A multi-gene phylogeny of Lactifluus (Basidiomycota, Russulales) translated into a new infrageneric classification of the genus Naturalis
Crop, E. de; Nuytinck, J.; Putte, K. van de; Wisitrassameewong, K.; Hackel, J.; Stubbe, D.; Hyde, K.D.; Roy, M.; Halling, R.E.; Moreau, P.-A.; Eberhardt, U.; Verbeken, A..
Infrageneric relations of the genetically diverse milkcap genus Lactifluus (Russulales, Basidiomycota) are poorly known. Currently used classification systems still largely reflect the traditional, mainly morphological, characters used for infrageneric delimitations of milkcaps. Increased sampling, combined with small-scale molecular studies, show that this genus is underexplored and in need of revision. For this study, we assembled an extensive dataset of the genus Lactifluus, comprising 80 % of all known species and 30 % of the type collections. To unravel the infrageneric relationships within this genus, we combined a multi-gene molecular phylogeny, based on nuclear ITS, LSU, RPB2 and RPB1, with a morphological study, focussing on five important...

"Decrypting the Hebeloma crustuliniforme complex: European species of Hebeloma section Denudata subsection Denudata (Agaricales) " Naturalis
Eberhardt, U.; Beker, H.J.; Vesterholt, J..
Hebeloma subsection Denudata includes the type of H. section Denudata, Hebeloma crustuliniforme, as well as the majority of the taxa commonly included in the Hebeloma crustuliniforme complex. Complementing the work of D.K. Aanen and co-workers, and using refined morphological and molecular methods we were able to recognize further individual taxa within the section. Fifteen species occurring in Europe are assigned to H. subsect. Denudata. Of these, we describe eight species as new, namely H. aanenii, H. aurantioumbrinum, H. geminatum, H. louiseae, H. luteicystidiatum, H. pallidolabiatum, H. perexiguum and H. salicicola. Naucoria bellotiana, a species very similar to H. alpinum is recombined into Hebeloma. A key to Hebeloma subsect. Denudata is provided. We...

One fungus, which genes? Development and assessment of universal primers for potential secondary fungal DNA barcodes Naturalis
Stielow, J.B.; Lévesque, C.A.; Seifert, K.A.; Meyer, W.; Irinyi, L.; Smits, D.; Renfurm, R.; Verkley, G.J.M.; Groenewald, M.; Chaduli, D.; Lomascolo, A.; Welti, S.; Lesage-Meessen, L.; Favel, A.; Al-Hatmi, A.M.S.; Damm, U.; Yilmaz, N.; Houbraken, J.; Lombard, L.; Quaedvlieg, W.; Binder, M.; Vaas, L.A.I.; Vu, D.; Yurkov, A.; Begerow, D.; Roehl, O.; Guerreiro, M.; Fonseca, A.; Samerpitak, K.; Diepeningen, A.D. van; Dolatabadi, S.; Moreno, L.F.; Casaregola, S.; Mallet, S.; Jacques, N.; Roscini, L.; Egidi, E.; Bizet, C.; Garcia-Hermoso, D.; Martin, M.P.; Deng, S.; Groenewald, J.Z.; Boekhout, T.; Beer, Z.W. de; Barnes, I.; Duong, T.A.; Wingfield, M.J.; Hoog, G.S. de; Crous, P.W.; Lewis, C.T.; Hambleton, S.; Moussa, T.A.A.; Al-Zahrani, H.S.; Almaghrabi, O.A.; Louis-Seize, G.; Assabgui, R.; McCormick, W.; Omer, G.; Dukik, K.; Cardinali, G.; Eberhardt, U.; Vries, M. de; Robert, V..
The aim of this study was to assess potential candidate gene regions and corresponding universal primer pairs as secondary DNA barcodes for the fungal kingdom, additional to ITS rDNA as primary barcode. Amplification efficiencies of 14 (partially) universal primer pairs targeting eight genetic markers were tested across > 1 500 species (1 931 strains or specimens) and the outcomes of almost twenty thousand (19 577) polymerase chain reactions were evaluated. We tested several well-known primer pairs that amplify: i) sections of the nuclear ribosomal RNA gene large subunit (D1–D2 domains of 26/28S); ii) the complete internal transcribed spacer region (ITS1/2); iii) partial β-tubulin II (TUB2); iv) γ-actin (ACT); v) translation elongation factor 1-α (TEF1α);...

Tales of the unexpected: angiocarpous representatives of the Russulaceae in tropical South East Asia Naturalis
Verbeken, A.; Stubbe, D.; Putte, K. van de; Eberhardt, U.; Nuytinck, J..
Six new sequestrate Lactarius species are described from tropical forests in South East Asia. Extensive macro- and microscopical descriptions and illustrations of the main anatomical features are provided. Similarities with other sequestrate Russulales and their phylogenetic relationships are discussed. The placement of the species within Lactarius and its subgenera is confirmed by a molecular phylogeny based on ITS, LSU and rpb2 markers. A species key of the new taxa, including five other known angiocarpous species from South East Asia reported to exude milk, is given. The diversity of angiocarpous fungi in tropical areas is considered underestimated and driving evolutionary forces towards gasteromycetization are probably more diverse than generally...
