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.

HORÁKOVÁ J., SKALICKÝ V. (1989): Contribution to the ecology of Peronospora violacea Berk. Česká Mykologie 43(1): 13-29 (published: 6th February, 1989)
abstract
Peronospora violacea Berk. is an obligate floricolous Peronospora. All floricolous parasitic fungi of the family Peronosporaceae belong to the genus Peronospora Corda, probably to only one evolutional complex; of the foliicolous parasitic species, Peronospora destructor (Berk.) Casp. is their closest relative. It is impossible to distinguish individual microspecies within P. violacea Berk. on the basis of host plants; three new host species were found. The systemic infection of the Knautia species by both indirect and direct methods (replanting, histological proof of mycelium) was demonstrated. The data on oospores were corrected and completed. Basing on the revision of all materials preserved in the Czechoslovak public herbarium collections, a map of distribution of this species in Czechoslovakia was compiled and evaluated. A special chapter is devoted to the problems of nomenclature.

abstract
Die Autoren geben eine Übersicht der auf Astragalus s. 1. parasitierenden Peronospora-Arten an. Auf Grund des Studiums von Herbarmaterial halten sie die Peronospora astragali Syd. und P. astragalina Syd. für dieselbe Art, für die der Name P. astragalina Syd. vorgeschlagen wird. Es wurden 15 Belege der Peronospora auf Astragalus cicer untersucht, welche nach Vergleich mit der Peronospora auf Astragalus penduliflorus zur Peronospora phacae Gäum. eingereiht wurde. Es handelt sich um eine neue Art für die CSSR und Ungarn. Das geringe Material der Peronospora auf Astragalus onobrychis, in Ungarn gesammelt, erlaubte keine genaue taxonomische Einreihung. Die Autoren beschreiben und bilden eine in der ČSSR gefundene Peronospora auf Astragalus exscapus ab. Nach der Untersuchung zweier Belege wurde sie vorläufig zur Peronospora astragalina Syd. angereiht.

abstract
The author distinguishes three ecological groups of spring downy mildew species in the family Peronosporaceae: 1) those with systemic infection via persistent mycelium in vegetative organs, 2) those with systemic infection via fruits or seeds, and 3) those with dispersive infection initiated from oospores. Special attention is paid to Peronospora bulbocapni and its unusual sporulation in 1962.

JAMALI S. (2020): First report of Paraconiothyrium fuckelii (Didymosphaeriaceae, Pleosporales), causing stem canker of Rosa hybrida, from Iran. [Dothideomycetes, fungal disease, internal transcribed spacers, Iran mycobiota, pathogenicity.] Czech Mycology 72(1): 71-82 (published: 29th May, 2020)
abstract
In spring 2016, stem canker symptoms were observed on most Rosa hybrida plants in greenhouses of Kermanshah Province in Western Iran. Initial symptoms of the disease were brown necrotic lesions, mostly 8–10 mm long, on stems. The lesions eventually depressed and expanded to a long ellipse, resulting in yellowing and wilting of the foliage. Fungal colonies resembling those of Paraconiothyrium species were obtained from diseased tissues. Based on morphological and DNA sequence analysis of the internal transcribed spacers ITS1 and ITS2 and the 5.8S gene the fungal isolates were identified as Paraconiothyrium fuckelii. This is the first report of stem canker disease caused by this species in Iran. Pathogenicity tests were carried out on potted Rosa hybrida plants and detached branches under controlled conditions. Pathogenicity tests demonstrated that the fungus is able to infect and cause canker symptoms on inoculated branches of healthy plants after four weeks. The pathogen was re-isolated from all inoculated plants after observation of the symptoms, thus meeting Koch’s postulates.
PARVEEN S., WANI A.H., BHAT M.Y., KOKA J.A. (2016): Biological control of postharvest fungal rots of rosaceous fruits using microbial antagonists and plant extracts - a review. [biological control, postharvest diseases, microbial pesticides, rosaceous fruits] Czech Mycology 68(1): 41-66 (published: 1st February, 2016)
abstract
This article aims to give a comprehensive review on the use of microbial antagonists (fungi and bacteria), botanicals and compost extracts as biocontrol agents against different pathogenic fungi causing postharvest fungal rots in rosaceous fruits which shows that they can play an important role in the biomanagement of fungi causing rot diseases. Plant extracts reported in the literature against pathogenic fungi indicate that they can act as a good biological resource for producing safe biofungicides. However most of the work has been done under experimental conditions rather than field conditions. There is still a need for research to develop suitable formulations of biofungicides from these microbial biocontrol agents and plant extracts. The review reveals that extensive ecological research is also required in order to achieve optimum utilisation of biological resources to manage various postharvest diseases of fruits.

abstract
The mycological material from an epizootic on Acyrthosiphon pisum Harris on alfalfa was evaluated. Pathogenicity of two isolates of Erynia neoaphidis Remaudière et Hennebert 1980 was tested and compared with the pathogenicity of the same fungus applied via infected aphids. The death rate of infected aphids was primarily influenced by relative humidity, regardless of whether the fungal material came from culture or from dead infected hosts.

abstract
Academician Ctibor Blattný, one of the founders of Czechoslovak phytopathology, long-time vice-chairman and honorary member of the Czechoslovak Scientific Society for Mycology, celebrated his 80th birthday on September 8, 1977. His biography and scientific, popularization and pedagogical activities were previously evaluated in this journal by A. Pilát. His extensive publication activity is evidenced by selections of works published by the author of this article on the occasion of his 70th and 75th birthdays. Blattný made significant contributions to various areas of agricultural research and especially to plant protection. He conducted pioneering work on hop diseases, notably Pseudoperonospora humuli, and published a major monograph in 1926. He remained devoted to hops, contributing to forecasting diseases and pests, and emphasized the importance of negative selection for removing diseased plants. His discovery in 1942 of a new biotype of Synchytrium endobioticum, the cause of potato wart disease, was of global significance and confirmed later abroad.

abstract
The importance of mixed infections of cultivated plants by viruses and pathogenic fungi is analyzed both from theoretical and practical points of view. The course of root rots caused by pathogenic fungi in various virus-infected hosts is described as an example to demonstrate these relationships. The causes of the altered disease syndrome in the root system are discussed.
