Abstract

During 2015–16, the presence of micromycetes species in aquatic ecosystems was studied in Iran. Samples were collected from rivers, lakes and wetlands. For isolation, agar disks were transferred to plates containing water samples.The plates were incubated at 25–27oC for 21 days in 12 h light/12 h dark condition. Then from the mycelium grown on the agar disks, pure cultures were obtained. Finally, an isolate was identified asAquanectria penicillioides (Ingold) L.Lombard & Crous, based on morphological and molecular data (sequences of ITS rDNA). Based on available literatures, this species is reported as new taxon for mycobiota of Iran and is described below: Colony on PDA reached 50 mm in diam., after 14 days at 25oC in continuous dark condition. The hyphae are colorless (Fig.1a). Chlamydospores were formed in moniliform chain, brown in color and 15–28 (20) × 10–16 (14) mm in diameter (Fig.1b). The colony on PDA forms few or no conidiophores but, if a small mycelial disc is cut off and submerged in water, numerous submerged conidiophores will be produced within two days. The submerged conidiophores are hyaline and penicillium-like (Fig.1c, d); apical phialides are 15–21 (18) mm long, 2–2.5 mm wide.Conidia (phialospores) are 31–48 (39.5) mm long, 2–2.5 (2.3) mm wide and each conidium is curved or sigmoid. The hyaline conidia may be aseptate or divided by a single septum into two, more or less equal cells (Fig.1e, f).Specimen examined: Iran: Lorestan province, Kaka Reza river, 18.10.2015, Razieh Poursaeid (IRAN 2794C).Morphological features of this isolate were similar to that of A. penicillioides described by Ingold (1944).Lombardet al. (2015) showed that, the aquatic genus Aquanectriawas established to accommodate two fungal species previously treated as members of the genera Flagellosporaand Heliscus (Ingold 1942, Ranzoni 1956). In the present study, the sequence of Aquanectria (accession number: MF085359) showed 99% homology with valid sequences of previously identified and deposited data in the GenBank. Phylogenetic trees constructed based on ITS regions sequences showed that, the Iranian specimen is placed in the same clade with A. penicillioidesreported from other authors (Fig.2).
