abstract
The article was presented at the 7th International Congress of Mycology Division (IUMS-94) in Praha, July 3-8, 1994. The rust fungi are damaging for many important crops. Many rust species possess complicated life cycle. Up to now the most effective method has appeared to be the production of rust resistant cultivars and biological control on integrated basis. Therefore the thorough knowledge of taxonomy, biology and ecology of not only economically important rusts but also potentially harmful rust species on wild plants is highly desired. Especially in tropics and subtropics the rust taxonomy and ecology is known imperfectly. The author informs briefly on steps concerning the improvement of rust systematics organized at the rust symposia at International Mycological Congresses (IMC) in Tampa (USA) 1977, Tokyo, 1983 and Regensburg (BRD) 1990. In the international cooperation it should be prepared, through computers and videodisc technology, the “World database for plant rust fungus species”. Most limiting factors are: to find leaders in relatively rich and major institutions and funds from national and international organizations.
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.

abstract
In three archives in Prague and in Klatovy micromycetes from the atmosphere, archive documents, walls and shelves were studied. Altogether 88 species, mostly representatives of the Moniliales as well as Mucorales orders, Penicillium and Aspergillus species prevailed. The following species were among the most frequently isolated: Penicillium cyclopium, Cladosporium herbarum, C. cladosporioides, Alternaria alternata, Aspergillus niger, Penicillium chrysogenum, Rhizopus arrhizus and Aspergillus versicolor. The number of species rose with increasing relative humidity and deteriorated hygienic conditions in the storage areas. Fungi with weaker cellulolytic activity, utilizing bookbinding glues, were also verified to contribute to the destruction of archival documents. From a hygienic perspective, the presence of pathogenic species Aspergillus fumigatus and Rhizomucor pusillus is significant for archive staff.

abstract
The brown rust of couch grass (Puccinia persistens var. persistens) in Bohemia hibernates on Agropyron repens growing in regularly cut fodder plantations. Under suitable climatic conditions (warm temperatures and precipitation), the inoculum spreads rapidly. Transfer to wheat cultivars Triticum aestivum cv. Mironovská 808 and Little Club was confirmed by infection trials and differences in urediospore wall thickness.

abstract
In the area of the secondary evolutionary gene center of wheat (the Mediterranean) as well as in the regions of the primary gene centers the “graminicolous facies“ of the wheat stem rust, Puccinia graminis subsp. graminis seems to play a significant role. Similarly as in the Mediterranean also in Asia the “ruderal facies“ is combined with that of sexual hybridization on barberry (“montane facies“). Future studies envisage the following: 1) study of the rust ecology in the evolutionary centers, determination of geographic distribution of the individual physiologic races and populations and investigation into the urediospore long distance spread; 2) in search after the gene sources of resistance using of stem rust resistant grass populations indigenous to the evolutionary centers is preferred; 3) to protect natural ecosystems embracing barberry within the evolutionary centers and thus ensure the existence and further development of wild and cultivated grass populations possessing a high degree of nonspecific (general) stem rust resistance or tolerance.
URBAN Z., MARKOVÁ J. (1983): Ecology and taxonomy of Puccinia graminis Pers. in Czechoslovakia. Česká Mykologie 37(3): 129-150 (published: 28th July, 1983)
abstract
Puccinia graminis in Czechoslovakia was studied principally on collections from localities with more or less natural occurrence of Berberis vulgaris. Main interest was paid to the ecology and morphology of its urediospores. According to urediospore size and shape four different morphologic groups were recognized. They characterize individual populations or specialized forms. Inoculation experiments document approximately the host range. In Czechoslovakia we recognize 2 subspecies of stem rust. P. graminis subsp. graminis embraces cerealicolous specialized forms together with some large-spored specialized forms on wild grasses: f. sp. secalis and f. sp. Agropyron repens–Dactylis glomerata. P. graminis subsp. graminicola Urban is mainly graminicolous, with races and populations having small urediospores. Somewhat special position in the subspecies graminicola is occupied by three populations that parasitize the following hosts: Anthoxanthum odoratum, Deschampsia cespitosa and Phleum pratense. A further study of epiphytotics pattern should not overlook the very conspicuous existence of large-spored stem rust populations on wild grasses.

abstract
Czechoslovak mycology from 1945 to 1975 is reviewed with a focus on the development of practical and popular mycology, including the activities of the Czechoslovak Mycological Society and the Czechoslovak Scientific Society for Mycology. Cooperation between these organizations and their impact on public education and exhibitions is emphasized, with mention of the permanent exhibition “Fungi” in Brno as a unique achievement.
URBAN Z., MARKOVÁ-ONDRÁČKOVÁ J. (1975): Inoculation experiments with Puccinia bromina Eriks. 2. Česká Mykologie 29(3): 135-139 (published: 1975)
abstract
Inoculation experiments with Puccinia bromina Eriks., var. bromina urediospores collected from Bromus sterilis were unsuccessful on several grass species. However, aeciospores from Symphytum cordatum and S. tuberosum caused infections on Bromus erectus and B. ramosus subsp. benekenii. This supports the existence of two biological varieties: the non-alternating var. bromina and the heteroecious var. paucipora.

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.

abstract
Extensive growths of Armillaria mellea rhizomorphs were observed in timber supports in a coal mine shaft in Kladno, Bohemia. Laboratory and in situ experiments on wood protection were conducted. The fungicides Lastanox Q and Universal proved effective. Imperfect fungi such as Trichoderma viride, Aspergillus niger, and Cladosporium avellaneum also showed inhibitory effects on rhizomorph development.

abstract
The life cycle of the brown rust of Couch grass from 3 Bohemian localities was studied. It was stated that there are at least 2 different physiologic races of the rust. One of them parasitizing Agropyrum × apiculatum in the mountains České středohoří is obligatorily heteroecious alternating with Thalictrum minus. In this respect it differs from 2 other collections on Agropyrum repens (originating from Central and South Bohemia) in which host alternation does not take place. Moreover, last mentioned races differ in their pathogenicity from the obligatorily heteroecious rust. For all urediniospore collections infection type on 33 grass species, 26 wheat varieties, 20 rye varieties, 1 barley variety and 4 wheat-couch grass hybrids and 2 wheat-rye hybrids was stated. Some species of Bromus and Couch grass were compatible. Wheats and their hybrids showed necrotic spots only. A part of rye plants inoculated produced uredinia of the susceptible type of infection.
