Patellariopsidaceae Karun., Camporesi and K.D. Hyde, Fam. Nov.
MycoBank number: MB 556719;Index Fungorum number: IF 556719, Facesoffungi number: FoF 06573
Sexual Morph: Ascomata apothecial, discoid, sessile or stipitate. Ectal excipulum composed of cells of textura globulosa to angularis cells. Medullary excipulum composed of interwoven refractive hyphae. Paraphyses filiform branched and pigmented at the apices. Asci 8-spored, cylindric-clavate, amyloid. Ascospores ellipsoid to fusoid, hyaline, 3–7-septate. Asexual morph: Saprobic on dead branch of Corylus avellana (Betulaceae). Sporodochium, sub-epidermal or sub-peridermal, solitary. Conidiophores cylindrical, straight or slightly curved, branched over the conidiophore, septate, hyaline, expanding toward the apices, smooth. Conidiogenous cells holoblastic, polyblastic, cylindrical, integrated, hyaline, and smooth. Conidia, sphaerical, proliferating with several, short, lateral, acropetal, branched chains. Primary branches in turn develop secondary branches, which eventually form a globose to cylindrical mass of small, thick-walled, dark brown, septate, eguttulate, smooth, cheiroid, conidium-complex.
Notes
Patellariopsidaceae forms a well-supported (ML 74/BYPP 0.98) clade sister to Chlorospleniaceae, Loramycetaceae, Mollisiaceae and Vibrisseaceae. In Index Fungorum, Patellariopsis is included in Dermateaceae, but Wijayawardene et al. (2017) placed Patellariopsis in Helotiales genera incertae sedis based on morphology. Furthermore, in Ekanayaka et al. (2019), this clade was denoted as separate taxa based on phylogenetic analyses. Hence, we introduce this clade as a new family based on morphology and phylogeny.
