Basidiocarps annual, laterally to centrally stipitate, soli- tary. Pileus reniform to semicircular, circular in centrally stipitate basidiocarps, applanate to conchate, 2–7 cm from the base to margin, 2.5–13 cm wide, up to 10 mm thick; surface glabrous, cream to brownish orange (10YR5–8/4– 9), covered with appressed scales, scales often lost with age, then sordid white to cream, smooth, azonate; margin acute, entire. Stipe cylindrical, up to 1 cm long, up to 1.5 cm in diam. Context fleshy-tough in fresh condition, corky or brittle in dried condition, white, up to 6 mm thick. Pore surface white, cream to grayish orange (10YR8–9/4), pores radially elongated, (0.5–)0.7–7 × 0.5–3 mm, dissepiments thin, entire to slightly lacerate. Tubes concolorous with the pore surface, up to 6 mm deep. Hyphal system dimitic with generative hyphae and skeletal-binding hyphae. Contextual generative hyphae thin-walled, hyaline, with clamp connec- tions, up to 4.5 μm in diam. Contextual skeletal-binding hyphae usually thick-walled, occasionally branched, interwo- ven, hyaline, non-dextrinoid, 3.5–5 μm in diam. at basal stalk. Tramal generative hyphae same as in context but more abun- dant. Tramal skeletal-binding hyphae thick-walled to solid, occasionally branched, moderately interwoven, hyaline, non- dextrinoid, 3.5–6 μm in diam. at basal, taper to 1.5 μm in diam. at apex. Pileipellis present as cutis composed of hyaline to brown, parallel and agglutinated generative hyphae cover- ing context mainly composed of non-agglutinated and inter- woven skeletal-binding hypae. Basidia clavate, 4-sterigmate, 17.5–26 × 4–7 μm. Basidiospores cylindrical, hyaline, non- dextrinoid, (6.5–)7–10(−10.5) × 2.5–4 μm, L 0 8.29 μm, W 0 3.01 μm, R02.1–4.3, r03.01 (n0150/4).
Distribution Widely distributed in temperate to boreal areas of the Northern Hemisphere. Known from North America (Boulet 2003; Gilbertson and Ryvarden 1987), Central and Southern Europe (Bernicchia 2005; Ryvarden and Gilbertson 1994), East Asia (Núñez and Ryvarden 1995a, 2001; Dai 2012). Remarks Neofavolus alveolaris is variable in the color of the pileus surface and the size of basidiocarps. This species is well characterized by the large sized alveoloid pores and distinct scales on the pileus surface that can be lost in old specimens.
