sp. nov. a New Fungal Pathogen Causing Stem Cankers and Twig Dieback of Fruit Trees.

Stem cankers and twig dieback were the most serious disease of fig () and loquat () noticed in a survey of fruit tree orchards in the Fars Province, Iran. Isolates of were consistently recovered from symptomatic fig and loquat trees. Phylogenetic analyses of multiple nuclear loci, internal transcribed spacer regions (ITS) of rDNA, RNA polymerase II subunit 2 (), and translation elongation factor 1-α (), combined with morphological observations, revealed that isolates could be referred to a still unknown taxon, which was formally described as sp.
