Due to delays in data processing at GenBank, some accession numbers may lead to unreleased (pending) pages.
These pages will eventually be made live, so try again later.
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 not directly from the protolog of the present taxon and not cited as the work of another researcher is based on original research by R. E. Tulloss.
48 - 55 mm wide, gray, paler (to nearly white) toward margin, with markedly truncate disc, convex, viscid; context white, unchanging when cut or bruised, 3 - 4 mm thick at stipe; margin sulcate (0.55 - 0.65R as dried); universal veil as squamules over disc and scattered dark gray, flat or subpyramidal warts or small patches.
free, close, light cream to white, 3 - 4 mm broad, thin, entire; lamellulae ??.
110 × 8 - 10 mm, white, cylindric, pruinose above, decorated with fibrillose squamules or dark gray scales; context white, stuffed, becoming hollow; exannulate; universal veil as cupulate volva, white, short in proportion to length of stipe, mostly adnate to stipe.
Odor lacking. Taste not recorded.
39 - 53 × 11.1 - 13.0 µm, thin-walled, dominantly ??-sterigmate, with sterigmata up to 7.0 × 2.7 µm; clamps not observed.
[40/2/1] (9.0-) 9.1 - 10.5 (-15.7) × (7.2-) 8.0 - 9.0 (-13.9) µm, (L = 9.9 - 10.0 µm; L’ = 9.9 µm; W = 8.4 - 8.5 µm; W’ = 8.4 µm; Q = (1.10-) 1.11 - 1.26 (-1.33); Q = 1.18; Q’ = 1.18), hyaline, colorless, thin-walled, smooth, inamyloid, broadly ellipsoid to ellipsoid, infrequently subglobose, often at least somewhat adaxially flattened, occasionally expanded at one end; apiculus sublateral, cylindric, proportionately rather small; contents monoguttulate; color in deposit unknown.
Subgregarious. Honduras: At 1200 - 1300 m elev. In solid Pinus oocarpa stand with only limited ground cover.

Tulloss & G. M. Muell.
Spore data for collections provisionally identified as: Amanita sp-HON11 Tulloss & G. M. Muell.
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.
