Ectothiorhodospira halophila: A new species of the genus Ectothiorhodospira

Summary A halophilic purple sulfur spirillum, previously reported by the authors and called SL-1, has been characterized as a new species of the genus Ectothiorhodospira, E. halophila. The organism can grow in media containing from 9% NaCl to 30% NaCl. It needs no vitamins. Succinate or acetate can be used as hydrogen donors, but a reduced sulfur source is necessary for growth. The temperature optimum is 47°C. The cells are bipolarly flagellated, not monopolarly flagellated as previously reported.     

Three new species in the lichen genus Ionaspis

Ionaspis fuegensis, I. granvina and I. ventosa are described. The genus is recorded for the first time with certainty from the cool-temperate Southern Hemisphere. I. granvina differs from all other species in its carbonaceous black exciple and I. ventosa in its ecology: windswept mountain summits.     

Chrysocapsopsis rupicola: A new genus and species in the Chrysophyceae

Chrysocapsopsis rupicola gen. et sp. nov. (Chrysophyceae) is described. It differs from Chrysocapsa and the closely related genera Chrysocapselia and Tetrachrysis by possessing both epiphytic and planktonic forms within the same life-history. Reproduction is by budding which produces short irregular branches within a gelatinous mass. Four or more aplanospores are produced from each mother cell; no motile cells were observed.     

A new species of the genus Trematosphaeria from China

A new species of the genus Trematosphaeria was isolated and identified from the soil in Jiuzhaigou Nature Reserve, southwestern China. The new taxon was studied based on morphological characters and phylogenetic analyses of three nuclear loci, i.e., the internal transcribed spacer rDNA operon (ITS), and large and small subunit nuclear ribosomal DNA (nuc28S rDNA, nuc18S rDNA). The analyzed Trematosphaeria species were clustered in several clades within the Pleosporales and the genus was shown to be polyphyletic. The new species is introduced as Trematosphaeria terricola, and it is characterized by short-papillate ascomata with suborbicular ostiolum, 3-septate, cinnamon-brown, fusiform ascospores with narrowly rounded ends, verruculose at maturity. Trematosphaeria terricola is compared with morphologically similar species T. confusa, T. mangrovis, and T. pertusa, which differ from the former species in the number of septa, and the shape and size of the ascospores with or without a sheath. This is the first report of a Trematosphaeria isolate from alpine soil in China.     

Three new species of the genus Leveillula from Iran

 Based on molecular and morphological studies, Leveillula guilanensis sp. nov. on Chondrilla juncea, L. lactucae-serriolae sp. nov. on Lactuca serriola, and L. mindii sp. nov. on Mindium laevigatum are described from Iran.
