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.
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.
MARKOVÁ J. (1976): To the knowledge of the brown rust of couch grass in Bohemia and Moravia.1. Česká Mykologie 30(2): 90-105 (published: 1976)
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.
URBAN Z. (1967): The taxonomy of some European graminicolous rusts. Česká Mykologie 21(1): 12-16 (published: 1967)
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.
URBAN Z. (1966): On the taxonomy of Puccinia recondita Rob. ex Desm. s. l. Česká Mykologie 20(1): 38-44 (published: 1966)
abstract
Taxonomic distinctions within the Puccinia recondita complex are discussed using electron microscopy and morphology. The author argues that P. bromina, P. holcina, and P. triseti are valid separate species, not varieties of P. recondita.
