Lichenotubeufia Etayo, Opera Lilloana 50: 255 (2017).
Index Fungorum number: IF 818341; Facesoffungi number: FoF 12023, 5 morphological species (Species Fungorum 2022), no molecular data available.
Lichenicolous. Sexual morph: Ascomata perithecial, superficial, solitary, scattered or in groups, subglobose to pyriform, beige to cream colored, hairy around the whole surface, not cupulate, not papillate, with a slightly darker spot around the ostiole. Peridium composed of several layers, hyaline to creamy colored, K+ slightly yellowish green, with isodiametric, thin-walled cells. Hairs hyaline, simple to septate, not branched, with acute apex, straight, thick-walled (with very thin lumen along the entire length) or solid in the apical part (with lumen only at the base). Hamathecium I–, KI–, composed of persistent, branched and anastomosed paraphysoids. Asci bitunicate, long cylindrical, with a short foot, with thickened apex, 8–spored, K/I–, endoascus K/I+ orange. Ascospores needle-shaped, acicular, with acute ends, multiseptate, hyaline. Asexual morph: Unknown (adapted from Lichenotubeufia cryptica in Flakus et al. 2019).
Type species: Lichenotubeufia eriodermatis (Etayo) Etayo
Notes: Lichenotubeufia is characterised by perithecial, superficial, solitary, scattered ascomata, long cylindrical asci with a short foot and needle-shaped, multiseptated, acicular ascospores with acute ends. Lichenotubeufia morphologically resembles Tubeufia but differs in ecology as it occurs on lichens while Tubeufia has a saprobic lifestyle. Zhurbenko (2022) introduced two new species of Lichenotubeufia and provided a key to species. Lichenotubeufia is a distinct genus in Tubeufiaceae but lacks molecular data. Fresh collections with DNA sequence data are needed to confirm the systematic position of Lichenotubeufia.
