L. Han, Vlasak & B. K. Cui JV 2015	<div><p>Daedalea americana M.L. Han, Vlasák &amp; B.K. Cui, sp. nov. (Figs. 1–2)</p> <p>MycoBank: MB 810872</p> <p>Daedalea americana is characterized by annual and pileate basidiocarps, grayish brown with brown to cinnamon brown band and concentrically zonate pileal surface when fresh, cream to clay-pink pore surface, circular to angular pores (4–5 per mm) and ellipsoid basidiospores measured as 4.0–5.1 × 2.1–3.0 μm.</p> <p>Type:— USA. Florida: Miami, Matheson Hammock, alt. 1 m, on angiosperm log, 19 April 2009, J Vlasák 0904/20 (holotype, BJFC!; isotype JV!).</p> <p>Etymology:— Americana (Lat.) referring to distribution of the species in America.</p> <p>Basidiocarps: —Basidiocarps annual, pileate, confluent, corky, without odor or taste when fresh, hard corky and light in weight when dry; pileus applanate to slightly concave, semicircular, flabelliform to dimidiate, projecting up to 2.5 cm, 4.5 cm wide and 1.1 cm thick at base; pileal surface grayish brown with brown to cinnamon brown band when fresh, becoming flesh-pink to cream to brown upon drying, glabrous to tuberculate, concentrically zonate and radially streaked; margin cream to pale brown when fresh, becoming cream to clay-pink with age, acute; pore surface cream to clay-pink; sterile margin indistinct; pores circular to angular, 4–5 per mm; dissepiments thin to thick, entire; context cream to clay-buff, corky, up to 9 mm thick; tubes concolorous with pore surface, corky, up to 2 mm long.</p> <p>Hyphal structure:— Hyphal system trimitic; generative hyphae bearing clamp connections; skeletal hyphae IKI–, CB–; contextual tissues becoming fawn first, then fading into grayish brown in KOH, tramal tissues becoming dark brown firstly, then fading into grayish brown in KOH.</p> <p>Context: —Generative hyphae infrequent, hyaline, thin-walled, moderately branched, 2–3.5 μm in diam.; skeletal hyphae dominant, hyaline to pale yellowish, thick-walled with a wide to moderate lumen, unbranched, flexuous, 2–4 μm in diam., interwoven; binding hyphae hyaline to pale yellowish, thick-walled with a narrow lumen to subsolid, flexuous, frequently branched, 2–3 μm in diam.</p> <p>Tubes: —Generative hyphae infrequent, hyaline, thin-walled, moderately branched, 2–3 μm in diam.; skeletal hyphae dominant, hyaline to pale yellowish, thick-walled with a wide to moderate lumen, unbranched, flexuous, 2–3.5 μm in diam., interwoven; binding hyphae hyaline to pale yellowish, thick-walled with a narrow lumen to subsolid, flexuous, frequently branched, 1.5–3 μm in diam. Cystidia absent, sometimes skeletal hyphae penetrated into the hymenium, but not forming typical catahymenium; cystidioles present, fusoid, sometimes with simple septa near to tips, hyaline, thin-walled, 9–17 × 3–3.5 μm. Basidia clavate, bearing four sterigmata and a basal clamp connection, 11–15 × 4–5 μm; basidioles dominant, in shape similar to basidia, but smaller.</p> <p>Spores: —Basidiospores ellipsoid, tapering at apiculus, hyaline, thin-walled, smooth, IKI–, CB–, 4.0–5.1(–5.5) × (2.0–)2.1–3.0(–3.1) μm, L = 4.55 μm, W = 2.65 μm, Q = 1.70–1.74 (n = 40/2).</p> <p>Type of rot:—Brown rot.</p> <p>Additional specimens examined: — USA.
