??Cladosporium rot?? on ??Bosc?? pear fruit during cold storage causes significanteconomic losses and has been reported in recent years in the productive valleys of Río Negroand Neuquén. The species involved were not determined. During 2016-2017, ??Bosc?? pears(Pyrus communis) in cold storage chambers exhibited external brownish black circular spotscaused by Cladosporium spp. The objective of this work was to determine the Cladosporiumspecies that caused the above mentioned symptoms. The morphological and molecular analysesof the partial sequence of the actin gene (ACT) supported the identification. Cladosporiummacrocarpum, Cladosporium subtilissimum and Cladosporium floccosum were determined asthe species involved in the disease. Although Cladosporium has been reported to cause pearrot, this is the first report to identify these species as causal agents of this fruit disease.
