| intro | The following is derived entirely from the provisional description of Corner and Bas (1962). | ||||||||||||||||||||
| pileus | from Corner & Bas (1962): 60 mm wide, leaden gray, darker over center, with dark innate streaks, becoming concave and slightly umbonate, subviscid, smooth; context white, firm, 7 mm thick over stipe, 2 - 2.5 mm thick at mid-radius; margin nonstriate; universal veil absent. | ||||||||||||||||||||
| lamellae | from Corner & Bas (1962): free, crowded, white, then cream, narrow, rather thick, 3 mm broad, 130 primaries; lamellulae subtruncate to attenuate, 1 - 7 between each pair of otherwise adjacent lamellae. | ||||||||||||||||||||
| stipe | from Corner & Bas (1962): 160 × 12 mm (from dried specimen), lower two-thirds (above universal veil) pale grayish white and finely fibrillose, upper third white and slightly pruinose; bulb apparently not pronounced, but subradicating; context solid , firm; exannulate; universal veil limbate as in A. phalloides, with limb 20 mm high. | ||||||||||||||||||||
| odor/taste | from Corner & Bas (1962): Odor faint, not unpleasant. Taste not recorded. | ||||||||||||||||||||
| macrochemical tests |
none recorded. | ||||||||||||||||||||
| pileipellis | from Corner & Bas (1962): filamentous hyphae 2 - 5 µm wide, distant and irregularly disposed near surface, slightly wider and crowded and radially to subradially oriented below surface, with gray or umber contents. | ||||||||||||||||||||
| pileus context | not described. | ||||||||||||||||||||
| lamella trama | not described. | ||||||||||||||||||||
| subhymenium | not described. | ||||||||||||||||||||
| basidia | from Corner & Bas (1962): 4-sterigmate. | ||||||||||||||||||||
| universal veil | not described. | ||||||||||||||||||||
| stipe context | from Corner & Bas (1962): longitudinally acrophysalidic. | ||||||||||||||||||||
| partial veil | absent. | ||||||||||||||||||||
| lamella edge tissue | from Corner & Bas (1962): inflated cells numerous. | ||||||||||||||||||||
| basidiospores | from Corner & Bas (1962): [-/-/-] 7.2 - 7.9 × 5.6 - 6.7 μm, (Q = 1.10 - 1.30; Q = 1.20), colorless, thin-walled, smooth, amyloid, subglobose to broadly ellipsoid or obovoid, apiculus "small"; contents cloudy vacuolate; color in deposit not recorded. In the fresh state, the spores were said to measure 7 - 8.5 × 5.5 - 6.5 μm. | ||||||||||||||||||||
| ecology | from Corner & Bas (1962): Terrestrial. | ||||||||||||||||||||
| material examined | from Corner & Bas (1962): SINGAPORE: Bukit Timah, 21.viii.1939 E. J. H. Corner s.n. (L, one dried specimen as "Amanitopsis 6"). | ||||||||||||||||||||
| discussion |
from Corner & Bas (1962): "The specimen preserved was already in a bad condition before drying. It is impossible to study the structure of the volva and the base of the stipe, while the description is rather vague on these points. Moreover, it is difficult to know from a single specimen whether the absence of an annulus is incidental or characteristic. "The present species seems to be most closely related to A. modesta Corner & Bas. It is similar in many respects, such as the color of the pileus, the closeness of the narrow gills, the shape and size of the spores, and perhaps the shape of the base of the stipe. It seems to differ only in the very long, somewhat grayish stipe, the absence of an annulus, and the streaky pileus. From A. elephas Corner & Bas it differs in the crowded narrow gills and the exannulate stipe." The following diagram provides comparison of the sporographs of the present species, A. elephas, and A. modesta: | ||||||||||||||||||||

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.
