Description: In many lichen-forming fungi, molecular phylogenetic analyses lead to the discovery of cryptic species within traditional morphospecies. However, in some cases, molecular sequence data also questions the separation of phenotypically characterised species. Here we apply an integrative taxonomy approach ‒ including morphological, chemical, molecular, and distributional characters ‒ to re-assess species boundaries in a traditionally speciose group of hair lichens, Bryoria sect. Implexae. We sampled multilocus sequence and microsatellite data from 142 specimens from a broad intercontinental distribution. Molecular data included DNA sequences of the standard fungal markers ITS, IGS, GAPDH, two newly tested loci (FRBi15 and FRBi16), and SSR frequencies from 18 microsatellite markers. Datasets were analysed with Bayesian and maximum likelihood phylogenetic reconstruction, phenogram reconstruction, STRUCTURE Bayesian clustering, principal coordinate analysis, haplotype network, and several different species delimitation analyses (ABGD, PTP, GMYC, and DISSECT). Additionally, past population demography and divergence times are estimated. The different approaches to species recognition do not support the monophyly of the 11 currently accepted morphospecies, and rather suggest the reduction of these to four phylogenetic species. Moreover, three of these are relatively recent in origin and cryptic, including phenotypically and chemically variable specimens. Issues regarding the integration of an evolutionary perspective into taxonomic conclusions in species complexes, which have undergone recent diversification, are discussed. The four accepted species, all epitypified by sequenced material, are Bryoria fuscescens, B. glabra, B. kockiana, and B. pseudofuscescens. Ten species rank names are reduced to synonymy. In the absence of molecular data, they can be recorded as the B. fuscescens complex. Intraspecific phenotype plasticity and factors affecting the speciation of different morphospecies in this group of Bryoria are outlined.

Description: A revision of the classification of Geastrum sect. Geastrum is presented on the basis of an integrative taxonomic approach, which involves the study of morphological, molecular, ecological, and chorological data. Four DNA regions are analysed: the ITS and LSU nrDNA, rpb1, and atp6. Phylogenetic reconstructions include 95 ingroup samples and show five main clades, which are considered as five subsections, one of them proposed as new (G. subsect. Hungarica), and a total of 27 lineages recognizable at species level. Discriminant function analyses, ANOVAs and Tukey’s HSD tests on more than 500 basidiomata reveal the utility of several quantitative morphological characters for species delimitation. As a result of the combination of the different sources of taxonomic information, a revised taxonomy is presented and seven new species, viz., G. austrominimum, G. benitoi, G. britannicum, G. kuharii, G. meridionale, G. papinuttii, and G. thanatophilum, are proposed.

Description: We present a multilocus phylogeny of the class Dacrymycetes, based on data from the 18S, ITS, 28S, \nRPB1, RPB2, TEF-1\xce\xb1, 12S, and ATP6 DNAregions, with c. 90 species including the types of most currently accepted \ngenera. A variety of methodological approaches was used to infer phylogenetic relationships among the Dacrymycetes, from a supermatrix strategy using maximum likelihood and Bayesian inference on a concatenated dataset, \nto coalescence-based calculations, such as quartet-based summary methods of independent single-locus trees, \nand Bayesian integration of single-locus trees into a species tree under the multispecies coalescent. We evaluate \nfor the first time the taxonomic usefulness of some cytological phenotypic characters, i.e., vacuolar contents (vacuolar bodies and lipid bodies), number of nuclei of recently discharged basidiospores, and pigments, with especial \nemphasis on carotenoids. These characters, along with several others traditionally used for the taxonomy of this \ngroup (basidium shape, presence and morphology of clamp connections, morphology of the terminal cells of cortical/ \nmarginal hyphae, presence and degree of ramification of the hyphidia), are mapped on the resulting phylogenies \nand their evolution through the class Dacrymycetes discussed. Our analyses reveal five lineages that putatively \nrepresent five different families, four of which are accepted and named. Three out of these four lineages correspond \nto previously circumscribed and published families (Cerinomycetaceae, Dacrymycetaceae, and Unilacrymaceae), \nand one is proposed as the new family Dacryonaemataceae. Provisionally, only a single order, Dacrymycetales, \nis accepted within the class. Furthermore, the systematics of the two smallest families, Dacryonaemataceae and \nUnilacrymaceae, are investigated to the species level, using coalescence-based species delimitation on multilocus \nDNAdata, and a detailed morphological study including morphometric analyses of the basidiospores. Three species \nare accepted in Dacryonaema, the type, Da. rufum, the newly combined Da. macnabbii (basionym Dacrymyces \nmacnabbii), and a new species named Da. macrosporum. Two species are accepted in Unilacryma, the new U. bispora, and the type, U. unispora, the latter treated in a broad sense pending improved sampling across the Holarctic
