Tubeufiales » Tubeufiaceae


Bifrontia Norman, Bot. Notiser: 18 (1872).

 Index Fungorum number: IF 569; Facesoffungi number: FoF 00175, 2 morphological species (Species Fungorum 2020), molecular data unavailable.

Saprobic on dead leaves Nectandra sp. Sexual morph: Ascomata black, solitary or somewhat gregarious, superficial, linear, flat, dehiscing with raised central rounded ostiole, multilocular, glabrous. Apothecial wall composed of black cells of textura intricata in the upper part, become hyaline cells of textura angularis in the basal part. Asci hyaline, bitunicate, 8-spored, numerous, irregularly or lenearly arranged, fusiform, broadly ovate, wedge-shaped, subglobose or irregular, broadly rounded above, narrow below, short-stalked or stalked, smooth-walled. Ascospores hyaline, oblong, 2–4 seriate or multiseriate, thick-walled, slightly curved, broadly rounded above, narrow below,uniseptate, slightly constricted at the septum, smooth. Asexual morph: Unknown (adapted from Boonmee et al. 2014b).


Type species: Bifrontia compactior Norman


Notes: Bifrontia is characterised by black, solitary ascomata, hyaline, bitunicate, 8-spored asci and hyaline, oblong, 2–4 seriate or multiseriate, uniseptate ascospores. Boonmee et al. (2014b) studied the holotype of B. compactior and designated the species as the lectotype of the genus. Boonmee et al. (2014b) accepted Bifrontia as a genus of Tubeufiaceae. Molecular data is lacking. Fresh specimens with DNA sequence data are needed to confirm the systematic position of Bifrontia.
