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.
NOVOTNÝ D., JANKOVSKÝ L. (2005): Notes on mycobiota associated with Ips typographus from the Šumava Mts. (Czech Republic). [Piceaabies, ophiostomatoidfungi, bark beetles] Czech Mycology 57(1-2): 91-96 (published: 31st August, 2005)
abstract
In 1999 and 2000, stem samples of Norway spruce (Picea abies) infested by bark beetle (Ips typographus) from one spruce stand localitya ffected by massive infestation by Ips typographus in the central part of the Šumava mountains were taken.The mycobiota of 20 adults was studied. Eighteen species of microscopic fungi were recorded. Yeasts and ophiostomatoid fungi were detected most frequently.
JANKOVSKÝ L., HALTOFOVÁ P., JUHÁSOVÁ G., KOBZA M., ADAMČÍKOVÁ K., PALOVČÍKOVÁ D. (2004): The first record of Cryphonectria parasitica in the Czech Republic. [Castanea sativa, chestnut blight, Czech Republic, Cryphonectria parasitica, quarantine pest] Czech Mycology 56(1-2): 45-51 (published: 12th August, 2004)
abstract
The causal agent of chestnut blight Cryphonectria parasitica (Murrill) M. E. Barr is a quarantine pest that has been recorded for the first time on the territory of the Czech Republic. Cryphonectria parasitica was observed in a sweet chestnut in the town of Uherský Brod. Infected tree was imported as a two-year-old seedling from Bratislava (Slovakia), 25 years ago. The isolate of Cryphonectria parasitica has been compatible with European vc type 13 (EU 13). Castanea sativa Mill, occurs in more than 293 localities in the Czech Republic. Its state of health was checked in 232 localities.
JANKOVSKÝ L. (2003): Distribution and ecology of Armillaria species in some habitats of southern Moravia, Czech Republic. [Armillaria, root rots, hosts, ecology] Czech Mycology 55(3-4): 173-186 (published: 22nd December, 2003)
abstract
In forest ecosystems of southern Moravia, five species of annulate Armillaria species and the exannulate species Armillaria socialis were observed. Armillaria ostoyae shows its ecological optimum in the forest type group Querceto-Fagetum where it represents an important parasite of spruce. Armillaria gallica is a dominant species of floodplain forests and thermophilic oak communities where A. ostoyae is lacking. Armillaria mellea occurs on broadleaved species and fruit trees. Armillaria cepistipes and A. borealis were detected in the Drahanská vrchovina Highlands only, A. socialis occurs rarely on stumps and bases of dead oak trees in a hard-wooded floodplain forest along the Dyje river. It is one of the northernmost localities in Europe. Armillaria spp. were identified in 79 hosts, 33 of which were coniferous species. The main role of Armillaria spp. consists in the decomposition of wood in soil (stumps, roots) and in the species spectrum regulation in the course of succession.
