abstract
Erysiphe azaleae, a powdery mildew growing on deciduous Rhododendron species is reported from the Slovak and Czech Republics. A detailed description is given and its distribution in Europe is discussed.

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.
URBAN Z., MARKOVÁ J. (1985): Ecology of brown rust of couch grass, Puccinia persistens, in Bohemia. Česká Mykologie 39(4): 225-233 (published: 8th November, 1985)
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.
CAGAŠ B., MARKOVÁ J. (1985): Spezializierung des Rostes Puccinia poae-nemoralis Otth auf Poa pratensis L. und Poa palustris L. Česká Mykologie 39(1): 39-43 (published: 1985)
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., MARKOVÁ J. (1984): Ecology and evolution of Puccinia graminis Pers. Česká Mykologie 38(2): 65-95 (published: 15th May, 1984)
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.
MARKOVÁ J., URBAN Z. (1977): To the knowledge of the brown rust of couch grass in Bohemia and Moravia. 2. Česká Mykologie 31(2): 72-80 (published: 1977)
abstract
This is a continuation of a previous paper (Čes. Mykol. 30: 90–105, 1976). Literature data, own results as well as ecologic and historic features are discussed to support the reasons for taxonomic treatment of brown rusts of couch grass and wheat: Puccinia persistens Plow. subsp. persistens var. persistens; P. persistens var. triticina (Eriks.) Urban et Marková (leaf rust of wheat); P. persistens subsp. agropyrina (Eriks.) Urban et Marková.

abstract
A morphometric study of teliospores of brown rust from Agropyrum spp. and wheat reveals statistically significant differences between populations. Differences in teliospore dimensions support taxonomic distinctions among rust forms.
