| 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 is based upon original research by R. E. Tulloss. |
| pileus |
40 - 73 mm wide, dull white (paler than 1A2) when very young, then pale grayish buff (4B3) to pale buffy gray (paler than 3B2) without yellow to orange buff, drying sordid cream to pale brownish gray and darker over disc, convex to planoconvex, shiny, glabrous; context ??; margin striate (0.2 - 0.25R), becoming sulcate in age; universal veil as single patch or thin "clumps" [check meaning of this phrase against exsiccata], white, membranous, detersile. |
| lamellae |
free, crowded to moderately crowded, cream to warm buffy white, drying pale cream (close to 4A2) to pale orangish tan (slightly paler and grayer than 10YR 8/8), with fimbriate edges, rather thick; lamellulae truncate, in one to three tiers, many reaching more than half way to stipe. |
| stipe |
? × ? mm, may be long in relation to pileus diameter (1.5 - 2.75 times pileus diameter), white to cream, cylindric, with apex pruinose or finely scaly, finely fibrillose below; context ??, hollow to stuffed and then becoming hollow, with gray stains toward base; exannulate; universal veil as saccate volva, white, interior sometimes drying pale gray, with limb of same height on all sides, somewhat flaring, thick, with limbus internus. |
| odor/taste |
Odor none to faintly of fresh fish. Taste not recorded. |
macrochemical
tests |
none recorded. |
| lamella trama |
bilateral; wcs = 50 - 85 µm; with central stratum including chains of rather short ellipsoid to clavate cells (e.g., 14 × 10.5 µm, 20 × 8.8 µm); filamentous, undifferentiated hyphae ?? µm wide, ??; inflated cells ??; vascular hyphae 2.1 - 17.2 µm wide, rare, infrequently branched. |
| subhymenium |
wst-near = 45 - 95 µm; wst-far = (55-) 80 - 110 µm; a branching structure of diversely shaped inflated cells, locally pseudoparenchymatous, ??. |
| basidia |
49 - 68 × 10.2 - 15.5 µm, thin-walled, dominantly 4-sterigmate, but also occasionally 2-, and less frequently 1- and 3-sterigmate, with sterigmata up to 7.5 × 2.8 µm; clamps probably absent. |
| basidiospores |
[120/6/4] (8.4-) 9.4 - 12.8 (-14.7) × (6.3-) 6.6 - 9.4 (-12.2) µm, (L = 10.9 - 11.6 µm; L’ = 11.3 µm; W = 7.9 - 8.6 µm; W’ = 8.2 µm; Q = (1.14-) 1.23 - 1.60 (-1.84); Q = 1.32 - 1.47; Q’ = 1.39), hyaline, colorless, smooth, thin-walled, inamyloid, broadly ellipsoid to ellipsoid, occasionally elongate, rarely subglobose, at least somewhat adaxially flattened, occasionally expanded at one end, rarely constricted; apiculus sublateral, small, cylindric; contents monoguttulate with additional small granules; color in deposit unknown. |
| ecology |
Solitary, from 1630 to 2600 m elev. Under Pinus arizonica and P. strobiformis or with Pseudotsuga menziesii, P. arizonica, and Abies concolor or with Quercus arizonica, Q. emoryi, Q. hypoleucoides, Juniperus deppeana, Cupressus arizonica, P. chihuahuana, P. discolor, Prunus serotina, and Platanus wrightii or with Quercus and Juniperus. |
