Ascocylindrica Abdel-Wahab, Bahkali & E.B.G. Jones, in Ariyawansa et al., Fungal Diversity: 10.1007/s13225-015-0346-5, [20] (2015).
Index Fungorum number: IF 551414; Facesoffungi number: FoF 00954, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on drift and submerged mangrove wood. Sexual morph: Ascomata globose to subglobose, immersed, erumpent to superficial, solitary, ostiolate, papillate, periphysate, coriaceous, dark brown to black. Peridium comprising two strata, outer stratum a thin, black, amorphous layer, inner stratum comprising hyaline thick-walled cells arranged in a textura angularis. Hamathecium comprising numerous, 0.5–1 μm wide, septate, branched, trabeculate pseudoparaphyses, within a gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, cylindrical, short pedicellate, apically rounded, with a wide, shallow ocular chamber. Ascospores uniseriate to overlapping uniseriate, dark brown to black, 1- septate. Asexual morph: Unknown (adapted from Ariyawansa et al. 2015).
Type species: Ascocylindrica marina Abdel-Wahab, Bahkali & E.B.G. Jones
Notes: Ascocylindrica was introduced by Abdel-Wahab in Ariyawansa et al. (2020) with A. marina as type species. Ascocylindrica is characterised by globose to subglobose ascomata, cylindrical, short pedicellate asci and uniseriate to overlapping uniseriate, dark brown to black, 1- septate ascospores. Ascocylindrica resembles Halokirschsteiniothelia in having small ascomata and bi-celled brown ascospores but differs in that the latter genus has subconical ascomata with a flattened base, clavate to oblong ellipsoidal asci and longer, smooth ascospores, with a submedian septum. Ascocylindrica also resembles Lineolata but can be differentiated in that the latter genus has a multi-layered refractive ascal ring (Kohlmeyer & Volkmann-Kohlmeyer 1990). Ascocylindrica is a distinct and well-defined genus in Ascocylindricaceae. Molecular markers available for Ascocylindrica are LSU and SSU.
