Xylariomycetidae, Amphisphaeriales, Cylindriaceae, Cylindrium

Index Fungorum number: IF7865; Facesoffungi number: FoF 09180; 10 morphological species (Species Fungorum 2020); 3 species with sequence data.


Associated with plant substrates, especially leaves. Sexual morph: Undetermined. Asexual morph: Mycelium composed of septate, branched, hyaline, smooth-walled hyphae. Conidiophores sporodochial or solitary, erect, hyphae and basal part of conidiophores subcylindrical, septate, branched, becoming pale brown, smooth-walled. Conidiogenous cells terminal and intercalary, subcylindrical, hyaline, smooth-walled, with several sympodial flat-tipped loci, unthickened, not darkened. Ramoconidia subcylindrical, guttulate, hyaline, smooth-walled. Conidia aseptate, arranged in long, branched chains, scars not thickened, slightly refractive, hyaline, smooth-walled (adapted from Crous et al. 2018).


Type species: Cylindrium elongatum Bonord., Handb. Allgem. mykol. (Stuttgart): 34 (1851)


Notes: This asexual morph genus is characterized by sporodochial conidiomata, subcylindrical conidiogenous cells and aseptate hyaline conidia arranged in long chains (Bonorden 1851, Crous et al. 2018). The taxonomic placement of Cylindrium was doubtful for years. Cylindrium elongatum was accepted in Hypocreales incertae sedis by Lombard et al. (2015). Crous et al. (2018) revealed that Cylindrium is a member of Hypocreales and described Cylindriaceae based on ITS sequence data. Cylindrium elongatum however grouped within Amphisphaeriales in the phylogenetic analysis conducted by Hyde et al. (2020).
