Abstract :
Since the publication of the latest
monograph of powdery mildews by Braun and Cook
in 2012, no comprehensive revision has been done
to check the accuracy of the hitherto recorded
species of the genus Erysiphe in Iran. In this study,
we present a taxonomic revision of Erysiphe sect.
Uncinula in Iran using morphological traits of
voucher specimens and ITS-LSU rDNA sequence
analysis. Thirty-eight voucher specimens were
obtained from the University of Guilan Mycological
herbarium (fungarium, GUM) and the Fungus
Reference Collection of Herbarium Ministerii
Iranici Agriculturae (IRAN), as well as newly
collected specimens during 2019–2021, were
examined morphologically. The ITS sequences were
generated for 26 selected specimens, and the LSU
sequences were generated for 16 specimens. Two
ITS sequences of E. paradoxa (OM574846 and
OM574845), as well as ITS and LSU sequences of
E. celtidis (OM574855 and OM574834,
respectively), were sequenced for the first time in
this study. Precise morphological observations and
molecular analyses of Iranian specimens changed
the number of accepted species of Erysiphe sect.
Uncinula from six taxa in 2009 to 10 taxa in 2021.
All species identified from Iran are here described
and illustrated. A key to species of Erysiphe sect.
Uncinula in Iran is also provided.
