Polyporus dictyopus, with a large number of heterotypic synonyms, has been traditionally considered a species complex, characterized by wide morphological variation and geographic distribution. Thus, neotropical specimens previously identified as P. dictyopus from Amazonia, Cerrado and Atlantic Forest biomes were studied based on detailed macro- and micromorphological examination and phylogenet...

During mycological surveys of different areas Punjab, Pakistan, we collected a new species from the genus Candolleomyces. This is first report any this Pakistan. Candolleomyces asiaticus M.Asif, A.Izhar, Niazi & Khalid sp. nov. characterized by ellipsoid to oblong-ellipsoid (8.2 × 5 µm) basidiospores with indistinct germ pores, lageniform utriform cheilocystidia without adhering deposit...

We studied the bee specialist fungus Ascosphaera in wild solitary bees to investigate the diversity of the genus in nature and the ecology of these fungi with their bee hosts. A new morphologically distinctive species was discovered which also has a unique nrITS sequence. This new species, here named Ascosphaera callicarpa, is common on the larval feces of the solitary bee Chelostoma florisomne...

background carbapenemes are a good choice for treatment of infections caused by multidrug resistant pseudomonads aeruginosa. the emergence of carbapenem resistance has become a major problem in treatment of this organism especially among immunocompromised patients including burn patients. objectives the aim of this study was to investigate carbapenem-resistance mechanisms among burn patients in...

Symbiotic fungi living in plants as endophytes, and in lichens as endolichenic fungi, cause no apparent symptoms to their hosts. They are ubiquitous, ecologically important, hyperdiverse, and represent a rich source of secondary compounds for new pharmaceutical and biocontrol products. Due in part to the lack of visible reproductive structures and other distinctive phenotypic traits for many sp...

BACKGROUND The fixed genetic differences between ecologically divergent species were found to change greatly depending on the markers examined. With such species it is difficult to differentiate between shared ancestral polymorphisms and past introgressions between the diverging species. In order to disentangle these possibilities and provide a further case for DNA barcoding of plants, we exami...
