Holotype.
USA. Florida: Miami, Matheson Hammock, 19 Apr 2009, on living tree of Krugiodendron ferreum , JV0904/1 (Holotype in PRM, isotype in JV and BJFC).
Etymology.
Krugiodendri (Lat.): referring to the host tree genus Krugiodendron .
Description.
Basidiocarps perennial, sessile, solitary, without odor or taste, woody hard, light in weight when dry, projecting up to 10 cm, 15 cm wide and 6 cm thick at center. Pileal surface dark grey, crusted, concentrically sulcate with narrow zones, cracked; margin cinnamon-buff, obtuse. Pore surface grayish brown, shining; sterile margin distinct, yellowish brown, up to 3 mm wide; pores circular, 7-9 per mm; dissepiments thick, entire. Context dark brown, woody hard, up to 5 mm thick. Tubes yellowish brown, woody hard, up to 5.5 cm thick, tube layers distinctly stratified with intermittent context layers, individual tube layer up to 3 mm thick.
Hyphal structure.
Hyphal system dimitic; generative hyphae simple septate; skeletal hyphae dominant; tissue darkening but otherwise unchanged in KOH.
Context.
Generative hyphae pale yellowish, slightly thick-walled, rarely branched, occasionally simple septate, 2-3 µm in diam; skeletal hyphae dominant, yellow to brown, thick-walled with a wide to narrow lumen, unbranched, aseptate, interwoven, 3-4 µm in diam.
Tubes.
Generative hyphae hyaline to pale yellow, thin- to slightly thick-walled, rarely branched, frequently simple septate, 1.5-3 µm in diam; skeletal hyphae dominant, pale yellow, thick-walled with a wide to narrow lumen, unbranched, aseptate, loosely interwoven, 2-3 µm in diam. Setae absent; cystidia and cystidioles absent; hymenium collapsed, basidia and basidioles not oberved.
Spores.
Basidiospores subglobose, yellowish brown, thick-walled, smooth, some collapsed when mature, IKI–, CB–, (4.0 –)4.3–5.0(– 5.1) × (3.7 –)4.0–4.5(– 4.8) μm, L = 4.60 μm, W = 4.21 μm, Q = 1.08-1.09 (n = 60/2).
