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.

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.

BANDINI D., OERTEL B. (2020): Three new species of the genus Pseudosperma (Inocybaceae).   [Agaricales, Inocybe, taxonomy, molecular phylogeny, ITS.]  Czech Mycology 72(2): 221-250   (published: 15th October, 2020)
  abstract   As a result of molecular phylogenetic and morphological analyses, three new species of the genus Pseudosperma, namely P. amabile, P. amoris and P. napaeanum, are described in detail along with illustrations of their macro- and micromorphology and a phylogenetic tree. In addition, to ensure a correct interpretation of the species identity in comparison with morphologically similar species, the holotype of P. flavellum, as well as an isoparatype of P. spurium and isotypes of P. aureocitrinum and P. copriniforme have been examined, and of the latter two species also an ITS sequence was obtained. A drawing of the microscopical details of all four type specimens is given.

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. The new species is compared with other four related species of the section, Octospora albocincta (Berk, et Curt. ap. Berk.) Caillet et Moyne, Octospora rutilans (Fr.) Dennis et Itzerott, Octospora vivida (Nylander) Dennis et Itzerott and Octospora aplanodictyon (Kobayasi) J. Moravec based on Aleuria aplanodictyon Kobayasi. The latter is here reported for the first time from Central Europe (Czech Republic). Features of the new species are illustrated by line drawings and SEM photomicrographs. Ascospore ornamentation of the other species treated here has also been studied and line drawings of their ascospores accompany the paper.

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.
