This paper describes a new species and gives a new record and a re-description of a known species of Trischistoma Cobb, 1913. Trischistoma taiguensis sp. nov. is characterized by having one pair of caudal setae on the tail; female body length of 562-699 µm, a = 35-42, b = 4.1-4.7, c = 11-14, c' = 3.9-4.6 and V = 79-82%. For the first time, Trischistoma pellucidum Cobb, 1913 is recorded from Sha...

Conlarium duplumascospora gen. et. sp. nov. and Jobellisia guangdongensis sp. nov. are described and illustrated from submerged wood collected from Guangdong Province, China. Conlarium duplumascospora is characterized by gregarious, coriaceous and beaked ascomata; cylindrical, unitunicate asci with a bipartite apical ring; biseriate, fusiform, hyaline, 0-5-septate ascospores with or without app...

We analyzed small subunit ribosomal DNA (ssu-rDNA) sequences to evaluate both the monophyly of the ciliate class Phyllopharyngea de Puytorac et al. (1974), and relationships among subclasses. Classifications based on morphology and ultrastructure divide the Phyllopharyngea into four subclasses, the Phyllopharyngia, Chonotrichia, Rhynchodia, and Suctoria. Our analyses of ssu-rDNA genealogies der...

Many descriptions of yeast species are based on a limited number of strains collected at one time from a single locale. Often, little is known of phenotypic or genotypic variation and covariation within species. We compare 36 strains of an asexual cactophilic yeast, Candida sonorensis, collected from Opuntia cacti. Comparisons were based on geographical distances between collection locales, res...

Dinoflagellates are an intriguing group of eukaryotes, showing many unusual morphological and genetic features. Some groups of dinoflagellates are morphologically highly uniform, despite indications of genetic diversity. The species Amphidinium carterae is abundant and cosmopolitan in marine environments, grows easily in culture, and has therefore been used as a 'model' dinoflagellate in resear...

Species of Colletotrichum cause diseases on a wide range of hosts, frequently infecting plants in the Agavaceae (monocotyledons: Liliales). Three species of Colletotrichum restricted to the Agavaceae were detected through morphological studies of specimens and molecular sequence analyses of the LSU of the nu-rDNA and the ITS region of the nu-rDNA from cultures. Colletotrichum agaves on Agave is...

Heterocephalacria bachmannii is a lichenicolous fungus that takes as hosts numerous lichen species of the genus Cladonia. In the present study we analyze whether the geographical distance, the host species or the host secondary metabolites determine the genetic structure of this parasite. To address the question, populations mainly from the Southern Europe, Southern Finland and the Azores were ...

A new species of the genus Synoecnema-S. watinagii sp. n.-is described and illustrated. The species is characterized by its small size, lack of sexual dimorphism apart from sexual characters, males with pericloacal disk, females with anterior vulva position and lacking an anus, and similar caudal organs in both sexes in the shape of long, deep slits on the surface of the posterior half of body....

Angelina rufescens is placed within the core clade of Rhytismatales (Leotiomycetes, Pezizomycotina, Ascomycota) based on analysis of LSU and mtSSU rDNA. The only species in the genus, it produces distinctive ascomata that reoccur annually on wood and on the remains of its own previous fructifications, forming dense conglomerations of interlocking longitudinally elongated apothecia with gray hym...
