Cantharellus ilicis sp. nov., a new species from the Mediterranean Basin collected in evergreen Quercus forests
Cantharellus ilicis sp. nov., una nueva especie mediterránea recolectada en bosques perennes de Quercus. En este artículo se describe una nueva especie hallada en bosques
mediterráneos de Quercus, en suelo calcáreo. C. Ilicis es una especie caracterizada por su píleo amarillo naranja vivo en condiciones húmedas, estípite e himenóforo blanquecinos, fuerte
enrojecimiento y esporas largas en comparación con otras especies. Debido a la pileipelis formada por hifas de pared gruesa, C. ilicis se incluye en Cantharellus sección Cantharellus. Se aportan
descripciones macroscópicas y microscópicas detalladas, y la nueva especie es comparada con especies próximas, como C.ferruginascens y C. lilacinopruinatinatus. Se discute la variabilidad de algunos caracteres actualmente usados como diagnósticos en el grupo, tales como el color del píleo, la presencia de pruina y el enrojecimiento. Se propone una clave para la identificación de las especies
conocidas en el área mediterránea.Cantharellus ilicis sp. nov., a new species from the Mediterranean Basin collected in evergreen Quercus forests. In this article, a new species occurring in Mediterranean Quercus
forests, on calcareous soil, is described. C. Ilicis is characterized by its bright orange yellow pileus in wet conditions , whitish stipe and hymenophore, strong staining, as well as by the long basidiospores in
comparison with other species. Due to the thick-walled pileipellis hyphae, it is accommodated in the Cantharellus sect. Cantharellus. Macroscopic and microscopic detailed descriptions are provided and the new species is compared to closely related species, such as C. Ferruginascens and C. lilacinopruinatus. The variability of the pileus colour, the presence of coating and the staining, currently used as diagnostic characters, are discussed. A key is proposed for the species so far known in the Mediterranean Basin

Redescubrimiento del líquen amenazado Pseudocyphellaria aurata (Lobariaceae, Ascomycota) en la España peninsular
Lichens, as well as other organisms, should be considered important biodiversity components for the establishment of priorities in conservation biology. In this study, we report six new recent localities of the highly endangered, epiphytic macrolichen Pseudocyphellaria aurata in Spain: two in Navarra and four in A Coruña. Previous Spanish reports based on literature and herbarium specimens suggest a reduction of the distribution area of P. aurata and local extinction. Pseudocyphellaria aurata is known to be extinct in six localities, where it has not been observed since the middle of the 19th century (Cádiz, Pontevedra, Málaga). Four records reported for central Spain (Zaragoza, Salamanca, Teruel) are considered unplausible. The newly discovered populations are located in well-preserved patches of atlantic deciduous forest with strong oceanic influence, whose long-term ecological stability seems evident because of the presence of ancient trees. Nevertheless, these populations are small, fragmentary, and are threatened by habitat degradation, forestry and maybe fungal pathogens. Two populations, Intzola and Beba (Navarra and A Coruña, respectively), account for 75.7% of thalli. The localities with the highest number of trees colonized by P. aurata are Santa Leocadia and Beba in A Coruña. We reassessed the conservation status of this species concluding that conservation initiatives must be implemented to avoid its extinction in mainland Spain.Los líquenes son una parte importante de la biodiversidad que debería tenerse en cuenta para establecer prioridades en la biología de la conservación. En este estudio, se citan 6 nuevas localidades en las que el líquen epífito Pseudocyphellaria aurata, gravemente amenazado, ha sido hallado recientemente: 2 localidades en Navarra y 4 en A Coruña. Registros bibliográficos y especímenes de herbario previos sugieren que P. aurata ha sufrido una regresión en su área de distribución. Se considera P. aurata extinta en 6 localidades en las que no se ha observado desde mediados del siglo XIX (Cádiz, Pontevedra, Málaga). Cuatro citas del centro peninsular (Zaragoza, Salamanca, Teruel) no se consideran plausibles. Todas las nuevas localidades albergan manchas bien conservadas de bosque atlántico, en lugares con fuerte influencia oceánica y con presencia de árboles centenarios que sugieren continuidad ecológica. Sin embargo, las poblaciones de P. aurata descubiertas son pequeñas, fragmentadas, y están amenazadas por degradación de hábitat, explotación forestal y quizás, hongos patógenos. Dos poblaciones, Intzola y Beba (Navarra y A Coruña, respectivamente), albergan el 75,7 % de los talos. Las localidades en las que se han contabilizado más árboles colonizados por P. aurata son Santa Leocadia y Beba en A Coruña. Con los datos recopilados, evaluamos el estado de conservación de P. aurata, concluyendo que deben de implementarse iniciativas de conservación para evitar su extinción en la España peninsular
Hydnum pallidum Raddi, the Correct Name for H. albidum Peck in the Sense of European Authors and the Recently Described H. reginae Kibby, Liimat. & Niskanen
The systematics of the genus Hydnum have undergone important advances, and many new species have been described with the aid of molecular data. A revision of old names that refer to Hydnum s. str., considering the knowledge now available, might reveal prioritary names of recently described species. This study focuses on the study of names that refer to white Hydnum in Europe, among which earlier synonyms of Hydnum reginae (=Hydnum albidum s. auct. pl. eur.) are potentially found, a species characterized by producing white basidiomata and smaller spores than any other European species. Our revision revealed the existence of three earlier names based on European material, namely H. pallidum Raddi, H. album Fr. and H. heimii Maas Geest. The earliest of those, Hydnum pallidum, is epitypified using material from Tuscany (Italy), from where it was originally described, and hence, it becomes the correct name for H. albidum s. auct. pl. eur. A full description and photographs of H. pallidum are provided, and further comments on other names that refer to white Hydnum based on European material are made.This research was funded by the Spanish Research Agency (Agencia Estatal de Investigación, AEI) through the grant PID-2020116570GB-100
Finding needles in haystacks:Linking scientific names, reference specimens and molecular data for Fungi
DNA phylogenetic comparisons have shown that morphology-based species recognition
often underestimates fungal diversity. Therefore, the need for accurate DNA sequence
data, tied to both correct taxonomic names and clearly annotated specimen data, has
never been greater. Furthermore, the growing number of molecular ecology and microbiome
projects using high-throughput sequencing require fast and effective methods for
en masse species assignments. In this article, we focus on selecting and re-annotating a
set of marker reference sequences that represent each currently accepted order of Fungi.
The particular focus is on sequences from the internal transcribed spacer region in the
nuclear ribosomal cistron, derived from type specimens and/or ex-type cultures. Reannotated
and verified sequences were deposited in a curated public database at the
National Center for Biotechnology Information (NCBI), namely the RefSeq Targeted Loci
(RTL) database, and will be visible during routine sequence similarity searches with
NR_prefixed accession numbers. A set of standards and protocols is proposed to improve
the data quality of new sequences, and we suggest how type and other reference
sequences can be used to improve identification of Fungi.The Intramural Research Programs
