata)." [Note: At present, we do not know anything about the paintings attributed to "Ridley's artist" or where they might be located unless they are with Corner's watercolors in L. We also do not know the identity of Ridley.—ed.] | ||||||||

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.
