Tamhinispora saraburiensis sp. nov. was collected on decaying culms of bamboo in Saraburi Province, Thailand. Tamhinispora saraburiensis is characterized as dark brown to black, obpyriform, and dictyoseptate and has conidia with long appendages arising from the conidial tip. Phylogenetic analyses of the combined ITS and LSU rDNA sequence data demonstrated that this species formed distinctly from other species and that it belongs in the family Tubeufiaceae. Tamhinispora saraburiensis is therefore introduced here with a description, morphological illustrations and molecular data. A key to the species of Tamhinispora is provided.

Clinoconidium lauracearum sp. nov. (Cryptobasidiaceae) is described and illustrated from infected fruits of Cinnamomum tamala (Lauraceae) collected from Rudraprayag district of Uttarakhand State, India. The species shows characteristics of Clinoconidium and Drepanoconis, but differs from other species in these genera by the combination of shapes, sizes, and septation of basidiospores. Molecular data also indicate that the present taxon is distinct from the other known species of Clinoconidium and Drepanoconis. Analyses of combined ITS and LSU rDNA and separate LSU rDNA sequence data reveal a close association of the present taxon to the genus Clinoconidium, but also that it is distinct from the other known species in the genus.

Molecular Phylogenetic

Based on DNA sequence data, the genus Leptosillia is shown to belong to the Xylariales. Molecular phylogenetic analyses of ITS-LSU rDNA sequence data and of a combined matrix of SSU-ITS-LSU rDNA, rpb1, rpb2, tef1 and tub2 reveal that the genera Cresporhaphis and Liberomyces are congeneric with Leptosillia. Coelosphaeria fusariospora, Leptorhaphis acerina, Leptorhaphis quercus f. macrospora, Leptorhaphis pinicola, Leptorhaphis wienkampii, Liberomyces pistaciae, Sphaeria muelleri and Zignoëlla slaptonensis are combined in Leptosillia, and all of these taxa except for C. fusariospora, L. pinicola and L. pistaciae are epitypified. Coelosphaeria fusariospora and Cresporhaphis rhoina are lectotypified. Liberomyces macrosporus and L. saliciphilus, which were isolated as phloem and sapwood endophytes, are shown to be synonyms of Leptosillia macrospora and L. wienkampii, respectively. All species formerly placed in Cresporhaphis that are now transferred to Leptosillia are revealed to be non-lichenized. Based on morphology and ecology, Cresporhaphis chibaensis is synonymised with Rhaphidicyrtis trichosporella, and C. rhoina is considered to be unrelated to the genus Leptosillia, but its generic affinities cannot be resolved in lack of DNA sequence data. Phylogenetic analyses place Leptosillia as sister taxon to Delonicicolaceae, and based on morphological and ecological differences, the new family Leptosilliaceae is established. Furfurella, a new genus with the three new species, F. luteostiolata, F. nigrescens and F. stromatica, growing on dead branches of mediterranean fabaceous shrubs from tribe Genisteae, is revealed to be the closest relative of Delonicicola in the family Delonicicolaceae, which is emended. ITS rDNA sequence data retrieved from GenBank demonstrate that the Leptosilliaceae were frequently isolated or sequenced as endophytes from temperate to tropical regions, and show that the genus Leptosillia represents a widely distributed component of endophyte communities of woody plants.

A new species of a hyphomycetous fungus, Hermatomyces trangensis, was collected during an investigation of the diversity of palm fungi in Na Yong district, Trang province, Southern Thailand, and is introduced in this paper based on morphological and molecular evidence. The fungus is characterized by the production of only one type of conidia, globose or subglobose in front view, broadly ellipsoidal or oblong in lateral view, with dark brown to black central cells and subhyaline to pale brown peripheral cells and sporulation in culture. Phylogenetic analyses of combined SSU rDNA, LSU rDNA, ITS rDNA, TEF1 and RPB2 sequence data using maximum parsimony, maximum likelihood and Bayesian inference approaches placed the fungus within a strongly supported clade with other Hermatomyces species within the family Hermatomycetaceae (Pleosporales, Dothideomycetes). Morphologically, it is similar to other taxa with only one type of conidia such as H. sphaericus, H. sphaericoides and H. verrucosus but molecular data clearly support H. trangensis as distinct from those species.

