Geesterania Westphalen, Tomšovský & Rajchenb. 2018, in Westphalen et al., Persoonia-Molecular Phylogeny and Evolution of Fungi, 41(1), 130-141 (2018).

Etymology: Named in honor of Rudolph Arnold Maas Geesteranus (The Hague 1911Oegstgeest 2003) for his extensive contribution to the mycology, including studies of the genus Steccherinum and of several phlebioid species.

Diagnosis: Geesterania is characterised by the basidiomes becoming reddish when bruised, the abundant, long, thin- to thick-walled, finely encrusted skeletocystidia, the metachromatic skeletal hyphae and cystidia, a bipolar mating system and astatocoenocytic nuclear behavior.

Basidiomes resupinate, adnate, becoming reddish when bruised and/or upon drying, soft to fleshy when fresh, becoming harder and somewhat waxy when dried. Hymenophore poroid; pores regular to irregular, round to angular. Hyphal system dimitic, generative hyphae clamped, skeletal hyphae metachromatic, hyphae IKI-. Skeletocystidia present in the trama and dissepiments, cylindrical to clavate, encrusted at the apex with thin crystals, usually very long and appearing as skeletal hyphae ends, metachromatic, IKI-. Basidiospores ellipsoid to subcylindrical, hyaline, smooth, IKI-.
