The editors of this site owe a great debt to Dr. Cornelis Bas
whose famous cigar box files of Amanita nomenclatural information
gathered over three or more decades were made available to RET for computerization
and make up the lion's share of the nomenclatural information presented on this site.

| intro |
The following text may make multiple use of each data field.
The field may contain magenta text presenting data from a type study
and/or revision of other original material cited in the protolog of the present taxon.
Macroscopic descriptions in magenta are a combination of data from the protolog and
additional observations made on the exiccata during revision of the cited original
material.
The same field may also contain black text, which is data from a revision of the present
taxon (including non-type material and/or material not cited in the protolog).
Paragraphs of black text will be labeled if further subdivision of
this text is appropriate.
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 is primarily derived from the revisions of Bas (1969) and Reid (1980). The protolog is very minimal.
The basidiomes of this species are large to very large (Bas 1969). |
| pileus |
from protolog: 102 - 152 mm wide, pale ocher, convex, then flattened, obtuse; context not described; margin faintly striate; universal veil as darker concentric scales.
from Bas (1969): 90 - 170 (-240) mm wide, buff, often with pinkish or yellowish or brownish tinges, slightly darker towards disc, convex to planar to planoconvex, dry; context whitish, turning pinkish when exposed: margin appendiculate; universal veil as covering of scales, patches or floccose crusts.
from Reid (1980): 50 - 300 mm wide, salmon-buff to light brick-red, convex then flattened, with "streaky marginal area" sometimes showing "yellowish brown droplets, sometimes shiny in place in exsiccata; context not described; margin not described; universal veil as "numerous concentric zones of darker, more or less innate scales," barely visible [against light pinkish ground] in exsiccata. |
| lamellae |
from protolog: free, crowded, ochraceous (the color of "new washleather"), broad, attenuated "behind."
from Bas (1969): free, crowded, whitish to cream at first, later becoming ochraceous, sometimes turning pinkish where bruised, rather broad, ventricose; lamellulae attenuate.
from Reid (1980): "ochraceous to orange-yellow and remaining so when dried," staining paper of spore print yellow. |
| stipe |
from protolog: 178 × 25 mm, concolorous, smooth, at last striate, fibrillose; bulb turbinate; context solid; partial veil superior, pendulous, "sometimes double"; universal veil not mentioned.
from Bas (1969): 110 - 190 × 15 - 30 mm, pale buff to pale vinaceous brown, paler and striate above partial veil, minutely fibrillose below, more or less cylindric; bulb clavate or broadly clavate or sublgobose or subnapiform, immarginate, about 50 - 80 × 40 - 90 mm; context solid, whitish, pinkish when exposed; partial veil subapical, pendent, membranous, white to creamy buff, broad, striate above; universal veil absent [or, probably, as ring-like fragments of limbus internus below partial veil on stipe—called "lower ring" by Bas.—ed.] or (rarely) as slight ridge on top of bulb.
from Reid (1980): 65 - 250 × 20 - 60 mm, concolorous with cap except for "pink flush at apex" above partial veil; bulb marked, napiform or more [ob]conic and rooting, immarginate, 30 - 80 mm wide, in button up to 30 - 40 mm wide while pileus only "few" mm wide; context not described; partial veil ochraceous brown, membranous, striate [above]; universal veil as "second ring" immediately above bulb on base of stem in all (6) specimens seen. |
| odor/taste |
from Bas (1969): Odor strong, unpleasant. Taste not recorded. |
macrochemical
tests |
none recorded. |
| pileipellis |
from Bas (1969): as dense layer, brownish yellow in alkaline solution, not or slightly gelatinized; filamentous hyphae 3 - 10 μm wide, interwoven, often with somewhat refractive contents; vascular hyphae scattered. |
| pileus context |
not described. |
| lamella trama |
from Bas (1969): bilateral; clamps present. |
| subhymenium |
from Bas (1969): subramose to subcellular. |
| basidia |
from Bas (1969): ca. 40 - 50 × 10 - 20 μm, 4-sterigmate; clamps distinct when young. |
| universal veil |
from Bas (1969): On pileus: brownish yellow, with elements slightly refractive in alkaline solution; comprising two layers; outer (submembranous) layer of filamentous hyphae (predominant, interwoven, 3 - 8 (-14) μm wide, with slightly thickened walls) and inflated cells (scattered, slenderly clavate to elongate, up to 130 × 30 μm) and inner (floccose) layer of filamentous hyphae (rather abundant, interwoven, thin-walled) and inflated cells [small (rather abundant, mainly clavate to pyriform, 20 - 60 × 12 - 30 μm, terminal singly or in short chains) or elongate (scattered)]. On stipe: in part called "lower ring" by Bas; similar to outer layer on pileus. [Note: Because the material of what Bas calls the "lower ring" is consistent with that of the universal veil remnants on the pileus, we treat the "lower ring" as remnants of a limbus internus of the universal veil.—ed.]
