| 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 material is based upon original research by R. E. Tulloss. |
| pileus |
?? - ?? mm wide, grayish brown over disc, paler (to white) toward margin, ??; context ??; margin plicate-striate, ??; universal veil as membranous patches, gray in exsiccatum. |
| lamellae |
??, ??, white, with margin grayish brown; lamellulae ??. |
| stipe |
?? - ?? × ?? - ?? mm, white, narrowing upward; context ??; exannulate; universal veil as saccate volva, dominately white, with upper part of limb grayish in exsiccatum. |

| pileipellis |
80 - 135 µm thick, with scant to absent suprapellis; suprapellis (when present) up to 20 µm thick, colorless, comprising gelatinized tissue; subpellis 80 - 125 µm thick, brownish orange, comprising ungelatinized tissue; filamentous, undifferentiated hyphae ?? µm wide, ??; vascular hyphae ?? µm wide, ??. |
| pileus context |
filamentous, undifferentiated hyphae ?? µm wide, ??; acrophysalides ??; vascular hyphae 2.1 - 5.0 µm wide, occasionally locally coiled or tangled. |
| lamella trama |
bilateral; wcs = ?? µm; central stratum containing plentiful fusiform to clavate to ovoid intercalary cells up to 11.5 µm (rarely to 17.5 µm) wide; subhymenial base with plentiful inflated cells [elongate to narrowly clavate (up to 51 × 17.5 µm) or globose to subglobose to ellipsoid to ovoid to broadly clavate (up to 48 × 32 µm), often intercalary, with walls often slightly thickened, often penetrating subhymenium] and plentiful filamentous, undifferentiated hyphae; filamentous, undifferentiated hyphae 1.8 - 7.8 µm wide, frequently branching in subhymenial base, often constricted at septa; terminal, divergent, inflated cells not uncommon, pyriform, (e.g., 37 × 23 µm), with walls slightly thickened; vascular hyphae not observed; clamps not observed. |
| subhymenium |
wst-near = 45 - 50 µm; wst-far = 70 - 75 µm; usually with clearly branching structure, locally cellular (pseudoparenchymatous); with 2 - 3 cells between bases of longest and shortest basidia/-oles in given region, with 2 - 3 cells between bases of longest basidia/-oles and central stratum, with basidia arising commonly from partially inflated and uninflated hyphal segments and from obclavate to branched to clavate to subglobose inflated cells (almost always with major diameter perpendicular to central stratum). |
| basidia |
52 - 69 × 13.5 - 16.8 µm, dominantly 4-, occasionally 2-sterigmate, with sterigmata up to 7.0 × 3.0 µm; clamps not observed. |
| basidiospores |
[20/1/1] 10.0 - 12.0 (-13.0) × (8.5-) 8.7 - 10.0 (-12.4) µm, (L = 11.0 µm; W = 9.5 µm; Q = (1.05-) 1.09 - 1.24 (-1.29); Q = 1.17), hyaline, colorless, ??-walled, smooth, inamyloid, subglobose to broadly ellipsoid; apiculus ??; contents ??; color in deposit unknown. |
