A preliminary ITS phylogeny of Melanoleuca (Agaricales), with special reference to European taxa

Abstract

-Ninety-one Melanoleuca collections were chosen to test the agreement of current and traditional infrageneric tripartite classifications of Melanoleuca (subgenera Acystis without cystidia, Urticocystis with urticiform cystidia, and Melanoleuca with macrocystidia) with molecular phylogenetic data (ITS sequences analysis) and to evaluate the systematic significance of relevant morphological characters. Melanoleuca is found to be monophyletic, and only two emended subgenera, Urticocystis and Melanoleuca, are supported. Subg. Urticocystis comprises all taxa with urticoid cystidia plus the macrocystidiate M. cognata complex. The artificial subg. Acystis is shown to be polyphyletic and no longer tenable. The entire genus comprises at least 10 clades with 13 subclades. Melanoleuca sublanipes sp. nov. and new combinations M. exscissa f. iris, M. exscissa f. sarcophylla, M. exscissa f. diverticulata, and M. paedida f. electropoda are introduced.

Türkiye’deki Bazı Melanoleuca türlerinin (Fungi: Basidiomycota) Filogenisi ve Yeni bir Kayıt Olarak Melanoleuca angelesiana A.H. Sm. Türünün Tanımlanması

“…All collected samples were deposited in the Fungarium of Van Yüzüncü Yıl University (VANF). Specimens were photographed in situ, using with a Canon (EOS 60D) camera equipped with Tokina 100 mm macro lens Kastamonu Uni., Orman Fakültesi Dergisi, 2018, 18 ( (Murrill, 1913;Bresinsky and Stangl, 1977;Bon, 1991;Breitenbach and Kränzlin, 1991;Dähncke, 2004;Jordan, 2004;Gerault, 2005;Clémençon 2009;Vizzini et al, 2011;Buczacki, 2012;Garcia, Blanco & Matheney 2013;Kuo and Methven, 2014;Desjardin, Wood & Stevens, 2015).

“…The topologies of the MP and ML phylogenetic trees had no considerable differences, so only one tree (ML) was given to indicate phylogenetic relationships. Phylogenetic tree constructed based on ITS region (Figure 2) composed from two major clades which were named according to the study of Vizzini et al (2011) and called as clade A (subgenera Melanoleuca) and clade B (subgenera Urticocystis). Clade A and B were well supported with 99 and 98% bootstrap, respectively.…”

Taxonomy, ecology and distribution of Melanoleuca strictipes (Basidiomycota, Agaricales) in Europe.

“…For lamellae, L is the number of entire lamellae and l is the number of lamellulae tiers between each pair of entire lamellae. Characters of cheilocystidia are defined according to Vizzini et al (2011). P h y l o g e n e t i c a n a l y s i s. Maximum likelihood (ML) and Bayesian inference (BI) analyses were used to estimate phylogenetic relationships.…”

“…Moreover, numerous species described in history are difficult to define. According to Vizzini et al (2011), there are 332 validly published names (species and infraspecific taxa) in this genus, including 126 European and 206 extra-European taxa. However, most of these published names are treated as synonyms.…”

Melanoleuca Pseudoluscina – A Dune Species with an Interesting History

“…They advised that the taxon M. pseudoluscina Bon 1980 was later reduced to a variety of M. rasilis (Boekhout, 1988) but more recent DNA-based phylogenetic studies (Vizzini et al, 2011) Melanoleuca pseudoluscina -a dune species with an interesting history (coll. Henrici, A.…”
