ĎURIŠKA O., ANTONÍN V., PARA R., TOMŠOVSKÝ M., JANČOVIČOVÁ S. (2017): Taxonomy, ecology and distribution of Melanoleuca strictipes (Basidiomycota, Agaricales) in Europe. [taxonomy, phylogeny, M. subalpina, M. substrictipes var. sarcophyllum] Czech Mycology 69(1): 15-30 (published: 9th May, 2017)
abstract
Melanoleuca strictipes (P. Karst.) Métrod, a species characterised by whitish colours and macrocystidia in the hymenium, has for years been identified as several different species. Based on morphological studies of 61 specimens from eight countries and a phylogenetic analysis of ITS sequences, including type material of M. subalpina and M. substrictipes var. sarcophyllum, we confirm conspecificity of these specimens and their identity as M. strictipes. The lectotype of this species is designated here. The morphological and ecological characteristics of this species are presented.
KAUTMANOVÁ I., MATOUŠ J., TOMŠOVSKÝ M., KOUKOL O. (2016): Redescription and epitypification of Clavaria atrofusca Velen. [Clavariaceae, taxonomy, LSU rDNA] Czech Mycology 68(1): 67-77 (published: 13th April, 2016)
abstract
Clavaria atrofusca was described by Velenovský in 1939 based on a single small collection from the Czech Republic. The species is rather rare and until 2009 it had further only been recorded from Switzerland and Denmark. Since 2009 it has also been collected in Norway, Sweden and in 2014 in the Czech Republic. Because the type locality at Mnichovice has been destroyed and the type collection is fragmentary, we propose an epitype of Clavaria atrofusca Velen. based on the recent collection from the Czech Republic, along with the notes on its ecology and distribution.
ANTONÍN V., TESTONI A., TOMŠOVSKÝ M. (2015): Crinipellis mezzanensis, a new species from Italy. [Marasmiaceae, Basidiomycota, ITS, Mezzano valley] Czech Mycology 67(1): 23-27 (published: 10th April, 2015)
abstract
Crinipellis mezzanensis is described from Mezzano Valley, Ferrara Prov., Italy. It is characterised in having moderately large basidiospores, well-developed simple cheilocystidia, absent pleurocystidia, and green-blue coloured plaques of pileipellis hyphae in KOH.
DVOŘÁK D., BĚŤÁK J., TOMŠOVSKÝ M. (2014): Aurantiporus alborubescens (Basidiomycota, Polyporales) - first record in the Carpathians and notes on its systematic position. [Aurantiporus, phylogeny, old-growth forests, beech forests, indicator species] Czech Mycology 66(1): 71-84 (published: 4th June, 2014)
abstract
The authors present the first collection of the rare old-growth forest polypore Aurantiporus alborubescens in the Carpathians, supported by a description of macro- and microscopic features. Its European distribution and ecological demands are discussed. LSU rDNA sequences of the collected material were also analysed and compared with those of A. fissilis and A. croceus as well as some other polyporoid and corticioid species, in order to resolve the phylogenetic placement of the studied species. Based on the results of the molecular analysis, the homogeneity of the genus Aurantiporus Murrill in the sense of Jahn is questioned.
ANTONÍN V., KRAMOLIŠ J., TOMŠOVSKÝ M. (2012): Two collections of albinotic forms of Tubaria (Basidiomycota, Agaricales, Inocybaceae). [Tubaria hiemalis, Tubaria romagnesiana, Tubaria furfuracea, albinotic forms, taxonomy, ITS] Czech Mycology 64(2): 197-208 (published: 7th December, 2012)
abstract
The record of an albinotic Tubaria from the Czech Republic was studied and compared with a macroscopically similar collection from Norway. However, the two specimens represent different taxa due to both morphological characters and DNA sequences. The main microscopic characters usually used for species identification of the Tubaria furfuracea complex (including T. furfuracea, T. hiemalis, and T. romagnesiana) are discussed on the base of studied collections from the BRNM herbarium. According to our studies, the main characters (size of basidiospores, shape and size of cheilocystidia, width of the hymenophoral trama hyphae) usually used for identification of these three species are not generally applicable. Further detailed anatomic-morphological and molecular studies are desirable to solve the problem of species limits in the Tubaria furfuracea complex.
ČERNÝ K., GREGOROVÁ B., STRNADOVÁ V., TOMŠOVSKÝ M., HOLUB V., GABRIELOVÁ Š. (2008): Phytophthora cambivora causing ink disease of sweet chestnut recorded in the Czech Republic. [Phytophthora cambivora, ink disease, Castanea sativa, sweet chestnut, Czech Republic] Czech Mycology 60(2): 265-274 (published: 27th February, 2009)
abstract
Sweet chestnut (Castanea sativa) is a non-autochthonous but commonly planted ornamental tree in the Czech Republic. However, this species is sensitive to some Phytophthora infections causing socalled ink disease. The disease usually occurs in warmer regions in Europe. In the Czech Republic it had not been detected until the nineties of the 20th century. In 1997 extensive decline of a sweet chestnut ornamental orchard with typical symptoms of ink disease was found at one locality in eastern Bohemia. Later the causal organism of this disease Phytophthora cambivora (Petri) Buisman was isolated from necrotised tissues of trunks of several declining chestnut trees. This is the first find of the pathogen causing ink disease of chestnut in the Czech Republic.
