To resolve the polyphyletic nature of Solenopeziaceae as it was originally circumscribed, we establish a new family Tricladiaceae for those genera originally placed in Solenopeziaceae that have aquatic hyphomycetelike asexual morphs and/or a sexual morph with glabrous apothecia. These include Cudoniella, Geniculospora, Graddonia, Halenospora, Mycofalcella, Spirosphaera, and Tricladium. Solenopeziaceae is confined to the genera Lasiobelonium, Solenopezia, Trichopeziza, and Trichopezizella, all of which have a sexual morph having apothecia with smooth-walled hairs. This taxonomy is supported by a multi-gene analysis using up to 15 genes, with a few of the taxa placed on the basis of a separate ITS phylogeny. Tricladiaceae forms a monophyletic clade with a basal sister relationship to Pleuroascaceae plus Helotiaceae; Solenopeziaceae forms a monophyletic clade with a basal sister relationship to Lachnaceae.

A New Species

In this paper, we report a new asexual-morph taxon belonging to the family Cordycipitaceae (Hypocreales), which is associated with a sexual morph of an ophioceras-like taxon on submerged wood collected from Baoshan, Yunnan, China. Morphologically, this new taxon is similar to known asexual morphs of Lecanicillium and characterized by conidiophores arising from hyaline hyphae, with gregarious, ellipsoid to ovoid, aseptate conidia. Phylogenetic analyses of a combined LSU, SSU, tef1-α and ITS sequence dataset positions our taxon in Cordycipitaceae and close to Lecanicillium sp. (CBS 639.85) and L. primulinum. Lecanicillium subprimulinum is introduced as a new species with support from molecular data.

Among Opiliones, Afrotropical lineages constitute some of the least studied groups in comparison with those endemic to other biogeographic provinces. Based upon morphological evidence, we erect Pyramidopidae, fam. nov. to distinguish a group of Laniatores from the family Phalangodidae. We review evidence from recent molecular phylogenetic studies that corroborate the independence of Pyramidopidae, fam. nov. from previously described families and support its sister relationship to another largely Afrotropical group, the family Assamiidae. The monotypic genus Maiorerus Rambla, 1993 is transferred to Pyramidopidae, fam. nov. The new family comprises 12 genera geographically restricted to Africa and the adjacent Canary Islands. Interfamilial relationships of the derived Laniatores are discussed in the context of gross and genitalic morphology.

A New Species

Alternaria section Panax currently includes seven species which are characterized by simple or branched and short to moderately long primary conidiophores as well as by solitary to short simple or branched chains of conidia with moderate to relatively long secondary conidiophores. Two species within the section have been reported to have sexual morphs. During the study of fungi on overwintered stems of Serratula coriacea Fisch. & C.A.Mey. (Asteraceae) from different regions of Urmia, West Azarbaijan Province, Iran, 26 isolates (16 from conidia and 10 from single ascospores) representing Alternaria characteristics were isolated and studied taxonomically. All the studied isolates formed sexual morph on PDA, PCA, V8–A, and HA media after 2 months incubation in the dark at 4 ºC and fully matured after 3 months. Based on morphological characteristics of sexual and asexual morphs and multiple gene sequences analyses (ITS-rDNA, GAPDH, RPB2 and TEF), the newly studied isolates represented a new species in Alternaria section Panax, which is described and illustrated here as Alternaria hedjaroudei. Alternaria hedjaroudei is phylogenetically close to A. avenicola, A. calycipyricola and A. photistica but it can be distinguished morphologically based on the formation of short chains of conidia (2–3 in a chain), absence of chlamydospores, smaller conidia size, relatively short secondary conidiophores, and fewer transverse septa in mature ascospores. Detailed morphological comparisons with other species in the section Panax are provided.

Three New Species

Peyssonneliaceae represents a monophyletic clade of red encrusting algae classified Peyssonneliales. Molecular analyses have been important for revealing unknown diversity in this family, which includes small, cryptic organisms, frequently distinguished solely by discrete anatomical characters. Brazil however, remains virtually unknown. To assess this diversity, phylogenetic and barcoding analyses using rbcL, COI-5P and SSU data, as well as morpho-anatomical analyses were performed. Here we report the first occurrence of two genera on the Brazilian coast: Ramicrusta and Incendia, and describe three new species: Ramicrusta fujiiana sp. nov., Ramicrusta paradoxa sp. nov. and Incendia yoneshigueana sp. nov. Ramicrusta was resolved as a monophyletic clade in the three reconstructed phylogenies, and had congruent topologies. In the rbcL phylogeny, Ramicrusta fujiiana formed a well-supported clade sister to a well-supported clade including R. aranea (Vanuatu, type locality) and R. textilis (Jamaica, type locality). Morphological characters of R. paradoxa are not in agreement with the original description of the genus. Therefore, we present an updated and broader concept of Ramicrusta. Incendia was resolved as a monophyletic clade with full support for rbcL. Incendia yoneshigueana is in a sister relationship with I. glabra (Vanuatu, type locality). This study extends the distributions of Ramicrusta and Incendia, proposes three new species, and confirms the effectiveness of rbcL, COI-5P and SSU in inferring phylogenetic relationships and delimiting species in the Peyssonneliales. The integrative approach established clear taxonomic concepts for the studied genera and species, and identified useful characters for genera delimitation in Peyssonneliaceae.

