Genetic variation and natural hybridization betweenOrchis laxiflora andOrchis palustris (Orchidaceae)
The data indicate that hybrids are only partially fertile, with a very limited mixing up of the two parental gene pools; this is shown by the lack of significant lowering of genetic distances when sympatric and allopatric heterospecific samples are compared. Expand
Molecular analysis reveals two new dimorphic species of Hesperomyces (Ascomycota, Laboulbeniomycetes) parasitic on the ladybird Coleomegilla maculata (Coleoptera, Coccinellidae).
Four morphotypes of Hesperomyces found on the ladybird Coleomegilla maculata belong to two phylogenetic species, each with a pair of morphotypes displaying position specificity, confirming of dimorphism in Laboulbeniales. Expand
A new species of Stigmatomyces from Baltic amber, the first fossil record of Laboulbeniomycetes.
A fossil ascomycete was found attached to the thorax of a stalk eyed fly (Diopsidae: Prosphyracephala succini) in a fragment of Baltic amber, which constitutes the oldest record of a parasitic fungus on an insect. Expand

  • 1 January 2011
Laboulbenia barraganii is the first of the Laboulbeniales to be reported on beetles of the family Salpingidae, and L. biformis displays a moderate dimorphism associated with the position on the host insect. Expand
Preserving accuracy in GenBank
GenBank, the public repository for nucleotide and protein sequences, is a critical resource for molecular biology, evolutionary biology, and ecology. While some attention has been drawn to sequenceExpand
Fungal diversity notes 1036–1150: taxonomic and phylogenetic contributions on genera and species of fungal taxa
The present study describes one new family (Pseudoberkleasmiaceae in Dothideomycetes), five new genera (Caatingomyces, Cryptoschizotrema, Neoacladium, Paramassaria and Trochilispora), 71 new species and twelve new combinations. Expand
Orchis longicornu Poiret in Sardinia: genetic, morphological and chorological data
The genetic analysis of 27 enzyme loci in population samples from locations where both species had been recorded showed that in the population samplesFrom Sardinia the polymorphic loci are in Hardy-Weinberg equilibrium. Expand
Molecular evidence for allopolyploid speciation and a single origin of the western Mediterranean orchid Dactylorhiza insularis (Orchidaceae)
The hybrid origin of the western Mediterranean orchid Dactylorhiza insularis was demonstrated by genetic markers, and available data agree with a single origin for D.insularis, which possibly occurred in the present postglacial when D. romana and D. sambucina, expanding from their glacial refugia, came into contact.

Gene variation and gene flow inOrchis morio (Orchidaceae) from Italy
Data are presented on genetic variation at 27 enzyme loci of the Green-Winged orchid,Orchis morio, in 18 population samples from Italy. The existence in Italy of two subspecies, i.e. subspp.morioExpand
Genetic variation inOrchis papilionacea (Orchidaceae) from the Central Mediterranean region: Taxonomic inferences at the intraspecific level
Papilionacea, grandiflora, andheroica are, at least in the study area, not to be considered as subspecies, but as simple morphs, controlled by few genes (possibly two) with Mendelian inheritance. Expand
