GRISHKAN I., TEMINA M. (2023): Diversity of microfungal communities inside saxicolous lichens from Nahal Oren, Mount Carmel, Israel. [endolichenic fungi, lichen thallus, melanised fungi, microclimatic contrast, rock surface.] Czech Mycology 75(1): 15-34 (published: 28th March, 2023) Electronic supplement
abstract
In this study, we examined the endolichenic fungal communities of saxicolous lichens covering the rocks in the Nahal Oren valley, northern Israel. A total of 60 fungal species belonging to 35 genera were isolated from six lichen species collected in the summer and winter on the south-facing slope (SFS) and north-facing slope (NFS) of the valley. We verified that rocks serve as a possible source for the formation of endolichenic communities because communities colonising lichen thalli and the rock surface shared 39% of species and clustered together on the SFS. On the NFS, with a comparatively favourable microclimate, lichen thalli abundantly harboured typical soil fungi such as Clonostachys rosea and Fusarium spp. in winter and summer, respectively. At the same time, more severe environmental conditions on the SFS facilitated the prevalence of melanised fungi with thick-walled and multicellular spores irrespective of season. The lowest species richness and isolate densities of endolichenic communities were registered in the thalli of Collema cristatum. This decrease, especially expressed in the summer, was probably associated with the antifungal effect of substances produced by its cyanobiont, as well as with the heavy dehydration of thalli during the dry season.
KOUKOL O., MAGDALINOU E., PÁNKOVÁ H., BOROVIČKA J., MÜNZBERGOVÁ Z. (2022): Do microclimatic conditions in two forest types on serpentine bedrock affect culturable microfungi in pine litter needles? [fungal diversity, ITS rDNA, temperature and humidity, Pinus sylvestris.] Czech Mycology 74(2): 181-194 (published: 24th November, 2022)
abstract
Microfungi colonising coniferous needles in litter were intensively studied in previous decades, but forest stands on serpentine soils have been overlooked. Also, the effects of microclimatic conditions on fungal communities in coniferous litter are unknown. In our study, we aimed to characterise communities of culturable microfungi colonising pine litter needles collected from two types of Scots pine forest growing on serpentine bedrock, i.e. dense forest with relatively stable microclimatic conditions and open-canopy forest on exposed rock with highly variable conditions. The composition of their fungal communities was analysed in respect to microclimatic conditions at the collection sites. Using a combination of phenotypic and molecular data (sequences of ITS rDNA), 35 taxa were distinguished in 1078 fungal colonies recorded, out of which 25 were identified to the species level. Fungal communities were most affected by needle type (litter vs. fermentation layer) followed by maximum temperature during the previous five months. Interestingly, a higher number and abundance of species were recorded at the warmer site, in the open-canopy forest. Dominant fungi recorded in this study (Desmazierella acicola, Phacidium lacerum and Scleroconidioma sphagnicola) were mostly identical to those recorded in previous studies and the occurrence of less abundant taxa previously not recorded in pine litter suggests that the uppermost litter layer represents an important reservoir of fungal diversity.
ABDEL-SATER M.A., MOUBASHER A.H., SOLIMAN Z.S.M. (2016): Diversity of filamentous and yeast fungi in soil of citrus and grapevine plantations in the Assiut region, Egypt. [Mycobiota, biodiversity, phenotypic and biochemical characterisation, ITS sequence, Coniochaeta canina, Aspergillus stella-maris] Czech Mycology 68(2): 183-214 (published: 20th December, 2016)
abstract
An extensive survey of soil mycobiota on citrus and grapevine plantations in Sahel-Saleem City, Assiut Governorate, Egypt was carried out using the dilution-plate method and 2 isolation media at 25 °C. Sixty-four genera and 195 species of filamentous fungi and 10 genera and 13 species of yeasts were recovered. A higher diversity (number of genera and species) and gross total counts were recovered from citrus than from grapevine soil. The peak of filamentous fungi recovered from both soils was found to be in February. Aspergillus (45 species) was the most dominant genus; A. ochraceus predominated in citrus plantations, while A. niger and A. aculeatus in grapevine. The Penicillium count came second after Aspergillus in citrus (23 species) and after Aspergillus and Fusarium in grapevine (11 species).Penicillium citrinum, P. ochrochloron and P. olsonii were more common in citrus plantations, but they were replaced by P. oxalicum in grapevine soil. Fusarium (19 species) was represented in 88.9–100% of both soils on both media; F. solani predominated in both soils, while F. incarnatum came next in citrus, and F. babinda and F. oxysporum in grapevine. Humicola (3 species) with the dominant H. fuscoatra was recorded in 61.1–83.3% of soil of both plantations, while Talaromyces (with T. purpureogenus followed by T. pinophilus being the most common) was recorded in 83.3–100% on DRBC and 38.9–50% on DYM from the soil of plantations of both crops. Volutella (5 species) was common in citrus but missing from grapevine soil. The present study reveals that hyaline fungi predominated over dark-coloured ones. Yeasts comprised only minor proportions in both soils (maximum 0.5%). They showed their peak in the soil of citrus plantations in April and in grapevine in February. All species were recovered in one or two samples only. Diutina catenulata, Debaryomyces hansenii, Galactomyces (3 species), Hanseniaspora occidentalis, Kluyveromyces marxianus, Meyerozyma caribbica, and Schwanniomyces pseudopolymorphus were encountered in citrus only, while Cryptococcus laurentii, Pichia kudriavzevii, Meyerozyma guilliermondii and Rhodotorula sp. in grapevine only. Physiological and growth characteristics were obtained for most of the recovered yeasts.
ABDULLAH S.K., MONFORT E., ASENSIO L., SALINAS J., LOPEZ LLORCA L.V., JANSSON H.B. (2010): Soil mycobiota of date palm plantations in Elche, SE Spain. [soil saprotrophic fungi, phytopathogenic fungi, Phoenix dactylifera, isolation methods] Czech Mycology 61(2): 149-162 (published: 10th August, 2010)
abstract
The mycobiota of soil from date palm (Phoenix dactylifera) plantations in Elche, SE Spain was examined using 23 soil samples and five isolation methods. One hundred and nineteen species assigned to 67 genera were isolated. The most frequent species were in decreasing order: Aspergillus fumigatus, A. niger, Neosartorya spinosa, Thielaviopsis punctulata, Chaetomium bostrychodes, Gilmaniella macrospora, Aspergillus candidus, Fusarium oxysporum, Rhizopus microsporus, Sordaria fimicola, Aspergillus terreus, Chaetomium murorum, Fusarium solani, Mucor racemosus, Penicillium citrinum and Thielaviopsis paradoxa. The thermotolerant and thermophilic species of Malbranchea cinnamomea, Myriococcum thermophilum, Rhizomucor miehei, Scytalidium thermophilum, Talaromyces emersonii, Thermoascus aurantiacus and Thermomyces lanuginosus were detected in various frequencies of occurrence. Our findings are compared with those from a similar survey of soil from date palm plantations in Iraq. Our study indicates that there is no characteristic mycobiota for soil in date palm plantations except for the more frequent isolation of some species well known as pathogens on date palm.
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.
