New and Interesting Records of Cladonia and their Lichenicolous Fungi from the Andean Cloud Forest in Bolivia

The paper deals with 18 species of the lichen genus Cladonia, including eight species new to Bolivia: C. cf. borbonica, C. coccifera, C. confragosa, C. dactylota, C. granulosa, C. kriegeri, C. merochlorophaea, and C. squamosa. Furthermore, C. kriegeri is recorded here from its second and third localities in the world. Also five lichenicolous fungi are reported; among them Arthrorhaphis aeruginosa, Polycoccum microcarpum and Sphaerellothecium cladoniae are new to the southern hemisphere, and Roselliniella cladoniae and Tremella cladoniae are new to Bolivia. Additionally, Polycoccum microcarpum is reported for the first time from Slovakia and Ukraine. Cladonia confragosa is reported as a new host for Sphaerellothecium cladoniae and Tremella cladoniae.

New or noteworthy records of Caloplaca ( Teloschistaceae ) from Poland

Caloplaca atroalba, C. dichroa, C. marmorata, C. oasis, and C. pseudofulgensia are reported as new to Poland. Two other taxa: C. albopruinosa and C. pusilla are discussed in view of modern approaches. The species reported here were mainly collected in the Polish Carpathians. Additionally, C. atroalba is reported as new to Ukraine. Detailed taxonomic descriptions and comments are provided for the treated taxa.

Three New, Seemingly-Cryptic Species in the Lichen Genus Caloplaca (Teloschistaceae) Distinguished in Two-Phase Phenotype Evaluation

We describe three new, seemingly-cryptic species in the lichen genus Caloplaca (Teloschistaceae) with black apothecia. Those species, separated in nrITS and β-tubulin DNA phylogenies, appeared to be phenotypically indistinguishable. We looked for their phenotypic differences using a two-phase method comprised of a preliminary examination in which diagnostic value of all available characters was evaluated using a small number of samples and potentially-diagnostic characters were selected, and a subsequent detailed study in which characters selected in the first phase were tested using more samples. We found 19 diagnostic characters (continuous and discrete) of which four continuous and three discrete characters could be considered “fully diagnostic”, i.e. allowing for correct identification of at least one species. Hence, the three species are not cryptic, but can be distinguished phenotypically. Here, they are formally described as Caloplaca micromarina Frolov, Khodos. & Vondrák sp. nova, C. micromontana Frolov, Wilk & Vondrák sp. nova and C. microstepposa Frolov, Nadyeina, Khodos. & Vondrák sp. nova.
