Thaxterogaster melleicarneus

Ciri dan struktur

Thaxterogaster melleicarneus produces medium-sized fruit bodies with a cap (pileus) 4–10 cm broad, initially hemispherical to convex with the margin turned inwards and later expanding. The surface may appear silvery-silky from fine veil remnants and ranges in colour from cream through pale yellow-brown or honey brown to grey-brown, often showing darker hygrophanous streaks or zones (areas that deepen in hue as they lose moisture) near the margin. The lamellae are emarginate (notched where they meet the stipe), crowded, pale greyish-white when young and turning pale greyish-brown with age. The stipe is 5–7 (rarely up to 9) cm long and 1.2–2 cm thick at the apex, widening to 2–3 cm at the base; it is club-shaped (clavate) or bears a faintly marginate bulb, short and robust, and remains white. A very sparse white universal veil may persist at the stipe base. The flesh (context) in the pileus is pale yellow-brown with marbled, flesh-coloured hygrophanous patches, while the stipe context is white. No distinct odour has been recorded. Microscopically, spores measure 7.9–9.5 by 4.3–5.2 μm (average 8.6–8.9 by 4.7–4.8 μm). Their shape ranges from almond-shaped to fusoid, with a low suprahilar depression and a blunt apex; surfaces are densely to coarsely verrucose (warted) and stain slightly to moderately dextrinoid (reddish-brown) in Melzer's reagent. Basidia are four-spored, clavate, 25–31 by 7–8 μm, often containing granular guttules (oil droplets). The lamellar trama comprises pale yellow, smooth hyphae, while hyphae at the stipe apex are very pale yellowish and smooth without coloured guttules.

Habitat dan peran ekologis

Thaxterogaster melleicarneus grows in warm‐climate deciduous woodlands on calcareous soils, often where near-shore sandy shell beds enrich the substrate. It is currently known from Hiiumaa in Estonia and from southern Norway. In Norway (Aust-Agder, Grimstad–Fevik), fruit bodies have been found on rich, sandy soils beneath mixed stands of oak, beech and planted larch, suggesting a preference for humus-rich, shell-bed influenced terrain.

Reproduksi

Microscopically, spores measure 7.9–9.5 by 4.3–5.2 μm (average 8.6–8.9 by 4.7–4.8 μm). Their shape ranges from almond-shaped to fusoid, with a low suprahilar depression and a blunt apex; surfaces are densely to coarsely verrucose (warted) and stain slightly to moderately dextrinoid (reddish-brown) in Melzer's reagent. Basidia are four-spored, clavate, 25–31 by 7–8 μm, often containing granular guttules (oil droplets). The lamellar trama comprises pale yellow, smooth hyphae, while hyphae at the stipe apex are very pale yellowish and smooth without coloured guttules. The pileipellis has a gelatinous epicutis of erect, sinuous hyphae 3–8 μm wide, thin-walled and very finely incrusted, over a hypoderm of pale yellowish-brown cells with few incrusted hyphae and small brown spots deeper in the cap surface.
