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.
KOKEŠ P., MÜLLER J. (2004): Checklist of downy mildews, rusts and smuts of Moravia and Silesia. [plant-parasitic fungi, occurrence, regions of the Czech Republic, Peronosporales, Sclerosporales, Urediniomycetes, Ustilaginomycetes] Czech Mycology 56(1-2): 121-148 (published: 12th August, 2004)
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.
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.
