Hebeloma magnicystidiatum

Ciri dan struktur

The amygdaloid, non-dextrinoid, rather strongly ornamented spores with average Q value less than 1.6 and the capitate-stipitate cheilocystidia with average width at the apex greater than 9.5 µm distinguish this species from all other known Hebeloma species. Pileus 19–26 mm diameter, convex, surface dry, finely tomentose, cuticle separable, reddish yellow to brown in the center, and pale orange towards the margin. Lamellae emarginate, white, cream to orange brown as the spores mature, with a white fimbriate edge, and about 60 full-length lamellae. Stipe 10–21 mm long, 4–6 mm diameter at median, cylindrical, surface whitish but discoloring brown from the base upwards, with age or handling, fibrillose, at apex pruinose. Context in pileus white to cream, firm, in stipe stuffed, initially white to cream but becoming brown with age and handling, becoming hollow with age; taste fungal to sweet, smell raphanoid. Spore deposit not recorded. Basidiospores based on n = 44 spores of the holotype, 5% to 95% percentile range 9.7–11.6 × 6.4–7.6 µm, with median 10.5 × 7.0 µm and av. 10.5 × 7.0 µm with S.D. length 0.62 µm and width 0.42 µm; Q value 5% to 95% percentile range 1.40–1.62, with median 1.49 and av. 1.50 with S.D. 0.07; amygdaloid, often limoniform, with small apiculus and rounded apically, often subacute to acute, with a distinct thinning of the apical wall and sometimes a clearly visible papilla, not guttulate, usually rather strongly ornamented, ornamentation visible even without immersion, with perispore at most somewhat loosening in a few spores, an indistinct brownish tint in Melzer’s reagent (O3; P1; D1); yellow-brown in KOH.
