Classification: Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Endophytic, pathogenic or lichenized. Sexual morph: Ascomata perithecial, superficial to partly immersed, scattered or collapsed, black. Ostioles central, papillate, base of canal sulcate, sometimes with hyaline periphyses. Peridium melanized, KOH- , comprises cells of textura angularis or prismatica. Paraphyses septate, occasionally branched, embedded in a gelatinous matrix. Asci 8-spored, clavate to cylindrical, curved or sinuous, with J+, apical ring. Ascospores bi or tri-seriate or fasciculate, hyaline, falcate, lunate, sinuous, sigmoid to hook-shaped, aseptate or septate, not constricted, thin and smooth-walled, with rounded to subacute apices, without appendages or gelatinous sheath. Asexual morph: Coelomycetous. Conidiomata superficial to partly immersed, scattered, aggregated or confluent, globose to pyriform, uni or irregularly pluriloculate, black. Conidiomatal wall more or less melanized, textura globulosa or angularis. Conidiophores hyaline, short with arising from the inner layer of the peridium. Conidiogenous cells cylindrical to lageniform. Conidiogenesis enteroblastic phialidic or holoblastic with sympodial proliferation to both types. Conidia falcate or filiform, aseptate, hyaline, allantoid, thin-walled (adapted from Voglmayr et al. 2019a).
Notes: Leptosilliaceae was introduced by Voglmayr et al. (2019a) which belongs to Xylariales and is morphologically similar to Delonicicolaceae, but differs in ascomata structure. Only one genus, Leptosillia is recognized in the family based on molecular and morphology data (Voglmayr et al. 2019a). Voglmayr et al. (2019a) clearly showed Leptosillia should be placed in the Xylariales with strong evidence from ITS and LSU analyses. However, in this study we accept this family under Delonicicolales, based on high statistical support.
Type genus: Leptosillia Höhn.
