description
Description. Basidioma — Annual to biennial, resupinate, soft when fresh and rather tough, soft-corky after drying, confluent and widely effused covering extended under-surface of decaying logs, 0.8 – 2.0 mm thick at the centre; pore surface white to cream when fresh, becoming yellowish to buff when dry; sterile margin indistinct, cottony, white, thinning-out; pores very small, roundish, (5) 6 – 8 (10) per mm (n = 273 / 13); dissepiments thin, entire to slightly lacerate; subiculum very thin, cottony, concolorous with the tube layer; tubes concolorous with the poroid surface, up to 2 mm long. Hyphal system dimitic in all parts of the basidioma; generative hyphae smooth, without encrustations, septa with clamp connections; skeletal hyphae not reacting with Cotton Blue, Melzer’s reagent or KOH. Subiculum — Hyphae interwoven, skeletal hyphae dominating, skeletals (1.7) 2 – 3.5 (4.0) μm in diameter, rosette-like crystal clusters rare to common. Tubes — Hyphae subparallel to moderately interwoven. Generative hyphae, thin to slightly thick-walled, poorly branched, 1.7 – 3.0 μm in diameter. Skeletal hyphae, thick-walled to subsolid, hyaline, rarely branched, flexuous, 1.7 – 3.5 μm in diameter, with scattered swellings up to 7 μm. Dissepiment edges with both generative and skeletal hyphae that often bear a swollen, capitate apex, generative hyphae sometimes covered by a mucous droplet, rosette-like crystals frequent in mature basidiomata. Cystidioles seldom to abundant, fusoid, thin-walled, hyaline, basally swollen, with hyphoid neck and mostly obtuse or capitate tip, some bearing crystals at apex (asterocystidia), a few modified as halocystidia were also observed, (9.3) 12.4 – 19.9 (25.0) × (2.2) 2.8 – 4.0 (5.3) μm (n = 125 / 15). Basidia barrel-shaped to somewhat short-clavate, with four sterigmata and a basal clamp, (6.2) 6.8 – 9.9 (14.6) × (3.1) 3.8 – 4.7 (5.6) μm (n = 185 / 15); basidioles barrel-shaped, slightly shorter than the basidia. Basidiospores — Cylindrical, moderately curved to lunate, thin-walled, hyaline, smooth, negative in Melzer’s reagent, acyanophilous, (3.0) 3.4 – 3.9 (4.3) × (1.2) 1.4 – 1.6 (1.8) μm, Average = 3.6 × 1.5 μm, Q = (1.95) 2.24 – 2.60 (3.08) Q AV = 2.41 (n = 399 / 15).

distribution
Distribution and hosts. The species is reported from Mediterranean Europe (e. g. Portugal, Spain, France, Italy, Croatia and Greece), Germany, Slovakia, Poland, Estonia, Sweden, Belarus, Russia, as well as from Armenia, Georgia, Iran, Kazakhstan, China, USA and Canada (Niemela ̈ and Dai 1997; Ghobad-Nejhad 2011; Bernicchia et al. 2020; Liu et al. 2022; this work). It occurs on various broadleaved trees of (Alnus, Eucalyptus, Fagus, Populus, Quercus, Sorbus and Ulmus), as well as on coniferous trees, i. e. Picea, Pinus (P. halepensis, P. nigra ssp. laricio, P. pinaster, P. sylvestris) or Juniperus and on Abies cephalonica (this work).
