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 material is derived from the protolog of the present taxon and Pegler (1986). |
| pileus |
protolog: 64 mm wide, dark umber, hemispheric to convex, obtusely umbonate; context thick, reddish below gluten layer; margin not described; gluten layer concolorous, appearing to form network on pileus surface.
Pegler (1986): 20–60 mm wide, dark reddish brown to umbrinous, paler with age, hemispheric to convex, obtusely umbonate; context reddish just below "volva," white elsewhere, up to 10 mm thick over stipe; margin decurved, nonstriate, initially appendiculate with few “velar squamules”; gluten layer as viscid to glutinous matrix.
Vrinda & RET: 35 - 70 mm wide, "cocoa brown" (6E6) to "golden blonde" (5C6), frequently with aereolate cracking in a net-like pattern exposing context uncovered by gluten; context dull white to white, up to 5 mm thick over stipe; margin non-striate, originally bearing remains of gluten retaining hyphae originally interwoven with similar hyphae of stipe; gluten layer providing pigment. |
| lamellae |
protolog: approximate, density not described, whitish, "slightly tinged like...flesh with red," 6 mm broad, "sickle-shaped"; lamellulae not described.
Pegler (1986): free to adnexed, crowded, white with pinkish tint, up to 7 mm broad, ventricose; lamellulae of at least two lengths.
Vrinda & RET: free, crowded, white in side view, ventricose, up to 6 mm wide, with entire edges concolorous with faces; lamellulae of diverse lengths. |
| stipe |
protolog: 64 × 10.5 mm, white, cylindric, fibrillose below cortina; bulb not described; context solid; partial veil as "spongy" cortina; gluten layer not described.
Pegler (1986): 20–60 × 3–11 mm, off-white, cylindric, dry; bulb not described; context solid; partial veil cortinoid, whitish, forming more or less floccose annular zone on stipe; gluten layer not described.
Vrinda & RET: 35 - 100 × 5 - 9 mm, dull white, dry, central, cylindric, smooth above last point of contact with stipe; bulb absent; context solid; exannulate; gluten layer absent. |

| pileus context |
Pegler (1986): filamentous “very inflated” [?], 5 – 25 µm wide, with hyphae just below gluten layer brown-walled; clamp connections present. |

not described. |

| discussion |
The only comment in the protolog is that the fungus seemed similar to L. glioderma.
The species is apparently dry stemmed and can be assigned to sect. Limacella.
Pegler had no more information to go on than did the original authors of this species. Perhaps, the differences in the macroscopic descriptions may be due to Pegler's having taken more advantage of the copies of the original drawings than the authors took of the originals they had in hand. |
