A new species and a new record of Diatrypaceae from Iran

Abstract

Two species of Diatrypaceae (Xylariales) are described and illustrate from Iran. Diatrypella iranensis from dead branches of Quercus brantii is described as a new species based on both morphology and molecular sequence data. It differs from other members of the genus on the basis of stroma morphology and ascus and ascospore sizes. Molecular data of the ITS rDNA region show that the new species is a sister taxon of Diatrypella quercina. Cryptovalsa ampelina is described from dead branches of Juglans regia and is a new record from Iran. This study is the first in a series that investigate the diversity of Diatrypaceae from Iran.

Fungal diversity notes 253–366: taxonomic and phylogenetic contributions to fungal taxa

“…Norphanphoun et al (2015) designated the epitype for Seimatosporium rosae, the type species of Seimatosporium. Mehrabi et al 2015). The genus was characterized by eutypoid ascostromata, polysporous asci and allantoid ascospores (Spooner 1981;Vasilyeva and Stephenson 2005;Trouillas et al 2011).…”

“…Cryptovalsa ampelina is the most studied species in Cryptovalsa (Nitschke 1867; Mostert et al 2004;Vasilyeva and Stephenson 2005;Luque et al 2006;Martín et al 2009;Trouillas et al 2010;Trouillas et al 2011;Mehrabi et al 2015). Notes: Cryptovalsa ampelina is a pathogen of grapevines (Vitis vinifera L.) and is abundant on pruned canes and necrotic wood of living plants (Mostert et al 2004;Luque et al 2006;Trouillas et al 2010;Pitt et al 2013a).…”

Diatrypella heveae Senwanna, Phookamsak & K.D. Hyde (Diatrypaceae, Xylariales): a new record for the Neotropics

“…Nitschke as the type species, to accommodate stromatic members of Sphaeriales (Rao 1964), it currently comprises 146 records (Index Fungorum 2020). Diatrypella verruciformis is characterized by conical or truncated ascostromata, pulvinate or discoidal, generally delimited by black lines on host tissues, and perithecia ascoma with ostiole umbilicate or sulcate, asci multisporic, cylindrical, with long pedicels, and ascospores ovoid or allantoid, hyaline or light-yellow (Vasilyeva and Stephenson 2005;Mehrabi et al 2015;Shang et al 2017 (Vieira et al 2012); D. amorae Viégas, D. exigua G. Winter (Mendes and Urben, 2020); D. caatingae D.A.C. Almeida, Gusmão & A.N.…”

Cryptosphaeria Canker of Populus nigra Caused by Cryptosphaeria pullmanensis, a New Threat to Poplar Industry in Iran

“…pullmanensis have been described and reported from oak and walnut based on a combination of morphological and molecular data (Mehrabi et al. ; Raoufi et al. ).…”

“…Very recently, three additional species namely Diatrypella iranensis, Cryptovalsa ampelina and Cr. pullmanensis have been described and reported from oak and walnut based on a combination of morphological and molecular data (Mehrabi et al 2015;Raoufi et al 2016). Considering the economic importance of the poplar industry in Iran, extensive sampling and isolation were carried out from cankered tissues on poplar trees in West Azarbaijan Province in 2014.…”
