Assessment Notes

Taxonomic notes

Auricularia brasiliana was segregated from the complex A. mesenterica (currently restricted to Europe) and is characterized by resupinate to effused-reflexed basidiomata, gelatinous when fresh, solitary, or caespitose, pileus free lobed, margin undulate, upper surface usually tomentum, distinctly and concentrically zoned with wide whitish zones and thin black bands; hymenophore surface venose with folds, greyish brown to vinaceous brow when fresh and dark greyish blue to blackish blue when dry. It differs from other similar species (A. mesenterica and A. orientalis) by inflated hyphae up to 13 μm in diam. in KOH, shorter basidia 30–47×3–5 μm (Wu et al. 2015).
