Aquascypha

Aquascypha D.A. Reid 1965, in Gorjón, Studies in Fungi 5(1), 163 (2020).

Diagnosis: Basidiome coriaceous, centrally stipitate, infundibuliform, often coalescent, pileus minutely tomentose or velutinate, concentrically zoned, varying in colour from dark brown to dark purple-brown, normally bearing conspicuous flattened dendroid or antler-like processes, hymenial surface smooth, distinctly pruinose, ochraceous-buff near the margin but becoming almost white towards the stipe in well preserved specimens. Stipe relatively short, minutely velutinate, dark brown to dark purple brown, arising from a well-developed basal disc of mycelium. Flesh of the pileus creamy-white, becoming dark brown in the region of the hymenium. Hyphal system trimitic, consisting of thin-walled, hyaline, branched generative hyphae, which bear inconspicuous clamp-connexions at the septa; thick-walled, unbranched skeletal hyphae which are distinctly brownish in colour; and thick-walled, pale brownish or hyaline, branched binding hyphae, lacking clamp connexions and in which the branches are of limited growth. Cystidia and gloeocystidia absent. Basidia not seen. Basidiospores hyaline, smooth, globose or subglobose, cylindrical (according to Ryvarden 2010).
