Phlyctaeniella Petr., Annls mycol. 20(5/6): 323 (1922).
Associated with leaf spot. Sexual morph: Unknown. Asexual morph: Mycelium immersed, branched, septate, hyaline. Conidiomata eustromatic, separate, immersed, pale brown, globose, unilocular, scarcely erumpent; side wall and base of several cell layers of hyaline, thin-walled textura angularis, above of larger pale brown tissue. Ostiole indistinct, and dehiscence by rupture of the upper wall. Conidiophores hyaline, smooth, septate, irregularly branched, especially at the base, formed from the inner cells of the stroma wall. Conidiogenous cells phialidic, integrated or discrete, determinate, hyaline, markedly tapered at the apices, smooth, with apical or lateral apertures, collarette minute, with periclinal thickening; only rarely becoming percurrent. Conidia hyaline, smooth, thin-walled, irregularly guttulate, filiform, straight, curved or irregular, multiseptate (adapted from Sutton 1980; Quaedvlieg et al. 2013 and Videira et al. 2017).
Type species: Phlyctaeniella polonica Petr.
Notes: Phlyctaeniella is characterised by eustromatic, separate, immersed, pale brown, globose conidiomata, with ab indistinct ostiole, phialidic, integrated or discrete conidiogenous cells and hyaline, smooth, thin-walled conidia. The placement of Phlyctaeniella in Mycosphaerellaceae is doubtful. Fresh collections with DNA sequence data are needed to confirm the taxonomic placement of Phlyctaeniella.
