MÜLLER J. (2010): Beitrag zur mykofloristischen Erforschung der Rost-, Brand und Falschen Mehltaupilze auf dem Králický Sněžník (Glatzer Schneeberg) und seiner Umgebung (Tschechische Republik).   [Králický Sněžník, Peronosporomycetes, Pucciniomycetes, Ustilaginomycetes, Microbotryomycetes]  Czech Mycology 62(1): 87-101   (published: 15th February, 2011)
  abstract   Between 1889 and 2001 a total of 17 species of downy mildews (Peronosporomycetes), 6 species of smut fungi (Ustilaginomycetes), 79 species (respectively varieties) of rust fungi (Pucciniomycetes), and 2 species of Microbotryomycetes were found in the Králický Sněžník and its surroundings. The investigated territory is delimited, a brief history of the research into these micromycetes is given, and a survey of 10 species of downy mildews, 2 species of smuts and 55 species of rusts found by the author is given. The results of the research were compared with historical records. The author found 34 species new to the territory concerned. On the other hand, he has not been able to verify the occurrence of 37 species recorded by previous mycologists, especially on the summit of Králický Sněžník.

DIETRICH W. (2005): Die Rost-, Brand- und Falschen Mehltaupilze des tschechischen Teiles des Erzgebirges (Krušné hory): erster Nachtrag.   [Peronosporales, Urediniomycetes, Ustilaginomycetes, Czech Republic, Krušné hory]  Czech Mycology 57(3-4): 257-273   (published: 10th February, 2006)
  abstract   In the years 2000-2004 several species of Urediniomycetes, Ustilaginomycetes and Peronosporales were found that are new to the Czech part of the Krušné hory Mts. A total of 57 taxa had not been pub­lished before. In this region 227species, subspecies and varieties are known to date. The distribution of selected species is shortly discussed and compared with the literature. Characteristic species of the more arid and warmer area of the south-east as well as the highest altitudes of the Krušné hory Mts. are enumerated. New hosts in the Czech Republic are the following: Calthapalustris subsp.procumbens for Puccinia calthae, Chaerophyllumhirsutum for Puccinia bistortae, Pinus x pseudopumilio for Coleosporium senecionis, Poa chaixii for Puccinia graminis and Phyteuma nigrum for Uromyces phyteumatum. The western and eastern parts of the Krušné hory Mts. have so far been investigated only to a minor extent.

MIRZAEE M.R., PANJEKEH N., SALARI M., ZARE R., PIRNIA M., SARANI S.A. (2021): Pustula lactucae sp. nov. (Albuginales, Oomycota), a new species causing white blister rust disease on Lactuca undulata.   [Asteridae, obligate biotroph, Peronosporomycetes, SEM, semiarid region.]  Czech Mycology 73(2): 151-162   (published: 22nd October, 2021)
  abstract   During 2016 and 2018, Lactuca undulata plants showing symptoms typical of white blister rust were collected in the province of South Khorasan, Iran. Phylogenetic analysis resolved the position of specimens in the genus Pustula. The specimens were characterised by oospore size and ornamentation, and size of secondary sporangia. In addition to morphology, phylogenetic analysis also suggests a new species for the genus distinct from other established Pustula species, which is described here as Pustula lactucae sp. nov. Scanning electron microscope illustrations are also provided.

MÜLLER J. (2015): Seltenere Falsche Mehltaupilze, Rost- und Brandpilze der Tschechischen und Slowakischen Republik. I. Teil Peronosporomycetes.   [Albuginales, Peronosporales, Czech and Slovak Republics]  Czech Mycology 67(1): 69-83   (published: 29th May, 2015)
  abstract   In this paper the author publishes the first part of a list of his collections of downy mildews (Peronosporomycetes), rusts (Pucciniomycetes) and smuts (Ustilaginomycetes and Microbotryomycetes) collected from 1949 to 2013 on the entire territory of the Czech and Slovak Republics. In this part the samples which he has identified to date, in total 120 species on 218 host plants, are presented.Of these species the most interesting are Knautia × posoniensis as a new host of Peronospora violacea, Plasmoverna pygmaea s. l. on Aconitum plicatum in the Hrubý Jeseník mountains as the only known locality in the Czech Republic, Peronospora dianthicola as a species new to Moravia and 29 host plants new to Moravia.

