2. MATERIAL AND METHODS<br />
SDÜ ORMAN FAKÜLTESİ DERGİSİ<br />
Distribution, identification and pathology <strong>of</strong> individual species <strong>of</strong> powdery<br />
mildew have been studied on set <strong>of</strong> 240 examined samples collected on amenity<br />
trees and woody plants in parks in the CR within 2004 - 2008. Leaves infected with<br />
powdery mildew were collected in North and South Moravia and East Bohemia.<br />
Identification was provided according Braun (1987, 1995) and Paulech C. (1995),<br />
taxonomy was corrected by Takamasu (2007). Identification was made according<br />
to morphological features; critical findings were confirmed by H.D. Shin, new<br />
species as Erysiphe elevata and E. azaleae were confirmed on the bases <strong>of</strong> DNA.<br />
Herbarium specimens are deposited at Herbarium <strong>of</strong> Department <strong>of</strong> Forest<br />
Protection and Wildlife Management, Faculty <strong>of</strong> Forestry and Wood Technology.<br />
3. RESULTS, DISCUSSION<br />
There were identified 30 different species <strong>of</strong> powdery mildew on woody plants<br />
belonging to following genera: Erysiphe, Microsphaera, Phyllactinia,<br />
Podosphaera, Sawadaea, Sphaerotheca, Uncinula, Uncinuliella (Tab. 1). From this<br />
number <strong>of</strong> identified Erysiphales is Phyllactinia roboris reported as a missing<br />
species actually and Erysiphe euonymi-japonici (Vienn.-Bourg.) U. Braun & S.<br />
Takamatsu is known only from herbarium specimen collected in 1941; recent<br />
records are missing. Nearly 11 species <strong>of</strong> reported powdery mildews can be termed<br />
alien, although origin <strong>of</strong> several species is not clear. Newly recorded species are<br />
Erysiphe arguata, E. azaleae, E. elevata, E. flexuosa, Erysiphe palczewskii,<br />
Erysiphe syringae, Erysiphe vanbruntiana var. sambuci-racemosae.<br />
