Celtis species are widely distributed in Turkey and has 4 species. One of them is
C. glabrata (Steven ex Planchon) and is found in the Lakes region. A fungal
disease was commonly observed on Celtis leaves with irregular, large, black spots
on both sides and velvety apperance on the lower side. Disease incidence was so
high that all the leaves of the trees showed symptoms with varying degrees. As a
result of the microscopic examination of the lower leaf surfaces, the fungus was
identified as Sirosporium celtidis (Biv., Bern. Ex Sprengel) M. B. Ellis. Since C.
glabrata is not grown in forest nurseries in our country, the fungus is not
economically important. However, it can cause defoliation and poor growth of
trees in natural ecosystems.
