SANTIAGO K.A.A., DELA CRUZ T.E.E., TING A.S.Y. (2021): Diversity and bioactivity of endolichenic fungi in Usnea lichens of the Philippines.   [antibacterial, anticandidal, antioxidant, lichen-associated, Sagada.]  Czech Mycology 73(1): 1-19   (published: 14th January, 2021)   Electronic supplement
  abstract   Endolichenic fungi (ELF; asymptomatic microorganisms living inside healthy lichen thalli) were isolated from three Usnea species, namely U. baileyi, U. bismolliuscula and U. pectinata, collected near the town of Sagada, Philippines. A total of 101 ELF were recovered representing 12 genera (classes Sordariomycetes and Eurotiomycetes), with the genera Nemania (50.5%, 51 isolates) and Xylaria (22.8%, 23 isolates) being the most abundant. Comparative analyses on the antimicrobial activities of lichens and ELF revealed that lichen crude extracts were effective against the Gram-positive bacterium Staphylococcus aureus and the yeast Candida albicans, while ELF crude extracts were effective against S. aureus, C. albicans and the Gram-negative bacterium Escherichia coli. The broad-spectrum nature of ELF has provided medicinal and industrial advantages over the slow-growing lichens as shown on their respective bioactivities. Extracts from ELF also had a higher total flavonoid content (TFC; 6.29–85.69 mg QE/g of extract) and stronger antioxidant activities (IC₅₀: 0.57–19.63 mg/ml) than lichen-derived extracts. Although only culturable ELF were identified, this study provides the first evaluation of the diversity and bioactivities of culturable ELF from fruticose lichens of the genus Usnea in the Philippines.

(2016): Fungi and lichens recorded during the Cryptogam Symposium on Natural Beech Forests, Slovakia 2011.   [old-growth beech forests, diversity, conservation, indicator, red-list, Europe]  Czech Mycology 68(1): 1-40   (published: 1st February, 2016)
  abstract   In September 2011, an international team of cryptogam experts visited seven national nature reserves in five mountain areas of Slovakia: Havešová and Stužica in the Poloniny Mts., Vihorlat in the Vihorlatské vrchy Mts., Oblík in the Slanské vrchy Mts., Dobročský prales and Klenovský Vepor in the Veporské vrchy Mts. and Badínsky prales in the Kremnické vrchy Mts. The reserves were selected to represent examples of the best protected old-growth beech forests in the country. The aim was to study the diversity of wood-inhabiting fungi on fallen beech logs and epiphytic lichens on standing beech trees. In total, 215 fungal species and 128 lichens were recorded on beech wood and bark, and 27 fungi and 26 lichens on additional substrates. The site of the highest conservation value is Stužica with 126 fungi and 79 lichens recorded on beech, of which 12 fungi and 19 lichens are indicators of high nature conservation value. Combined with historical records, a total of 19 non-lichenised fungal indicators are now reported from the site, making it the highest ranked natural beech forest in Europe. The second most important reserve for fungal diversity is Havešová with 121 species, including 14 indicator species recorded on beech wood. For lichens, the second most important reserve is Klenovský Vepor with 69 species including 18 lichen indicators recorded on beech. Nine fungus species are here reported as new to Slovakia: Asterostroma medium, Entoloma hispidulum, E. pseudoparasiticum, Gloeohypochnicium analogum, Hohenbuehelia valesiaca, Hymenochaete ulmicola, Hypocrea parmastoi, Melanomma spiniferum and Scutellinia colensoi. Lichen species Alyxoria ochrocheila is reported as new to Slovakia and Lecanographa amylacea, which was considered extinct in the Slovak Red list, was also recorded. This is the first list of wood-inhabiting fungi and epiphytic lichens of old-growth beech forests in Slovakia, and hence an important contribution to the exploration of biodiversity in Slovakia.

BALAJI P., HARIHARAN G.N. (2013): Checklist of microlichens in Bolampatti II Forest Range (Siruvani Hills), Western Ghats, Tamil Nadu, India.   [microlichen diversity, substratum, forest types, photobiont, conservation, Western Ghats]  Czech Mycology 65(2): 219-232   (published: 20th December, 2013)
  abstract   A checklist of 137 microlichen species is provided based on the identification of specimens collected from three different vegetation types within the Bolampatti II Forest range (Siruvani Hills), Western Ghats. The dominant family is Porinaceae with 23 species. The dominant genus is Porina with 21 species. The diversity (87) and number of specific species (31) are highest at the Moist Mixed Deciduous Forest (MMDF) type, while there are about 30 lichen species common to all three different forest types studied. A total of 58 lichen species are new to this area. Study on habitat preferences of the lichens showed that most lichens grow on bark (75 %), followed by rock and leaf substrata. Concerning photobiont distribution, most Trebouxia containing lichens were found in the Dry Mixed Deciduous Forest (DMDF), while Trentepohlia is most frequent in MMDF. The presented number and types of lichens, and their ecological preferences will be a basis for conducting their future conservation and biomonitoring studies in various habitats of India.

JANČOVIČOVÁ S., MIŠÍKOVÁ K., GUTTOVÁ A., BLANÁR D. (2011): The ecological knowledge on Crepidotus kubickae - a case study from central Slovakia.   [Inocybaceae, C. cesatii var. subsphaerosporus, Norway spruce forests, ecology, syntaxonomy]  Czech Mycology 63(2): 215-241   (published: 10th August, 2011)
  abstract   The ecological knowledge on Crepidotus kubickae is not only insufficient in Slovakia but also in the rest of Europe. In the years 2008–2011, a case study was therefore carried out in central Slovakia to find out more data on its habitats and substrate preferences. During the research, 30 collections were gathered at seven localities of the Veporské vrchy Mts., Stolické vrchy Mts. and Muránska planina Plateau.The substrates of the collections were precisely described and collecting sites characterised and documented by phytocoenological relevés. In the selected area, C. kubickae occurred in several types of spruce or mixed forests (with dominance of Picea abies); namely in six associations of forest communities: Vaccinio myrtilli-Piceetum, Athyrio alpestris-Piceetum, Calamagrostio variae-Abietetum, cf.Cortuso-Fagetum, cf. Poo chaixii-Fagetum, and Dentario enneaphylli-Fagetum. The altitude of most collecting sites was above 1100 m a. s. l. The species preferred dead corticated fallen and standing stems of Picea abies of approx. 15–100 cm in diameter, aged about 70–180 years. In this paper, also the ecological knowledge on C. kubickae in Europe is summarised.

KOCOURKOVÁ J. (1999): Lichenicolous fungi from the Czech Republic. 1. Weddellomyces xanthoparmeliae Calatayud et Nav.-Ros.   [Dothideales, Dacampiaceae, Weddellomyces xanthoparmeliae Calatayud et Nav.-Ros., lichenicolous fungi, taxonomy, Xanthoparmelia]  Czech Mycology 51(2-3): 179-184   (published: 25th May, 1999)
  abstract   The parasitic lichenicolous fungus Weddellomyces xanthoparmeliae Calatayud et Nav.-Ros., recently described from Xanthoparmelia cf. protomatra (Calatayud et Navarro-Rosinés 1998) is now reported also from central Europe from the Czech Republic. It has been collected in several localities on Xanthoparmelia conspersa (Ehrh. exAch.) Hale and X. somloensis (Gyelnik) Hale. Weddellomyces xanthoparmeliae occurs in great quantity in all the Czech and Moravian localities and therefore it seems possible to find it without difficulties also in other warm areas in situations with rather xerothermic habitats where the hosts are commonly present.

  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.
