Specimens morphologically identical to Gymnosporangium atlanticum have been found in Spain at four different locations. We describe these findings and provide an accurate description and illustrations. DNA sequences from these specimens are closely enough related to those from G. sabinae that the two species cannot be discriminated with the three DNA markers employed. © 2016. Mycotaxon, Ltd.

The concepts of the morphologically similar species Peziza arvernensis, P. pseudovesiculosa, P. pseudosylvestris, and P. domiciliana are revisited in light of new morphological and molecular data from freshly collected and herbarium specimens. Phylogenetic inference based on ITS nrDNA sequences suggests that P. arvernensis, P. pseudovesiculosa, and P. pseudosylvestris are monophyletic and that P. domiciliana represents an independent taxon. © 2016.

The new taxon Luteoamylascus aculeatus described in this article is proposed to accommodate two collections of a hypogeous ascomycete from central Spain, characterized by a tomentose yellowish peridium, labyrinth-like gleba filled with whitish hyphae, and intensely reacting amyloid asci. ITS, 28S, and RPB2 data suggest that this new taxon is an independent lineage proposed here as the new genus Luteoamylascus. Until now, this lineage was only known from ectomycorrhizal root tips and mitotic spore mats. In phylogenetic analyses, the Luteoamylascus lineage is placed close to the genera Amylascus, Pachyphlodes, and Scabropezia. Morphological data suggest an affinity with Amylascus. © 2016, German Mycological Society and Springer-Verlag Berlin Heidelberg.

The new species Hydnellum dianthifolium is described and illustrated from Pinus brutia forests in Cyprus and southern Italy. Evidence from ITS-based phylogenetic and morphological analyses, including scanning electron microscopy is provided, and the relevant literature is reviewed. The long-standing taxonomic problems associated with the closely affiliated taxa Hydnellum concrescens and H. scrobiculatum, both variously interpreted in the literature and as yet phylogenetically unresolved, are discussed. © 2016 Magnolia Press.

The new species Inocybe flavobrunnescens is described on the basis of morphological and genetic features. It is characterized by (sub)isodiametric spores; it has a variable number of low and obtuse knobs, lageniform cystidia, and habitat preference for thermophilous oak woods on calcareous soils. It is compared with type material of Inocybe xanthomelas and I. krieglsteineri, which share with the new species a darkening flesh and small to medium sized basidiomes. ITS analysis revealed a low intraspecific variability within each Inocybe lineage, suggesting their accommodation as independent species. On the basis of this DNA region, I. xanthomelas and I. krieglsteineri are closely related. The present work suggests also updating several names in public databases to accommodate the present taxonomic conclusions. A lectotype for I. xanthomelas is designated. © 2015, German Mycological Society and Springer-Verlag Berlin Heidelberg.

Species in the Inocybe praetervisa group are characterized by producing nodulose to angular basidiospores and a bulbous, marginate, white stipe devoid of any pinkish to reddish tinge. Species delimitation problems and common misinterpretations in the I. praetervisa group have not yet been resolved through type studies and analysis of molecular data. This study seeks to clarify the taxonomy and nomenclature of species around I. praetervisa. Analyses of the nuc rDNA internal transcribed regions (ITS) recovered two major groups within the I. praetervisa group that can be separated on the basis of cystidial morphology. The study of three authentic and topotypic specimens in the Bresadola herbarium revealed that the name I. praetervisa has been misapplied often. The ITS region of one of the specimens was obtained, and this specimen is designated as epitype in support of a lectotype. Inocybe rivularis is demonstrated to be a later synonym of I. praetervisa, while Inocybe phaeocystidiosa is the correct name for the species most often misdetermined as I. praetervisa. Inocybe salicis-herbaceae and I. praetervisa var. flavofulvida are shown to be synonyms of I. phaeocystidiosa based on ITS sequence data from type collections. A new species sister to I. phaeocystidiosa with a Mediterranean distribution is described as I. praetervisoides. Cystidial morphology, distribution of caulocystidia, basidiospore morphology and ecology are shown to be the main diagnostic characters for separating the species. Inocybe praetervisa and I. phaeocystidiosa have a transoceanic distribution in Europe and North America, whereas I. praetervisoides so far is known only from the Mediterranean region. © 2016 by The Mycological Society of America.

The new species Amplistroma erinaceum, collected on wood of Anacardium excelsum, is characterized by light cream-coloured, rostrate to spinose stromata, and immersed perithecia and long ostiolar necks. Its relationship to other Amplistroma species within the Amplistromataceae (incertae sedis, Ascomycota) are studied based on morphological, cultural, and molecular sequence data of the large subunit ribosomal DNA (28S rDNA). © 2013 German Mycological Society and Springer-Verlag Berlin Heidelberg.
