Banhegyia

Banhegyia L. Zeller & Tóth, Sydowia 14: 326 (1960).

Index Fungorum number: IF 509; Facesoffungi number: FoF 00601, 1 morphological species (Species Fungorum, 2022), molecular data unavailable

Saprobic on Juniperus communis in terrestrial and marine habitats. Sexual morph: Ascomata apothecial, superficial, solitary, scattered, closed when young, opening when mature, exposing a roughened layer at the center, subglobose to disc-like, leathery, black. Exciple comprising an outer layer of dark brown to black, pseudoparenchymatous cells and an inner wall of relatively thin-walled cells of textura angularis. Hamathecium dense, hyaline, septate, unbranched pseudoparaphyses fusing at the apex to form the pale thin epithecium. Asci 8-spored, bitunicate, subglobose to obovoid, pedicel small, apically broadly rounded with a wide hyaline region, with an ocular chamber. Ascospores irregularly arranged, obovoid to ellipsoidal, upper cell usually larger than the lower cell, rounded at the ends, hyaline, becoming brown when old, 1-septate, constricted at the septa, with hyaline of bristle-like, appendages at the apex. Asexual morph: Unknown (adapted from Yacharoen et al. 2015).

 

Type species: Banhegyia setispora L. Zeller & Tóth

 

Notes: Banhegyia was introduced by Zeller and Tóth (1960) with B. setispora Zeller & Tóth as the type species. Banhegyia has unique ascospores with polar bristles. Müller and von Arx (1962) transferred B. setispora from Lecanorales to Patellariaceae and this was followed by many authors (Kohlmeyer, 1967; von Arx & Müller, 1975; Greuter et al., 1993; Hawksworth, 1997; Jones et al., 2009). However, molecular data is required to confirm the placement of Banhegyia in Patellariaceae.
