Ciri dan struktur
The short clavate-ventricose cheilocystidia, with average apical width less 6.5 µm, the small (on average less than 10 × 5.5 µm), weakly ornamented but rather strongly dextrinoid basidiospores and the whitish to cream or buff color of the pileus, differentiate this species from other Hebeloma species. Pileus (22) 32–38 (47) mm diameter, convex, often applanate, occasionally umbonate; margin smooth, often involute, particularly when young, occasionally eroded, not hygrophanous; usually almost unicolored, usually cream or buff, sometimes slightly paler towards margin. Lamellae often adnate or adnexed, occasionally emarginate, depth up to 4 mm, white, cream to brown, with white fimbriate edge but without droplets on the lamella edge, number of full-length lamellae 70–80. Stipe (31) 37–46 (48) mm long, (5) 7–8 (10) mm diameter at median, usually cylindrical but sometimes with a clavate base, surface cream, ivory, not discoloring, fibrillose, pruinose, particularly towards apex; base with white mycelium. Context in pileus and stipe white to cream, firm, in stipe stuffed; taste not recorded, smell earthy. Spore deposit color not recorded. Basidiospores based on n = 64 spores of the holotype, 5% to 95% percentile range 8.6–10.5 × 4.9–5.7 µm, with median 9.4 × 5.3 µm and av. 9.5 × 5.3 µm with S.D. length 0.57 µm and width 0.26 µm; Q value 5% to 95% percentile range 1.64–1.95, with median 1.79 and av. 1.78 with S.D. 0.10; spore size based on four collections medians 9.1–9.5 × 5.3–5.6 µm and av. 9.1–9.5 × 5.3–5.5 µm with av. S.D. length 0.50 µm and width 0.30 µm, av. Q 1.65–1.78, amygdaloid, occasionally limoniform, with small apiculus and rounded apically, often subacute, with a distinct thinning of the apical wall and sometimes a papilla, usually guttulate with one or sometimes more oily drops, at most weakly ornamented (ornamentation only visible under immersion), with a perispore hardly loosening, rather strongly dextrinoid, becoming medium reddish brown in Melzer’s reagent (O1/2; P0; D3); yellow brown in KOH.
Habitat dan peran ekologis
In deciduous or mixed woodlands apparently associated with Quercus or Pseudotsuga. Growth habit mainly caespitose, sometimes with a few scattered basidiomes. To date, all collections of Hebeloma cohaerens recorded from Tlaxcala at altitudes of 2600 m or more.
