SOCHOROVÁ Z., ECKSTEIN J., SOCHOR M. (2024): Octospora pulchrispora (Pezizales) – a new bryophilous species on Cynodontium polycarpon   [bryoparasitic Pezizales, bryophilous ascomycetes, Rhabdoweisiaceae, rhizoid galls, vital taxonomy.]  Czech Mycology 76(1): 45-62   (published: 3rd May, 2024)
  abstract   Octospora pulchrispora Sochorová et Eckstein is described as a new species based on finds from the Czech Republic. It features a remarkable ascospore ornamentation formed by low, branching, cyanophilous ridges. It parasitises the acrocarpous moss Cynodontium polycarpon (Rhabdoweisiaceae) and induces galls on the rhizoids. In the phylogenetic analysis based on the LSU, SSU and EF1α loci, O. pulchrispora formed a highly supported clade with Octospora gyalectoides agg., O. leucoloma, O. gemmicola, O. axillaris, O. excipulata, O. bridei and two undescribed Octospora species.

NÉMETH C., ECKSTEIN J., SOCHOR M. (2022): Disentangling the taxonomy of Octospora meslinii (Pezizales), a bryophilous ascomycete on Grimmia pulvinata.   [bryoparasitic fungi, EF1α, Grimmia pulvinata, LSU, SSU.]  Czech Mycology 74(1): 1-24   (published: 1st January, 2022)
  abstract   The bryophilous ascomycete Octospora meslinii is a rarely reported species growing exclusively in cushions of the saxicolous moss Grimmia pulvinata. The taxon has been misunderstood in the past and hitherto reliably only reported from France and Germany. Many recent collections from Hungary have made it possible to get a better understanding of O. meslinii, which is comprehensively described and illustrated in this paper. Because of the lack of original material, we designate an illustration in the protologue as the lectotype and one of the recent collections as the epitype of this fungus. Octospora meslinii is compared with other species of Octospora growing in the same type of habitat or having similar ascospores. The most closely related species to O. meslinii is O. pseudoampezzana. Both share apothecia with blackish pigmentation, a unique feature compared to bryophilous Pezizales as a whole, ellipsoid ascospores ornamented with isolated warts, moss hosts in the family Grimmiaceae, and the infection inducing galls on the rhizoids. A phylogenetic analysis using the EF1α, LSU and SSU rDNA loci confirms our morphological findings showing that O. meslinii forms a monophyletic clade with O. pseudoampezzana, whereas other species with which O. meslinii was confused in the past, e.g. O. similis, are related only distantly.

EGERTOVÁ Z., ECKSTEIN J., VEGA M. (2015): Lamprospora tuberculata, Octospora ithacaensis, O. orthotrichi and O. affinis - four bryoparasitic ascomycetes new to the Czech Republic.   [bryoparasitic Pezizales, Ascomycota, Pyronemataceae, rhizoid galls, central Europe]  Czech Mycology 67(2): 119-133   (published: 2nd July, 2015)
  abstract   Four bryoparasitic ascomycetes, Lamprospora tuberculata, Octospora ithacaensis, O. orthotrichi and O. affinis were recently found in the Czech Republic for the first time. For each species, basic description of macroscopical and microscopical characters, information about its habitat, distinguishing features of similar species as well as notes on the distribution in Europe are provided. Furthermore, apothecia, spores and parasitising structures are illustrated. The following parasite-host relationships were observed: L. tuberculata on Pleuridium subulatum, O. ithacaensis on Marchantia polymorpha, O. orthotrichi on Orthotrichum diaphanum and O. affinis on Orthotrichum affine.One locality of L. tuberculata, two of O. ithacaensis, eight of O. orthotrichi and one of O. affinis were found. Internal cavities in the warts of spores in O. affinis and L. tuberculata are newly reported as well as the infection of leaf cells in O. affinis.

MORAVEC J. (1997): Fungi of the Kilimanjaro - II. Octospora kilimanjarensis sp. nov., a new species of the section Neottiellae (Discomycetes, Pezizales).   [Octospora kilimanjarensis sp. nov., Octospora sect. Neottiellae, Discomycetes, taxonomy]  Czech Mycology 49(3-4): 149-161   (published: 23rd May, 1997)
  abstract   Octospora kilimanjarensis sp. nov. is described from a rain forest of the Kilimanjaro, Tanzania. The taxonomy is discussed and Octospora kilimanjarensis is placed in these c­ tion Neottiellae Caillet et Moyene of the bryophilous genus Octospora Hedwig.

