Stephanospora mayana

Ciri dan struktur

Stephanospora mayana can be distinguished by the yellowish net-like pileus, the variable spore size (8.0–17.0 × 6.0–11.0 µm), thin pileus (21.0–40.0 µm) and the ecological association to lowland forest and pine savanna with H. campechianum, G. floribundum, C. diversifolia, M. brownei, and P. caribaea. Basidiomata hypogeous to subhypogeous, scattered, 3.0–15 × 2.0–6.0 mm, globose to subglobose, without rizomorphs or stipe. Pileus yellowish to slightly orange (5A6-30A3-6), bruising pale orange when touched, wet to dry, sometimes net-like, dehiscent, showing locules inside. Hymenophore brittle, grayish (5C4), with empty rounded to angular locules, reaching 0.5 mm long, sometimes with white short and slender hyphae projecting from pileus to locules, trama sometimes orange (5A7-5B7), odour and taste strongly fruity. Pileus 21.0–40.0 µm thick, composed of loosely interwoven, slender to inflated hyphae, 1.7–4.2 µm in diameter, orange to pale orange-yellow in KOH, thin-walled. Hymenophoral trama irregular, 62.0–100.0 µm wide, composed of irregular, globose, isodiametric and compacted hyphae, 13.5–26.3 µm in diameter, hyaline to slightly yellowish in KOH, thin-walled. Basidia 24.2–30.5 × 9.5–11.1 µm, clavate to subclavate, hyaline in KOH, guttulate, 2-spored, with long sterigmata, reaching 7 µm long, thin-walled, collapsing after basidiospore development. Basidiospores (8.0–) 10.0–16.0 (–17.0) × (6.0–) 8.5–10.5 (–11.0) µm (L = 12.10, W = 9.31, Q = 1.30, N = 90) ellipsoid to subglobose, with truncate to acute spines projecting 2.0 µm long, forming ridges reaching 3.5 µm high, sometimes coalescing, with a complete to partial corona 4.0–6.0 × 1.0–2.5 µm long, sometimes with 2–4 projecting spines, 1.5 µm long, with hilar appendage conspicuous, reaching 3 µm long, bright yellowish in KOH, orange in Meltzer reagent, with greenish to yellowish cell wall, 1.5–2.0 µm thick.
