Three dictyostelid isolates were found in Spain and Argentina that are morphologically different from known species. These isolates have some features similar to Dictyostelium sphaerocephalum (Oudem.) Sacc., Marchal & É.J. Marchal, but differ in size and sorocarp branching pattern. We sequenced the nuclear ribosomal internal transcribed spacer region to explore phylogenetic relationships among this group of species, including the three new isolates and their closest relatives. In all phylogenetic analyses performed, sequences of all three isolates group together with sequences from “typical” D. sphaerocephalum samples. This result supports previous observations of the morphological plasticity in dictyostelids, especially D. sphaerocephalum, leading us to broaden the classical concept of this species.

The Family

We describe two novel fungi isolated from soil samples collected in Northern Argentina and belonging to the family Aspergillaceae of the order Eurotiales: Leiothecium cristatum sp. nov. and Aspergillus posadasensis sp. nov. Leiothecium cristatum sp. nov., represented by the ex-type strain FMR 11998T ( = CBS 134260T = NBRC 109843T), is distinguishable morphologically from the type species of the genus, Leiothecium ellipsoideum, by the presence of irregular reticulate ascospores with two prominent equatorial crests, and Aspergillus posadasensis sp. nov., represented by the ex-type strain FMR 12168T ( = CBS 134259T = NBRC 109845T), is differentiated from Aspergillus acanthosporus, the nearest species phylogenetically, by its non-sclerotioid ascomata and a lack of an asexual stage on all culture media tested. The taxonomic proposals are supported by the analysis of the sequences of the internal transcribed spacer region, the D1–D2 domains of the 28S rRNA gene, the fragments of the RNA polymerase II largest subunit, and the putative chaperonin complex related to TCP-1, β-tubulin and calmodulin genes.

AbstractBy results of laboratory researches from plant samples of grain crops species Fusarium avenaceum, Fusarium tricinctum and Fusarium acuminatum related to Fusarium tricinctum species complex were isolated and identified, based on cultural and morphological characteristics, molecular-genetic analysis of 3 DNA fragments was performed: internal transcribed spacer (ITS) site, beta-tubulin gene site (TUB), elongation factor gene site (EF1) showed insignificant intraspecific and interspecific variability at ITS and EF1 sites, which may negatively affect the reliability of target species identification, TUB site was more effective for distinguishing and identifying the studied species, due to significant intraspecific and interspecific variability

Generic Relationships

Paralamium (Lamiaceae) is a monotypic genus within the subfamily Lamioideae and has a sporadic distribution in subtropical mountains of southeast Asia. Although recent studies have greatly improved our understanding of generic relationships within Lamioideae, the second most species-rich subfamily of Lamiaceae, the systematic position of Paralamium within the subfamily remains unclear. In this study, we investigate the phylogenetic placement of the genus using three datasets: (1) a 69,276 bp plastome alignment of Lamiaceae; (2) a five chloroplast DNA region dataset of tribe Pogostemoneae, and (3) a nuclear ribosomal internal transcribed spacer region dataset of Pogostemoneae. These analyses demonstrate that Paralamium is a member of Pogostemoneae and sister to the monotypic genus Craniotome. In addition, generic-level phylogenetic relationships within Pogostemoneae are also discussed, and a dichotomous key for genera within Pogostemoneae is provided.
