\nSYMPTOMS<\/strong>
\nChlorosis of the leaves and leaf dwarfing are the first noticeable symptoms
\non the tree, followed by leaf drop showing a regressive death of the leaves
\nyoung stems and adult branches. At first glance, the difference between the
\naffected and healthy branches by the difference in pigmentation of the leaves and of their
\nsize. On closer inspection, you can see the cankers on the stems and the
\nbranches, a cross-section of the affected branches shows the cankers
\nV-shaped. With the passage of time, we can observe the continuous deterioration that causes
\nSardiniella urhana on Celtis australis to defoliate large areas of the tree
\nlosing photosynthetic surface area and causing the death of large branches, which leads to
\nfear for the safety of people in the cities where Celtis australis
\nare planted as alignment trees.

\nE-F10 \u00b5m
\nDESCRIPTION<\/strong>
\nConidioma: picnidial, unilocular, ostiolado, glabro, piriforme, 210-320 x 140-200 \u00b5m,
\nangular textured outer wall, 40-50 \u00b5m thick, composed of five to seven layers
\nof brown polyhedral cells in the eternal layers to subhyaline cells in the
\ninternals. Conidiogenous cells proliferate percurrently, forming in the apex
\ninconspicuous, hyaline, cylindrical annulations. Conidium solitary, initially hyaline,
\nbrown and bicellular at maturity, with a medial septum, thick-walled, rough, ellipsoidal to
\novoid, 19-26 x 9-15 \u00b5m. Colonies on PDA and MEA 2%, grow 80mm after 7 days, velvety texture with irregular margins, white turning green
\nDark when mature, dark grey reverse, NOTES
\nIn Palma de Mallorca, Sardiniella urbana has been isolated from Celtis australis and on
\nCeltis occidentalis, from both affected parts and healthy stems behaving as
\nendophytic organism. We have found Sardiniella urbana in saplings, trees,
\njuveniles, adults and individual trees, this being a very widespread disease in
\nMallorca and throughout the Meditophranco basin.
