| 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 and Bas (1962). | ||||||||||||||||||||
| pileus | from Corner and Bas (1962): 60 mm wide, leaden gray, darker in center, becoming plane with depressed center, slightly viscid; context white, soft, 3 mm thick above stipe, 0.5 mm thick at mid-radius; margin striate (0.5R); universal veil absent. | ||||||||||||||||||||
| lamellae | from Corner and Bas (1962): free, crowded, white, 5.5 mm broad, thin, with 74 primaries; lamellulae with 0 - 1 between each pair of otherwise adjacent lamellae. | ||||||||||||||||||||
| stipe | from Corner and Bas (1962): 125 mm × 7 mm wide, pallid-whitish, minutely cottony, almost smooth; context hollow; exannulate; universal veil sheathing, saccate, membranous-subcarnous, white, 20 × 20 mm, attached only at very base of stipe, with edge not lobed, with rather narrow limbus internus inserted on inner side of volva some millimeters above connection with stipe. | ||||||||||||||||||||
| macrochemical tests |
none reported. | ||||||||||||||||||||
| pileipellis | rather thin; suprapellis gelatinized; subpellis not gelatinized; filamentous hyphae of subpellis 1.5 - 3 µm wide, with brown contents, interwoven, subradially arranged; clamps not observed. | ||||||||||||||||||||
| pileus context | not described. | ||||||||||||||||||||
| lamella trama | not described. | ||||||||||||||||||||
| subhymenium | not described. | ||||||||||||||||||||
| basidia | not described. | ||||||||||||||||||||
| universal veil | from Corner and Bas (1962): On inner and exterior surfaces: filamentous hyphae 3 - 5 (-8) µm wide, interwoven, sublongitudinally oriented. In interior: filamentous hyphae dominating; inflated cells very scattered; clamps not observed. | ||||||||||||||||||||
| stipe context | from Corner and Bas (1962): longitudinally acrophysalidic; filamentous hyphae not described; acrophysalides "large," up to 420 × 60 µm; vascular hyphae rather numerous, up to 18 µm wide; clamps not observed. | ||||||||||||||||||||
| partial veil | absent. | ||||||||||||||||||||
| lamella edge tissue | not described. | ||||||||||||||||||||
| basidiospores | from Corner and Bas (1962): [-/-/-] 9.0 - 11.0 × 7.1 - 8.7 µm, (Q = 1.1 - 1.4; Q = 1.25 - 1.3), colorless, thin-walled, smooth, broadly ellipsoid, inamyloid; apiculus "medium-large"; contents mostly monoguttulate; color in deposit not recorded. [Note: Spores from fresh material were reported to measure 9 - 11.5 × 7 - 8.5 µm.—ed.] | ||||||||||||||||||||
| ecology | from Corner and Bas (1962): "Terrestrial in jungle." | ||||||||||||||||||||
| material examined | from Corner and Bas (1962): MALAYSIA: PAHANG—Unkn. Distr. - S of Kampung Kuala Retang, "Tembeling Estate" [4°03'00" N/ 102°19'00'' E, 101 m], 8.xi.1930 E. J. H. Corner s.n. (L, as "Amanitopsis 2 pr.p."—1 exsiccatum). | ||||||||||||||||||||
| discussion | from Corner and Bas (1962): "The [Malayasian] specimen described above differs from A. ovalispora Boed. from Java (of which we were unable to study material) by (i) the gray cap lacking brown, (ii) the wider volva, and (iii) the broader spores, viz. 9 - 11 × 7 - 8.7 µm against 8 - 11 × 6 - 7 µm. The spores depicted by Boedijn have a length-breadth ratio between 1.4 and 1.6, those of the [Malayasian] specimen 1.1 - 1.4. Nevertheless...[the two] collections may be conspecific.

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.
