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.
AL-ARAIMI S.H., AL-HATMI A.M.S., ELSHAFIE A.E., AL-BAHRY S.N., AL-WAHAIBI Y.M., AL-BIMANI A.S., DE HOOG S. (2019): New record of Aureobasidium mangrovei from plant debris in the Sultanate of Oman. [Ascomycota, Dothideales, ITS, LSU, morphology, physiological characteristics, saprotroph.] Czech Mycology 71(2): 219-229 (published: 19th December, 2019)
abstract
Aureobasidium mangrovei was isolated from plant debris in Muscat, Sultanate of Oman. The isolate was characterised and compared with related species of this genus for its growth, colony morphology, and micromorphology. Molecular analysis of the LSU and ITS rDNA supported final identification of the isolate. Our record is the second find in the world and the first in the Sultanate of Oman. DNA sequences of the isolated strain showed 99% (ITS) and 100% (LSU) similarity, respectively, with the sequences of the type isolates from Iran, as well as similar growth and colony morphology. A complete microscopic characterisation, which was not described for the Iranian strain, was made. The Iranian strains were isolated from saline habitats of the protected Hara forests, while our strain was isolated from the leaves of freshwater habitats. A comparison of growth characteristics of both strains under different conditions is provided.
KOUKOL O., KOVÁŘOVÁ M. (2007): Autecology of Scleroconidioma sphagnicola particularly in Šumava National Park (Czech Republic). [Scleroconidioma sphagnicola, Dothideales, microsclerotia, coniferous litter, Sphagnum] Czech Mycology 59(1): 111-123 (published: 28th June, 2007)
abstract
The anamorphic fungal species Scleroconidioma sphagnicola was repeatedly isolated from spruce and pine litter needles in Šumava National Park. The morphology of thirteen strains of this fungal species was compared; oxidative enzymes and possible parasitism on Sphagnum in vitro were tested. Our results showed that all of the strains differed from the original description in only one characteristic – microsclerotia lacked conidiogenous cells on their surface. All strains produced laccase and peroxidase, eleven strains produced polyphenol oxidases. Inoculation of Sphagnum species resulted in only negligible colonisation. We suppose that Scleroconidioma sphagnicola in the studied area does not parasite on Sphagnum. This conclusion is supported by the fact that strains of Scleroconidioma sphagnicola were isolated from needles lying among Sphagnum, but no diseased plants were found.Results of our previous experiments with Scleroconidioma sphagnicola dealing with decomposition of spruce litter needles and competition with other fungal species are summarised.
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.
KOCOURKOVÁ J. (1999): Lichenicolous fungi from the Czech Republic. 1. Weddellomyces xanthoparmeliae Calatayud et Nav.-Ros. [Dothideales, Dacampiaceae, Weddellomyces xanthoparmeliae Calatayud et Nav.-Ros., lichenicolous fungi, taxonomy, Xanthoparmelia] Czech Mycology 51(2-3): 179-184 (published: 25th May, 1999)
abstract
The parasitic lichenicolous fungus Weddellomyces xanthoparmeliae Calatayud et Nav.-Ros., recently described from Xanthoparmelia cf. protomatra (Calatayud et Navarro-Rosinés 1998) is now reported also from central Europe from the Czech Republic. It has been collected in several localities on Xanthoparmelia conspersa (Ehrh. exAch.) Hale and X. somloensis (Gyelnik) Hale. Weddellomyces xanthoparmeliae occurs in great quantity in all the Czech and Moravian localities and therefore it seems possible to find it without difficulties also in other warm areas in situations with rather xerothermic habitats where the hosts are commonly present.
KOCOURKOVÁ J., BERGER F. (1999): Polycoccum minutulum (Dothideales, Ascomycetes), a new lichenicolous fungus on Trapelia placodioides. [Lichenicolous fungi, Ascomycetes, Dothideales, Polycoccum, Trapelia placodioides, flora of Austria, flora of the Czech Republic] Czech Mycology 51(2-3): 171-177 (published: 25th May, 1999)
abstract
A new lichenicolous fungus species, Polycoccum minutulum Kocourková et F. Berger is described from CentralEurope. Thecombination of features of this species, such as discoloration of infected parts of the host, the formation of galls, the size of the halonate spores provided with verruculose epispore and also the host Trapelia placodioides Coppins et P. James, distinguishes it from other species of the genus Polycoccum Sauter ex Körb.

[New records, lignicolous Pyrenomycetes, Dothideales, Sordariales, Czech and Slovak Republics] Czech Mycology 49(3-4): 207-227 (published: 23rd May, 1997)
abstract
The paper deals with 12 lignicolous species of Pyrenomycetes; Actidium hysterioides Fr., Actidium nitidum (Cooke et Ellis) Zogg, Capronia borealis M. E. Barr, Capronia chlorospora (Ellis et Everh.) M. E. Barr, Cercophora caudata (Currey) Lundq., Farlowiella carmichaelina (Berk.) Sacc., Gloniopsis curvata (Fr.) Sacc., Mytilinidion rhenanum Fuckel, Pseudotrichia mutabilis (Pers.: Fr.) Wehm., Rebentischia massalongii (Mont.) Sacc., Trematosphaeria fissa (Fuckel) Winter and Trematosphaeria morthieri Fuckel, most of which are reported from the Czech and Slovak Republics for the first time. Species are listed with localities, descriptions, illustrations and taxonomical and ecological notes. Most of them occur rarely in both countries or have very interesting habitats. Capronia borealis and Capronia chlorospora, so far known only from the temperate zone of North America, are reported from Europe for the first time. The systematic position of these species is arranged according to Eriksson and Hawksworth (1993).

HUBÁLEK Z. (1981): A systematic survey of dimorphic and polymorphic fungi. Česká Mykologie 35(4): 209-226 (published: 1981)
abstract
Various definitions of the term dimorphism in fungi are briefly discussed and a general concept is given with a suggested morphological classification of the dimorphism. Dimorphism (and polymorphism) is delimited as an environmentally controlled reversible phenotypic duality (or plurality in the case of polymorphism) in the morphogenesis of the vegetative fungal cells, which is not restricted to pathogenic species and to the mycelial-yeast transitions only. A systematic list and an alphabetical index of the fungi exhibiting the phenomena of cellular dimorphism or polymorphism are presented.

abstract
This contribution presents further records of lichenicolous fungi previously unknown from Czechoslovakia. A new species, Polycoccum crassum sp. nov., parasitizing Peltigera lepidophora, is described. Two taxonomic recombinations are proposed: Opegrapha parasitica (Massal.) comb. nov. and Stigmidium eucline (Nyl.) comb. nov. All taxa are briefly described and illustrated, with taxonomic notes.
