Fungi of the genus Ramularia in the Słowiński National Park

Abstract

In the years 1996-98 and 2001, the occurrence of fungi of the genus Ramulania in 11 plant associations of the Słowiński National Park (north-western Poland) was investigated. The plant associations included: Angelico-Cirsietum oleracei, Betulo pendulae-Quercetum roboris, Carici arenariae-Empetretum nigri (CaEn), Elymo-Ammophiletum (EA), Empetro nigri-Pinetum, Filipendulo-Geranietum, Helichryso-Jasionetum litoralis, Myrico-Salicetum auritae (MSa), Phragmitetum australis (Pa), Ribeso nigri-Alnetum, and Vaccinio uliginosi-Betulelum pubescentis. A total of 37 species of Ramularia were found. Of them, R. galli was newly found in Poland, and R. archangelicae, R. calcea, R. chamaedryos, R. cynarae, R. didymarioides R. lactea, R. rhaetica, R. schulzeri R. tanaceti and R. triboutiana were earlier infrequently recorded in this country. Eight Ramularia taxa were found on plants earlier not reported to be their hosts, i. e., Ramularia chaerophylli (on Chaerophyllum temulum), R. lamii var. lamii (Galeopsis tetrahit), R. inaequale (Hieracium laevigatum, H. sabaudum and Hypochoeris radicata), R. schulzeri (Lotus uliginosus), R. grevilleana var. grevilleana (Potentilla erecta), R. uredinis (Pucciniastrum vaccinii z Vaccinium uliginosum), R. lactea (Viola palustris and V. tricolor) and R. veronicae (Veronica arvensis). Most species of Ramularia occurred in the MSa (18), and least in EA (1), CaEn (l), and Pa (1).
