Leaf Curl Disease is amongst the supreme destructive diseases in peach throughout growing areas of the world, counting Pakistan. Symptoms parallel to those caused by Taphrina deformans were witnessed on leaves of peach in the entire growing areas of District Swat KPK Pakistan in 2018 and 2019. The isolates recovered from nearly all the affected leaves had white, cream to pinkish, circular, shiny, convex and pasty colonies with full margins on potato dextrose agar (PDA). Isolates brought a hypersensitive like reaction in peach (Prunus pursica) and tobacco (Nicotiana tabacum) 10 days after infiltration of leaves with different methods. Pathogenicity of illustrative isolates was confirmed by inoculation of peach (Prunus persica) twigs with a lightly suspension of each. Blast analysis of the ITS-sequences of representative isolates revealed their 99.72 % homology with those of Naganishia uzbakestaninsis, Cryptococcus adeliensis isolates present in GenBank. Partial sequences of 26S rRNA and RPB2 as well as their phenotypic characteristics verified the identity of the yeast isolates as Cryptococcus adeliensis. The Peach Leaf Curl Disease caused by Cryptococcus adeliensis appears to be a newly emerged disease to the stone fruit trees.
