Switzerland, United Kingdom, etc. (Ale-Agha et al., 2004; Vajna et al., 2004;
Pastirčáková et al., 2006; etc.). Is it widespread in plantation in towns in the CR
now (Ale-Agha et al., 2004; Palovčíková et al., 2007). Some latest records are
origin from Bulgaria (Denchev et al., 2008), Romania and from Italy (own
observations, not published). Reasons of spreading are the same – trade with plant
material and favorable climate. Some other species on Catalpa Erysiphe catalpae
Simonyanis was not reported from CR up to date. This species is confused with E.
elevata in some European countries frequently (Ale-Agha et al., 2004).
Horse chestnut mildew E. flexuosa (Peck) U. Braun & S. Takam (syn.
Uncinuliella flexuosa (Peck) U. Braun.) on Aesculus spp., was firstly reported from
Europe by Ale-Agha et al. (2000), Ing and Spooner (2002) and others. It is a
common powdery mildew species infecting Aesculus trees in North America
(Glawe and Dugan, 2007) and Europe - Croatia, France, Germany, Lithuania,
Poland, Romania, Serbia, Slovakia, Slovenia, Switzerland, Ukraine, and United
Kingdom (Braun, 1987; Heluta and Voytyuk, 2004; Pricop & Tănase, 2007;
Zimmermannová-Pastirčáková et al., 2002; Kiss et al., 2004). From the Czech
Republic is reported by Zimmermannová-Pastirčáková et al. (2002) and
Palovčíková et al. (2007).
Some other new species for the CR is Erysiphe arcuata U. Braun, V. P. Heluta
and S. Takam. on hornbeams Carpinus betulus, previously (Palovčíková et al.,
2007) reported this species as Erysiphe carpinicola (Hara) U. Braun & S. Takam.
Braun et al. (2006) re-examined European powdery mildew collections on C.
betulus (including the anamorph Oidium carpini) from Germany, Hungary and
Ukraine, and described them as a new species E. arcuata, contrary to previous
records. Pastirčaková et al. (2008) reports this species from Slovakia. Previous
records of E. carpinicola from Hungary (Vajna, 2006a) and from Poland
(Wołczanska, 2007; Piatek, 2004) probably regarded as E. arcuata as well.
Caragana powdery mildew Erysiphe palczewskii Braun & Takamatsu (syn.
Microsphaera palczewskii Jacz.) is native to Asia, however it has been introduced
into many European countries (Gelyuta and Gorlenko, 1984; Braun, 1995; Gelyuta
and Minter, 1998; Braun et al., 2006; Vajna, 2006b). During the summer of 2006
were severe Erysiphe palczewskii recorded in the CR into area of Central
Moravia as well (Lebeda et al., 2008).
Erysiphe syringae Schwein. (syn. Microsphaera syringae (Schwein) H. Magn.)
and Erysiphe vanbruntiana var. sambuci-racemosae (U. Braun) U. Braun & S.
Takamatsu is common species across the CR actually and it was recorded in 2005
(Palovčíková et al., 2007).
Erysiphe euonymi-japonici (Vienn.-Bourg.) U. Braun & S. Takamatsu is
reported from herbarium specimen No. M-0016258, collected in 1931 at Piskoř by
Prague and specimen is deposited in powdery mildew collection at München,
Germany (Botanische Staatssammlung München), although recent records are
missing.
