Tryblidaria (Sacc.) Rehm, Hedwigia 42: 173 (1903).
≡ Blitrydium subgen. Tryblidaria Sacc., Syll. Fung. (Abellini) 8: 805 (1889).
Saprobic on bark in terrestrial habitats. Sexual morph: Ascomata apothecial, superficial, cupshaped, scattered, occasionally in groups of 3–5, globose, carbonaceous, gray or black, with raised rim. Peridium (exciple) relatively wide, carbonaceous, dark brown, comprising pseudoparenchymatous cells, which are hard to distinguish. Hamathecium composed of filamentous, unbranched, trabeculate, filiform, hyaline, pseudoparaphyses, embedded in a gelatinous matrix, forming a light brown epithecium above the asci. Asci 8-spored, bitunicate, broadly clavate, wide in the middle, narrow at the base with a long pedicel, narrow at the apex, with an indistinct ocular chamber. Ascospores 1–2-seriate overlapping, ellipsoidal to oblong, multiseptate or muriform, hyaline to light brown. Asexual morph: Unknown (Adapted from Yacharoen et al., 2015)
Type species: Tryblidaria fenestrata (Cooke & Peck) M.E. Barr
Notes: Tryblidaria was introduced by Saccardo (1889) as a subgenus. Tryblidaria was raised to generic rank by Rehm (1904). T. fenestrata was designated as the type species of Tryblidaria by Clements and Shear (1931) and this was followed by subsequent studies (Kutorga & Hawksworth, 1997). However, according to Index Fungorum (2022), the type species of Tryblidaria is T. breutelii. Tryblidaria needs revision. Tryblidaria is currently placed as a distinct genus in Patellariaceae.
