KOCOURKOVÁ-HORÁKOVÁ J. (1998): Records of new, rare or overlooked lichens from the Czech Republic. [Czech Republic, Křivoklátsko, lichens and lichenicolous fungi, distribution, rare species] Czech Mycology 50(3): 223-239 (published: 16th May, 1998)
abstract
Alist of 26 species of lichens and 2 lichenicolous fungi from the CzechRepublic with comments isgiven. 11speciesarenew for the country: the lichensAbsconditelladelutula, Aspiciliamoenium, Bacidina chloroticula, Epigloea medioincrassata, Lecanora pseudistera, Micarea botryoides, Phaeocalicium compressulum, Trapeliopsis pseudogranulosa, Xanthoria calcicola and the lichen icolous fungiEndococcus pseudocarpus and Zwackhiomyces sphinctrinoides; 4 lichens are new for Bohemia (Agonimia tristicula, Bacidina amoldiana, Buellia epigaea, Endocarpon psorodeum) and 1 for Moravia (Absconditella lignicola). Belonia incamata is new for the Šumava Mts. Diploicia canescens, Parmelia glabra and Parmelia revoluta, species which had been missing in the Czech Republic for a long period of time, were recently rediscovered. Other included lichens are very rarely found and are known from only a few localities in the Czech Republic. A large number of recordsare from the Protected Landscape Area Křivoklátsko, in the Rakovník District.
MOSER-ROHRHOFER M. (1965): Der Anteil des Pilzes und der Alge am Aufbau der Gallerte von Collema. Česká Mykologie 19(4): 205-211- (published: 1965)
abstract
The study investigates the contribution of fungus and alga to the gelatinous matrix in Collema lichens. The gelatinous material contains chitin, not cellulose. The slime produced by fungal hyphae is anisotropic, whereas algal slime is isotropic within the thallus. The work concludes that the fungus predominantly produces the gelatinous matrix, shaping the lichen’s morphology, with the alga playing a limited role.
