A preliminary account of the Cucurbitariaceae
(ScienceDirect, 2018-06) Jaklitsch, W.M.; Checa, J.; Blanco, M.N.; Olariaga, I.; Tello, S.; Voglmayr, H.
Fresh collections, type studies and molecular phylogenetic analyses of a multigene matrix of partial nuSSU-ITS-LSU rDNA, rpb2, tef1 and tub2 sequences were used to evaluate the boundaries of Cucurbitaria in a strict sense and of several related genera of the Cucurbitariaceae. Two species are recognised in Cucurbitaria and 19 in Neocucurbitaria. The monotypic genera Astragalicola, Cucitella, Parafenestella, Protofenestella, and Seltsamia are described as new. Fenestella is here included as its generic type F. fenestrata (= F. princeps), which is lecto- and epitypified. Fenestella mackenzei and F. ostryae are combined in Parafenestella. Asexual morphs of Cucurbitariaceae, where known, are all pyrenochaeta- or phoma-like. Comparison of the phylogenetic analyses of the ITS-LSU and combined matrices demonstrate that at least rpb2 sequences should be added whenever possible to improve phylogenetic resolution of the tree backbone; in addition, the tef1 introns should be added as well to improve delimitation of closely related species
Advances in the knowledge of the Inocybe mixtilis group (Inocybaceae, Agaricomycetes), through molecular and morphological studies
(Ingentaconnect, 2018-10-18) Esteve-Raventós, F.; Bandini, D.; Oertel, B.; González, V.; Moreno, G.; Olariaga, I.
Inocybe mixtilis constitutes a complex of species characterized by nodulose-angulose spores, absence of cortina and a more or less bulbous marginate stipe that is not darkening when desiccated. In order to elucidate species limits within the I. mixtilis complex, an ITS-RPB2 phylogeny was performed and interpreted using morpho- logical and ecological characters. Six supported clades were obtained in our analyses that correspond to I. mixtilis, I. subtrivialis, and four new species to science: I. ceskae, I. johannis-stanglii, I. nothomixtilis and I. occulta. Species within this complex can be morphologically recognized through a unique combination of morphological characters, such as the spore shape, cystidial length and shape, presence and development of the velipellis and pileus colour and viscidity. Nevertheless, those characters overlap, especially among I. mixtilis, I. ceskae and I. occulta, and intermediate collections are therefore more reliably identified through ITS-sequencing. Two species, I. ceskae and I. occulta are present in both North America and Europe, while the rest are so far only known in Europe, or Europe and Asia (I. mixtilis). All species, except I. johannis-stanglii, seem to be able to establish ectomycorrhizal associa- tion both with conifers and angiosperms. Descriptions, colour illustrations and a key to all known species in the I. mixtilis group are provided.

Identifying and naming the currently known diversity of the genus Hydnum, with an emphasis on European and North American taxa
(Taylor & Francis, 2018) Niskanen, T.; Liimatainen, K.; Nuytinck, J.; Kirk, P.; Olariaga, I.; Garibay-Orijel, R.; Norvell, L.; Huhtinen, S.; Kytövuori, I.; Ruotsalainen, J.; Niemelä, T.; Ammirati, J.F.; Tedersoo, L.
In this study, 49 species of Hydnum are recognized worldwide. Twenty-two of them are described here as new species. Epitypes are proposed for H. repandum and H. rufescens. The majority of the species are currently known only from a single continent. The barcodes produced in this study are deposited in the RefSeq database and used as a basis to name species hypotheses in UNITE. Eleven infrageneric clades recovered in a phylogenetic analysis are supported by morphological characteristics and formally recognized: subgenera Alba, Hydnum, Pallida, and Rufescentia; sections Hydnum, Olympica, Magnorufescentia, and Rufescentia; and subsections Mulsicoloria, Rufescentia, and Tenuiformia.
Lichinodium is a new lichenized lineage in the Leotiomycetes
(SpringerLink, 2018-12-13) Prieto, M.; Schultz, M.; Olariaga, I.; Wedin, M.
Here, we show that Lichinodium (Lichinaceae, Lichinomycetes, Ascomycota) constitutes a formerly unrecognized lineage within the Leotiomycetes, thus being the first lichenized lineage recognized in the superclass Sordariomyceta (Leo- tiomycetes, Laboulbeniomycetes and Sordariomycetes). To infer the position of Lichinodium, we constructed two mul- tilocus phylogenies based on six and five gene regions (nuLSU rDNA, nuSSU rDNA, mtSSU rDNA, RPB1, RPB2 and MCM7) including main Pezizomycotina groups in the first analysis and focusing secondly on a comprehensive selection of Sordariomyceta. The results show that Lichinodium is sister to Leotiaceae. We discuss the morphological and ecological similarities between Lichinodium and other Leotiomycetes, and describe the new order Lichinodiales and family Lichinodiaceae. The sister relationship between Sordariomycetes and Laboulbeniomycetes is here supported as it is the relationship between this clade and the Leotiomycetes. The results also support the polyphyly of Helotiales, the recognition of the Leotiales in a strict sense or the inclusion of the Triblidiales in Leotiomycetes. The photobionts of Lichinodium were sequenced for two genetic markers (rbcLX and 16S rDNA) and identified as Rhizonema, a recently described genus of filamentous cyanobacteria belonging to Nostocaceae. TEM studies revealed that the mycobiont-cyanobiont interface in Lichinodium does not produce haustoria, thus differing from a typical Lichinomycete (e.g. Ephebe).
Pseudosclerococcum golindoi gen. et sp. nov., a new taxon with apothecial ascomata and a Chalara-like anamorph within the Sclerococcales (Eurotiomycetes)
(SpringerLink, 2019) Olariaga, I.; Teres, J.; Martín, J.; Prieto, M.; Baral, H.-O.
Sclerococcales encompasses a heterogeneous group of fungi, with most of the species included in the genus Sclerococcum (= Dactylospora). Species of Sclerococcum are characterized by having apothecial ascomata with asci covered by an external hemiamyloid gelatin and a thick euamyloid apical cap, while lacking an inner amyloid wall thickening. Asexual morphs, known for few species, are sporodochial. In this study, we describe Pseudosclerococcum golindoi as a new genus and species sister to Sclerococcum in a multigene phylogeny (nuITS, nuLSU, nuSSU, mtSSU). The fungus produces ascomata similar to those of Sclerococcum, but differs in having cylindrical asci embedded in an overall hemiamyloid gelatin with a fissitunicate dehiscence. Unlike Sclerococcum, Pseudosclerococcum golindoi produces a Chalara-like asexual morph. A possible symbiotic association of P. golindoi with Ascocoryne cylichnium is discussed. The presence of a hemiamyloid gelatin on lateral wall of asci, so far largely overlooked, is reported for some Sclerococcum species. Based on ascal characters and interpretation of the phylogenetic analyses, 14 names assigned to saprotrophic species, previously placed in Dactylospora, are combined in Sclerococcum.