from Reid (1980): On pileus: In two layers; membranous cohesive outer layer forming scant evanescent patches (filamentous hyphae 2 - 10 μm wide, hyaline, branched, with walls thin to "distinct," very indistinctly encrusted with amorphous matter; clamps very occasional); more floccose inner layer possibly collapsing to form more or less "innate" scales [inflated cells in chain, with intercalary elements up to 70 × 15 μm, with uncommon terminal elements "ovate" and up to 24 × 17 μm]. |
| stipe context |
from Bas (1969): longitudinally acrophysalidic; filamentous hyphae scattered, 3 - 8 μm wide; acrophysalides abundant, up to 500 × 30 μm. |
| partial veil |
from Bas (1969): called "upper ring" by Bas; filamentous hyphae densely branching, comprising net-like structure; with covering of material [probably from lamella edge tissue] on upper surface (12 - 30 μm wide, spheropedunculate to broadly clavate to pyriform inflated cells). |
| lamella edge tissue |
from Bas (1969): "scanty" in material examined; inflated cells clavate to subglobose, up to 35 × 20 μm. [Note: See also cells on upper surface of partial veil, above.—ed.] |
| basidiospores |
from Bas (1969): [80/11/4] 9.0 - 11.0 × 5.5 - 7.0 μm, (Q = 1.30 - 2.0; Q = 1.50 - 1.80), colorless, hyaline, thin-walled, amyloid, ellipsoid to elongate, sometimes ovoid or obovoid; apiculus not described; contents subguttulate; white in deposit.
from holotype (Reid 1980): (7.0-) 7.5 - 10.0 × (4.2-) 5.0 - 7.0 μm, hyaline, thin-walled, amyloid; apiculus; not described; contents not described; color in deposit not recorded. [Note: Without values of Q, a sporograph cannot be generated. Estimation of a range of Q was not possible from this data.]
from Lilly Pilly Gully material spore print (Reid 1980): [-/-/-] 7.0 - 12.0 × 5.5 - 7.0 μm, (est. Q = 1.25 - 1.70), amyloid; apiculus not described; contents not described; white in deposit. |

| discussion |
from Bas (1969):
"The second (lower) ring if present is very probably formed by the limbus internus of the volva. It is very distinct on the coloured plate published by Cleland (1934: pl. 1) and the photograph published by Gilbert (1941: pl. 61). In the first case it is situated half-way up the stem, in the second, on the top of the bulb
"The wide variation of the ornamentation of the cap is probably due to the peculiar structure of the volva on the cap and the dry pileipellis. As long as the outer layer of the volva is present, patches or flat scales are formed. But where the outer layer peels off the remnants of the less coherent inner layer are dispersed over the surface of the cap.
"Amanita ochrophyllahas some remarkable characters: (i) The inner layer of the volva close to the pileipellis is more friable than the submembranous outer layer in which inflated cells are scarce and mostly elongate. (ii) The limbus internus of the volva is rather coherent and forms a second ring below the one formed by the partial veil. (iii) Though the part of the volva over the cap is well-developed and even submembranous in its outer layer, there are rarely remnants of the volva at the base of the stem.
"Because of these features the taxonomic position of A. ochrophylla is somewhat isolated. However, the likewise isolated A. gymnopus from Malaya also has a submembranous volva over the cap and a glabrous bulb. Moreover, it has ochraceous yellow gills, rubescent flesh, and a strong smell. But it has no second ring, much smaller spores, and is provided with rhizoids at the base of the stem.
"Because the outer layer of the volva is more membranous than its inner parts and because one of the specimens studied (Sydney, No. 58) has a slight volval ridge at the base of the stem, A. ochrophylla seems to connect the highly aberrant A. gymnopus with subsection Limbatulae."
The anatomy of the present species needs to be further resolved by revision of multiple collections. For example, attention needs to be directed to determining the range of cell forms and sizes in the lower layer of the universal veil. |
