The medullosans represent a diverse group of pteridosperms that was widely distributed in forested landscapes of the late Paleozoic. These plants became widely known from the extensive tropical lowland basins of Euramerica, where they grew as slender plants with large fronds and fern-like foliage. Besides, there also exist medullosans of Late Penns...

New Zealand’s diplodactylid geckos exhibit high species-level diversity, largely independent of discernible osteological changes. Consequently, systematic affinities of isolated skeletal elements (fossils) are primarily determined by comparisons of size, particularly in the identification of Hoplodactylus duvaucelii, New Zealand’s largest extant ge...

BackgroundIn zoology, species descriptions conventionally rely on invasive morphological techniques, frequently leading to damage of the specimens and thus only a partial understanding of their structural complexity. More recently, non-destructive imaging techniques have successfully been used to describe smaller fauna, but this approach has so far...

BackgroundBarbels are ray finned cyprinid fishes of the Old-World with partially unresolved, intricate taxonomy. Within the Barbus sensu lato paraphyletic assemblage, Barbus sensu stricto is a monophyletic tetraploid lineage of Europe, northern Africa and Middle East, including two monophyletic sibling genera: Barbus and Luciobarbus. Italy, Sloveni...

The genus Agaricus currently includes about 500 species in seven subgenera. Continuing an inventory of species in the Caribbean, this manuscript’s objective was to focus on those in Agaricus subg. Spissicaules. This subgenus has been recently proposed and divided into four sections by applying a new taxonomic system in which supraspecific taxa are ...

During investigation of pathogenic Alternaria in China, nine Alternaria isolates were obtained from two Caryophyllaceae plants. Based on morphological and multilocus phylogenetic approaches and pathogenicity tests, three pathogenic species of Alternaria including two new species and a new record in China were identified. Phylogenetically, the prese...

Laccaria fagacicola and L. pallidorosea, two new species collected from subtropical broad-leaved forests, were described in this study with both molecular and morphological evidence. Laccaria fagacicola is characterized by its brownish orange basidioma and globose to subglobose, echinulate basidiospores with spines 1–2 μm long and 1–1.5 μm wide at ...

The identity of Achroomyces effusus is re-established with the use of morphological and DNA methods, and a neotype is selected. The species is conspecific with Colacogloea peniophorae, the generic type of Colacogloea, and has a priority over it. A new combination, C. effusa, is proposed.

To explore species diversity of the genus Pseudocosmospora, collections from Beijing and Hubei Province of China were examined, and three undescribed species were encountered. Morphological features and DNA sequence analyses of the ITS, nc LSU rDNA, RPB1, and TUB regions support their placement in Pseudocosmospora and recognition of two new species...

During a diversity study of entomopathogenic fungi in an agricultural ecosystem, two fungi were collected, isolated, and identified based on molecular phylogenetic analyses of three nuclear loci (LSU, TEF1, and RPB1) combined with morphological data. In this study, one novel species is described, Ophiocordyceps flavida, and a new record of Pseudogi...
