| Malíček J. & Vondrák J. : Lišejníky chráněných území Ralsko a Vranovské skály (severní Čechy) , 1-23 [Lichens of the protected areas Ralsko and Vranovské skály (North Bohemia)] Abstract: [The diversity of lichenized fungi was explored in two close protected areas, Ralsko and Vranovské skály, during several field excursions in 2017 and 2018. We present a list of 298 species, including 272 recently recorded taxa: 223 species from Ralsko and 137 species from Vranovské skály. The Ralsko Nature Reserve protects ecosystems of tephrite rocks and boulder screes, a castle ruin and old-growth scree woodlands. Rare species are mostly represented by montane epilithic lichens, for example Acarospora insolata, Melanelia panniformis, Fuscidea recensa, Lecanactis dilleniana, Lecanora cenisia f. soredians, Ophioparma ventosa, Porpidia cinereoatra, Stereocaulon pileatum, S. vesuvianum var. symphycheileoides, Umbilicaria hyperborea and U. subglabra. Lecidea phaeops and Rinodina teichophila, which are so far known from a single locality in the Czech Republic, were recorded on the screes and in the area of the castle ruin, respectively. The woodlands, which were strongly influenced by acid rain in the past, harboured several typical old-growth forest species such as Bacidia vermifera, Calicium viride, Chaenotheca brachypoda, C. chlorella and Sclerophora peronella. The bedrock of the Vranovské skály Nature Monument is made up of a mixture of acidic and calcareous sandstone rocks. The locality is rich in various crustose microlichens, many of which have only rarely been reported from the Czech Republic. Acrocordia conoidea, Arthonia calcicola, Bacidia arceutina, Bacidina egenula, Caloplaca albolutescens, C. dichroa, C. interfulgens, Diplotomma canescens, Lecania coeruleorubella, L. hutchinsiae, L. sylvestris, Leptogium plicatile and Verrucaria compacta represent the most valuable records. Sixty-one lichen species have been recorded historically, but 24 of them have not been confirmed recently. Most of them are rare epiphytes (Lobaria pulmonaria, Nephroma parile, Peltigera collina and several microlichens) and some are generally non-epiphytic lichens with cyanobacteria in the thallus or in the cephalodia (Peltigera horizontalis, P. polydactylon, Stereocaulon paschale, S. to- mentosum and Vahliella leucophaea). The current absence of these species was most probably caused by the acidification of their substrates by sulphur dioxide air pollution in the 20th century] |

Several of the species are endangered epiphytic lichens (L. allophana, L. glabrata, L. impudens and L. subcarpinea), some are rare or less known, predominantly lignicolous lichens (L. mughicola and L. sarcopidoides), two are typical high-mountain saxicolous species (L. albula and L. bicincta), two others occur on calcareous rocks (L. agardhiana and L. rouxii), and a few names represent rarely reported taxa on siliceous rocks (e.g. L. gisleriana, L. lojkaeana, L. pannonica and L. subcarnea). New Red List categories are suggested for some species. ] |

We focused on limestone and silicate rocks and rocky outcrops occurring in this lichenologically poorly known area. Caloplaca epierodens is new to the Czech Republic and Gyalecta geoica is new to Bohemia. One of two known Czech localities of the cyanolichen Placynthium caesium is located in the area. Several other rare and remarkable species were found in the region, for example Caloplaca erodens, C. limonia, Diplotomma porphyricum, Dirina stenhammarii, Lecania cuprea, Lecanora rouxii, Lepraria diffusa, L. nivalis, Leptogium teretiusculum, Lichinella nigritella, Metamelanea caesiella, Psora decipiens, Rhizocarpon petraeum, Solorina saccata, Toninia aromatica and Verrucaria caerulea ] |

Entosthodon hungaricus was growing in a saline grassland of the vegetation class Festuco-Puccinellietea in a rut made by a tractor. The place was flooded in early spring but already parched in May. The moss grew on open soil at the bottom of the rut together with the endangered annual vascular plants Cerastium dubium and Myosurus minimus. These plants prefer similar ecological conditions in inland saline meadows as E. hungaricus, which inhabits disturbed places with sufficient amounts of water in early spring that gradually dry out later. The new record represents the northernmost occurrence of E. hungaricus in the Pannonian region ] |

Although it has been addressed by only a few studies, some interesting patterns have already been observed. There are only scant data on the genome size of lichen symbionts, but future studies might reveal a similar ecological pattern as have already been found for other groups of organisms ] |
