Setomelanomma holmii (Pleosporales, Phaeosphaeriaceae) on living spruce twigs in Europe and North America

چکیده
Setomelanomma holmii M. Morelet, previously known only from the type specimen in France, was discovered in the U.S.A. (Kansas and Wisconsin) and Canada (Ontario) on living twigs of spruce (Picea pungens and Picea glauca). This fungus was grown from ascospores and compared with the ex-holotype culture. Morphology and ITS rDNA sequence similarities indicate that S. holmii belongs in the Pleosporales, Phaeosphaeriaceae. Sequence analysis of the SSU nrDNA places S. holmii in a clade containing members of the Leptosphaeriaceae and Phaeosphaeriaceae. Setomelanomma holmii is redescribed and illustrated based on the holotype and North American specimens.

Multi-locus phylogeny of Pleosporales: a taxonomic, ecological and evolutionary re-evaluation
Five loci, nucSSU, nucLSU rDNA, TEF1, RPB1 and RPB2, are used for analysing 129 pleosporalean taxa representing 59 genera and 15 families in the current classification of Pleosporales. The suborder Pleosporineae is emended to include four families, viz.Didymellaceae, Leptosphaeriaceae, Phaeosphaeriaceae and Pleosporaceae. In addition, two new families are introduced, i.e. Amniculicolaceae and L...
متن کاملNotes on some endophytic fungi isolated from Quercus brantii in Dena, Kohgiluyeh and Boyer-Ahmad province
In this study, we report some endophytic fungi isolated from twigs of Quercus brantii in Dena region of Kohgiluyeh and Boyer-Ahmad province. The twigs were sampled from trees which had basidiocarps of the invasive basidiomycetous polypore fungus Inonotus krawtzewii on their trunk. Altogether, ca. 40 pure isolates were obtained. The ITS sequences were obtained for 16 isolates, and their phylogen...

Portions of the mating type genes from Ophiosphaerella korrae (J. Walker & A.M. Smith) R.A. Shoemaker (= Leptosphaeria korrae J. Walker & A.M. Smith), a pathogenic fungus of grasses, were examined by PCR (polymerase chain reaction). For nine isolates of O. korrae from North America, both mating type genes were amplified, demonstrating that both MAT idiomorphs are detectable in this homothallic ...

The present paper represents the second contribution in the Genera of Fungi series, linking type species of fungal genera to their morphology and DNA sequence data, and where possible, ecology. This paper focuses on 12 genera of microfungi, 11 of which the type species are neo- or epitypified here: Allantophomopsis (A. cytisporea, Phacidiaceae, Phacidiales, Leotiomycetes), Latorua gen. nov. (La...
