KOUKOL O., HALASŮ V., JANOŠÍK L., MLČOCH P., POLHORSKÝ A., ŠANDOVÁ M., ZÍBAROVÁ L. (2020): Citizen science facilitates phylogenetic placement of old species of non-lichenised Pezizomycotina based on newly collected material.

abstract
During the informal Spring Micromyco 2019 meeting, we tested how newly obtained molecular barcodes of common or poorly known saprotrophic microfungi from more or less targeted collections may be useful for identification and taxonomic studies. Our aim was to obtain DNA sequences of fungi enabling their phylogenetic placement and routine identification in the future using molecular barcoding. As a result, DNA of four species was sequenced for the first time, among them Leptosphaeria acuta, for which a new synonym L. urticae is proposed. The new combination Koorchaloma melaloma is proposed for a species previously known as Volutella melaloma and its new synonym is K. europaea. This species is accommodated in the Stachybotryaceae. A detailed phenotypic description and phylogenetic placement are provided for Mytilinidion insulare, a resurrected species hitherto considered a later synonym of M. gemmigenum. Chalara insignis was placed in the Helotiales without any clear relationship to other members of this order. For another two helotialean species, a second referencing sequence was obtained. Our study showed that for some microfungi, due to the fundamental lack of molecular data, even a single molecular barcode may provide novel and important information on their phylogenetic and taxonomic placement. The results also illustrate that scientific progress can be made through collaboration between academic and amateur mycologists.
ŠANDOVÁ M. (2019): Revision of specimens of Melastiza deposited in the PRM herbarium. [Ascomycota, Pyronemataceae, Melastiza carbonicola, Melastiza cornubiensis, Melastiza flavorubens, Melastiza contorta, taxonomy, occurrence data.] Czech Mycology 71(2): 205-217 (published: 19th December, 2019)
abstract
Over 100 specimens deposited under Melastiza in the PRM herbarium (Prague, Czech Republic) were revised. They were identified as M. carbonicola, M. cornubiensis, M. flavorubens and M. contorta (84 specimens), remained unidentified (1 specimen) or were included in Scutellinia (23 specimens). Most of the previously published differences in hair and ascospore characters between M. carbonicola and M. cornubiensis were confirmed based on the studied material. Lists of revised specimens with collection data are given. The lists show that some differences in distribution between M. carbonicola and M. cornubiensis probably exist, but it is also taken into account that these are finds by various collectors who may prefer visiting different habitats. A final decision on the identity of M. carbonicola and M. cornubiensis is not made due to a lack of molecular data.
ŠANDOVÁ M. (2018): On the identity of Lachnum winteri (Ascomycota, Helotiales) [lachnoid fungi, Albotricha, type study, lectotypification, taxonomy] Czech Mycology 70(2): 169-183 (published: 10th December, 2018)
abstract
Syntypes of Lachnum winteri (specimens of the exsiccatae collection Rehm, Ascomyceten, No. 113) deposited in the herbaria S, K and M were examined. The syntypes contain the same species with short-stalked apothecia possessing whitish, pale yellow to yellow, sparsely warted and apically attenuated hairs corresponding to the genus Albotricha. The species differs from A. albotestacea not only in the colour of the apothecia and frequent presence of whitish subicular hyphae at the base of the stalks, but also in the structure of the ectal excipulum. The thinner ectal excipulum cell walls are considered to be the main character distinguishing the species from A. albotestacea. The species is regarded to be a good member of the genus Albotricha, hence the new combination A. winteri is proposed. A lectotype is designated and a description, line drawing and photographs are presented. The concept of L. winteri introduced by J. Velenovský is also discussed.
HOLEC J., KŘÍŽ M., POUZAR Z., ŠANDOVÁ M. (2015): Boubínský prales virgin forest, a Central European refugium of boreal-montane and old-growth forest fungi. [Mt. Boubín, Bohemian Forest, Czech Republic, Basidiomycota, Ascomycota, diversity, ecology, distribution] Czech Mycology 67(2): 157-226 (published: 10th September, 2015)
abstract
Boubínský prales virgin forest is the best-preserved montane Picea-Fagus-Abies forest in the Czech Republic. Its core area (46.67 ha), grown with original montane forest never cut nor managed by foresters, has been protected since 1858. It represents the centre of the present-day nature reserve (685.87 ha). A detailed inventory of its fungal diversity was carried out in 2013–2014. Ten segments differing in habitat and naturalness were studied (235 ha). The total number of species was 659, with the centre of diversity in the core area (503 species) followed by the neighbouring segments grown by natural forests minimally influenced by man. When literature and herbarium data are added, the total diversity reaches a total of 792 taxa. The locality represents a unique refugium for some borealmontane fungi (e.g. Amylocystis lapponica, Laurilia sulcata, Pholiota subochracea), a high number of rare species preferring old-growth forests (Antrodia crassa, A. sitchensis, Baeospora myriadophylla, Chrysomphalina chrysophylla, Fomitopsis rosea, Ionomidotis irregularis, Junghuhnia collabens, Skeletocutis odora, S. stellae, Tatraea dumbirensis), wood-inhabiting and mycorrhizal fungi confined to Abies (Panellus violaceofulvus, Phellinus pouzarii, Pseudoplectania melaena, Lactarius albocarneus), and a high number of indicators of well-preserved Fagus forests (e.g.Climacodon septentrionalis, Flammulaster limulatus, Pholiota squarrosoides). Several very rare fungi are present, e.g. Chromosera cyanophylla, Cystoderma subvinaceum and Pseudorhizina sphaerospora. The value of the local mycobiota is further emphasised by the high number of protected and Red List species. Comparison with other Central European old-growth forests has confirmed that Boubínský prales is a mycological hotspot of European importance.
