In the present article, two new mitosporic spccies are introdued, namely: Cercospora fraxinicola Ershad, sp. nov. on Fraxinus rotundifolia and Ramularia rubicola Ershad, sp. nov. on Rubus caesicus.

Two Phyllactinia species have been associated with powdery mildew on leaves of ash trees (Fraxinus) in Eurasia, fraxinicola U. Braun & H.D. Shin from Southeast Asia and fraxini (DC.) Fuss Europe. Non-native are planted urban greeneries both Europe Asia, but so far, the two not reported same area. Our molecular analysis European material consisting 55 specimens 15 countries confirmed absence...

The species diversity of culturable endophytic fungi was studied in the leaves and twigs symptomatic asymptomatic Fraxinus excelsior trees. Endophytic mycobiota dominated by Ascomycota species, with Pleosporales (44.17%) Diaporthales (23.79%) endophytes being most frequently observed tree samples. number isolates richness varied depending on sampling date (May October) tissue location. Of 54 id...

In Lithuania, the dieback of European ash (Fraxinus excelsior L.), caused by alien ascomycete Hymenoscyphus fraxineus, started in mid-1990s, resulting a large-scale decline F. and its dominated forest habitats. Nevertheless, recent inventories show presence several hundred hectares naturally regenerated stands. We used seven sites three planted progeny trials to collect leaves, shoots, roots, s...

Phylogenetic relationships of the Uncinula lineage, which is the basal group in the genus Erysiphe, were investigated with 167 sequences of nuc ITS1-5. 8S-ITS2 and the 28S rDNA regions. Backbone tree analyses with six datasets and two tree-constructing methods revealed that the Uncinula lineage is divided into seven distinct clades. Clades 1-5 each contained a representative powdery mildew spec...

Novel species of fungi described in this study include those from various countries as follows: Argentina , Colletotrichum araujiae on leaves, stems and fruits Araujia hortorum . Australia Agaricus pateritonsus soil, Curvularia fraserae dying leaf Bothriochloa insculpta millisiae yellowing tips Cyperus aromaticus Marasmius brunneolorobustus well-rotted wood, Nigrospora cooperae necrotic Heterop...
