| 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 not directly from the protolog of the present taxon and is based on the revision in Wartchow et al. (2009). | ||||||||||||||||||||
| pileus | from protolog: small to medium size, 40 - 60 mm wide, plane to depressed, distinctly yellow (1A5) with white over margin, viscid; context not described; margin finely striate, sometimes crenate; universal veil as yellowish-white (1A2) patches over disc. | ||||||||||||||||||||
| lamellae | from protolog: free, yellowish white (1A2); lamellulae truncate to rounded-truncate, one for every 2-5 lamellae. | ||||||||||||||||||||
| stipe | from protolog: 80 - 120 × 8 - 9 mm, cylindric, central, slightly thicker toward base, smooth, yellowish-white (1A2); bulb 22 × 19 mm; context not described; exannulate; universal veil as limbate volva, friable, concolorous with stipe, with limbus internus remnants encircling stipe base. | ||||||||||||||||||||
| odor/taste | from protolog: Odor pleasant. Taste not recorded. | ||||||||||||||||||||
| pileipellis | from protolog: as cutis comprising undifferentiated filamentous hyphae ca. 1.2 µm wide, with gelatinized suprapellis through which whole hyphae loosely interwoven. | ||||||||||||||||||||
| pileus context | from protolog: filamentous undifferentiated hyphae ca. 12 µm wide; acrophysalides not described. | ||||||||||||||||||||
| lamella trama | from protolog: bilateral, divergent; … undifferentiated filamentous hyphae1.2 - 2.5 µm wide. | ||||||||||||||||||||
| subhymenium | from protolog: cellular, up to 23 µm thick, as 2-4 layers of more or less isodiametric cells, 7.5 - 12.5 × 7.5 - 11.2 µm. [Note: The values for wst-near and wst-far that are provided in the protolog are impossible given the size and layering of the cells of the subhymenium. There must have been a typographical error or some other mistake.—ed.] | ||||||||||||||||||||
| basidia | from protolog: (37-) 39 - 44 (-47) × 8.7 - 12.5 µm, 4-sterigmate; clamps “absent.” | ||||||||||||||||||||
| universal veil | from protolog: On pileus: undifferentiated filamentous hyphae 1.2 - 3.7 µm wide; inflated cells hyaline, thin-walled, ovoid or subglobose or as elongate terminals elements (22-) 30 - 50 (-54) × (12-) 17.5 - 41 (-48) µm. On stipe: undifferentiated filamentous hyphae 1.2 - 3.7 µm wide; inflated cells hyaline, thin-walled, as inflated terminal elements or globose to subglobose (42-) 45 - 57 (-65) × (32-) 35 - 42 µm. | ||||||||||||||||||||
| stipe context | from protolog: longitudinally acrophysalidic; filamentous undifferentiated hyphae 1.2 - 7.5 µm wide, dominant; acrophysalides thin-walled, up to 102 × 26 µm. | ||||||||||||||||||||
| basidiospores |
from protolog: [40/2/1] 8.7 - 10.0 (-11.1) × (5.0-) 6.2 - 7.5 (-8.7) μm, (L = 9.2 - 9.4 μm; L' = 9.3 μm; W = 5.6 - 6.5 μm; W' = 6.0 μm; Q = (1.29-) 1.33 - 1.74 (-2.0); Q = 1.42 - 1.70; Q' = 1.56), hyaline, colorless, smooth, thin-walled, inamyloid, without germ pore, ellipsoid to elongate, occasionally broadly ellipsoid [, rarely cylindric]; apiculus not described; contents guttulate; color in deposit not described. from type study of Wartchow et al. (2009): [40/1/1] (7.0-) 8.0 - 9.5 (-10.0) × (5.5-) 6.0 - 7.0 μm, (L = 8.9 μm; W = 6.3 μm; Q = (1.21-) 1.25 - 1.51 (-1.55); Q = 1.41). from type study and revision of Wartchow et al. (2012): [105/2/2] (7.0-) 8.0 - 11.0 (-11.5) × (5.4-) 5.7 - 6.8 (-7.2) μm, (L 8.9 - 9.9; L' = 9.5 μm; W = 6.3 - 6.4; W' = 6.4 μm; Q = (1.21-) 1.25 - 1.66 (-1.68); Q = 1.41 - 1.53; Q' - 1.49). | ||||||||||||||||||||

Spore data sets and their composite
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.
