Amanita vladimirii, a new species in sect. Vaginatae, is described and illustrated based on collections from the Czech Republic and France. The distinctive sequences of the LSU, ITS and tef1-α genetic markers, support the status of A. vladimirii as a new species. Amanita vladimirii is characterised by a greyish pileus striate at margin, a whitish stipe; and a relatively thin, but firm, membranous volva which is externally white with brownish yellow tinges where touched and internally is white-beige or greyish beige. Microscopically, the universal veil is composed of 3 layers; globose basidiospores; a ramose subhymenium; lamellar trama reduced to a mediostratum composed of parallel elements and a pileipellis without a differentiated subpellis.

During the investigation of fungal microbiome associated with boxwood in the Czech Republic, samples from Buxus sempervirens L. (Buxaceae) plants were collected and used for isolation. Two fungal strains were proposed as a new species Pyrenochaetopsis kuksensis based on morphology as well as phylogenetic analyses of ITS, LSU, rpb2, and tub2 sequence data. Detailed descriptions and phylogenetic relationships of the new taxon are provided.

A new species of Mycetophilidae (Diptera), Acomopterella martinovskyi sp. n., is described from the Czech Republic and Austria. This is the first record of the genus from the Palaearctic region. Its relationships with other genera and variation in wing characters are briefly discussed. A new combination and synonymy is proposed: Acomopterella fallax (Sherman, 1921) comb.n. = Acomopterella arnaudi Zaitzev, 1989 syn.n.

AbstractEpipelic cyanobacteria were studied in bottom sediments from ponds and lakes in the United Kingdom and the Czech Republic, covering a trophic gradient from deep, oligotrophic, glacial lakes to shallow, eutrophic, urban manmade ponds. Although many planktic species were observed, the most frequently occurring cyanobacteria were the motile filamentous genera Oscillatoria, Phormidium, Pseudanabaena and Komvophoron. These genera represent autochtonous epipelic assemblages, occurring in upper surface layers of the sediments throughout the year and exhibiting seasonal variation in their abundancy. The occurrence of individual Komvophoron species was influenced by sediment quality, particularly the proportions of fine mud and organic detritus. A new species Komvophoron hindakii sp. nov. is described. Morphological features, autecology and occurrence of all the Komvophoron-like morphospecies found are discussed.

The new lichenicolous hyphomycete, Monodictys epilepraria, is described from thalli of several Lepraria species. It is known from the Czech Republic, Great Britain, Lithuania, Poland, Spain and Sweden, and appears to be widespread, but probably much overlooked. The new species is characterized by relatively small, brown, muriform, smooth-walled conidia developing on decolourized patches of the host.

AbstractProblematic phosphatic sclerites Eurytholia are reported for the first time from the Middle Devonian. Unequivocal sclerites were observed in limestones of Emsian to late Eifelian age in six localities of the Barrandian area of the Central Bohemia of the Czech Republic. Formerly observed size and shape variations of Eurytholia sclerites prevent formal description of a new species on few specimens of Emsian and Eifelian age. Therefore the new specimens are identified as Eurytholia aff. bohemica. Their presence indicates longer time range of the Eurytholia animal, covering not only the Ordovician, the Silurian and the earliest Devonian as known formerly, but also late Lower Devonian and the Middle Devonian. Similar features in morphology and histology of Eurytholia indicate relationship to a conodont Pseudooneotodus and a support suggestion about the vertebrate origin of Eurytholia sclerites.

Japewia aliphatica is described as a new species. It is characterized by the usually brown, often areolate, blastidiate to sorediate-blastidiate, rarely fertile thallus containing unknown fatty acid(s). It grows on acidic bark of broad-leaved trees in mainly in montane forests, and is known from Austria, the Czech Republic, Germany, Norway, Russia (European part of the Caucasus), Slovakia and Ukraine. The new species is well characterized by its morphological, chemical and molecular (nrITS, mtSSU) traits. Systematic placement of Japewia is briefly discussed and its position within Lecanoraceae confirmed.
