MycoBank number: MB 551190; Index Fungorum number: IF 551190; Facesoffungi number: FoF 00681; 10 species.
Saprobic on leaves, twigs and branches of dicotyledons especially on Eucalyptus (Myrtaceae). Sexual morph: Pseudostroma solitary, black, scattered, immersed. Ascomata forming under pseudostroma, solitary, brown to black, scattered, globose, coriaceous, ostiolate, papillate. Papilla short, narrow, surrounding thickened. Peridium comprising outer, brown thick-walled cells of textura angularis and inner, hyaline, thin-walled cells of textura angularis. Asci 8-spored, unitunicate, cylindrical, short pedicellate, rounded at apex, with J+, discoid, subapical ring. Ascospores overlapping uniseriate, hyaline, fusiform, rounded at ends, 1-septate, slightly constricted at septa. Asexual morph: Coelomycetous. Conidiomata appearing as slimy, erect tufts of hyaline conidial masses, eustromatic, unilocular or multilocular, sporodochial, synnematous, indeterminate, turning brown with age. Conidiophores brown, smooth, branched. Conidiogenous cells annellidic, smooth, hyaline becoming light brown with maturity, subcylindrical, ampulliform with elongated necks, often having percurrent proliferations. Conidia cylindrical to subcylindrical, fusoid, hyaline, straight, smooth, rounded apex, rounded or subobtuse apex, truncate base, aseptate to 1-septate, guttulate (adapted from Senanayake et al. 2015).
Type genus – Phlogicylindrium Crous, Summerb. & Summerell
Notes – Senanayake et al. (2015) introduced Phlogicylindriaceae to accommodate the genera Phlogicylindrium and Ciferriascosea. The asexual genus produces slimy erect flame-like tufts of hyaline conidial masses, and cylindrical, unicellular to 1-septate, hyaline conidia (Summerell et al. 2006). The sexual morph of Phlogicylindrium has not been reported. Ciferriascosea is a sexual genus with no reported asexual morph, and was included in Phlogicylindriaceae due to its phylogenetic affinity to Phlogicylindrium (Senanayake et al. 2015). The sexual genus Idriellomyces was introduced in Phlogicylindriaceae by Crous et al. (2018c) based on its distinct morphology and molecular data.
