Podosphaera dipsacacearum. [Descriptions of Fungi and Bacteria].
A description is provided for Podosphaera dipsacacearum, a terrestrial fungus, obligately parasitic on species of the Dipsacaceae, but not causing a serious disease resulting in death of the plant. Some information on its substrata, habitats, dispersal and transmission and conservation status is given, along with details of its geographical distribution (North America (USA (Washington)), Asia (Afghanistan, Armenia, Azerbaijan, Iran, Iraq, Israel, Kazakhstan, Kyrgyzstan, Lebanon, Pakistan, Tajikistan, Turkey, Turkmenistan, Uzbekistan), Europe (Bulgaria, former Czechoslovakia, France, Germany, Greece, Hungary, Italy, Netherlands, Poland, Romania, Russia (Rostovskaya oblast), Spain, Turkey, Ukraine, UK, former Yugoslavia)). Since Dipsacus species are sometimes regarded as invasives, there may be potential to use P. dipsacacearum as part of an integrated biological control programme.
