Bitter apple (Citrullus colocynthis), camelthorn (Alhagi sp.), cordia (Cordia myxa), dill (Anethum graveolens), eucalyptus (Eucalyptus sp.), licorice (Glycyrrhiza glabra), plantain (Plantago sp.), and rosemary (Rosmarinus officinalis) are medicinal plants distributed in different parts of Khuzestan province. These plants could be host to many pathogenic and non-pathogenic fungi. In this study, 30 samples from medicinal plants showing leaf spot, stem canker and stem necrosis were collected during 2019-2020, and in which 23 isolates of six species in the family Didymellaceae were identified. Molphological characteristics were studied on potato – dextrose - agar (PDA). For molecular study, partial regions of tub2 gene were amplified using appropriate primers and sequenced. Based on molecular phylogeny in combination with morphology, the isolates were identified as follow: Allophoma labilis, Didymella glomerata, Epicoccum italicum, Neodidymelliopsis farokhinejad, Nothophoma raii and Xenodidymella glycyrrhizicola. In our knowledge, this is the first report of above species on surveyed hosts and first record of both E. italicum and N. raii for mycobiota of Iran.

Abstract
In order to study the Bipolaris and Curvularia species associated with corn, sorghum and sugarcane, sampeling were performed from different regions of Iran (including Alborz, Ardabil, Fars, Gilan, Golestan, Khuzestan, Mazandaran and Zanjan provinces) during the summer of 2011 and 2012.

In order to study the Bipolaris and Curvularia species associated with corn, sorghum and sugarcane, sampeling were performed from different regions of Iran (including Alborz, Ardabil, Fars, Gilan, Golestan, Khuzestan, Mazandaran and Zanjan provinces) during the summer of 2011 and 2012. Fungal species were identified based on morphological features and molecular data of ITS regions of ribosomal DNA. Eleven species including Viz. Bipolaris cynodontis (48 isolates), B. sorghicola (16 isolates), B. maydis (17 isolates), B. sorokiniana (seven isolates), B. bicolor (four isolates) and B. oryzae (two isolates), Curvularia spicifera (19 isolates), C. papendorfii (ten isolates), C. ellisii (two isolates), and C. hawaiiensis (one isolate) were identified. Pathogenicity test of the species were performed on four to six leaf stage of corn, sorghum and sugarcane seedlings. Finally, pathogenicity of B. maydis, B. sorokiniana and B. oryzae on corn and B. sorghicola on sorghum seedlings were confirmed. This is the first report of occurrence and pathogenicity of B. sorokiniana and B. oryzae on corn leaves in Iran.

In a survey conducted to identify terrestrial nematodes of Roodghat area, Sufiyan-East Azerbaijan province, Iran, 80 soil samples were collected during 2016 and 2017. The soil samples were processed and the nematodes were extracted, killed, fixed, and transferred to anhydrous glycerin as usual. Permanent microscopic slides were prepared from the nematodes. Their morphological characteristics and morphometric properties were studied under an optical microscope consisting of a drawing tube. In this study, 35 species belonging to 25 genera (plant parasitic and non-plant parasitic) were identified that among them Axodorylaimellus deviatus (Baqri & Jairajpuri, 1969) Jairajpuri & Ahmad, 1980, Kochinema tenue Argo & Van Den Berg 1971, Laevides laevis (Thorne, 1939) Thorne, 1974, Metaporcelaimus labiatus (de Man, 1880) Andrássy, 2001andMetaxonchium bihariense (Popovici, 1990) Andrássy, 1996 were new records for the nematode fauna of Iran and are described here.
