Hebeloma ambustiterranum

Ciri dan struktur

The small ellipsoid, non-dextrinoid, almost smooth basidiospores (on average 8.0–10.2 × 5.6–6.5 µm) and at least 50 full length lamellae distinguish this species from all other known North American Hebeloma species and the ITS sequence differentiates this species from all other known species, worldwide. Pileus (12) 16–45 (52) mm diameter, usually umbonate or subumbonate, rarely convex or applanate; margin usually entire, sometimes involute particularly when young, often with remains of the universal veil, occasionally spotting, not hygrophanous; usually almost unicolored with color at center usually cream to ochraceous or clay-buff but may occasionally be darker, honey to sepia or umber, usually a little paler at the margin. Lamellae emarginate, white, cream to brown, with a weak white fimbriate edge sometimes visible and without droplets, number of full-length lamellae 50–74. Stipe (23) 24–60 (75) mm long, 3–8 (10) mm diameter at median, cylindrical, surface cream, ivory to pale brown but occasionally discoloring from the base upwards, sometimes strongly, fibrillose, at apex pruinose; base with white mycelium. Partial veil present on young specimens, whitish at first, before basidiospores mature, and often clear fibrils remaining on the stipe and pileus. Context in pileus white to cream, firm, in stipe stuffed, becoming hollow with age; taste not recorded, smell occasionally odorless but usually raphanoid, sometimes strongly so or with cacao components. Spore deposit color clay-buff. Basidiospores based on n = 146 spores of the holotype, 5% to 95% percentile range 7.7–9.8 × 5.5–7.0 µm, with median 8.9 × 5.9 µm and av. 8.9 × 6.0 µm with S.D. length 0.68 µm and width 0.44 µm; Q value 5% to 95% percentile range 1.25–1.63, with median 1.48 and av. 1.47 with S.D. 0.11; spore size based on 33 collections medians 7.8–10.3 × 5.5–6.4 µm and av. 8.0–10.2 × 5.6–6.5 µm with av.

Habitat dan peran ekologis

In temperate coniferous woodlands on burnt ground with Pinus and Quercus. Growth habit usually scattered, rarely solitary or caespitose. To date, all collections of Hebeloma ambustiterranum recorded from Mexico at latitudes between 19°N and 20°N and altitudes above 2000 m.
