PAULECH C., PAULECH P. (1996): Occurrence of phytopathogenous micromycetes of the order Erysiphales in the national park Slovenský raj. [Erysiphales, genera and species, host plants] Czech Mycology 49(2): 107-118 (published: 13th October, 1996)
abstract
Fifty-five species of phytopathogenous micromycetes of the order Erysiphales from the following genera were detected on investigated territory: Sphaerotheca (12 species), Podosphaera (4), Erysiphe (22), Blumeria (1), Microsphaera (10), Sawadaea (1), Uncinula (2), Phyllactinia (2) and Oidium (1). For individual species the biometric variability of conidia dimensions, cleistothecial diameter, ascus and ascospore dimensions are given. The detected species were parasitizing on 129 host plant species.
BENADA J. (1974): The susceptibility and the resistance of the tissues of cucumber and squash to powdery mildew Sphaerotheca fuliginea in the dependence on oxidation reduction potencial and pH. Česká Mykologie 28(1): 44-53 (published: 1974)
abstract
The resistance of cucumber and squash to powdery mildew (Sphaerotheca fuliginea) was estimated based on conidia germination and mycelium formation on detached leaves kept on moist filter paper under high humidity. No direct relationship was found between oxidation-reduction potential (ORP), pH, and susceptibility. However, two susceptibility zones were identified: cotyledons with pH ~6 and ORP ~+50 mV, and older leaves with pH ≥7 and negative ORP. Similar results were found in squash tissues.
ONDRÁČKOVÁ E., SEIDENGLANZ M., ŠAFÁŘ J. (2019): Effect of seventeen pesticides on mycelial growth of Akanthomyces, Beauveria, Cordyceps and Purpureocillium strains. [entomopathogenic fungi, growth inhibition, Lecanicillium, Isaria, fungicides, insecticides, herbicides.] Czech Mycology 71(2): 123-135 (published: 1st November, 2019)
abstract
The effect of fungicides, herbicides and insecticides on mycelial growth of entomopathogenic fungi Akanthomyces muscarius, Beauveria bassiana, Cordyceps fumosorosea and Purpureocillium lilacinum were tested under laboratory conditions. Fungicides containing the active ingredients carboxin & thiram, dimethomorph & mancozeb, mancozeb & metalaxyl-M, boscalid & pyraclostrobin, mancozeb, metalaxyl-M & fludioxonil and herbicides with active ingredients pendimethalin, pethoxamid, chlorotoluron and pendimethalin & imazamox statistically significantly inhibited the mycelial growth of all tested fungi (20.4–100% and 14.9–100% inhibition). Insecticides did not significantly inhibit the mycelial growth of Akanthomyces and Purpureocillium strains but active ingredients tau-fluvalinate, pirimicarb and acetamiprid inhibited the mycelial growth of Beauveria strains (22.6–30% inhibition). The mycelial growth of Cordyceps strains was faster in the presence of insecticides than in controls.
PASTIRČÁKOVÁ K., PASTIRČÁK M. (2013): Powdery mildew (Pseudoidium sp.) found on Chelidonium majus in the Czech Republic and Slovakia. [Erysiphaceae, Erysiphe s. str., morphology, Papaveraceae] Czech Mycology 65(1): 125-132 (published: 10th June, 2013)
abstract
The find of a powdery mildew (Pseudoidium sp.) on Chelidonium majus in the Czech Republic and Slovakia is reported. Disease symptoms and morphological characteristics of the anamorph are described. No teleomorph was observed. Morphology and distribution of other powdery mildew species on hosts of the Papaveraceae are discussed. We point out the need for phylogenetic analysis of three closely related species (Erysiphe cruciferarum, E. hylomeci, and E. macleayae) and determination of its relationship to the fungus on C. majus.

[powdery mildew, Neoerysiphe galeopsidis, Oidium subgenus Striatoidium, Stachys, host range] Czech Mycology 60(2): 251-264 (published: 27th February, 2009)
abstract
On the basis of re-examinations of herbarium collections, species of the genus Stachys as host plants of the powdery mildew species Neoerysiphe galeopsidis in Slovakia and the Czech Republic were verified. A detailed description, illustrations, the host range and the distribution of this fungus are given.
