Abstract

During the visits of common reed [Phragmites australis (Cav.) Trin. ex Steud] in different locations of West Azerbaijan province during 2015–16, symptoms of fungal infections was frequently observed. Among the isolated and studied fungi, Deightoniella arundinacea (Corda) S. Hughes was commonly observed. Based on available literatures, this species was found new to mycobiota of Iran and is described below: The fungus causes dark grey to black lesions with yellow to light brown halos on both leaf surfaces (Fig.1a).Conidiophores macronematous, mononematous, straight or flexuous, unbranched, light brown, smooth, 43–95 × 4–9.5mm, basal cell swollen, 10–13 mm wide, erupt on both leaf surface. Conidiogenous cells are terminal, cylindrical, with thick side walls and a thin apical wall, integrated, percurrent, monoblastic (Figs 1b–d). After detaching the first formed conidium, the thin apical wall of the conidiogenous cell apparently collapse, the growth of conidiophore is resumed from inner and mostly from the base and the new section of conidiophore pushes through the apex of old one (Fig.1e).This process is repeated many times (Figs 1f–g). Conidia solitary, obpyriform, acrogenous, light brown to golden brown, 1–2 septate, with a distinct hilum, 19–52 × 10–18 mm (Figs 1h–j).Specimens examined: isolate Pa-12, Iran, West Azerbaijan province, Nazloo, Jun.2015, Y. Ghosta; isolate Pa-25, Urmia Lake, Jul.2015, Y. Ghosta; isolate Pa-49, Naqhadeh, Jun.2016, M. Abrinbana; isolate Pa-124, Mahabad, Aug.2016, M. Abrinbana (All fromPhragmites australis leaves).Based on Index Fungorum (Aug.2016, www.indexfungorum.org), 20 species are listed underDeightoniella.Among them, three speciesviz. D. arundinacea, D. constantinescui and D. roumegueri have been reported from Phragmites australis, although D. arundinacea has widespread distribution (Barbosa et al.2007, Bahçecioglu & Kabaktepe 2009, Hughes 1952, Mel' nik & Shabunin 2011). These species are differentiated on the basis of conidium characteristics (size, shape and septation).
