The genus Relicinopsis is nested within Relicina (Parmeliaceae, Ascomycota)

AbstractMacro-morphological features traditionally used to segregate genera in Parmeliaceae have been shown to be highly plastic, placing limits on their taxonomic value. Here we aim to elucidate the evolutionary relationships of the genera Relicina and Relicinopsis and reassess the phenotypic features traditionally used to separate these genera. To this end, we gathered ribosomal DNA sequences of ITS, nuLSU and mtSSU and analyzed them in a phylogenetic framework. Relicina was recovered as paraphyletic, with Relicinopsis nested within, and three different clades were identified within Relicina. Alternative hypothesis tests significantly rejected the monophyly of Relicina. Our results indicate that the presence or absence of bulbate cilia is of limited taxonomic value in this clade. Based on differences in conidia, however, we propose to accept Relicinopsis as a subgenus within Relicina as Relicina subgen. Relicinopsis (Elix & Verdon) Kirika, Divakar & Lumbsch. It is proposed that five new combinations of species previously classified in Relicinopsis be placed in Relicina.

Clade 1

Many phenotypical features traditionally used to classify genera in Parmeliaceae and in lichens in general have evolved several times independently, potentially limiting their taxonomic utility. Here, we aim to elucidate evolutionary relationships of Canoparmelia s. lat. among other parmotremoid taxa. A multilocus dataset (ITS, nuLSU and mtSSU rDNA sequences) was gathered and analyzed within a phylogenetic framework. Canoparmelia s. lat. was recovered as highly polyphyletic within the parmelioid clade, and three divergent lineages representing Canoparmelia s. lat. were identified in addition to the previously segregated Crespoa group. Of these, two formed a sister relationship with Parmotrema. However, no apparent diagnostic morphological features were found distinguishing the distinct Canoparmelia s. lat. clades reconstructed in the phylogenetic analyses. As a consequence, we propose to restrict the circumscription of Canoparmelia to clade 1 (i.e. the C. texana group) and to include clades 2 and 3 in Parmotrema. We propose to recognize these well-supported monophyletic clades at subgeneric level. Consequently, the new subgeneric name Parmotrema subgen. Africanae is proposed for clade 3 recovered in this study. Since clade 4, which clusters with the genera Nesolechia and Punctelia, is only represented by a single sequenced specimen, we refrain from proposing any taxonomic changes. The new combinations Parmotrema epileucum, and P. zimbabwense are proposed.

Boletus peckii, B. pulchriceps and B. roseopurpureus, which were originally described from North America, are characterized by a yellow tube layer that often bruises blue, a yellow reticulated stipe especially at the apex, firm yellow-tinged flesh that often turns blue when exposed, smooth spores and an interwoven trichodermic pileipellis. The phylogenetic positions of the three species are inferred by molecular phylogenetic analysis based on DNA sequences of four gene markers (ITS, nrLSU, tef1-α and rpb1). Both morphological features and molecular phylogenetic evidence indicate that these three boletes belong to Butyriboletus, and thus, should be transferred to the genus.

Informal Groups

Mitochondrial small subunit (mtSSU) rDNA sequences elucidated phylogenetic relationships in Neonectria Wollenw. (anamorphs = Cylindrocarpon Wollenw.; Ascomycetes, Hypocreales). Twelve isolates representing seven species in five taxonomically informal groups of Neonectria were subjected to phylogenetic analysis. Fusarium inflexum R. Schneid. (teleomorph: Gibberella) and Nectria cinnabarina (Fr.) Fr. (= Nectria s.str.) were outgroups. All of the Neonectria species formed a strongly supported clade with respect to the outgroups, indicating a single ascomycete genus for the holomorphs of Cylindrocarpon. Within the Neonectria clade there were three well-supported subclades that only partially corresponded to phenotype-defined groups. DNA sequence divergence among the twelve Neonectria isolates, 2.3-7.4%, was sufficient to resolve them. The results suggest that the mtSSU rDNA region is appropriate for phylogenetic analysis of Neonectria and Cylindrocarpon. The following new combinations are proposed: Neonectria coronata, Neonectria discophora, Neonectria neomacrospora, Neonectria radicicola, Neonectria rugulosa, Neonectria veuillotiana.Key words: Ascomycetes, Hypocreales, Nectria, systematics, tree pathogens.

Abstract:A phylogenetic study using DNA sequences of the nuclear ribosomal large subunit from 38 species is used to infer the phylogeny of species currently placed in Topeliopsis. The genus is shown to be polyphyletic; monophyly of previous and current circumscriptions of the genus are rejected using two alternative hypothesis tests. Topeliopsis meridiensis is shown to be closer to Chapsa than Topeliopsis, but additional studies are necessary to understand the circumscription of Chapsa. The new genus Melanotopelia Lumbsch & Mangold is described to accommodate T. toensbergii and T. rugosa. These species were previously regarded as aberrant in Topeliopsis because of their thin-walled ascospores and dark pigmented proper exciple. The new combination Graphis mexicana (Hale) Kalb, Lücking & Lumbsch is proposed and Graphis muscicola and Topeliopsis globosa reduced to synonymy with this species.
