Podyjí National Park is one of the hotspots of fungal diversity in the Czech Republic (so far we know about 1400 species from this area). The main reasons for this fact (well-preserved natural habitats, habitat and geological diversity) are introduced and briefly discussed in the article. high fungal diversity is documented based on several examples of rare or endangered species, which are typical for some of the local habitats and characterize the range of ecological conditions in the studied area. and Jan Běťák.
Ačkoli bylo světélkování u hub doloženo již ve starověku, intenzivnějšího vědeckého studia se tomuto jevu dostává teprve v posledních letech. Článek shrnuje naše dosavadní poznání bioluminiscence u hub z hlediska evolučního, ekologického i fyziologického. Jeho součástí jsou i fotografie dvou tropických druhů se světélkujícími plodnicemi - Mycena chlorophos a Filoboletus manipularis., Bioluminescence in fungi was first observed in the Archaic period or earlier, but it has only recently been studied scientifically. This paper sums up our knowledge on this phenomenon from evolutionary, ecological, and physiological points of view. Included are photos of two tropical species with luminescent fruiting bodies - Mycena chlorophos and Filoboletus manipularis., and Michal Sochor, Zuzana Egertová.
Plant virology department of the Institute of Plant Molecular Biology, Biology Centre of the Czech Academy of Sciences, is successful in description and sequencing of mycoviruses and plant viruses, recently. Most of the newly described viruses have unique genome organization and did not induce disease symptoms in their plant of fungal hosts, respectively. By contrast, some mycoviruses debilitate their hosts and are promising as tools for biological control of harmful fungi. and Karel Petrzik, Ondřej Lenz.
Filamentous microscopic fungi (moulds, predominantly from the phylum Ascomycota), a very diverse and versatile group of organisms, are able to colonize any kind of substrate. This article presents a short survey of some microfungi inhabiting our households. Examples are given of toxigenic fungi, xerophiles, psychrophiles, necrotrophs and sugar fungi. and Alena Kubátová.
Analyzovali jsme stanoviště a rozšíření houby šupinovky Henningsovy (Pholiota henningsii) v Evropě, kde je známa z Holandska, Akvitánie, Pařížské pánve, Massiv Central, úpatí Pyrenejí a Alp ve Francii a Švýcarsku, třetihorních pánví v Rakousku a jižních Čechách, z Mazurských jezer v Polsku, ostrova Sjaelland v Dánsku a ostrovů poblíž Stockholmu ve Švédsku. Všude je velmi vzácná a v mnoha zemích je zařazena na červených seznamech ohrožených druhů hub. Roste na slatinách, přechodových rašeliništích i vrchovištích, jak živinami bohatých, tak chudých. Váže se na lokality a oblasti s dlouhodobou (tisíciletou) historií otevřených rašelinišť ležících v blízkosti vodních nádrží. V ČR byly tři historické lokality doplněny v roce 2012 o dvě nové. Dlouhodobá mozaika lesa a bezlesí se zdá být hlavní podmínkou pro přežívání tohoto druhu reliktních stanovišť., The occurrence of the rare fungus Pholiota henningsii has been analysed in Europe. It is known from the Netherlands, the Parisian and Aquitanian basins, the Massif Central, and the foothils of the Pyrenées and Alps in France, Switzerland and Austrian Terciary basins, with numerous mires, in southern Bohemia, the Mazury lakes in Poland, Sjaelland island in Denmark and the island region near Stockholm in Sweden. In many countries it is included in Red Lists of endangered species. The fungus occurs in spring fens, transitional mires and raised bogs, both nutrient rich and oligotrophic. It is confined to localities with long term (i.e. millennia-long) mire non-forest continuity, in the vicinity of open water bodies up to the present. In the Czech Republic three historical sites were completed by two new localities in 2012. A temperate and forest - treeless mire mosaic seems to be the conditional factor for the long-term persistence of this relict species., and Jan Holec, Tomáš Kučera.
