Abstract
<em>Pistacia integerrima</em> is a deciduous tree species belonging to the family Anacardiaceae. The plant possesses numerous phytochemicals of ethno-medicinal importance. In a routine mycological survey carried out from July 2013 to June 2014, leaves of <em>P. integerrima</em> were found infected with fungi causing rust and blight diseases. The morphological and microscopic observations revealed three fungi, namely <em>Skierka himalayensis</em>, <em>Pestalotiopsis</em> sp., and <em>Pileolaria pistaciae</em>, which were found to cause rust and blight diseases. One new species of rust fungi, namely <em>Skierka himalayensis</em> sp. nov., and <em>Pestalotiopsis</em> sp. are reported for the first time from India. The detailed descriptions and illustrations of these three phytopathogenic fungi are provided in this paper.
Highlights
During a routine mycological survey In India carried out from July 2013 to June 2014, two rust and a blight disease on P. integerrima caused by different fungal pathogens were noticed
The specimens infecting leaves of Pistacia integerrima were collected in different seasons, : rust samples during the prerainy (May–July) and winter (October–December) season, while leaf blight samples in postrainy (August–October) season
Bhardwaj and Sharma [10] conducted a survey for the fungal diseases of Pistacia integerrima in district Solan, Himachal Pradesh, India during 1989–1990 and reported four foliar diseases, including leaf spot and yellow and brown leaf rust caused by Cercospora megaspermae L

Pistacia integerrima is reported to suffer from a number of fungal diseases. During a routine mycological survey In India carried out from July 2013 to June 2014, two rust and a blight disease on P. integerrima caused by different fungal pathogens were noticed.
