Type and marine species:

Haloaleurodiscus mangrovei N. Maek., Suhara & K. Kinjo, Mycological Research 109 (7): 827 (2005)

Saprobic, Sexual morph: 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 mm thick; margin concolorous with the hymenial surface, determinate, in vertical section subhyaline, membranous with a basal layer 15–40 mm thick, sometimes containing numerous crystals. Hyphal system monomitic, hyphae 1.5–3 mm in diam., smooth, thin-walled, but sometimes thickened to 1 mm in the basal layer, no doseseptate. Gloeocystidia numerous, mostly embedded but occasionally projecting up to 15 mm beyond the hymenial surface, tubular, sinuous, 80–190 x 5–7.5 mm, smooth, thin- to thick-walled (up to 1 mm), 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 x 9–10.5 mm, with a basal clamp, producing four sterigmata. Basidiospores narrowly ellipsoid to cylindrical, 13.5– 15.5 x 8–9.5 mm, usually finely warted, thin- to slightly thick-walled (to 0.5 mm), amyloid. Asexual morph: Undetermined.

NOTES: This species is characterized by having resupinate basidioma, nodose–septate hyphae, sulphoaldehyde–positive gloeocystidia, dendrohyphidia and amyloid basidiospores with minute warts. It shares many features with Aleurodiscus s. lat., but sequence data show it is a unique lineage basal to the Peniophorales’ clade. Haloaleurodiscus mangrovei differs from other marine basidiomycetes morphologically and phylogenetically which group in the eugarics clade (Hibbett & Binder 2001, Jones et al. 2015).
