“…Extensive studies have been carried out on trunk diseases of grapevine worldwide, and wide array of fungal groups has been characterized in association with trunk disease symptoms (Mostert et al 2003(Mostert et al , 2005(Mostert et al , 2006Urbez-Torres et al 2014;Gramaje et al 2015). While some of these fungal species have proven to be pathogenic on grapevine, the pathogenic potential of many species still remains to be tested.…”

Trunk diseases are potential threats for almond productivity and longevity worldwide, including Iran. In a recent survey on fungal species associated with trunk diseases of almonds in north‐western Iran, Collophora isolates (tentatively identified as Collophora hispanica) were recovered with high frequency from wood samples with internal necrosis and brown to black vascular streaking of almond trees showing symptoms of decline. However, the pathogenic potential of Collophora isolates on almond trees in Iran remains unproven. In this study, the identity of the isolates was further confirmed as C. hispanica based on a combination of morphological data and sequence data of ITS‐rDNA region, and pathogenicity of C. hispanica isolates on almond was evaluated using excised shoot method and in greenhouse experiments. Collophora hispanica isolates induced lesions statistically different from the control, in both excised shoot method and greenhouse assays. Significant differences were observed among the isolates in the length of the lesion induced on wood. Collophora hispanica should be considered as the main trunk pathogens of almond trees in north‐western region of Iran. The distribution and host range of this new pathogen on almond remains to be studied.

“…In a recent comprehensive review by Gramaje et al (2) on the nomenclature of this genus, 11 Phaeoacremonium species have been confirmed as human opportunistic pathogens causing infections in both immunocompromised and immunocompetent hosts. The most frequent species identified in human infections are P. parasiticum, P. inflatipes, and P. rubrigenum (3,4).…”

hIn vitro susceptibilities of a worldwide collection of molecularly identified Phaeoacremonium strains (n ‫؍‬ 43) belonging to seven species and originating from human and environmental sources were determined for eight antifungal drugs. Voriconazole had the lowest geometric mean MIC (0.35 g/ml), followed by posaconazole (0.37 g/ml), amphotericin B (0.4 g/ml), and isavuconazole (1.16 g/ml). Caspofungin, anidulafungin, fluconazole, and itraconazole had no activity.

“…Towards moving to a single nomenclature for fungi according to the International Code of Nomenclature for algae, fungi and plants (ICN), it is likely that the older generic name Togninia will persist for the whole genus. However, very recently the name Phaeoacremonium has been preferred over Togninia (Gramaje et al 2015), and new combinations have been proposed for Togninia species in Phaeoacremonium. In this regard, a new combination has been made for T. minima as Phaeoacremonium minimum (Gramaje et al 2015).…”

Togninia minima is the main fungal species associated with grapevine leaf stripe disease worldwide. This species is mainly known from its asexual state in nature; nevertheless, a biallelic heterothallic mating strategy has been confirmed for this species based on in vitro crossing studies. There are no data available on the incidence of an active sexual cycle within the populations of this species in many grapevine-producing countries as well as Iran. The possibility of a clandestine sexual cycle within the Iranian isolates of T. minima was evaluated by analysing the distribution and frequency of the mating-type alleles on a microspatial and a macrogeographical scales. Towards this aim, a total of 90 T. minima isolates were recovered from grapevines with esca disease from the vineyards in north and north-western Iran. A multiplex PCR method previously designed by authors was applied for simultaneous identification and determination of the mating-type alleles in T. minima populations. The results on the screening of mating-type alleles using multiplex PCR method revealed the mating-type identity of 77 isolates as Mat1-2 and 23 isolates as Mat1-1. Our results showed that both Mat1-1 and Mat1-2 isolates are present in a single vineyard and even on single vines. The distribution of mating-type alleles in the sampled area skewed from the 1 : 1 ratio (77 : 23); however, co-occurrence of both mating types in a single vineyard and even on single vines is suggestive for the presence of an active sexual cycle for T. minima in north-western Iran.
