Acanthocorticium Baltazar, Gorjón & Rajchenb., in Baltazar et al., Botany 93(8): 456 (2015)

Etymology: The name is referred to the presence of abundant acanthophyses, which are very conspicuous in Melzers reagent due to their dextrinoid reaction, besides the corticioid habit.

Diagnosis: Acanthocorticium is distinguished from other corticioid genera by the combination of dextrinoid acanthophyses, halocystidia that are finely echinulate at the apex, simple-septate generative hyphae, and globose, smooth, thin-walled and IKIbasidiospores.

Basidiome corticioid, resupinate, adnate, cartilaginous hard when dry. Hymenophore smooth to tuberculate, even to rimose. Hyphal system monomitic, generative hyphae simpleseptate. Halocystidia abundant in the subiculum and hymenium, hyaline, finely echinulate at the apex, IKIto slightly dextrinoid, with a resinous cap. Acanthophyses present in the subiculum and dominating in the hymenium, cylindrical to clavate, hyaline, with short protuberances in the apical portion, dextrinoid. Basidiospores globose, hyaline, smooth and thin-walled, IKI–.
