Cladonia luteoalba a C. norvegica – nové dutohlávky pro ČR

Cladonia luteoalba Wils. et Wheld. and C. norvegica Tonsberg et Holien are reported for the first time from the Czech Republic. Chemical analysis (TLC) confirmed usnic and squamatic acid (C. luteoalba) and barbatic acid (C. norvegica). Both species seemed to be rather rare in Central Europe till now but might be only overlooked.
