Abstract

During the investigation of fungi associated with black (sooty) head mold of wheat and barley in different regions of Golestan, Alborz and Qazvin provinces (Iran) in growing seasons of 2014–15, several isolates with typical characteristics of the genusHarzia Costantin were collected. Based on the morphological characteristics, all isolates were identified as H. acremonioides (Harz) Costantin. To the best of our knowledge, this is the first report of the species to the mycobiota of Iran and is described below: Colonies on malt extract agar (MEA) fast growing, reaching 7 cm diam. after seven days at 23–25° C under continuous darkness, at first colorless, later pale brown to cinnamon brown, effuse, cottony. Sporulation abundant, mostly from surface and to a lesser extent from aerial mycelia (Figs 1A, B). Hyphae hyaline, septate and branched, 5–7 mm in wide. Conidiophores hyaline, sympodially branched, straight or slightly curved, 1–2 septate, tapered to a fine tip point, up to 70 mm long, 5–7mm wide near the base and tapering to 1–2 mm tip (Figs 1C, D). Blastoconidia are produced at the tip of the conidiophores and their branches, solitary, dry, one celled, globose to obovoid, almost smooth walled, colorless at first, later becoming light brown to cinnamon brown, 19–28 × 16–24 mm (Figs 1E, F). A phialidic anamorph attributed to this species in some literature, was not observed in this study.To confirm the morphological identification, isolate HA-1 was selected for DNA analysis. The nuclear ITS-rDNA was amplified and sequenced using ITS4/ITS5 primer pairs (Whiteet al.1990). The resulting sequences were deposited in Gen Bank under accession number KX064398. Blast search of obtained sequencesin GenBank showed a high nucleotide similarity (99%) with that ofH. acremonioides strain NRRL 54327 (HQ698593).The genusHarzia contains four accepted species, namely, H. acremonioides, H. cameroonensis, H. velata, and H. verrucosa which are often distinguished from each other by conidium characteristics (Domschet al.2007, Crouset al.2013). Harzia acremonioides is the most common species of the genus and has been reported from all climatic regions of the world. It has frequently been isolated from seeds of different plant species and from a lot of other different substrates (Blaszkowski & Piech 2002, Domschet al.2007, Seifert et al.2011).However, in Iran, H. verrucosa has been reported from barley grains in Golestan province (Ahmadi & Sadravi 2008).Harzia acremonioides can be easily distinguished from H. verrucosa by its verrucose, globose to subglobose and smaller (16–23 mm diam.) conidia.Specimens examined: Iran: Golestan province, Gonbade-Kavous, barley head, May 2015, A. Poursafar, isolate HA-1 (IRAN 2839C); Kordkuy, wheat head, May 2015, A. Poursafar, isolate KQ8-10.
