Abstract	Harpidium longisporum is proposed as a new species. It is characterized by an areolate, mainly black thallus with trebouxioid algae, K+ blue-purple pigmented parts, pycnoascocarps forming aspicilioid apothecia, with moniliform paraphyses, unitunicate-rostrate, thick-walled asci and long sigmoid, lunate to falcate or irregularly curved and twisted ascospores, growing on steps of a vertical, intermittently moist, gneiss rock face. The genus Harpidium now comprises four species worldwide and, based on the selected specimens, a genus synopsis, a comparative table and a key to the species are included.

Abstract	Large phylogeographic studies on lichens are scarce, and none involves a single species within which different lineages show fixed alternative dispersal strategies. We investigated Bryoria fuscescens (including B. capillaris) in Europe and western North Africa by phenotypically characterizing 1400 specimens from 64 populations and genotyping them with 14 microsatellites. We studied population structure and genetic diversity at the local and continental scales, discussed the post‐glacial phylogeography, and compared dispersal capacities of phenotypes with and without soralia. Our main hypothesis is that the estimated phylogeography, migration routes, and dispersal capacities may be strongly biased by ancestral shared alleles. Scandinavia is genetically the richest area, followed by the Iberian Peninsula, the Carpathians, and the Alps. Three gene pools were detected: two partially linked to phenotypic characteristics, and the third one genetically related to the American sister species B. pseudofuscescens. The comparison of one gene pool producing soredia and one not, suggested both as panmictic, with similar levels of isolation by distance (IBD). The migration routes were estimated to span from north to south, in disagreement with the assessed glacial refugia. The presence of ancestral shared alleles in distant populations can explain the similar IBD levels found in both gene pools while producing a false signal of panmixia, and also biasing the phylogeographic reconstruction. The incomplete lineage sorting recorded for DNA sequence loci also supports this hypothesis. Consequently, the high diversity in Scandinavia may rather come from recent immigration into northern populations than from an in situ diversification. Similar patterns of ancestral shared polymorphism may bias the phylogeographical reconstruction of other lichen species.

Abstract	The species of the Parmelia saxatilis complex occurring in the Iberian Peninsula were revised. Eight species are accepted, including a new species found in southern Spain, described as P. rojoi A. Crespo, V. J. Rico & Divakar. The new species, which forms a sister-group relationship with P. saxatilis s. str., is rare in the Iberian Peninsula and is restricted to higher altitudes of northern and central Spain. Parmelia rojoi differs from P. saxatilis by generally narrower isidia and a more fragile thallus. The segregation of the new species is also supported by ITS (rDNA) and Mcm7 (MS456) phylogeny and multispecies coalescent-based approaches, including StarBEAST and BP&P. Furthermore, the divergence of P. rojoi is dated back to the Pleistocene, c. 2.13 Ma. A key to the identification of species from the P. saxatilis complex with their diagnostic features is provided. All species of the complex known from Europe are also found in the Iberian Peninsula. We hypothesize that P. rojoi is a relict species that survived the Pleistocene glaciations in refugia in Spain and has been unable to extend its distributional range in postglacial periods.

Abstract	A taxonomic study of the species with nutant, pleurotoid and cyphelloid basidiomata of the genus Arrhenia in the Iberian Peninsula is presented. This study is based on the examination of recent specimens collected in the field and from dried herbarium collections. Five species and one variety of this genus are recognized on the basis of morphological and ecological features: Arrhenia acerosa var. acerosa, A. acerosa var. tenella, A. auriscalpium, A. lobata, A. retiruga and A. spathulata. Arrhenia auriscalpium is new to Spain, where it is not restricted to alpine zones of the Eurosiberian region and is more common in the Mediterranean region than previously reported. In contrast, A. acerosa var. tenella currently is known from the Eurosiberian subalpine belt and represents the first report to the Iberian Peninsula, and A. retiruga is known only from the mesomediterranean to supramediterranean belts of the Mediterranean region. Arrhenia acerosa var. acerosa, A. lobata and A. spathulata are widespread in both the Eurosiberian and the Mediterranean regions. Non-Iberian materials of A. acerosa var. tenella and A. spathulata also were studied for comparison. Cyphella cochlearis var. subsessilis, Dictyolus lagunae, Leptoglossum muscigenum var. azonum and Pleurotellus acerosus var. tenellus are lectotypified. Cyphella cochlearis var. subssesilis, Dictyolus lagunae and Leptoglossum muscigenum var. azonum are synonymized with Arrhenia spathulata, and Cyphella cochlearis var. auriformis is placed in synonymy with A. auriscalpium. These taxa are illustrated, described and discussed, based on Iberian material with emphasis on features of the basidioma, pigment of the pileipellis, presence or absence of clamps and shape and size of the basidiospores. A diagnostic key also is given.

