Specimens belonging to the genus Carex sect. Ammoglochin from W Azarbaijan province (W Iran) were studied and Carex iraqensis and C. disticha are reported for the first time from Iran. These species are characterised and illustrated and a determination key for species of sect. Ammoglochin is presented. Taxonomic relationships and distributions are discussed in the Persian text which is also summerised here: Carex iraqensis Kukkonen & Hooper (Figs 1 & 3) Specimens examined: Iran, W Azarbaijan province, Piranshahr, Silveh, Zivkeh, Chighidarreh mountain, 2433 m, 04.07.2012, Amini Rad & Torabi (IRAN 57470); Piranshahr, Mashkan, 2260 m, 03.07., Amini Rad & Torabi (IRAN 57468). Carex disticha Huds. (Figs 2 & 3) Specimen examined: Iran, W Azarbaijan province, Khoy, 3 km after Habash to Ghotour, 1940 m, 01.07.2012, Amini\ Rad & Torabi (IRAN 57469).

The vegetation of Eshtehard salt marshes in Karaj was studied, using the Braun-Blanquet method. Sixty five relevés recorded in different salt habitats were analyzed by Analyse Factorielle des Correspondances (AFC) and Classification Ascendant Hierarchique (CAH) methods, using the Anaphyto software. In general, 11 plant associations determined in the area: Aeluropodetum littoralis, Artemisietum sieberi, Atriplicetum verruciferae, Halimocnemietum rarifoliae, Halocnemetum strobilacei, Lepidietum pumili, Lycietum ruthenici, Phragmitetum stenophyllae, Salsoletum crassae, Salicornietum europaeae and Tamaricetum kotschyi. In addition, some of physical and chemical soil characteristics of plant association’s habitats were also measured. Principal Component Analysis (PCA) was used to analyze the soil data. The results showed that, the most important soil characteristics affected on plant association’s distribution were EC, pH, Na, Ca, Mg, Cl, SO4, HCO3 and texture of soil.

During the study on rust mycobiota of Central Alborz, several rust infected specimens belonging to Salicaceae family including Populus and Salix species were investigated. Populus nigra, P. euphratica, Saix alba and S. excelsa were infected by various Melampsora species. Uredinial (II) and telial (III) stages of rust were present on infected plants. According to morphological characters, five following species were identified: M. pruinosa on P. euphratica, M. amygdalinae on S. excelsa and M. dimorphopora, M. repentis and M. abieti-caprearum on S. alba. All identified rust species were documented by descriptions and LM and SEM photomicrographs. According to available literature all above mentioned rust species are new to the Iranian rust mycobiota.

One hundred isolates of Fusarium solani species complex were isolated and identified from 58 agricultural soil samples collected from different geographical regions in Kermanshah, Hamadan and Kurdistan provinces of Iran. Based on morphological characteristics, Fusarium falciforme, F. petroliphilum, F. keratoplasticum and F. pseudensiforme, are reported for the first time from Iran.

In this paper, five species of the agaric fungi viz., Entoloma griseoluridum, E. niphoides, Limacella ochraceolutea, Mycena clavicularis and M. acicula belonging to family Amanitaceae, Entolomataceae and Mycenaceae, are reported for the first time for Iranian mycobiota. Limacella ochraceolutea is the first species of fungi belonging to genus Limacella in Iran. Because L. ochraceolutea is a rare species and considered as near threatened, endangered or extinct, collecting such endangered species in Iran is a valuable finding. Entoloma niphoides is the first species of an agaric fungus in Iran with special association with root of woody plant of Rosaceae. More information on the studied specimens is as follows: Entoloma griseoluridum (Kühner) M.M.

In order to identify some endophytic fungi in common yew trees, healthy plant samples were investigated. In this study, 10 fungal species including Absidia spinosa, Aureobasidium pullulans, Lecanicillium lecanii, Nemania serpens,Pseudodictyosporium elegans, Leucostoma persoonii, Epicoccum nigrum, Stachybotrys chartarum, Gibberella tricincta and Gibberella baccata were identified as endophytic fungi of native common yew trees in Iran. Two taxa including P. elegans and N. serpens are being reported as new for the Iranian mycobiota. Also, all identified species except G. baccata, are reported for the first time as endophytic fungi of common yew trees (Taxus baccata) in the world.

The genus Tortula includes about 114 species in the world and 18 species were found in Iran. In the present paper, T. vahliana (Schultz) Mont. is reported for the first time from Iran.

In order to identify the endophytic fungi of stone fruit trees in West Azarbaijan province (Iran), healthy tissues were collected from various regions. For isolation of endophytic fungi, plant tissues were primarily washed with tap water, then surface sterilized by rinsing in 75% ethanol for 1 minute, followed by 5 minutes in 3% sodium hypochlorite (active ingredient). Disinfested pieces were then washed with distilled water, damp dried and plated onto culture media PDA and PCA (Schulz et al. 1993). Fungi growing from the margins of plant tissues were transferred separately into new culture media and purified by hyphal tip or single spore methods. After isolation of endophytic fungi, some isolates were identified as Sordaria fimicola (Roberge ex Desm.) Ces. & De Not.

A sample collected from the citrus orchards of the Sari Township, Mazandaran province (N Iran), was determined as Araujia sericifera Brot. (Apocynaceae), according to Markgraf (1972). This species and the genus Araujia, is new to Iran and the region covered by Flora Iranica (Rechinger 1970, 1974).

Amongst the specimens collected in May 2010, a new entomopathogenic fungus was identified as Neozygites microlophii which is a new record for Iran flora.

Non-agaric macrofungi of Hamedan province (Iran), belonging to the genus Verpa Sw. (family Morchellaceae), were collected and identified based on morphological features (Dennis 1981 and Häffner 1991).
