ED7287EBFF8B913F73F4FD6AFE20FB8B.taxon	description	Description: — Basidiomata effused, easily detachable from the substrate, white (in young parts) to beige (cream 5 E) (in old parts), KOH –. Hymenophore smooth, membranous, cracked on drying, subiculum whitish (2 B). Margin slightly fimbriate, hyphae in margin 3.5 – 4 μm diam. Hyphal system monomitic, hyphae clamped; hyphae of subhymenium, thin-walled, hyaline, 4 – 6 μm diam., hyphae of subiculum thin-walled, hyaline, (5 –) 6.5 – 10 (– 16) μm diam. Rhizomorph-like bundles of hyphae occur in subiculum, extending into the substrate, composed of thin-walled 6 – 16 μm wide hyphae with occasional inflations up to 18 μm. Scattered vesicles occur on short side-branches from basal hyphae, ca 40 × 20 μm, thin-walled, with smooth, homogenous contents. Some basal hyphae more or less encrusted by rhomboidal crystals, scattered crystals occur throughout the basidioma. Basidia cylindrical, (11 –) 12 – 16 (– 20 × 4 – 5 (– 6.5) μm, producing four sterigmata. Basidiospores elliptic 4 – 5 (– 6) × 2 – 2.5 (– 3) μm, smooth, thin-walled, with guttulae and distinct apiculus, IKI –. Substrate: — decaying hardwood.	en	Chikowski, Renata Dos Santos, Larsson, Karl-Henrik, Gibertoni, Tatiana Baptista (2016): Ceraceomyces atlanticus (Amylocorticiales, Basidiomycota), a new species from the Atlantic Rain Forest, Brazil.

ED7287EBFF8B913F73F4FD6AFE20FB8B.taxon	discussion	Remarks: — Ceraceomyces atlanticus differs from both C. tessulatus and C. subapiculatus by distinctly shorter basidia (11 – 20 μm versus 25 – 35 μm) and smaller spores [4 – 6 μm long versus 6 – 8 (– 10) μm]. Ceraceomyces serpens, which according to molecular data is not a member of Ceraceomyces sensu stricto, is reported from Brazil. It differs by a merulioid hymenium when fresh and by narrower hyphae in the subhymenium (2 – 4 μm) and in the subiculum (2 – 4.5 μm).	en	Chikowski, Renata Dos Santos, Larsson, Karl-Henrik, Gibertoni, Tatiana Baptista (2016): Ceraceomyces atlanticus (Amylocorticiales, Basidiomycota), a new species from the Atlantic Rain Forest, Brazil.
