Abstract
<p>The paper presents characteristics of cercosporoid fungal species from three genera, <em>Cercospora</em>, <em>Passalora</em>, and <em>Pseudocercospora</em>, occurring in Poland and deposited in Polish herbaria or to be expected due to the occurrence of their host plants in the Polish flora. The physiographic literature, but primarily own collections, as well as those gathered in the national herbaria, were the object of the revision.</p><p>This monograph provides morphological descriptions, lists of hosts and distribution in Poland and worldwide as well as detailed illustrations for 41 species. Dichotomous keys for identification of fungi parasitizing hosts from different plant families were prepared within the individual fungal genera.</p><p>The present study represents a compilation of 115 cercosporoid species, of which 63 are reported from Poland and another 6 were doubtful and excluded. The fungi parasitize 221 taxa of host plants from 131 genera and 47 families, out of which 158 taxa from 94 genera and 29 families have been actually found in Poland. Fourteen species described in this book belong to <em>Cercospora apii</em> s. l. Nine quarantine species are listed, from which only three have been published so far.</p><p>This study will be helpful to mycologists, plant pathologist, and Polish plant protection services for identification purposes of the fungi concerned.</p>
Highlights
Świderska-Burek / Cercosporoid fungi of PolandCercosporoid fungi belong to anamorphic fungi, previously called mitosporic fungi or Fungi imperfecti
Knowledge about the occurrence and distribution of most species has been provided by studies of wild-growing plants, including those collected during research in natural conditions in interesting, natural, legally protected areas [41–54]
Passalora, described by Fries in 1849, was the first genus introduced for cercosporoid fungi, followed by Cercospora established in 1863 by Fresenius with Cercospora penicillata (Ces.) Fresen. [= C. depazeoides (Desm.) Sacc.] as type species
Summary
Cercosporoid fungi (hyphomycetes) belong to anamorphic fungi, previously called mitosporic fungi or Fungi imperfecti. Symptoms of the diseases observed on infected host plants are nonspecific and very often similar to symptoms caused by species belonging to different genera and frequently to other taxonomic groups, e.g. water moulds (Peronosporales), and even to some groups of Ascomycota Another problem that appears in studies of anamorphic fungi is the fact that the presence of the sexual stage has not yet been affirmed in most known species. Knowledge about the occurrence and distribution of most species has been provided by studies of wild-growing plants, including those collected during research in natural conditions in interesting, natural, legally protected areas [41–54] The objective of this monograph was a critical study of cercosporoid fungi from Poland aiming at improvement of the general knowledge of the fungal groups concerned. At the beginning of the previous decade, i.e. at the time of commencement of the current research, only 30% of species hitherto known in our country were cited in the worldwide literature
