“…was found to form a distinct acremonium-like asexual morph in culture, for which the monotypic genus Calosphaeriophora (Calosphaeriophora pulchella Réblová et al as type) was proposed ). It causes almond die back in Iran and has an impact on the almond industry (Arzanlou and Dokhanchi 2013). Calosphaeriophora becomes a synonym of Calosphaeria.…”

Sordariomycetes is one of the largest classes of Ascomycota and is characterised by perithecial ascomata and inoperculate unitunicate asci. The class includes many important plant pathogens, as well as endophytes, saprobes, epiphytes, and fungicolous, lichenized or lichenicolous taxa. The class includes freshwater, marine and terrestrial taxa and has a worldwide distribution. This paper provides an updated outline of the Sordariomycetes and a backbone tree incorporating asexual and sexual genera in the class. Based on phylogeny and morphology we introduced three subclasses; D i a p o r t h o m y c e t i d a e , L u l w o r t h i o m y c e t i d a e a n dTogniniales. The outline is based on literature to the end of 2014 and the backbone tree published in this paper. Notes for 397 taxa with information, such as new family and genera novelties, novel molecular data published since the Outline of Ascomycota 2009, and new links between sexual and asexual genera and thus synonymies, are provided. The Sordariomycetes now comprises six subclasses, 28 orders, 90 families and 1344 genera. In addition a list of 829 genera with uncertain placement in Sordariomycetes is also provided.

Production from crops of pome, stone fruit, nut, berry fruit, citrus, grapevine, and olive is increasingly threatened by fungal trunk diseases (FTD). These diseases and the consequent production losses are major problems. Many fungi (including Botryosphaeriaceae, Calosphaeriaceae, Diaporthaceae, Diatrypaceae, Nectriaceae, Phaeomoniellaceae, Pleosporaceae, Togniniaceae, Valsaceae) infect host wood, mainly through wounds and subsequent colonization of woody tissues, causing symptoms such as cankers, gummosis, wood rotting, blight and dieback. Propagative plant material, seedlings and fruit play a significant role in pathogen spread. Several abiotic factors (e.g. shifts in cultural practices and climate change) are involved in the disease development. This paper reviews recent literature on FTD of fruit crops, particularly focusing on the European status of pathogen occurrence. Case studies are described related to diseases of apple, citrus, grapevine, berry, nut and stone fruit, and olive trees. Aspects related to epidemiology and the increase in disease incidence along with the future perspectives on the FTD research are also discussed.

During 2014-2016, symptoms and signs of a powdery mildew disease were observed on the leaves and twigs of sour cherry (Prunus cerasus) in orchards from Firouragh in the Khoy region (West Azarbaijan province) of Iran. Young leaves and twigs were covered with a powdery growth consisting of mycelium and the asexual reproductive structures of a powdery mildew species. Affected leaves were curled upward and smaller than uninfected leaves, while affected twigs were stunted and often defoliated. The fungus was identified as belonging in the genus Podosphaera, based on morphological characteristics of its asexual state. Chasmothecia were not observed. The PCR amplification and sequencing of its ITS-rDNA revealed that the causal agent was Podosphaera clandestina. This is the first record on the occurrence of P. clandestina on sour cherry in Iran.Keywords Chasmothecia . Fibrosin bodies . ITS-rDNA . Prunus cerasusSour cherry (Prunus cerasus) belongs in the subgenus Cerasus in the family Rosaceae. The presumed center of origin for this species is Eastern Europe and southwest Asia, where it originated as a natural hybrid between Prunus avium and Prunus fruticosa (Horvath et al. 2008). Sour cherry is a popular fruit tree in many countries including Iran. According to the statistics of Food and Agriculture Organization (FAO) of the United Nations, in 2013 Iran ranked the fifth in sour cherry production in world with an annual production of 106,972 t (FAOSTAT 2013). Although sour cherry is undemanding and very robust, a number of fungal plant pathogens including Monilinia laxa and Stigmina carpophila cause economic crop loss on this host in Iran (Ahmadpour et al. 2009;Leghvani et al. 2016). During 2014-2016, symptoms and signs of a powdery mildew disease were observed on sour cherry trees in orchards of Firouragh in the Khoy region (West Azarbaijan province), Iran. Infected leaves and twigs were collected in paper bags and transported to the mycology laboratory at the Plant Pathology Department, University of Tabriz, Iran. Five specimens were inspected under a stereomicroscope and fungal structures were mounted in distilled water on a glass slide, covered with a coverslip then examined. Microscopic observations were made using an Olympus-BX41 light microscope. Thirty measurements were taken of the relevant parameters of the conidiophores and conidia and 95% confidence intervals were derived for the measurements with the extremes given in parentheses. An Olympus digital camera system (DP 25) and software to analyze photographs was used to capture high-resolution photographs of microscopic fungal structures. A herbarium specimen was deposited in the Fungal Herbarium of the Iranian Research Institute of Plant Protection (IRAN 16861F).The white powdery coating consisted of mycelium, conidiophores and conidia. The infected terminal leaves were smaller than uninfected terminal leaves with the leaf margins curled upward; infected leaves occasionally became necrotic and defoliated (Fig. 1a-b). The sunken irregular lesions (4-)...
