Species Information

Summary:
Section Fulvescentes which used to be considered a part of Subgenus Telamonia but is not closely related. Features include a hygrophanous pale grayish yellow-brown cap, sometimes with an olivaceous brown tint, pale yellowish brown young gills, a whitish silky-fibrillose stem, an ochraceus yellow universal veil which may leave bands on the stem, mild odor and taste, growth with spruce (at least in northern Europe), and microscopic characters.
Cap:
2.5-4(5)cm across, bell-shaped to conic becoming flat and slightly umbonate, "margin incurved for a long time, even, acute"; +/- hygrophanous, milky-coffee brown to gray-brown or ocher-brown, drying pale ocher; "finely silky to innately fibrillose", when moist micaceous, (Breitenbach), 3.5-6.5cm across, conic to hemispheric, later low convex with umbo; hygrophanous; pale grayish yellow-brown, "sometimes with olivaceous brown tints"; matte, (Knudsen)
Flesh:
thin; light beige to gray-brown, (Breitenbach), yellowish brown to yellowish gray (Knudsen)
Gills:
"ascending and broadly attached", broad, 38-42 reaching stem, 3-5 subgills between neighboring gills; pale beige-brown when young, later yellow-brown to ocher-brown; "edges undulating and slightly ciliate", (Breitenbach), medium-spaced; pale yellowish brown, when old becoming yellow-brown, (Knudsen)
Stem:
6-10cm x 0.6-1(1.2)cm, cylindric, widening slightly toward base, hollow, fragile; "slightly circumcinct to irregularly banded from ocherish velar flocci on a whitish to light ocherish background", soon becoming bald, (Breitenbach), 5-13cm x 0.5-1.1cm, cylindric to somewhat clavate; "whitish silky-fibrillose", (Knudsen)
Veil:
"universal veil ochraceous yellow", "forming complete and incomplete girdles on stem", (Knudsen)
Odor:
none (Breitenbach), indistinct (Knudsen)
Taste:
mild, insipid, (Breitenbach)
Microscopic spores:
spores 6.8-8.3 x 5.5-6.3 microns, broadly elliptic to "almost subglobose", "weakly to moderately verrucose"; basidia 4-spored, 28-35 x 8-10 microns, "clavate to ventricose", with basal clamp connection; pleurocystidia not seen, marginal cells 18-30 x 5-10 microns, basidiole-like; septa with clamp connections, (Breitenbach), spores 7.5-8 x 5.5-6 microns, nearly round to broadly oval, "moderately verrucose, weakly to moderately dextrinoid", (Knudsen)
Spore deposit:
rust-brown (Breitenbach)
Notes:
Harrower(1) assigned a BC collection sequence 70 to Cortinarius ochrophyllus. It is also found in Europe (Knudsen(1)). Morphological correlation is desirable.
