Families and genera assigned to Tremellomycetes have been mainly circumscribed by morphology for the yeasts also biochemical physiological characteristics. This phenotype-based classification is largely in conflict with molecular phylogenetic analyses. Here a framework proposed based on results of analyses from seven-genes dataset covering majority tremellomycetous closely related filamentous taxa. Circumscriptions taxonomic units at order, family genus levels recognised were quantitatively...
Abstract Parmelioid lichens are a diverse and ubiquitous group of foliose lichens. Generic delimitation in parmelioid has been state flux since the late 1960s with segregation large, heterogeneous genus Parmelia into numerous smaller genera. Recent molecular phylogenetic studies have demonstrated that some these new genera were monophyletic, not, others, previously believed to be unrelated, fell within single monophyletic groups, indicating need for revision generic delimitations. This study...
Fungal mycoparasitism—fungi parasitizing other fungi—is a common lifestyle in some basal lineages of the basidiomycetes, particularly within Tremellales. Relatively nonaggressive mycoparasitic fungi this group are general highly host specific, suggesting cospeciation as plausible speciation mode these associations. Species delimitation Tremellales is often challenging because morphological characters scant. Host specificity therefore great aid to discriminate between species but appropriate...
Abstract Recently, the number of cryptic species known has increased considerably, showing that diversity in many cases been underestimated past. Parmelia sulcata is a widely distributed and one most common taxa temperate Europe. The first intra-specific molecular studies on P. showed an unexpectedly high genetic variability. In present work, we study biodiversity this taxon including specimens from four continents using three markers (nuITS, nuIGS rDNA, partial β-tubulin gene). Two...
Dimorphism is a widespread feature of tremellalean fungi in general, but little-studied aspect the biology lichen-associated Tremella. We show that Tremella macrobasidiata and variae have an abundant yeast stage their life cycles occurs Lecanora lichens. Their sexual filamentous restricted to specific lichen: T. only forms basidiomata on chlarotera hymenia varia thalli. However, less can occur L. lichens, whilst all stages may be varia. Contrary hyphal stages, yeasts are distributed across...
Four new lichenicolous Tremella species are described and characterized morphologically molecularly. celata grows on Ramalina fraxinea, inducing the formation of inconspicuous galls, having hyphae with incomplete clamps. endosporogena develops intrahymenially in apothecia Lecanora carpinea, single-celled basidia clampless hyphae. diederichiana is name proposed for a micromorphologically close to T. christiansenii but small, pale galls thallus Lecidea aff. erythrophaea variae varia thallus,...
New data on the diversity and geographical distribution of lichenicolous Tremellales Filobasidiales in Nordic countries is presented. One new species, Tremella rhizocarpicola, formally described. pertusariae T. protoparmeliae are reported as to countries, Syzygospora physciacearum Iceland, rinodinae Sweden, caloplacae Norway. Nine species a number Swedish provinces, including Biatoropsis usnearum, bachmannii, S. physciacearum, caloplacae, cetrariicola, cladoniae, coppinsii, diploschistina,...
Millanes, A. M., Diederich, P., Westberg, M. & Wedin, 2016. Three new species in the Biatoropsis usnearum complex. — Herzogia 29: 337–354.Three of are formally described based on our previous molecular studies, and additional molecular, morphological, ecological data. protousneae sp. nov. is confined to Protousnea dusenii. minuta characterized by small brown black basidiomatal galls, growing Usnea barbata U. lapponica. hafellneri distinguished 2-celled basidia with cells that elongate...
The phylogenetic placement of the monotypic dematiaceous hyphomycete genus Xanthoriicola was investigated. Sequences nLSU region were obtained from 11 specimens X. physciae, which formed a single clade supported both by parsimony (91 %), and maximum likelihood (100 %) bootstraps, Bayesian Posterior Probabilities (1.0). closest relatives in analysis species Piedraria, while they those Friedmanniomyces. These three genera, along with Elasticomyces, Recurvomyces, Teratosphaeria, sequences...
Abstract Several specimens of a lichen-inhabiting Tremella , inducing the formation pale yellow, dark brown or black galls on species Diploschistes have been collected in three localities Sweden and one locality USA. Morphological molecular studies confirm that this material represents single species, which differs from other described combination gall morphology, basidium basidiospore sizes, presence thick-walled hyphidia, different host-selection. We consequently describe fungus as...
Abstract Flower scents are complex blends of volatile compounds often shaped by selection pressures exerted mutualistic and antagonistic interaction partners, but also phylogenetic constraints. So far, little is known about the relative effect signal on scent patterns, no study to date analyzed in multivariate semiquantitative patterns. We qualitative semi‐quantitative patterns flower 47 Sileneae (Caryophyllaceae) species using principal component analysis ( pPCA ) several indices univariate...
Fourteen species of lichenized or lichenicolous fungi are reported new to either Norway Sweden both countries. Several these rare and almost unknown. The are: Acarospora insignis (new Norway), A. pyrenopsoides (Norway, Sweden), versicolor (Norway), Calvitimela perlata (Sweden), Lecidea degeliana Nephroma helveticum Peltula placodizans Phacographa protoparmeliae Rhizocarpon pycnocarpoides Sarcogyne algoviae hypophaeoides Tephromela grumosa Tremella lobariacearum (Norway) wirthii (Sweden).

The lichen-forming genus Parmelia Acharius occurs worldwide but its centre of distribution is in the northern hemisphere and it widespread boreal-temperate Eurasia North America. Recent molecular work on has identified phylogenetic relationships within two major groups genus: P. saxatilis s. lat. sulcata However, little known about diversification historical biogeography these groups. Here we have used a dataset genetic markers 64 samples to estimate Parmelia. dated phylogeny provides...
A lectin from the lichen Evernia prunastri developing arginase activity (EC. 3.5.3.1) binds to homologous algae that contain polygalactosilated urease 3.5.1.5) in their cell walls acting as a ligand. The enzyme bound its ligand shows be inactive hydrolyze of arginine. Hydrolysis galactoside moiety intact with α-1,4-galactosidase 3.2.1.22) releases high amount D-galactose and impedes binding algal wall. However, use β-,4-galactosidase (EC.3.2.1.23) low amounts wall does not change pattern...
