Original diagnosis: Pileus 1.5-3 cm latus, obtusus demum convexus vel planus, glaber, vel ad marginem leviter fibrillosus, subviscidus, ad centrum fuscobrunneus, tarde pallidior. Context fragilis, fragrans, sapor mitis. Lamellae subdistantes, latae demum ventricosae, cinnamomeoargillaceae. Stipes 2-3.5 cm longus, 3-4.5 mm crassus, fragilis, cinereobrunneus, brunnescens; velum cinereo-argillaceum. Sporae 10-15 x 6-7 μm, non dextrinoideae; inequilaterales, Cheilocystidia 42-73 x 4-6 μm, ~ cylindrica vel filamentosa, vel 38-67 x 6-12 x 4-6 μm, fusoide ventricosa, hyalina.

English translation: Pileus 1.5-3 cm broad, obtuse then convex or applanate, glabrous, or slightly fibrillose on the margin, slightly viscid, dark brown in the centre, paler in age. Context fragile, fragrant, taste mild. Lamellae subdistant, broad, then ventricose, cinnamon-argillaceous. Stipe 2-3.5 cm long, 3-4.5 mm thick, fragile, greyish-brown, becoming brown; veil greyish-argillaceous. Spores 10-15 x 6.7 μm, indextrinoid; inequilateral. Cheilocystidia 42-73 x 4.6 μm, more or less cylindrical or filamentous or 38-67 x 6-12 x 4-6 μm, fusoid-ventricose, hyaline.

Commentary: Unfortunately we have been unable to generate any DNA sequence data. However, based on morphological and habitat analysis this is: = Hebeloma palustre Peck.

Full name: Hebeloma fragrans var. intermedium A.H. Sm., V.S. Evenson & Mitchel (1983)

Taxonomic status: Heterotypic synonym of H. discomorbidum
Types: UNITED STATES: Colorado: Pitkin County, Burnt Mountain (approx. 39.2129°N, 106.9196°W, alt. approx. 2500 m a.s.l.) in subalpine woodland under Picea sp., 30 Aug. 1980, A.H. Smith (90636) (Holotype. herbarium acc. no. MICH 10742, HJB1000362).

Original diagnosis: Pileus 2-4.5 cm latus, convexus demum planus, subviscidus, rufobrunneus demum sordide fulvus; odor fragrans, gustus amarus. Lamellae latae demum ventricosae, confertae, subfulvae. Stipes 3-6 cm longus, + 4 mm crassus, brunnescens; velum pallide subochraceum. Sporae 11-14 x 6-7 μm, dextrinoideae. Cheilocystidia versiforme: (1) fusoid-ventricosa et 43-70 x 7-12 x 3.5-5 μm; (2) filamentosa et 28 -70 x 3-6 μm; (3) rare subsaccata.

English translation: Pileus 2-4.5 cm broad, convex then applanate, slightly viscid, red-brown, later dingy fulvous; smell fragrant, taste bitter. Lamellae broad then ventricose, crowded, almost fulvous. Spores 3-6 cm long, about 4 mm thick, discolouring brown; veil pale ochraceous. Spores 11-14 x 6-7 μm, dextrinoid. Cheilocystidia versiform: (1) fusoid-ventricose and 43-70 x 7-12 x 6-7 μm; (2) filamentous and 28-70 x 3-6 μm; (3) rarely subsaccate.

Commentary: We have examined both the holotype and a topotype collected on the same day and determined by Smith and Evenson as H. fragrans var. intermedium (HJB15793). While we were unable to generate any molecular sequence, based on the morphological study of both these collections, this is: = Hebeloma palustre Peck.