DZHAGAN V.V., SHCHERBAKOVA YU.V., LYTVYNENKO YU.I. (2021): New and noteworthy records of operculate discomycetes of the Pyronemataceae (Pezizales) from Ukraine.   [Ascomycota, Pezizomycetes, Aleurina subvirescens, Ramsbottomia asperior, Smardaea purpurea, biodiversity, Carpathian Biosphere Reserve.]  Czech Mycology 73(2): 137-150   (published: 30th July, 2021)
  abstract   The article reports new data on the occurrence of three species of apothecial ascomycetes of the Pyronemataceae family collected in the Carpathian Biosphere Reserve. Aleurina subvirescens and Smardaea purpurea were found in Ukraine for the first time, Ramsbottomia asperior was previously found by us also at other localities in Ukraine, including the Carpathian Biosphere Reserve, but without any details and illustrations. For each species a description of the Ukrainian specimens, collection data, macro- and micrographs are provided here. In addition to morphological characters, ecological characteristics and data on the general distribution of these species are briefly discussed.

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.

SUKOVÁ M. (2005): A revision of selected material of lignicolous species of Brunnipila, Capitotricha, Dasyscyphella and Neodasyscypha from the Czech Republic.   [Bohemia, Moravia, taxonomy, nomenclature, Dasyscyphus, Lachnella brunneola var. fagicola]  Czech Mycology 57(1-2): 139-172   (published: 31st August, 2005)
  abstract   Selected material of lignicolous species of Brunnipila, Capitotricha, Dasyscyphella and Neodasyscypha from the Czech Republic was studied. Possible forms of Brunnipila fuscescens s.l. and their characters are outlined. The generic name Dasyscyphus (Nees) ex Gray typified by Korf using D. virgineus belongs to the synonymy of Lachnum. For its later homonym, Dasyscyphus Fuckel (nom. illeg.), the nomen novum Neodasyscypha Suková et Spooner is proposed. The replacing name Neodasyscypha was already earlier proposed by Spooner, but was published invalidly by him. The new combinations Neodasyscyphacerina (Pers.: Fr.) Spooner and Neodasyscyphasubciboria(Rodway) Spooner are published.

MORAVEC J. (1994): Melastiza (Boud.) comb. et stat. nov. - a subgenus of the genus Aleuria Fuck. emend. nov. (Discomycetes, Pezizales).   [Aleuria, subgen. Melastiza, Pezizales, taxonomy]  Czech Mycology 47(4): 237-259   (published: 16th February, 1995)
  abstract   Relations between the genera Melastiza Boud. and Aleuria Fuck, are discussed. Examination of a number of collections of most species of both genera including the relevant type material has confirmed the opinion that the coloured outgrowths on there ceptacles of species of Melastiza are not reliable and sufficient for generic delimitation and, as a result, a new emendation of the genus Aleuria Fuck, is proposed. The genus is divided into two subgenera: subgen. Aleuria and subgen. Melastiza (Boud.) comb, et stat. nov.The discussed mutual relations and leading features, especially a variability of the colour and the wall thickness of the excipular hyphae and hyphoid hairs in Melastiza, similar shapes of the hyaline hyphae and hyphoid hairs in Aleuria, the same type of ascospores and excipular structure, the same carotenoid composition in paraphyses, and the same habitat, are considered an evidence for the generic identity. Reexaminations of the type material (NY, K) of Peziza cornubiensis Berkeley et Broome [= Melastiza cornubiensis (Berk, et, Br.) J. Moravec (1992b)], and the type (K) of Peziza chateri W. G. Smith [= Melastiza chateri (W. G. Smith) Boud.], have confirmed the identity of both fungi . Consequently, new combinations - Aleuria cornubiensis (Berk, et Br.) comb, nov., Aleuria carbonicola (J. Mor.) comb, nov., Aleuria flavida (Thind et Kaushal) comb, nov., Aleuria flavorubens (Rehm) comb, nov., Aleuria boudieri (v. Hohnel in Rehm) comb. nov. and Aleuria scotica (Graddon) comb. nov. are proposed. A Nepal collection of Aleuria rubra Batra [=Melastiza rubra (Batra) Maas Geesteranus] has also been examined. Aleuria latispora spec. nov. based on a collection from Central Asia is described as a new species of this subgenus too. Notes on the taxonomy, and descriptions and illustrations of all the taxa including SEM photomicrographs of ascospores accompany the paper.

MORAVEC J. (1982): Daleomyces phillipsii in Czechoslovakia (Discomycetes, Pezizaceae).  Česká Mykologie 36(2): 109-113   (published: 1982)
  abstract   The amyloid reaction with Melzer’s solution has been studied in the hyphae of basidiocarps in selected Amanita species. The species of the subgenus Amanita (with no amyloid reaction of the spore-walls) have given diverse reactions in hyphae of basidiocarps. The species from the section Amanita (Amanita friabilis, A. gemmata, A. muscaria, A. pantherina and A. regalis) have the amyloid substance in the plasma; it is particularly visible at the boundary of trama of pileus and stipe. In the section Vaginatae the reaction of hyphae was either positive (A. beckeri, A. caesarea, A. crocea, A. inaurata) or negative (A. fulva, A. mairei, A. umbrinolutea, A. vaginata). No amyloid substance was found in the plasma in species of subgenus Lepidella which show amyloid reaction in their spore-walls.
