Petrakia Leaf Blotch of Sycamore Maple The anamorphic fungus Petrakia echinata was identified as causal agent of a leaf blotch disease of sycamore maple (Acer pseudoplatanus) trees at two localities in Austria between 2003 and 2004. Although this fungus has been known as leaf pathogen on sycamore maple for a long time, it is not mentioned in reference books of forest pathology in Europe. The characteristics of Petrakia echinata and the disease caused by this fungus are therefore described and illustrated. No common name has previously been designated for this infectious leaf disease. It is thus suggested to refer to it as "Petrakia leaf blotch of sycamore maple" (German: "Petrakia-Blattbraune des Bergahorns") in the future.
