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.

  abstract   Cleistothecia of Podosphaera leucotricha (Ell. et Ev.) Salm. occur annually in Czechoslovakia as early as mid-June. Ascospore differentiation is influenced by weather. Some differentiation continues after overwintering, but ascospores were not found to germinate.

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.

NOVOTNÝ D., LUKÁŠ J., BROŽOVÁ J., RŮŽIČKOVÁ P. (2019): Comparison of the occurrence of fungi causing postharvest diseases of apples grown in organic and integrated production systems in orchards in the Czech Republic.   [Malus domestica, organic production, integrated production, Neofabraea, Penicillium.]  Czech Mycology 71(1): 99-121   (published: 28th June, 2019)
  abstract   During the years 2013–2015, the occurrence of fungi causing postharvest diseases of apples was evaluated in three apple orchards with integrated and organic production systems in the Czech Republic. The postharvest disease fungi were more frequently recorded in fruits from organically cultivated apple trees (average 29.97%) than those from integrated production (17.67%). This difference is statistically significant. Neofabraea, Penicillium, Alternaria and a sterile grey mycelium were the most frequently recorded taxa in apples grown in organic and integrated production systems. There were also significant differences in the frequency of occurrence of the most frequent fungal taxa between years. In 2013 and 2014, Neofabraea was the most frequently isolated genus in both cultivation systems, whereas in 2015, Penicillium was the most frequently recorded genus also in both cultivation systems, which was likely caused by the low precipitation in the 2015 growing season.

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.

APINE I., BANKINA B., NIKOLAJEVA V., TOMSONE S. (2013): Powdery mildew on Rhododendron caused by Erysiphe azaleae in Latvia.   [Erysiphe azaleae, Rhododendron, Latvia]  Czech Mycology 65(1): 113-123   (published: 10th June, 2013)
  abstract   In 2002 a fungus causing powdery mildew on Rhododendron in Latvia was discovered and identified as Erysiphe azaleae. The powdery mildew has since then been observed on leaves and seed pods of deciduous azaleas as well as evergreen rhododendrons, although the disease is more common on taxa of deciduous azaleas. Development of mature chasmothecia has been noticed at every location where the disease was detected. The distribution area of E. azaleae is expanding gradually from the south-west and central regions to the north and east parts of Latvia. It has been suggested, that climate change and large-scale plant import favour this process. To our knowledge, Latvia is so far the farthest north-easternmost site where E. azaleae has been detected.

  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.

Colloquium „Fungi as Model Organisms in Research and Biotechnology - III“ Olomouc, Czech Republic, 2 September 2005.  Czech Mycology 57(3-4): 307-323   (published: 10th February, 2006)
  abstract   The colloquium was a continuation of the previous scientific meetings that took place in Olomouc in 1999 and 2002 (Czech Mycology 52: 139-178, 2000 and 55: 103-149, 2003). It was organised by the Commission for Experimental Mycology of the Czechoslovak Microbiological Society and the Czech Scientific Society for Mycology together with the Institute of Biology, Faculty of Medicine of Palacký University, Olomouc. The aim of the colloquium was to provide a platform for a broad discussion on experimental mycology in all branches of basic and applied research. Besides two plenary lectures, 8 short communications and 8 posters were presented. In total 32 researchers from the Czech and Slovak Republics took part in the colloquium and discussed various topics important for the further development of experimental mycology. Abstracts of the contributions are given here.

  abstract   Tradice mezinárodních mykologických kongresů není stará. První byl v roce 1971 v anglickém Exeteru. K vrcholným vědeckým setkáním tohoto typu nelze přiřazovat již delší dobu pořádané Sjezdy evropských mykologů. Druhý mezinárodní mykologický kongres se konal ve dnech 27. VIII. až 3. IX. 1977 v prostorách University of South Florida v Tampě. Zúčastnilo se ho více než 1200 specialistů ze 43 zemí.

  abstract   The study investigates the effect of various organic compounds on the germination of conidia of Erysiphe graminis f. sp. hordei in vitro. Vitamins and growth stimulators were tested to understand their role in obligate parasite cultivation. The results suggest that some compounds stimulate while others inhibit conidial germination.
