Rozšíření a ekologie vatičkovitých hub v jižních Čechách
JIRSA, Aleš
Tomentelloid fungi, which include the genera Tomentella, Odontia, Polyozellus, Pseudotomentella, Tomentellopsis, and Amaurodon, represent a mainly ectomycorrhizal group from the order Thelephorales (Basidiomycota). They are common in forest ecosystems, however, they form inconspicuous fruitbodies that are mostly hidden under a layer of organic material. For this reason, the distribution and ecological traits of each species are poorly known. This thesis contains a list of tomentelloid species which have been recorded in South Bohemia and a description of their morphological features. Based on data from field sampling and herbarium collections, the distribution of each taxon has been described in the studied area and potential preferences for ectomycorrhizal host trees and habitat have been evaluated. This thesis brings forward the first data on the abundance or rarity of tomentelloid species and their ecology in South Bohemia and will be used for the preparation of a fungal checklist.

Mycobiota of energy sorrel
Janďourková, Hana ; Novotný, David (advisor) ; Mazáková, Jana (referee)
Energy sorrel (Rumex patientia L. x Rumex tianschanicus A. Los.) is a plant with a high yield of above-ground biomass. Because of this, it is grown as energy crop, but in Ukraine it is also important forage crop. Mycobiota has not been examined, even though energy sorrel is grown in the Czech Republic experimentally since 1992 (in agricultural operations since 2001). The aims of this thesis were: to determine the composition of mycobiota of healthy plants and of mycobiota associated with leaf and stem spots, to verify whether fungi isolated from spots can cause these spots and if previously isolated fungus Phomopsis sp. can cause spots. Samples were colected from 4 sites in Czech republic, in three samplings during the vegetation season. Endophytes were isolated from root, stem and leaf. Fungi asociated with spots were isolated from stem and leaf. Fungi were cultivated on 2% malt extract agar and then morphologically determined. From representative strains were isolated DNA and sequences of the ITS region were compared with the GenBank databases, this verified the morphological determination and the sterile species were determined. The most common endophytes were Clonostachys rosea f. rosea, Cladosporium cladosporioides, Rhizopus arrhizus var. arrhizus, Alternaria alternata a Acremonium strictum...

Houby revitalizovaného rašeliniště Soumarský Most
MATYSKOVÁ, Pavlína
This thesis is concerned with monitoring of fungal fruiting bodies and environmental factors influencing their occurrence (vegetation, pH, conductivity, water level and peat level) on 11 permanent areas, in three main vegetation types (Pine mire forests with Vaccinium, succession stage with high level of ground water and succession stage with low level of ground water) on the revitalized peat bog Soumarský Most. The total number of 104 fungal species were recorded, of which 79 belong to Basidiomycota (areas 9x9 m) and 35 belong to Ascomycota (inner areas 3x3 m). The highest Ascomycota species richness was found in succession stage with a high level of groundwater, whereas the highest Basidiomycota species richness was found in succession stage with a low level of groundwater. The occurrence of Ascomycota fruiting bodies was influenced by water level while the occurence of Basidiomycota fruiting bodies by the thickness of peat and the occurrence of Pinus rotundata.

Fungi were cultivated on 2% malt extract agar and then morphologically determined. From representative strains were isolated DNA and sequences of the ITS region were compared with the GenBank databases, this verified the morphological determination and the sterile species were determined. In total 24 morphotypes of endophytic fungi were cultivated from healthy plants. The most common species were: Clonostachys rosea f. rosea, Cladosporium cladosporioides, Rhizopus arrhizus var. arrhizus, Alternaria alternata and Acremonium strictum. From the spots were isolated in total 29 morphotypes, the dominant species were: A. strictum, Aureobasidium pullulans, C....
