Up until 2017, Dothistroma septosporum has only been detected and molecularly confirmed to cause DNB in Slovakia. Here, we report the detection of Dothistroma pini at six localities around Slovakia, representing different plantation types. Four pine species (Pinus sylvestris, P. nigra, P. mugo and P. jeffreyi) were confirmed as hosts of D. pini in Slovakia, of which only P. mugo has been previously reported as host in Slovakia.

The occurrence of Phyllactinia guttata on Platanus is discussed and questioned.}, keywords = {}, pubstate = {published}, tppubtype = {article} } A global survey of the spread of the Platanus powdery mildew, Erysiphe platani, has been carried out. E. platani teleomorph formation was recorded in countries where the fungus anamorph has been present for several years. The first findings of chasmothecia were recorded in Austria, Czech Republic, France, Italy and Slovakia. New records of E. platani (including the teleomorph) were found in Belgium, Croatia and Denmark. The occurrence of this fungus in Sweden and in two countries of North Africa (Algeria and Morocco) was confirmed. Descriptions of morphological features, illustrations, and worldwide distribution of E. platani are provided. Herbarium collections of powdery mildews on Platanus spp. were re-examined and revised. The occurrence of Phyllactinia guttata on Platanus is discussed and questioned. |
