Holotype.

USA. Florida: Collier-Seminole State Park, 28 Aug 2010, on Conocarpus erectus , JV 1008/60 (BJFC).

Etymology.

Mangrovei (Lat.): referring to the species growing in mangrove. Basidiomata annual, resupinate, inseparable, without odor or taste when fresh, woody hard on drying, up to 30 cm long, 7 cm wide and 5 mm thick at center. Pore surface ash-gray to bluish gray when fresh, becomes pale clay-buff to pale brown and uncracked when dry; pores angular, 3-5 per mm; dissepiments thin, more or less entire to slightly lacerate; tubes woody hard, dark brown, up to 5 mm long. Subiculum very thin to almost lacking.

Hyphal structure.

Hyphal system monomitic; generative hyphae simple septate; tissue darkening but otherwise unchanged in KOH.

Tubes.

Generative hyphae hyaline to pale yellowish, thin- to thick-walled with a wide lumen, occasionally branched, frequently simple septate, interwoven, 1.5-3 mm in diam; setae absent; cystidioles absent; basidia barrel-shaped, with four sterigmata and a simple basal septum, 12-15 × 4-6 μm; basidioles barrel-shaped to pyriform, slightly smaller than basidia in size.

Spores.

Basidiospores broadly ellipsoid, yellowish-brown, thick-walled, smooth, IKI–, CB+, (5 –)5.5–6(– 6.3) × (4 –)4.2–4.8(– 5) μm, L = 5.82 μm, W = 4.47 μm, Q = 1.26-1.31 (n = 60/2).
