Investigation of the Armillaria cepistipes - A. gallica complex in the Czech Republic

Original language description

Armillaria cepistipes and A. gallica (Basidiomycota, Marasmiaceae) are macro- and micromorphologically very close species. In many cases, there are (almost) indistinguishable. Ecologically, A. gallica seems to prefer warmer areas in lowlands (oak and alluvial forests) while A. cepistipes is more common in hilly and lower montane beech forests. However, several localities with the presence of both species are known. The PCR-RFLP method based on ITS region of rDNA was applied for the identification of these species. Each of the species is characterised by the specific RFLP profile. On the contrary, some specimens with an intermediate profile were detected. The sequenation of the translation elongation factor 1-alpha showed higher interspecific variability and this gene seems to be more suitable to distinguish Armillaria gallica and A. cepistipes than ITS region. To reveal a possible interspecific hybridization between the two species, AFLP fingerprinting method was applied.

Průzkum komplexu druhů Armillaria cepistipes - A. gallica v české republice

Czech description

Armillaria cepistipes a A. gallica (Basidiomycota, Marasmiaceae) jsou morfologicky velice podobné druhy václavek, které jsou morfologicky téměř nerozpoznatelné. Z ekologického hlediska A. gallica preferuje teplejší oblasti v nížinách (doubravy, lužní lesy), zatímco A. cepistipes je hojnější v bučinách. Na druhou stranu je známo několik lokalit, na kterých se oba druhy vyskytují sympatricky. Metody PCR-RFLP založená na DNA sekvenci tzv. ITS oblasti ribozomální DNA a DNA sekvence genu pro translační elongační faktor 1-alfa byly použity pro rozlišení obou druhů.
