abstract
The summer truffle, Tuber aestivum, is the most common European truffle species with environmental and economic values yet unexplored in the Czech Republic. Background information on general features of this protected hypogeous ascomycete, its history and finds in our country as well as trends in T. aestivum cultivation and research in central Europe are summarized.
GRYNDLER M., BOROVIČKA J., GRYNDLEROVÁ H., GRYNDLER E. (2008): Fructification of Langermannia gigantea in artificially inoculated field soil. [Lycoperdaceae, Langermannia gigantea, Calvatia gigantea, spawn, cultivation, rDNA] Czech Mycology 60(2): 231-242 (published: 27th February, 2009)
abstract
Cultures of Langermannia gigantea, a fungus potentially important for human alimentation and biotechnology purposes, were isolated from wild-growing specimens and a spawn was produced using autoclaved soil as a cultivation substrate. The spawn of two isolates was placed into the soil in two field experimental plots. Fructification was first observed after 4 years in only one plot, where 3 normal fruitbodies were produced. Analysis of the rDNA cassette of the 3 fruitbodies revealed that they were identical and bore the attributes of both introduced isolates. The fungus is able to persist in the inoculated soil for years and is dispersed over the soil volume. This is the first report of successful fructification of L. gigantea introduced at a locality where this species had never been observed before.

(2007): The ascomycete Meliniomyces variabilis isolated from a sporocarp of Hydnotrya tulasnei (Pezizales) intracellularly colonises roots of ecto- and ericoid mycorrhizal host plants.

abstract
Attempts to isolate the ascomycete Hydnotrya tulasnei from fresh hypogeous sporocarps into a pure culture yielded beside H. tulasnei also a strain of Meliniomyces variabilis (MVA-2). Both phenotype and genotype analyses showed that MVA-2 was highly similar to another M. variabilis strain, isolated previously from a root tip of Picea abies. The mycorrhizal potential of both H. tulasnei and M.variabilis is still dubious. Therefore, we tried an in vitro synthesis of root-fungus association between H. tulasnei, both M. variabilis strains and typically ectomycorrhizal (P. abies and Pinus sylvestris) and typically ericoid mycorrhizal (Vaccinium corymbosum) host plants. For comparison, a strain of Rhizoscyphus ericae was included. Both M. variabilis strains formed intracellular structures characteristic of ericoid mycorrhiza in V. corymbosum roots, and also colonised the roots of P. abies and P.sylvestris seedlings, modifying their morphology. Superficially, Picea and Pinus root tips resembled early stages of EcM development, but transversal sections revealed absence of the Hartig net and frequent intracellular colonisation of the cortex. The reference strain of R. ericae showed similar behaviour in Picea, Pinus and Vaccinium roots, only the intracellular colonisation was more intensive and morphology of roots of both conifers was less changed when compared to M. variabilis. H. tulasnei failed to colonise the roots of P. abies and V. corymbosum, possibly due to sub-optimal conditions for its growth.
