Trilobites offer the opportunity to explore postembryonic development within the fossil record of arthropod evolution. In contrast to most trilobites, the Silurian proetid Aulacopleura konincki from the Czech Republic exhibits marked variation in the mature number of thoracic segments, with five morphs with 18-22 thoracic segments. The combination of abundant articulated specimens available fro...

The distinction and monophyletic property of the basidiomycetous yeast species in the Bulleribasidium clade of the order Tremellales was resolved by molecular phylogenetic analysis based on the combined sequences of the 18S rRNA gene, internal transcribed spacer (ITS) region including 5.8S rRNA gene and 26S rRNA gene D1/D2 domain. The addition to the clade of new anamorphic species identified a...

Many rust fungi (Uredinales) that infect rhododendrons are difficult to identify because of similar spore size and overall morphology. As part of a morphological study of rusts in the genus Chrysomyxa, herbarium specimens of Asian rhododendron rusts were examined by light and scanning electron microscopy. They were compared with similar taxa from Europe and North America. Revised and illustrate...

Abstract Eight new anamorphic species of Pucciniales belonging to the genera Aecidium, Caeoma, Malupa, Milesia, Physopella and Uredo are proposed. The were collected in Itatiaia National Park states Minas Gerais Rio de Janeiro, Brazil, on plant families Annonaceae, Apocynaceae, Euphorbiaceae, Menispermaceae, Salicaceae, Solanaceae Verbenaceae.

Abstract Chaetosphaeriaceae is one of the largest families in Sordariomycetes with its members commonly found on decaying leaf, fruit, branch, bark and wood both terrestrial submerged environment nature. This paper reports our research result diversity, taxonomy phylogeny anamorphic China, which based a systematic study an integrated approach morphological observation phylogenetic analysis for ...

Histoplasma capsulatum is a dimorphic fungal pathogen naturally found in the soil. Inhalation of conidia can result in pulmonary histoplasmosis and, in some cases, causes severe disseminated disease and death. This fungus is an ascomycete that has an anamorphic or asexual stage and a teleomorphic or sexual stage, known as Ajellomyces capsulatus, which results from (+) and (-) mating types. Sexu...

Gardens of fungus-growing ants (Formicidae: Attini) traditionally have been thought to be free of microbial parasites, with the fungal mutualist maintained in nearly pure "monocultures." We conducted extensive isolations of "alien" (nonmutualistic) fungi from ant gardens of a phylogenetically representative collection of attine ants. Contrary to the long-standing assumption that gardens are mai...
