4E3C6F166E78FF87FAA24DB1FB48FD74.taxon	description	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. Type: — USA. Florida: Miami, Matheson Hammock, alt. 1 m, on angiosperm log, 19 April 2009, J Vlasák 0904 / 20 (holotype, BJFC!; isotype JV!). Etymology: — Americana (Lat.) referring to distribution of the species in America. 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. 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. 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. 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. 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). Type of rot: — Brown rot. Additional specimens examined: — USA.
