Taxonomic status: This is a Pholiota.
Notes: Current name: Pholiota angustifolia A.H. Sm. & Hesler, The North American species of Pholiota: 204 (1968) as replacement name, non Pholiota appendiculata Peck 1904.
Types: UNITED STATES: New York: Bronx Co., New York Botanical Garden (approx. 40.8621°N, 73.8769°W, alt. approx. 750 m a.s.l.) on soil in lawn, 4 Sep. 1912, W.A. Murrill (Holotype. herbarium acc. no. NY 814857, HJB1000285; Isotype. herbarium acc. no. WTU-F-039677, HJB1000315).
Diagnosis: Pileus convex, not fully expanding, slightly gibbous, rather thick and fleshy, cespitose, 5 cm. broad; surface viscid, silky and also finely imbricate-squarmulose, rosy-isabelline, cremeous on the disk, margin deflexed, concolorous, appendiculate with triangular fragments of the slight, evanescent veil; context white, thick at the center, with nutty lavor; lameilae sinuate, broad behind and tapering in front, quite narrow, arcuate, very much crowded, pale-cream-colored, not darkening on drying, the edges pallid and distinctly crenate or dentate; spores ellipsoiđ, smooth, pale-clay-colored in mass, pale-melleous under the microscope, 6-7 X 3-4 μ; stipe equal, spongy-stuffed with creamy-white pith, glabrous at the apex, white above, concolorous below, revolute-squamulose, 4 cm. long, 1 cm. thick. Type collected on the ground at the base of a sugar maple tree on a Jawn in the New York Botanical Garden, September 4, 1912, W. A. Murrill (herb. N. Y. Bot. Gard.). DISTRIBUTION: Known only from the type locality.
Commentary: The spores are thick-walled and very small (5–6.5 × 3–4 µm) with a tiny but distinct germ pore, supporting the recombination into Pholiota. The name chosen by Smith and Hesler as a replacement synonym was selected to avoid the competing homonym Pholiota appendiculata (Peck 1905).