Abstract Background Heterotrichous ciliates are common members of microeukaryote communities which play important roles in both the transfer of material and the flow of energy in aquatic food webs. This group has been known for over two centuries due to their large body size and cosmopolitan distribution. Nevertheless, species identification and phylogenetic relationships of heterotrichs remain challenging due to the lack of accurate morphological information and insufficient molecular data. Results The morphology and phylogeny of two heterotrichous ciliates, namely Gruberia foissneri spec. nov. and Linostomella vorticella (Ehrenberg, 1833) Aescht in Foissner et al., 1999, were studied using rigorous methods (living morphology, stained preparations, and small subunit rDNA sequence data). Gruberia foissneri spec. nov. is morphologically very similar to G. uninucleata Kahl, 1932, however, it can be distinguished from the latter by having more ciliary rows (about 32 vs. about 20) and macronuclear shape (sausage-shaped vs. ellipsoid). Based on a combination of previous and present studies, an improved diagnosis of L. vorticella is supplied and several taxonomic anomalies are clarified. In addition, phylogenetic analyses based on SSU rDNA sequence data support the generic assignment of these two species. Conclusions Modern ciliate taxonomy should be performed by means of detailed living observation, stained preparations and molecular information. For those species that have been reported in previous studies, it is necessary to provide as much useful information as possible using state-of-the-art methods in order to resolve taxonomic anomalies.

Nevertheless, species identification and phylogenetic relationships of heterotrichs remain challenging due to the lack of accurate morphological information and insufficient molecular data. Results The morphology and phylogeny of two poorly known heterotrichous ciliates, Gruberia uninucleata Kahl, 1932 and Linostomella vorticella (Ehrenberg, 1833) Aescht in Foissner et al. , 1999, were investigated based on their living morphology, infraciliature, and small subunit (SSU) rDNA sequence data. Based on a combination of previous and present studies, detailed morphometric data and the improved diagnoses of both species are supplied here. In addition, molecular data of the two species are reported for the first time. Phylogenetic analyses based on SSU rDNA sequence data support the generic assignment of these two species. Conclusions Two insufficiently studied species, G. uninucleata and L. vorticella , are redefined using state-of-the-art methods. Previous reports on these two species are re-evaluated in the light of present findings.

A new species of Lolia and the sexual morph of L. aquatica are described, with illustrations, from decayed submerged wood in the River Nile, Egypt. Molecular phylogenetic analyses of partial SSU and LSU rDNA sequence data place the sexual morph of L. aquatica and the new species, L. dictyospora in a monophyletic clade, distant from the closely related fungi in the freshwater family Lindgomycetaceae. Pairwise LSU rDNA sequence alignment of the sexual/asexual morphs of L. aquatica are 99% similar. Lolia species are characterized by pseudothecial or stromatic, immersed to erumpent, dark-brown to black, coriaceous to sub-carbonaceous ascomata, cylindric-clavate, bitunicate, fissitunicate, short pedicellate asci, yellow to reddish-brown, phragmo- or dictyospores, surrounded by prominent gelatinous sheath. Lolia species are phylogenetically distant from the closely related genera: Leptosphaeria (Leptosphaeriaceae) and Massariosphaeria (Pleosporales incert. sed.). Lolia differs from Leptosphaeria in having a prominent large gelatinous ascospore sheath, while this is absent in Leptosphaeria species. Lolia differs from Massariosphaeria in having smaller ascospores and fewer transverse septa. Based on molecular data and morphology, a new species, Lolia dictyospora, is established.

The morphology and morphogenesis of Pseudosincirra longicirrata nov. gen. and nov. comb., isolated from southern China, were investigated with living observation and protargol staining. Our population is similar to the original population in living characteristics and ciliary patterns. The main determinable morphogenetic features of P. longicirrata nov. comb. are the presence of five frontoventral-transverse cirral anlagen (FVT-anlagen) and a dorsomarginal kinety anlage. According to the origin of FVT-anlagen IV and V in proter, it can be determined that P. longicirrata nov. comb. possesses two frontoventral rows and one right marginal row. Hence, a new genus, Pseudosincirra nov. gen., is proposed, and the diagnosis of P. longicirrata nov. comb. is improved. The new genus is diagnosed as follows: adoral zone of membranelles and undulating membranes is in a Gonostomum pattern; there are three enlarged frontal cirri, one buccal cirrus, and one parabuccal cirrus; postperistomial cirrus and transverse cirri are lacking; there are two more or less long frontoventral rows and one right and two or more left marginal rows; cirri within all rows very widely spaced; dorsal kinety pattern is of Urosomoida type, that is, three dorsal kineties and one dorsomarginal kinety; and caudal cirri are present. Phylogenetic analyses based on the small subunit ribosomal (SSU rDNA) sequence data indicate that P. longicirrata nov. comb. clusters with Deviata and Perisincirra. It is considered that Pseudosincirra nov. gen. and Perisincirra paucicirrata should be assigned to the family Deviatidae; fine cirri, and cirri within all rows being relatively widely spaced, should be considered as plesiomorphies of Deviatidae; and Deviatidae is closely related to Dorsomarginalia or Strongylidium–Hemiamphisiella–Pseudouroleptus.
