HÝSEK J., TEMPÍROVÁ Z. (1986): The occurrence of Ascochyta Lib. and Didymella Sacc. on the leaves of cereals in Czechoslovakia.  Česká Mykologie 40(2): 86-94   (published: 10th May, 1986)
  abstract   Ascochyta avenae, Ascochyta tritici and Didymella sp. were identified on oats, wheat and barley leaves collected in 10 localities near Tachov (West-Bohemian region) in the spring of 1984. In our material yellow-and-brown lesions on oats were marginated dark red and contained irregularly dispersed pycnidia of Ascochyta avenae (Petr.) Sprague et Johns, [syn. Pseudodiplodia avenae (Petr.) Petr.]. Pycnidia were sized in average 139.5 x 134.25 µm, pycnospores 24.5 x 6.2 µm, having 1–2 septa. Infected spots of wheat and barley leaves were spindle-shaped, dark brown marginated. Ascochyta tritici Hori et Enjoji identified in wheat had pycnidia 138.5 x 130 µm in average, pycnospores 15.5 x 4.6 µm, normally having one central septum, two or even three septa were rare. In barley perithecia of fungus Didymella sp. were found 128 x 147 µm in average, with asci 55 x 11.5 µm and ascospores 15.5 x 6.2 µm, with one central septum. The above-mentioned fungi were cultivated on maltose-dextrose agar at 20–25°C, for 14 days under UV-light (365 nm).

MOUBASHER A.H., ABDEL-SATER M.A., SOLIMAN Z.S.M. (2018): Diversity of yeasts and filamentous fungi in mud from hypersaline and freshwater bodies in Egypt.   [fungal diversity, alkalinity, Wadi El-Natrun, lakes, Ibrahimia Canal, River Nile, molecular characterisation, ITS]  Czech Mycology 70(1): 1-32   (published: 26th January, 2018)
  abstract   The diversity of yeasts and filamentous fungi in muds from hypersaline alkaline lakes of Wadi ElNatrun and fresh water of the Nile River and Ibrahimia Canal was evaluated. The mean pH of saline water mud was 9.21, but fresh water mud registered 8.07. A total of 193 species (two varieties were distinguished in two of them) belonging to 67 genera were recovered from both muds investigated on DRBC (55 genera, 164 species), DG18 (36 genera, 117 species) and MY50G (23 genera, 76 species) media. From these, 17 species assigned to 12 genera were yeasts and 176 species and 2 varieties assigned to 55 genera were filamentous fungi. The highest numbers of fungal propagules were recovered on DRBC from freshwater mud, while the lowest on MY50G from saline water mud. Yeasts constituted a small proportion of all propagules from the two mud types on all three media, whereas filamentous fungi were the major component. However, freshwater mud samples yielded higher numbers of yeast genera and species using all three media. Candida was common in freshwater mud and rare in saline water mud, while Meyerozyma and Rhodotorula were infrequent in both muds. The remaining yeast species were recovered from freshwater mud only. Aspergillus (46 species) was the most common genus of filamentous fungi encountered in all samples, ranging in frequency from 39.82% to 96.62%; A. terreus, A. flavipes and A. niger dominated in both types of mud. Cladosporium (9 species), Fusarium (8 species), Penicillium (18 species) and Scopulariopsis (7 species) were encountered in both types of mud. Notably, 47 filamentous species were isolated only on the media with lower water activity (DG18, MY50G).

ISMAIL M.A., ABDEL-HAFEZ S.I.I., HUSSEIN N.A., ABDEL-HAMEED N.A. (2013): Contribution to physiological and biochemical diagnostics of Fusarium taxa commonly isolated in Egypt.   [Fusarium, taxonomy, physiological features, acetylmethylcarbinol, diagnostic]  Czech Mycology 65(1): 133-150   (published: 10th June, 2013)
  abstract   Fusarium isolates belonging to 24 species and 8 sections were subjected to 11 growth, physiological and biochemical tests (166 isolates). All species were able to grow on 25% Glycerol nitrate agar (G25N), Mannitol medium, Czapek iprodione dichloran agar (CZID) and Dichloran chloramphenicol peptone agar (DCPA). Growth rate, colony colour and reverse on G25N and CZID were promising diagnostic criteria for separating species within sections. The growth rate and reverse on Mannitol agar was diagnostic not only for separation of F. oxysporum from F. solani, but also for separation of many other Fusarium species treated. The ability to grow on Tannin-sucrose agar could distinguish some species of sections Liseola and Sporotrichiella. Acid production on Creatine-sucrose agar distinguished some species of section Liseola and F. trichothecioides of section Discolor. Acetylmethylcarbinol production revealed for the first time that all isolates of F. subglutinans can produce this substance, while most remaining isolates lacked this ability. Tests for peroxidase, urease and pyrocatechol oxidase proved to be very useful. The phosphatase enzyme seems to be common in Fusarium species and therefore it is only diagnostic for F. camptoceras (negative results). Some physiological features could be used as criteria to distinguish some sections or species within the same section.

PAŽOUTOVÁ S., KOLÍNSKÁ R. (2003): Relationship of Cerebella to Epicoccum and their closest relatives among Dothideales.   [Cerebella andropogonis, Epicoccum, phylogeny, rDNA sequence]  Czech Mycology 54(3-4): 155-160   (published: 23rd May, 2003)
  abstract   The Czech isolate of Cerebella sp. was confirmed as C. and ropogonis, as its RAPD patterns were identical to those of Australian and African isolate of this species. Also, rDNA (ITS1-5.8S-ITS2) sequences of African C. and ropogonis and the Czech isolate (AJ306620 and AJ400905) were identical except for a single transition A-G at position 47 of ITS1. Comparison of these quence with databases yielded 24 closely related sequences with 96.5-98.9 % identity to Cerebella. The highest similarity was found between Cerebella and Epicoccum nigrum/ Phoma epicoccina isolates, two other related groups were : Phoma herbarum, P. medicaginis, Phomopsis sp., and P. glomerata/Ampelomyces sp.

Belonia incamata is new for the Šumava Mts. Diploicia canescens, Parmelia glabra and Parmelia revoluta, species which had been missing in the Czech Republic for a long period of time, were recently rediscovered. Other included lichens are very rarely found and are known from only a few localities in the Czech Republic. A large number of recordsare from the Protected Landscape Area Křivoklátsko, in the Rakovník District.

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.
