Taxonomic status: This is a Cortinarius.
Types: UNITED STATES: Massachusetts: Stockbridge (approx. 42.2876°N, 73.3204°W, alt. approx. 250 m a.s.l.) on soil in woodland, 3 Sep. 1896, W.A. Murrill, W.G. Thompson (Holotype. herbarium acc. no. NY 814870, HJB1000276).
Diagnosis: Pileus large, thick, fleshy, convex to plane, solitary, 5-10 cm. broad; surface smooth, glabrous, viscid, luteous, margin ochraceous, entire, not striate; lamellae sinuate, ventricose, crowded, melleous to ferruginous; spores ellipsoid, smooth, subfulvous in mass, melleous under the microscope, 7—8.5 X 4-5 μ; stipe equal or tapering upward, smooth, dry, glabrous, pearly-white, 5-7 cm. long, 7-15 mm. thick; veil fibrillose, slight, evanescent.
Commentary: The spores are amygdaloid, small (approx. 8 × 5 µm) and pale brown; no pleurocystidia or cheilocystidia were found. Unfortunately, it was not possible to generate any DNA sequence data. Based on the morphology, including the black and white photo this is most likely a species of Cortinarius. The name C. luteus was used by Peck (1890) already for a species with a type from “Sevey, New York” (fide Kauffman 1932; Peck 1890 appears to have forgotten to mention the type information), which is currently considered a synonym of what is referred to by Liimatainen et al. (2022) as Aureonarius limonious. We leave it to Cortinarius experts to find the correct name for this taxon.
