The paper presents characteristics of cercosporoid fungal species from three genera, Cercospora, Passalora, and Pseudocercospora, 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 gathere...

Among the biotic factors that limit plant growth, population size, and reproduction, there is a mass appearance of microscopic parasitic fungi. The aim of the study was to determine the spectrum of the microfungi and the degree of leaf surface infection in the ragwort Senecio umbrosus , i.e., one of the Polish red data book species. In 2014–2016, studies on the diversity and dynamics of microfungi were carried out within its population on White Mt, southeastern Poland, where it grows in xerothermic habitats. During three seasons (6 collection series between May and October), 15 microfungal species were identified in total (1–9 species per one collection date, 9 species in each season). Only Coleosporium tussilaginis was present in all study dates, and it accounted for 30–100% of all records of the microfungi. Three hyperparasites were also identified on C. tussilaginis : Cladosporium uredinicola, Ramularia coleosporii , and Alternaria sp. The other taxa were found five ( Boeremia exigua, Leptosphaeria ogilviensis ), four ( Alternaria sp.), or three times ( Ascochyta compositarum, Periconia cookei ), but the majority of the microfungi were noted twice or only once, depending on meteorological conditions in a given growing season. Among common species of microfungi, we collected Ascochyta compositarum , which is a new species for Poland. Additionally, we found new fungus/host plant combinations for C. tussilaginis .
... Spośród grzybów patogenicznych występujących na I. parviflora można wymienić gatunki takie, jak: Cercospora campi-silii, Phyllosticta impatientis, Sphaerotheca balsaminae oraz Puccinia argentata. Wymienione są spotykane zarówno na rodzimych, jak i inwazyjnych gatunkach z rodzaju Impatiens (Chmura, 2014;Garibaldi i in., 2012;Świderska-Burek, 2015). Niestety te taksony, często podawane z nielicznych stanowisk w Polsce, mają marginalne znaczenie w procesie zamierania niecierpka drobnokwiatowego (Bomanowska i Adamowski, 2016). ...
Od wielu lat prowadzone są badania nad występowaniem i biologią niecierpka drobnokwiatowego (Impatiens parviflora DC.) w Wigierskim Parku Narodowym. Badany jest wpływ tego inwazyjnego gatunku
na elementy siedliska, właściwości gleby, a w ostatnich latach prace badawcze mają na celu określenie presji środowiska na ten gatunek. Jest bowiem możliwe, że populację I. parviflora mogą ograniczać czynniki biotyczne – fitofagi czy grzyby patogeniczne, ale także jeleniowate.
... Additionally, another cercosporoid fungus, Cercospora maianthemi Fuckel, has been noted on Maianthemum. It differs in much longer and wider conidiophores (up to 175 µm long and 7.5 µm wide) and conidia (up to 150 µm long and 8 µm wide), which are also multiseptate (2-22-septate) (Braun et al. 2014, Chupp 1954, Świderska-Burek 2015. ...
Two Zasmidium plant pathogens (Z. lythri and Z. subsanguineum) from different localities in Poland have been revised taxonomically based on herbarium specimens and on fresh collections. They are described and illustrated, and their distribution from the literature data in Poland and worldwide is compiled.

The critical revision of 59 Asteromella species occurring in Poland is presented, based primarily on specimens from Poland, as well as selected herbarial materials from France, Germany, Italy, Latvia, Lithuania, Romania, Slovakia, Switzerland and Ukraine. Some exsiccata, including types of Asteromella carlinae Petr., Asteromella ludwigii Petr., Asteromella ovata Thüm., Asteromella petasitidis Petr., Depazea agrimoniae Lasch, Mycosphaerella agrimoniae Syd., Phyllosticta borszczowii Thüm., Phyllosticta cicutae Lind, Phyllosticta eupatoriicola Kabát & Bubák, Phyllosticta pleurospermi Died., Phyllosticta salicina Kabát & Bubák, Phyllosticta senecionis-nemorensis Săvul. & Sandu, Phyllosticta wandae Namysł. were also studied. Each species is accompanied by the information pertaining to host spectrum, morphology of conidiomata, conidiophores, conidiogenous cells and conidia, distribution in Poland and globally, as well as information on synanamorphs and teleomorph, if present.
Two species, Asteromella moeszii Ruszkiewicz-Michalska & Mułenko spec. nov. on Pulmonaria obscura and Asteromella rupprechtii Ruszkiewicz-Michalska spec. nov. on Agrimonia eupatoria are described, based on Polish specimens. A new name, Asteromella huubii Ruszkiewicz-Michalska nom. nov., is proposed to replace Asteromella angelicae (Sacc.) Moesz ex Bat. & Peres. Nine Phyllosticta and two Depazea species were redisposed into Asteromella : Asteromella acetosae (Sacc.) Ruszkiewicz-Michalska, comb. nov., Asteromella adoxicola (Lasch) Ruszkiewicz-Michalska, comb. nov., Asteromella alnicola (C. Massal.) Ruszkiewicz-Michalska, comb. nov., Asteromella bacilloides (Dominik) Ruszkiewicz-Michalska, comb. nov., Asteromella prunellae (Ellis & Everh.) Ruszkiewicz-Michalska, comb. nov., Asteromella garbowskii (Gucevič) Ruszkiewicz-Michalska, comb. nov., Asteromella lysimachiae (Allesch.) Ruszkiewicz-Michalska, comb. nov., Asteromella populina (Fuckel) Ruszkiewicz-Michalska, comb. nov., Asteromella salicina (Kabát & Bubák) Ruszkiewicz-Michalska, comb. nov. Neotype of Asteromella bacilloides and a lectotype of Asteromella adoxicola are designated.
Nine species reported in the literature are not confirmed to occur in Poland; this includes two species that need to be recollected [ Asteromella scabiosae (Kalymb.) Vanev & Aa and Asteromella mali (Briard) Boerema & Dorenb.)], as dried specimens are scarce and deficient. Affinity of Asteromella confusa (Bubák) Petr. to Asteromella vs. Phoma is briefly disputed. New records and new data on the distribution of Asteromella species in Latvia, Poland, Slovakia, Switzerland and Ukraine are also provided. Three species are reported as new to Polish funga: Asteromella prunellae , Asteromella melampyrina and Asteromella moeszii.
