Haloaleurodiscus mangrovei
Haloaleurodiscus mangrovei N. Maek., Suhara & K. Kinjo 2005, in Maekawa et al., Mycological research, 109(7), 825-832 (2005)
Etymology: From mangrove, referring to the habitat of this species.
Diagnosis: Basidiomata annual, resupinate, occurring as small patches, sometimes confluent, pinkish cream, ‘Salmon’ to ‘Saffron’ when fresh, white, pale dull-cream to grayish white when dry, 300–600 µm thick; margin concolorous with the hymenial surface, determinated, in vertical section subhyaline, membranous with a basal layer; basal layer 15–40 µm thick, sometimes containing numerous crystals. Hyphal system monomitic; hyphae 1.5–3 µm in diam, smooth, thin-walled, but sometimes thickened to 1 µm in the basal layer, nodoseseptate. Gloeocystidia numerous, mostly embedded but occasionally projecting up to 15 mm beyond the hymenial surface, tubular, sinuous, 80–190×5–7.5 µm, smooth, thin- to thick-walled (up to 1 µm), with a basal clamp, weakly positive to sulphobenzaldehyde (SA+). Dendrohyphidia occurring in the hymenium, several branched at the upper part, with a basal clamp. Basidia narrowly clavate, sometimes sinuous, 65–75×9– 10.5 µm, with a basal clamp, producing four sterigmata. Basidiospores narrowly ellipsoid to cylindrical, 13.5–15.5×8–9.5 µm, usually fine-warted, thin- to slightly thick-walled (to 0.5 µm), amyloid.
