PYTHIUM ULTIMUM VAR. ULTIMUM, A NEW RECORD FROM PAKISTAN

A Pythium species without sporangia and zoospores, having terminal as well as intercalary oogonia with a few papilla, monoclinous but occasionally diclinous antheridia and aplerotic oospores was isolated from the rhizosphere of date palm. This species is identified as P. ultimum var. ultimum Trow and appears to be a new record from Pakistan.
