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.

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.

abstract
The occurrence and pathogenicity of European populations of oat crown rust (Puccinia coronata var. avenae) and effectiveness of resistance donors are analysed. High virulence variability is observed. Most effective resistance genes are Pc 39, Pc 48, Pc 50, Pc 55, Pc 58, and Pc 59. Least effective are Pc 35, Pc 40, Pc 45, Pc 46, Pc 47, and Pc 54. Suitability of these genes for breeding is discussed.

abstract
The differences in the virulence of the crown rust populations of Puccinia coronata Corda var. coronata f. sp. festucae in Czechoslovakia were studied by field infestation of selected clones of Festuca pratensis Huds. at 8 sites under various environmental conditions in 1978–1979. The results, complemented by greenhouse tests on the offspring of the clones, confirmed the existence of at least two rust populations with different virulence levels. This underlines the necessity of testing resistant plant varieties at different localities or using mixed populations of the rust in breeding for resistance.

abstract
Analysis of the host plant range of the important parasite of Festuca pratensis Huds. — the crown rust Puccinia coronata Corda var. coronata — showed that this is indeed the graminicolous form of this rust species. Positive infection was observed in 24 grass species out of 174 tested from the Poaceae family. The most significant hosts with practical importance in the spread of this rust include Festuca pratensis Huds., Festuca gigantea (L.) Will., Cynosurus cristatus L., Lolium remotum Schrank, Lolium rigidum Gand., and Lolium temulentum L. The highest number of host plants was found among the tribes Festuceae and Phalarideae.

abstract
Based on revision of Czechoslovak graminicolous rust fungi, the author proposes the re-establishment of certain species concepts and nomenclatural changes in taxa of Puccinia. A summary of these changes is provided, including several varieties and subspecies, such as P. bromina var. paucipora and P. graminis var. stakmanii.

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.
URBAN Z. (1991): Broad and narrow species concept in graminicolours rust fungi. Česká Mykologie 45(3): 99-102 (published: 31st October, 1991)
abstract
The mankind is now facing the first-class target: the protection and conservation of the gene pool of all organisms. This concerns plants, animals and saprophytes (destruents) as economically useful as well as injurious and harmful ones like rust fungi. The detailed knowledge of the gene pool of both host plants and their biotrophic pathogens is one of the important prerequisites for effective integrated management of plant rusts. Based on the global, rough taxonomic treatment of graminicolous rusts we are not able to get a detailed picture about the gene pool of rust species concerned. Therefore, taking into account the global species concept, we have to discover the inner biological and ecological variability, which became evident as various infraspecific taxa or individual narrow species.
BENADA J. (1990): Less common symptoms of cereal diseases by two parasitic fungi. Česká Mykologie 44(4): 243 (published: 26th November, 1990)
abstract
Two unusual symptoms of cereal diseases caused by Ustilago nuda and Puccinia persistens var. triticina are described. U. nuda formed smut sori on barley leaf blades instead of ears. P. persistens developed uredia in a ring pattern on wheat leaves transferred to a glasshouse.

abstract
Populations of the rust fungus Puccinia poae-nemoralis isolated from Poa pratensis and Poa palustris represent special forms highly specialized to their host species. Resistant cultivars and ecotypes may be used in breeding programs. Morphological differences between the two forms are minimal, but paraphyses wall thickness varies.
URBAN Z. (1974): Concerning taxonomic concept and nomenclature of some cereal rust fungi. Česká Mykologie 28(2): 80-83 (published: 1974)
abstract
The author discusses Chochrjakov’s proposal of names for several cereal rust fungi, such as Puccinia persistens f. sp. tritici and P. coronifera, and contrasts them with his own taxonomic and nomenclatural concepts. He recommends using names like Puccinia perplexans var. triticina for wheat brown rust, P. coronata var. avenae for oat rust, and subdivisions of P. graminis for cereal and grass rusts. He argues for the use of names that best reflect the pathogen’s morphology and ecology.
