ABSTRACT<br />
Agata WOŁCZAŃSKA. The Ramularia species in Poland. Monogr. Bot., Vol. 95, 154 pp., 2005.<br />
The Ramularia species represent a big and interesting group among parasitic Hyphomycetes. In<br />
Poland have been collected so far 115 species: one on fern, three on 5 species of rust fungi and the<br />
remaining ones on angiosperms (on 301 species belonging to 38 families). The most common are:<br />
R. geranii var. geranii, R. grevilleana var. grevilleana, R. inaequale and R. urticae. But more than 40%<br />
of all the species occur very seldom (they are known from 1-5 stands). The following examples belong<br />
to this group: R. asplenii, R. asteris, R. keithii, R. minutissima and R. rhaetica.<br />
The biggest number of parasitic species are noted on the representatives of Asteraceae (17 species),<br />
Scrophulariaceae (9), Rosaceae (7) and Polygonaceae (7).<br />
The best explored regions in Poland are situated in the south and south-east part of the country:<br />
Kraina Karpat Zachodnich, Kraina Południowomazowiecko-Podlaska and Kraina Dolnośląska.<br />
The Ramularia species are facultative saprotrophs. Anamorphs parasite on host plants and fungi,<br />
but known teleomorphs, belonging to Mycosphaerella genus, develop on plants remains. The vegetative<br />
season indicates their occurrence limits. They start to grow in April, the biggest number of species<br />
are collected in summer and the end of vegetation in November, is the signal to stop producing<br />
spores. At that time they form sclerotia, perithecia or pass the winter as mycelium and conidia.<br />
Key words: anamorphic fungi; Hyphomycetes; Ramularia; distribution; Poland<br />