Diaporthe forlicesenica nom. nov. is proposed for D. dorycnii Dissan., Camporesi & K.D. Hyde, a later homonym of D. dorycnii (Mont.) Sacc. Diaporthe forlicesenica as well as the species D. goulteri have so far only been described in their asexual morphs. In this study, the sexual morphs for these species are recovered for the first time, from the dead branches of Cytisus sp. in Italy and from an unknown host in Thailand. The asexual-sexual morph connections of the species are confirmed by DNA sequence based phylogenetic analyses including the ITS, tef1, tub2 and his loci, supported by morphology. Detailed descriptions, illustrations and molecular data for the taxa are provided.

Abstract Four new Keratinophyton species (Ascomycota, Pezizomycotina, Onygenales), K. gollerae, K. lemmensii, K. straussii and K. wagneri, isolated from soil samples originating from Europe (Austria, Italy and Slovakia) are described and illustrated. The new taxa are well supported by phylogenetic analysis of the internal transcribed spacer region (ITS) region, the combined data analysis of ITS and the nuclear large subunit (LSU) rDNA, and their phenotype. Based on ITS phylogeny, within the Keratinophyton clade, K. lemmensii is clustered with K. durum, K. hubeiense, K. submersum and K. siglerae, while K. gollerae, K. straussii and K. wagneri are resolved in a separate terminal cluster. All four new species can be well distinguished from other asexual morphs in the genus Keratinophyton based on phenotypical characteristics alone. Ten new combinations are proposed for Chrysosporium asexual morphs which are resolved in the monophyletic Keratinophyton clade.

In the article is conducted an analysis of structure of life–form of types of species of the genus Veronica and shallow families of Callitrichaceae and Plantaginaceae is for determination of criteria of their associacion in new family of Plantaginaceae, distinguished in molecular–phylloginatec system APG ІІІ. Based on molecular–phylloginatec explorations the family of Scrophulariaceae collide on seven monophyletic clade. Veronicaceae clade is one of the biggest line orders Lamiales, now it is rised to the rang of the family and named Plantaginaceae. Molecular researches confirmed integrity of clade on a 98%. System APG operates only monophyletic units, that causes her considerable differences from evolutionary – morphological. Therefore, at the construction of the new system is necessary to take morphological, ecological features and principles of evolutionary systematization into account. We have learnt the most wide types of families of the life form structure, such as Veronicа, Callitrichace, Plantaginо. Veronica chamaedrys can be refered to types of sympodial creeping longrooted, herbal polycarpic aklonalnyj types life–form, with anizotropical, monopodial, non–rosette monocarpic shoots and by frondozed inflorescence. Veronica serpyllifolia that is creeping rooted of few (3 – 4) year life forms aklonalnyj types with non–rosette, anisotropy, monocarpial monopodial shoots, which gradually moving to tasssels. At the brought weed plant of Veronica persica during one year the life–form of rodrooted is formed clone form renascent with the anisotropic type of extended monocarpical of monopodial shoots. Similarity of structure of flower, in particular stamen vehicle, reduction of duration of life cycle from perennial to little old and annual plant to unite these species in one clade ad. However, development of life form depends anymore on the terms of environment, than genotype. While generative area of plant is more conservative.

Interesting Species

AbstractCollections of microfungi on bamboo and grasses in Thailand revealed an interesting species morphologically resembling Lophiostoma, but which can be distinguished from the latter based on multi-locus phylogeny. In this paper, a new genus, Sublophiostoma is introduced to accommodate the taxon, S. thailandica sp. nov. Phylogenetic analyses using combined ITS, LSU, RPB2, SSU, and TEF sequences demonstrate that six strains of the new species form a distinct clade within Pleosporales, but cannot be assigned to any existing family. Therefore, a new family Sublophiostomataceae (Pleosporales) is introduced to accommodate the new genus. The sexual morph of Sublophiostomataceae is characterized by subglobose to hemisphaerical, ostiolate ascomata, with crest-like openings, a peridium with cells of textura angularis to textura epidermoidea, cylindric-clavate asci with a bulbous or foot-like narrow pedicel and a well-developed ocular chamber, and hyaline, fusiform, 1-septate ascospores surrounded by a large mucilaginous sheath. The asexual morph (coelomycetous) of the species are observed on culture media.

Lycodon gongshanVogel and Luo, 2011 is a newly described snake species that is endemic to southwestern China. Based on two mtDNA gene fragments and two nuclear genes, a molecular phylogeny for the genusLycodonwas reconstructed and the systematic position ofL. gongshanwas evaluated. The results revealed thatL. gongshanformed a strongly supported monophyletic clade withL. fasciatus, and (L. cavernicolus +L. butleri), although the relationships among them were unresolved. The close genetic relationship betweenL. gongshanandL. fasciatusis consistent with hypotheses based on morphological data. Additionally two specimens from Guangdong, previously identified asL. fasciatus, showed a sister relationship withL. liuchengchaoiwith low genetic difference, indicating that the two specimens were misidentified, and illustrating thatL. liuchengchaoimay have much broader distribution than previous thought.

Collections of microfungi on Pandanus species (Pandanaceae) in Krabi, Thailand resulted in the discovery of a new species in the genus Parasarcopodium, producing both its sexual and asexual morphs. In this paper, we introduce P. pandanicola sp. nov., with an illustrated account. Evidence for the new species is provided by distinct morphology and phylogenetic analyses. This is also the first report of the sexual morph of Parasarcopodium. The phylogenetic trees used Maximum Likelihood and Bayesian analyses of combined LSU, SSU, TEF1 and RPB2 sequence data to show the placement of the new species in Stachybotryaceae.