TOMŠOVSKÝ M. (2008): Molecular phylogeny and taxonomic position of Trametes cervina and description of a new genus Trametopsis. [Trametopsis, Trametes, ribosomal DNA, polypore, taxonomy] Czech Mycology 60(1): 1-11 (published: 4th July, 2008)
abstract
Trametes cervina (Schwein.) Bres. differs from other species of the genus by remarkable morphological characters (shape of pores, hyphal system). Moreover, an earlier published comparison of the DNA sequences within the genus revealed considerable differences between this species and the remaining European members of the genus Trametes. These results were now confirmed using sequences of nuclear LSU and mitochondrial SSU regions of ribosomal DNA. The most related species of Trametes cervina are Ceriporiopsis aneirina and C. resinascens. According to these facts, the new genus Trametopsis Tomšovský is described and the new combination Trametopsis cervina (Schwein.) Tomšovský is proposed.
TOMŠOVSKÝ M., JANKOVSKÝ L. (2007): DNA sequence analysis of extraordinary fruiting specimens of Fuscoporia torulosa (Phellinus torulosus) on Pyrus spp. [Fuscoporia, Phellinus, DNA, ITS region, fructification] Czech Mycology 59(1): 91-99 (published: 28th June, 2007)
abstract
Fuscoporia torulosa (Phellinus torulosus) is a typical polypore of thermophilous forests in Central Europe. In most cases the fungus forms basidiocarps on base or roots of various host trees (mainly Quercus), but sometimes the basidiocarps appear on stem heights of approx. 2 m. This extraordinary fructification pattern seems to be restricted to Pyrus as a host. The aim of this study was to compare such basidiocarps with those growing on the base of oak trees according to their DNA sequences to reveal a possible process of speciation. The so-called ITS region of nuclear ribosomal DNA was chosen for the study. Results did not reveal any significant differences between basidiocarps with the distinct fructification pattern, so all examined specimens belong to one species. The relation of Fuscoporia torulosa to Phellinus senex is discussed.
ANTONÍN V., JANKOVSKÝ L., LOCHMAN J., TOMŠOVSKÝ M. (2006): Armillaria socialis - morphological-anatomical and ecological characteristics, pathology, distribution in the Czech Republic and Europe and remarks on its genetic variation. [Armillaria, Desarmillaria, description, distribution, pathology, ecology, ITS sequences, genetic variation] Czech Mycology 58(3-4): 209-224 (published: 29th December, 2006)
abstract
Armillaria socialis belongs to subgen. Desarmillaria. Its correct specific name (in comparison with the frequently used name A. tabescens) is discussed, and its detailed macro– and microscopic description and distribution in the Czech Republic and Europe are given. It is a thermophilic species occurring in Europe, USA, Japan and China. The northern distributional limit in Europe runs through Central Europe. In the Czech Republic, A. socialis occurs in thermophilic oak stands and also in alluvial forests. It was found on oaks, field maple and ash. A molecular study using sequence data from ribosomal DNA (ITS region) revealed a relatively high intraspecific genetic variation among sequences of A. socialis from various localities of the Czech Republic and France. The results resemble those published earlier from the USA.
TOMŠOVSKÝ M., HOMOLKA L. (2003): Pigment production in incompatibility zones of Trametes versicolor is in correlation with the laccase activity of the dikaryons involved. [Basidiomycetes, Trametes versicolor, laccase, pigment, test] Czech Mycology 55(3-4): 155-160 (published: 22nd December, 2003)
abstract
A correlation between the extracellular laccase activity (estimated by a drop test using ABTS) and the presence of a dark pigmented zone in the pairing of different Trametes (Coriolus) versicolor dikaryons in vitro was studied. Al together 24 dikaryotic strains from different substrates and distant localities of three European countries were paired to each other and the pairings were checked for the presence of dark pigment in the contact zone. Using the \2 test, a positive correlation between the laccase activity and the presence of pigment was found.
TOMŠOVSKÝ M. (2002): The genus Phellinus in the Šumava Mts. [Basidiomycetes, Hymenochaetaceae, Phellinus, Šumava Mts. (Czech Republic), ecology, distribution] Czech Mycology 54(1-2): 45-78 (published: 3rd October, 2002)
abstract
The ecology and distribution of species of Phellinus (Basidiomycetes, Hymenochaetaceae) in the Šumava Mts. was studied. The study area represents the Czech part of the Šumava mountain range at the border of the Czech Republic, Germany and Austria. The area was intensively studied during they ears 1997-2000. The data based on the author’s own records were complemented with unpublished records based on collections deposited in the PRM herbarium. Al together 18 species of Phellinus were confirmed for the Šumava Mts. The distribution, altitude range, substrate specificity and vegetation preference of each species are evaluated. The text is completed with distribution maps of the species.
TOMŠOVSKÝ M. (2001): Remarks on the distribution of Hymenochaete carpatica in Central and Eastern Europe. [Hymenochaete carpatica, ecology, distribution, Europe] Czech Mycology 53(2): 141-148 (published: 20th February, 2002)
abstract
Hymenochaete carpatica Pilát is an inconspicuous species that was almost completely overlooked until 1988 (Baici and Léger 1988) since its description in 1930. The ecology and distribution of the species in Central and Eastern Europe is described. Hymenochaete carpatica grows only on bark chips of old living trunks of Acerpseudoplatanus and has not been found on any other host. This species is known from Austria, the Czech Republic, France, Germany and Slovakia. Recently it was also found in Romania and the Ukraine for the first time. Two maps demonstrate the distribution of Hymenochaete carpatica in the Czech Republic and Europe to date.
