Polyozellus alnophilus

Ciri dan struktur

Basidiomata annual, resupinate, membranaceous, effused. Mature parts continuous, with a soft cottony texture. Hymenium smooth; blue grey, sometimes with a slightly brown hue. Immature parts discontinuous, byssoid, with a soft cottony texture. Subhymenium and hymenium of immature parts pale blue grey to blue grey. Subiculum thin to well developed, loose, fibrous, orange brown; often forms the outer edge of basidiomata, extending noticeably beyond the hymenium. All characters recorded in dried state. Hyphal cords lacking, but loose bundles of subicular hyphae sometimes present. Hyphal system monomitic, clamp connections and reaction in Melzer’s reagent absent from all hyphae. Subicular hyphae noticeably long and straight, thick-walled; forming a loose tissue. Individual hyphae 4.0–5.0 (–5.1) μm wide, with a mean width of 4.5 μm; orange brown to dark brown in KOH and orange to orange brown in water. Subhymenial hyphae often somewhat sinuous, thin to thick-walled; forming a rather dense tissue. Individual hyphae (3.2–) 3.4–5 (–5.6) μm wide, with a mean width of 4.1 μm; hyaline to pale orange brown in KOH, blue green in the presence of air; pale green in water, with strongly granular contents. Encrustation not seen. Basidia with four slightly curved sterigmata, occasionally two-sterigmate; clavate to narrowly clavate, sometimes clavopedunculate, thin-walled, with one-three slight constrictions. Dimensions: (66–) 67–93 (–100) × (11.2–) 11.3–14.2 (–15.0) μm; mean dimensions: 83 × 12.8 μm. Sterigmata (9.5–) 11–14.5 (–14.8) μm long, with a mean length of 8.6 μm. Colours and reactions the same as for the subhymenial hyphae, but in addition often with granular contents in KOH.

Habitat dan peran ekologis

The only specimens recorded to date of P. alnophila is the type collection and one other collection from the same locality, which is a mature and, at the collection site pure, stand of Alnus incana on clay soil with intermediate pH. In addition, UNITE sequence metadata show that the species forms ectomycorrhiza with at least Alnus mandschurica (Kõljalg et al. 2005, Nilsson et al. 2019). Basidiomata encountered in: Norway. Soil or root tip samples confirm presence also in: China.
