Patellaria
Patellaria Fr., Syst. mycol. (Lundae) 2(1): 158 (1822).
Index Fungorum number: IF 3765; Facesoffungi number: FoF 00343, 48 morphological species (Species Fungorum 2022), 4 species with molecular data.
Saprobic on dead wood, stems or rotten paper in terrestrial habitats. Sexual morph: Ascomata scattered, closed at first and opening at maturity, longitudinally wide, apothecioid, superficial, circular or elongate, with a carbonaceous rim, exposed flat, dark-brown. Exciple multi-layered and composed of isodiametric, thick-walled, dark brown cells at the outer layer, and lighter colored cells at inner layers. Hamathecium composed of pseudoparaphyses, septate, slender, hyaline, apically branched filaments when mature, forming a greenish brown epithecium above the asci. Asci 4–8-spored, bitunicate, fissitunicate, clavate to cylindrical, sometimes slightly fusiform, short pedicellate, apically rounded with an ocular chamber. Ascospores 2-seriateor overlapping 3-seriate, clavate, hyaline, slightly curved, and distoseptate. Asexual morph: Unknown (adapted from Hyde et al. 2013).
Type species: Patellaria atrata (Hedw.) Fr
Notes: Patellaria is characterised by scattered apothecioid, superficial, circular or elongate ascomata, multi-layered exciple, clavate to cylindrical asci and 3-seriate, clavate, hyaline ascospores. Members of Patellaria have varied number of asci and spore size and number of spores within the asci. Yacharoen et al. (2015) examined a specimen of Patellaria atrata (IMI 32777) and provided an updated illustration of the genus. Suetrong and Jones (2006), Suetrong et al. (2009), Boehm et al. (2009) and Schoch et al. (2009) carried out molecular investigations comprising taxa in Patellaria. Patellaria is a distinct and type genus of Patellariaceae. Molecular markers available for Patellaria are ITS, LSU, SSU, TEF-1 and RPB2.
