Abstract Alien tree species have been introduced to Europe and often used as roadside trees. Currently, preference is given that are adapted urban climate drier conditions. Native epiphytic lichens local species; however, little known whether a shift toward more alien trees would affect the diversity of within cities. We considered three genera common in Hamburg (Germany) Acer, Tilia, Quercus, ...

Mycosphaerella punctiformis, the type species of the genus Mycosphaerella, is epitypified by material collected on Quercus robur in The Netherlands. The teleomorph is described in planta, and the Ramularia anamorph, for which the new name R. endophylla is proposed, and the Asteromella spermatial state are characterized in vitro. Sequence data of the nuclear ribosomal DNA are presented and analy...

The Tilia genus (linden, lime) comprises about 30 deciduous tree species native to North America, Europe, and Asia. They are often used along roads in parks because of their aesthetic value urban landscapes. During surveys 2017–2018 Istanbul, Turkey, typical viral disease symptoms such as foliar mosaics, mottling chlorotic ringspots, deformations were observed on spp. (Figs. 1-3). Forty-six lea...
