| 8 | Turbo-taxonomy to assemble a megadiverse lichen genus:seventy new species of Cora(Basidiomycota:Agaricales:Hygrophoraceae),honouring David Leslie Hawksworth’s seventieth birthday显示文摘Following a large-scale phylogenetic study of the lichenized genus Cora(Basidiomycota:Agaricales:Hygrophoraceae),we formally describe 70 new species,honouring the seventieth birthday of David Leslie Hawksworth,one of the preeminent figures in mycology and lichenology in the past 50 years.Based on an updated phylogeny using the ITS fungal barcoding locus,we now recognize 189 taxa in a genus that until recently was considered to represent a single species;including this contribution,92 of these are formally recognized,including five taxa based on historical names or collections that have not been sequenced.Species of Cora can be recognized by a combination of morphological(size,colour,lobe configuration,surface hairs,hymenophore size and shape),anatomical(thallus thickness,cortex structure,photobiont type,hyphal papillae),and ecogeographical features(substrate,habitat,distribution),and a keytable allowing the identification of all accepted taxa is provided.The new species are:Cora accipiter Moncada,Madrin˜a´n&Lücking spec.nov.,C.applanata Moncada,Soto-Medina&Lücking spec.nov.,C.arachnodavidea Moncada,Dal Forno&Lücking spec.nov.,C.arborescens Dal Forno,Chaves&Lücking

| 9 | A first assessment of Galapagos basidiolichens显示文摘As part of an ongoing comprehensive inventory of Galapagos lichens,a first assessment of the morphology and anatomy of basidiolichens from the archipelago is presented here.It is the basis for further studies of the taxonomy,ecology and biogeography of this poorly known group of lichens.Four genera,all in Hygrophoraceae,can be distinguished:Acantholichen,Cora,Cyphellostereum and Dictyonema.Both Acantholichen and Cora are characterized by chroococcoid cyanobionts and a heteromerous thallus with a distinct upper cortex and photobiont layer.The monotypic Acantholichen pannarioides is entirely composed of small,branched,inflated squamules that appear densely pruinose because their cortical hyphae bear characteristically swollen,densely spinose end cells(acanthohyphidia);this species has never been observed fertile.The common Cora glabrata is foliose,forming large,radially zonate,conch-like,often tiled thalli,when fertile with circular lines of basidiocarps on its lower side.Dictyonema is distinguished by filamentous cyanobionts and distinctly filamentous thalli that are homomereous(i.e.,not distinctly layered);all species of Dictyonema s.str.have trichomes(filamentose cyanobacterial photobionts)closely enveloped by fungal cells of a jigsaw pattern.In D.sericeum thallus filaments(i.e.,individual fibrils)aggregate to form shelf-like structures similar in appearance to polyporoid bracket fungi;basidiocarps develop in irregular patches on the lower side of these shelves.In contrast,fibrils of D.schenkianum grow encrusting their substrate with irregularly to suberect trichomes,occasionally bearing basidiocarps dispersed across the thallus.Two other species in Galapagos show adpressed growth form and are described here as new:Dictyonema pectinatum,which is characterized by large parallel fibrils with paler,papillate tips,and D.galapagoense,characterized by thin trichomes of more squarrish elongate cells.The genus Cyphellostereum is represented by two species:the newly described C.imperfectum and an unnamed Cyphellostereum sp.,both phenotypically similar to free-living cyanobacterial filaments.Cyphellostereum imperfectum has narrow photobiont filaments with irregular hyphal sheath leaving interspaces;macroscopically it shows a bluish green thallus with a distinct prothallus.Cyphellostereum sp.has a rather uncommon basidiolichen appearance:thin sctytonematoid fibrils surrounded by straight fungal cells forming shiny tufts.The new combination Cyphellostereum nitidum is also proposed.The ecology and taxonomy of Galapagos basidiolichens is briefly discussed and a key and short descriptions of all species are presented. | Alba Yánez Manuela Dal-Forno Frank Bungartz Robert Lücking James D.Lawrey | 2012 | Fungal Diversity2012，，1： | 0 |
| 10 | High levels of endemism among Galapagos basidiolichens显示文摘This study is a re-assessment of basidiolichen diversity in the Galapagos Islands.We present a molecular phylogenetic analysis,based on 92 specimens from Galapagos,using two nuclear ribosomal DNA markers(ITS and nuLSU).We also re-examined the morphology and anatomy of all sequenced material.The molecular results confirm our previous assessment that all Galapagos basidiolichens belong to the Dictyonema clade,which in Galapagos is represented by four genera:Acantholichen,Cora,Cyphellostereum,and Dictyonema.Most species previously reported from Galapagos in these genera were at the time believed to represent widely distributed taxa.This conclusion,however,has changed with the inclusion of molecular data.Although almost the same number of species is distinguished,the phylogenetic data now suggest that all are restricted to the Galapagos Islands.Among them,six species are proposed here as new to science,namely Cora galapagoensis,Cyphellostereum unoquinoum,Dictyonema barbatum,D.darwinianum,D.ramificans,and D.subobscuratum;and four species have already been described previously,namely Acantholichen galapagoensis,Cora santacruzensis,Dictyonema pectinatum,and D.galapagoense,here recombined as Cyphellostereum galapagoense.Our analysis is set on a very broad phylogenetic framework,which includes a large number of specimens(N=826)mainly from Central and South America,and therefore strongly suggests an unusually high level of endemism previously not recognized.This analysis also shows that the closest relatives of half of the basidiolichens now found in Galapagos are from mainland Ecuador,implying that they reached the islands through the shortest route,with all species arriving on the islands through independent colonization events. | Manuela Dal Forno Frank Bungartz Alba Yanez-Ayabaca Robert Lücking James D.Lawrey | 2017 | Fungal Diversity2017，，4： | 0 |
