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.

intro |
|
pileus |
46 mm wide, white except for approx. buff disc, broadly convex to almost plane, slightly viscid, silky fibrillose; context white, quickly oxidizing red, then approx. salmon buff; margin strongly striate (0.2-0.3R); universal veil ??. |
lamellae |
free, moderately distant, white in side view, relatively thick, marginate with orange brown remnants of partial veil; lamellulae ??. |
stipe |
62 × 9 mm, light buff, narrowing upward, decorated above with fibrillose-floccose scales, nearly glabrous below, scales darker orange-brown than stipe surface; bulb lacking??; context ??, stuffed, becoming hollow, with central cylinder ?? mm wide; exannulate; universal veil as saccate volva, white or whitish, ??. |
odor/taste |
Odor slightly of "chlorine." Taste not recorded. |
macrochemical tests |
none recorded. |
lamella trama |
bilateral, divergent; wcs = ?? µm; ??; subhymenial base comprising divergent cells intercalary, singly or in chains of two, clavate to obclavate (e.g., 24 × 11.5 µm) to elongate to elongate with bifurcate apex (e.g., 50 × 14.5 µm) and occasional divergent filamentous, undifferentiated hyphae; filamentous, undifferentiated hyphae 2.0 - 9.5 µm wide, branching; terminal, inflated cells occasional in subhymenial base, clavate, of form similar to that of intercalary cells of same region; vascular hyphae ?? µm wide, ??. |
subhymenium |
wst-near = ?? µm; wst-far = ?? µm; cellular (pseudoparenchymatous), dominated by globose to subglobose to pyriform to ellipsoid cells in two to three layers below longest basidia/-oles, with two to three cells between bases of shortest and longest basidia/-oles of given region, with branching structure apparent in immature regions (typically then with cells partially inflated), with basidia in mature regions of hymenium arising mostly from globose to subglobose cells (e.g., 11.5 × 11.5 µm) and infrequently from partially inflated cells (e.g., branched and 19.0 × 13.0 µm). |
basidia |
?? × ?? µm, ??-sterigmate, with sterigmata up to ?? × ?? µm; clamps rare. |
basidiospores |
[40/1/1] (9.5-) 10.2 - 14.0 (-16.5) × (6.0-) 6.4 - 7.5 (-9.0) µm, (L = 12.1 µm; W = 6.9 µm; Q = (1.48-) 1.59 - 1.96 (-2.0); Q = 1.76), hyaline, colorless, thin-walled, smooth, amyloid, dominantly elongate, occasionally ellipsoid, infrequently cylindric, usually adaxially flattened, often expanded at one end; apiculus sublateral, cylindric, rather stubby; contents multi- to (dominantly) monoguttulate; ?? in deposit. |
ecology |
Solitary. At 1900 - 2100 m elev. In cloud forest or in mixed forest including scattered Quercus seemanii. |
