KOUKOL O., HALASŮ V., JANOŠÍK L., MLČOCH P., POLHORSKÝ A., ŠANDOVÁ M., ZÍBAROVÁ L. (2020): Citizen science facilitates phylogenetic placement of old species of non-lichenised Pezizomycotina based on newly collected material.

abstract
During the informal Spring Micromyco 2019 meeting, we tested how newly obtained molecular barcodes of common or poorly known saprotrophic microfungi from more or less targeted collections may be useful for identification and taxonomic studies. Our aim was to obtain DNA sequences of fungi enabling their phylogenetic placement and routine identification in the future using molecular barcoding. As a result, DNA of four species was sequenced for the first time, among them Leptosphaeria acuta, for which a new synonym L. urticae is proposed. The new combination Koorchaloma melaloma is proposed for a species previously known as Volutella melaloma and its new synonym is K. europaea. This species is accommodated in the Stachybotryaceae. A detailed phenotypic description and phylogenetic placement are provided for Mytilinidion insulare, a resurrected species hitherto considered a later synonym of M. gemmigenum. Chalara insignis was placed in the Helotiales without any clear relationship to other members of this order. For another two helotialean species, a second referencing sequence was obtained. Our study showed that for some microfungi, due to the fundamental lack of molecular data, even a single molecular barcode may provide novel and important information on their phylogenetic and taxonomic placement. The results also illustrate that scientific progress can be made through collaboration between academic and amateur mycologists.
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.
NOVÁKOVÁ A., PIŽL V. (2003): Mycoflora in the intestine of Eisenia andrei (Oligochaeta, Lumbricidae) and in vermiculture substrates. [cattle manure, saprotrophic and cellulolytic microfungi, earthworms] Czech Mycology 55(1-2): 83-102 (published: 23rd July, 2003)
abstract
Mycoflora of three commercial vermiculture systems based on cattle manure derived sub strates and Eisenia andrei earthworms was studied using several isolation methods. A total of 172 taxa of saprotrophic micromycetes were isolated (19 taxa of Zygomycetes, 9 taxa of Ascomycetes and 144 taxa of mitosporic fungi). Aspergillus fumigatus was the most frequent microfungal species in the intestine of Eisenia andrei. In vermicuture substrates, Aspergillus flavus and Aspergillus fumigatus were among species isolated very frequently by the soil dilution method, while Rhizopus stolonifer was estimated as frequent species using the soil washing isolation technique.
NOVÁKOVÁ-ŘEPOVÁ A. (1992): The growth of soil micromycetes in the media containing herbicides Basagran, Labuctril 25 and Oxytril CM. Česká Mykologie 46(1-2): 86-92 (published: 1st April, 1993)
abstract
The changes of fungal growth in laboratory experiments (estimation of mycelial biomass and colony diameter) were studied by cultivation of 10 species of soil fungi on media with different concentrations of the herbicides Basagran, Labuctril 25 and Oxytril CM. The subject fungi responded to increased concentrations of herbicide in different ways. Cladosporium herbarum (colony diameter) and Penicillium janthinellum (mycelial biomass) were the only investigations to show a similar response to all the herbicides. Penicillium janthinellum (mycelial biomass) was the only example of a significant stimulation of fungal growth. Changes in colony pigmentation and sporulation were also recorded.