NIKOLCHEVA L.G., BÄRLOCHER F. (2002): Phylogeny of Tetracladium based on 18S rDNA. [Tetracladium, 18S rDNA, Leotiales, Erysiphales, Onygenales] Czech Mycology 53(4): 285-295 (published: 3rd October, 2002)
abstract
Complete sequences of 18S rDNA of seven strains of Tetracladium were determined. The following species were included: T. apiense, T. furcatum, T. maxilliforme, T. setigerum (one strain each) and T. marchalianum (3 strains). Sequence homology among the 7 strains was >98%. The closest published match (NCBI database) to the Telracladium sequences is one by Bulgaria inquinans (homology 95-96%). Phylogenetic analysis placed the Tetracladium complex in the vicinity of the Ascomycete orders Onygenales, Erysiphales and Leotiales.
Colloquium "Fungi as Model Organisms in Research and Biotechnology", Olomouc, September 14th, 1999. Czech Mycology 52(2): 139-178 (published: 20th April, 2000)
abstract
The colloquium was organized by the joint Commission for Experimental Mycology of the Czechoslovak Microbiological Society and the Czech Scientific Society for Mycology. The purpose of the colloquium was to provide a platform for a broad discussion on the use of fungi as model organisms in both basic and applied research. The programme of the colloquium was divided into four parts dealing with the following topics: phytopathology, biotechnology and ecology, physiology and biochemistry, and medical mycology. Each topic was opened with a plenary lecture (30 min.), followed by short communications (10 min.) and accompanied by poster presentations. Besides four plenary lectures, 15 short communications and 21 posters were presented. In total 38 researchers took part in the colloquium, at who discussed various questions of importance for experimental mycology until late in the evening. Abstracts of the contributions are given here.
PAULECH C., HERRERA S., FORNET E. (1993): Phytopathogenic micromycetes of the family Erysiphaceae distributed in Cuba. Česká Mykologie 46(3-4): 303-314 (published: 25th August, 1993)
abstract
The results of investigation of phytopathogenic micromycetes of the family Erysiphaceae occurring in phytocenoses of Cuba and Isla de la Juventud are summarized in this paper. They are dealing mainly with their host range, distribution and their morphological characteristics. Mentioned group of the fungi was detected on 78 plant species belonging to 62 genera and 16 families. They parasited mainly on species of the family Fabaceae (on 22 species from 13 genera) and Asteraceae (on 15 species from 14 genera), further on Euphorbiaceae (9 species from 6 genera), Malvaceae (6 species from 5 genera), Cucurbitaceae (4 species from 3 genera), Boraginaceae (3 species from 2 genera), as well as on species of the families Anacardiaceae, Balsaminaceae, Bixaceae, Brasicaceae, Caricaceae, Lythraceae. Rosaceae and Zygophyllaceae (only one species of the host plants). The fungi of the family Erysiphaceae occurred only in anamorphous stage. There is a growing tendency in the intensity of occurrence of mentioned group of micromycetes in Cuba. They are strongly parazitized by the mycoparasite Ampelomyces quisqualis Ces., too.
KUTHAN J. (1992): Mycoflora of large-scale greenhouse plantation of salad cucumbers. Česká Mykologie 46(1-2): 1-32 (published: 1st April, 1993)
abstract
In the course of the years 1988–1991 the author used to visit large-scale greenhouses at Paskov near Ostrava (NE Moravia, Czechoslovakia) and surveyed not only the abundant growth of particularly higher fungi there, but in 1989 he tried to summarize the weight of biomass of the most frequent species. The results of the observation of biomass, frequency, abundance and phenology are presented in the tables. Altogether 95 macrofungi taxons, 1 species of Hyphomycetes and 1 species of Myxomycetes were recorded and they are given in the systematic summary, potentially with comments.

STANĚK M. (1984): Microorganisms in the hyphosphere of fungi. I. Introduction. Česká Mykologie 38(1): 1-10 (published: 10th February, 1984)
abstract
The surface and immediate surroundings of fungal hyphae affected by their activity is termed the „hyphosphere“. Differences between microorganisms colonizing the hyphosphere and those colonizing a substrate is termed „hyphosphere effect“. The more extensive area of fungal effect on substrate, on the surface and surroundings of fruit-bodies, i.e. the environment affected by the activity of fungi is termed „mycosphere“. The nomenclature proposed is in agreement with the classification of the phytosphere of higher plants. The brief literary survey presents data on incidence of microorganisms in hyphosphere and on their importance, taking into account the results obtained in the Czechoslovak research institutions.