MÜLLER J., KOKEŠ P. (2008): Erweitertes Verzeichnis der Falschen Mehltaupilze Mährens und tschechisch Schlesiens.   [Peronosporales, host plants, numbers of localities, herbaria specimens, Moravia, Czech Silesia (east Czech Republic)]  Czech Mycology 60(1): 91-104   (published: 4th July, 2008)
  abstract   The paper represents an extended version of the Checklist of downy mildews of Moravia and Silesia, into which rusts and smuts were included, as published in Czech Mycology 56: 121–148, 2004.The current checklist includes 176 species and 514 combinations of downy mildews and host plants.For each species of downy mildew its host plants are specified and for every host plant the number of localities on which the downy mildew was recorded, including the year of the latest record and abbreviations of the herbaria in which the specimens are deposited. This checklist was elaborated mostly according to data published in literature.

  abstract   This checklist includes 736 taxa of downy mildews, rusts and smuts reported from Moravia and Czech Silesia, Czech Republic. There are 114 species parasiting oncrops and other cultivated plants. The list includes the frequency of occurrence, i. e. commonness or rarity of individual taxa. The work is based on literature data.

  abstract   In years 1849-2000 it has been found in Czech part of Krušné hory 101 species, subspecies and varieties of Uredinales, 21 of Ustilaginales and 45 of Peronosporales on 229 species of host plants. There are documented host plants, localities, years of findings and collectors. A historical survey of myc of loristical research of these micromycetes is presented. All species has been filed into typical plant formations. Characteristic species for highest mountain sites are enumerated. Statements of literature are compared with actual data. The new hosts in Czech republic are following: for Peronospora myosotidis Myosotis nemorosa, for Coleosporium senecionis and Puccinia silvatica Senecio hercynicus, for Melampsoridium betulinum Betula nana.

MÜLLER J. (1995): Australischer Rostpilz Puccinia lagenophorae auch in der Tschechischen und Slowakischen Republik und in Ungarn.   [Puccinia lagenophorae, Senecio vulgaris, Czech Republic, Slovak Republic, Hungary]  Czech Mycology 48(2): 161-167   (published: 25th September, 1995)
  abstract   In the 1990–1994 Puccinia lagenophorae Cooke (both aecia and telia) has been found for the first time on Senecio vulgaris in Czech Republic (at 9 localities), Slovak Republic and Hungary. A description is given of the rust fungus incl. its markings estimated by SEM. The overwintering of aecial stage was observed in Brno. The host plants are compiled and the possible way of introduction of the mentioned rust into Europe is discussed.

HORÁKOVÁ J., SKALICKÝ V. (1989): Contribution to the ecology of Peronospora violacea Berk.  Česká Mykologie 43(1): 13-29   (published: 6th February, 1989)
  abstract   Peronospora violacea Berk. is an obligate floricolous Peronospora. All floricolous parasitic fungi of the family Peronosporaceae belong to the genus Peronospora Corda, probably to only one evolutional complex; of the foliicolous parasitic species, Peronospora destructor (Berk.) Casp. is their closest relative. It is impossible to distinguish individual microspecies within P. violacea Berk. on the basis of host plants; three new host species were found. The systemic infection of the Knautia species by both indirect and direct methods (replanting, histological proof of mycelium) was demonstrated. The data on oospores were corrected and completed. Basing on the revision of all materials preserved in the Czechoslovak public herbarium collections, a map of distribution of this species in Czechoslovakia was compiled and evaluated. A special chapter is devoted to the problems of nomenclature.

ČAČA Z. (1982): Present trends in the world phytopathological research.  Česká Mykologie 36(2): 65-71   (published: 15th May, 1982)
  abstract   Vararia granulosa (Fr.) Laurila is a name which cannot be applied to the fungus for which it is now commonly used. Fries (1838, 1874) considered the element representing our Vararia only a marginal part of his broad concept of Grandinia granulosa (Pers. ex Fr.) Fr. As there is no legitimate name for the fungus in question, Vararia borealis Pouz. spec. nov. is proposed for it here.
