MycoBank number: MB 553776; Index Fungorum number: IF 553776; Facesoffungi number: FoF03604; 4 species.
Saprobic on fabaceous hosts. Sexual morph: Pseudostromata conspicuously pulvinate to inconspicuous, embedded in host tissue or erumpent to rarely superﬁcial, visible as raised, dark spots on the host surface, more or less elevated patches on the wood or erumpent through the bark, yellowish, brown to black; sometimes covered by yellow to yellow-green, bright turquoise, scurf. Ascomata perithecial, immersed in pseudostroma, multi-loculate, aggregated, globose, subglobose to conical or irregular, subhyaline to pale brown, ostiolate. Ostioles papillate. Peridium composed of subhyaline to medium brown cells of textura angularis to textura prismatica, KOH-. Paraphyses septate, unbranched or occasionally branched, hyaline. Asci 8-spored, unitunicate, arising from the base or margins of the ascomata, clavate to cylindrical, straight, curved to sinuous, thin-walled, J-, without a distinct apical ring. Ascospores bi-seriate to uniseriate, hyaline, ellipsoid or allantoid, equilateral or inequilateral, with rounded apices, aseptate or 1-septate, not constricted at the septa, thin-walled, smooth, without appendages or gelatinous sheath. Asexual morph: Undetermined.
Type genus – Delonicicola R.H. Perera, Maharachch. & K.D. Hyde
Notes – Perera et al. (2017) introduced Delonicicolaceae (Delonicicolales) to accommodate Delonicicola and Liberomyces. Liberomyces was synonymised under Leptosillia and added to Leptosilliaceae (Voglmayr et al. 2019a). A new genus Furfurella was added to Delonicicolaceae based on morphological and molecular evidence by Voglmayr et al. (2019a). Vitale et al. (2018) and Voglmayr et al. (2019a) accepted Delonicicolaceae within Xylariales. However, based on our phylogenetic analysis (Fig. 4) we maintain Delonicicolaceae in Delonicicolales following the classification of Perera et al. (2017).