Abstract	Four new lichenicolous Tremella species are described and characterized morphologically and molecularly. Tremella celata grows on Ramalina fraxinea, inducing the formation of inconspicuous galls, and having hyphae with incomplete clamps. Tremella endosporogena develops intrahymenially in the apothecia of Lecanora carpinea, having single-celled basidia and clampless hyphae. Tremella diederichiana is the name proposed for a species micromorphologically close to T. christiansenii but inducing the formation of small, pale galls on the thallus and apothecia of Lecidea aff. erythrophaea. Tremella variae grows on Lecanora varia thallus, instead of on the apothecia, as do the other known Tremella species parasitizing Lecanora s.l. Phylogenetic relationships and host specificity of these species are investigated and compared with other taxa that show morphological resemblances, phylogenetic affinities or similar hosts. The formation of mitotic conidia inside old basidia (endospores), which is a poorly known reproductive strategy in the Basidiomycota, is also a distinctive character of Tremella endosporogena. A discussion on the reproductive role and systematic implications of endospores is included.

Abstract	The results of the first molecular phylogenetic study of Pseudephebe are presented; a three-locus phylogeny. The genus is confirmed as monophyletic within the alectorioid clade of Parmeliaceae. Two major clades were recovered, which can be assigned to the two traditional taxa, P. minuscula and P. pubescens, with modifications of the species delimitation, especially the variable P. minuscula. These species are cryptic and cannot be confidently distinguished morphologically due to phenotypic convergence. Therefore, the use of P. pubescens aggr. is recommended for samples not molecularly analyzed. Contrary to previous studies, specimens of both species might have indistinct pseudocyphellae and also contain lichen substances; norstictic acid was detected in c. 60% of specimens tested. An SSU 1516 Group I intron is usually present in P. minuscula but always absent in P. pubescens. The species-level nomenclature is summarized and sequenced reference specimens (RefSpec) for both Pseudephebe species are selected. Sequences from Bryoria mariensis established that this name was a synonym of P. minuscula.

Abstract	Taxonomic identifications in some groups of lichen-forming fungi have been challenge largely due to the scarcity of taxonomically relevant features and limitations of morphological and chemical characters traditionally used to distinguish closely related taxa. Delineating species boundaries in closely related species or species complexes often requires a range of multisource data sets and comprehensive analytical methods. Here we aim to examine species boundaries in a group of saxicolous lichen forming fungi, the Aspiciliella intermutans complex (Megasporaceae), widespread mainly in the Mediterranean. We gathered DNA sequences of the nuclear ribosomal internal transcribed spacer (nuITS), the nuclear large subunit (nuLSU), the mitochondrial small subunit (mtSSU) ribosomal DNA, and the DNA replication licensing factor MCM7 from 80 samples mostly from Iran, Caucasia, Greece and eastern Europe. We used a combination of phylogenetic strategies and a variety of empirical, sequence-based species delimitation approaches to infer species boundaries in this group. The latter included: the automatic barcode gap discovery (ABGD), the multispecies coalescent approach *BEAST and Bayesian Phylogenetics and Phylogeography (BPP) program. Different species delimitation scenarios were compared using Bayes factors species delimitation analysis. Furthermore, morphological, chemical, ecological and geographical features of the sampled specimens were examined. Our study uncovered cryptic species diversity in A. intermutans and showed that morphology-based taxonomy may be unreliable, underestimating species diversity in this group of lichens. We identified a total of six species-level lineages in the A. intermutans complex using inferences from multiple empirical operational criteria. We found little corroboration between morphological and ecological features with our proposed candidate species, while secondary metabolite data do not corroborate tree topology. The present study on the A. intermutans species-complex indicates that the genus Aspiciliella, as currently circumscribed, is more diverse in Eurasia than previously expected.

Abstract	Until recently, superhydrophobicity was considered as a hint to predict surface icephobicity, an association of concepts that is by no means universal and that has been proven to depend on different experimental factors and material properties, including the actual morphology and chemical state of surfaces. This work presents a systematic study of the wetting and freezing properties of aluminum Al6061, a common material widely used in aviation, after being subjected to nanosecond pulsed IR laser treatments to modify its surface roughness and morphology. All treated samples, independent of their surface finishing state, presented initially an unstable hydrophilic wetting behavior that naturally evolved with time to reach hydrophobicity or even superhydrophobicity. To stabilize the surface state and to bestow the samples with a permanent and stable hydrophobic character, laser-treated surfaces were covered with a thin layer of CFx prepared by plasma-enhanced chemical vapor deposition. A systematic comparison between freezing delay (FD) and wetting properties of water droplets onto these plasma-/polymer-modified laser-treated surfaces that, under conditions where a heterogeneous nucleation mechanism prevails, surface morphology rather than the actual value of the surface roughness parameter the key feature for long FD times. In particular, it is found that surface morphologies rendering a Cassie–Baxter wetting regime longer FDs than those characterized by a Wenzel-like wetting state. It is that laser treatment, with or without additional coverage with thin CFx coatings, affects wetting and ice formation behaviors and might be an efficient procedure to mitigate icing problems on metal surfaces.
