Description: Basidiocarps perennial, resupinate to effused-reflexed, extending up to 1 m and up to 2 mm thick, hymenium light grey to cream, tuberculate, cracking with age, surface towards the substrate black. Characteristic smell of coconut. Basidiospores ellipsoid, 4.5-5.5 x 2.5-3 µm, hyaline, gloeocystidia conspicuous, clavate to bladder-like, filled with oily drops.
