Full name: Hebeloma vatricosoides (Peck) Murrill (1917)
Published: N. Amer. Fl. 10 (3): 219 (1917)
Taxonomic status: Heterotypic synonym of H. excedens
Notes: Originally collected in 1887 and reported as Inocybe vatricosa ( Rep. (Annual) Trustees State Mus. Nat. Hist., New York 41: 67 (1888)) and then republished by Peck as a new species, Inocybe vatricosoides.

Basionym: Inocybe vatricosoides Peck (1910)

Types: UNITED STATES: New York: Ulster County (approx. 41.8586°N, 74.3118°W, alt. approx. 300 m a.s.l.) on boggy soil under Salix sp., Sep. 1887, C.H. Peck (Holotype. herbarium acc. no. NYS-F-003336, HJB1000541).

Original diagnosis: Pileus tenuis, convexus, deinde subplanus, dum humidus subviscidus. obtusus subumbonatusve. margine velo abundante albido arachnoideo fibrillosus, albidus saepe centro. rufescens. carne albida, odore Raphani; lamellae confertae. late sinuatae, adnatae, albidae deinde fusco-ferrugineae, acie albae crenulatae; stipes aequalis, flexuosus, saepe basi curvatus. farctus fistulosusve. sericeo-fibrillosus, aliquando infra squamulis albis floccosis ornnatus, albidus vel griseus; sporae eilipsoideae. levcs. 10-12 x 6-8 µ.

English translation: Provided by Peck: Pileus thin, convex becoming nearly plane, slightly viscid when moist, obtuse or subumbonate, fibrillose on the margin from the abundant whitish webby veil, whitish. often reddish in the center, flesh whitish, odor like that of radishes; lamellae close. broadly sinuate. adnate with a decurrent tooth, whitish becoming brownish ferruginous, white crenulate on the edge; stem equal, flexuous usually curved at the base, stuffed or hollow, silky fibrillose, whitish or grayish, sometimes with whitish floccose scales toward the base; spores ellipsoid, even. 10-12 x 6-8 µ. Pileus 2-3 cm broad; stem 2.5-5 cm long, 2-6 mm thick. Damp ground under willows. Ulster co. [Catskill Mountains] September. This species is closely allied to Inocybe vatricosa Fr. to which it was referred in New York State Museum Report 41, page 67, but from which it is here separated because of its well developed webby veil, its radishlike odor, its adnate lamellae, its silky fibrillose stem and its larger spores.

Commentary: As pointed out by Peck in the diagnosis, this material was originally collected in 1887 and described as Inocybe vatricosa but was eventually separated from that species on account of the radish-like odor as well as the veil characteristics. With the small ellipsoid to ovoid pale yellow to grey yellow spores and the ventricose to lageniform cheilocystidia this species belongs within Hebeloma sect. Hebeloma. Morphologically H. vatricosoides is closely related to H. excedens, H. mesophaeum and H. pascuense. Based on locality and habitat as well as the paleness of the spores this is most likely to be H. excedens, with which it is synonymized above. Unfortunately, we were unable to generate a sequence from this material. Hence, based on morphological analysis, biogeography and habitat, this is: = Hebeloma excedens (Peck) Sacc.
