Summary Cystic echinococcosis (CE) and alveolar echinococcosis (AE) are considered as one of the most important zoonotic diseases in Romania, where they are subject to mandatory reporting. To obtain more knowledge about the genetic diversity of Echinococcus causative agents of these diseases, 11 isolates from humans and ungulate intermediate hosts from the two regions of Romania were genotyped using mitochondrial markers. In clinical samples of five patients from north-eastern Romania (Iasi, Botosani, Vaslui counties), Echinococcus multilocularis was identified as causal agent by cox1 sequence analysis. To the best of our knowledge this finding presents the first molecular evidence of E. multilocularis in humans from Romania. Only two cases of AE in patients were previously documented in the country by serological methods. In our four patients the most widespread European variant E5 of E. multilocularis was recorded, whereas in isolate from Vaslui county three nucleotide substitutions were detected as compared to the most related E5 haplotype. One of these mutations (411T/G) matched N1 and N2 haplotypes described previously from North America. In six CE samples retrieved from western Romania (Caras-Severin and Timis counties), two human isolates were diagnosed as Echinococcus canadensis G7, one as E. granulosus s.s. G1 and one as E. granulosus s.s. G3 using atp6 and rrnS sequencing. In ungulates, the cattle isolate was allocated to E. granulosus s.s. G1 and pig isolate to E. canadensis G7. The two G7 findings in humans reinforced the recent view that G7 was underestimated as compared to the E. granulosus s.s. regarding human CE threat that can be further employed for identifying sources of infections and establishing suitable preventive measures.

Recent molecular evidence supports the transfer of two Australian endemic species, Austrocynoglossum latifolium (R.Br.) R.R.Mill and Cynoglossum suaveolens R.Br., to the genus Hackelia Opiz as H. latifolia (R.R.Mill) Dimon & M.A.M.Renner, comb. nov., and H. suaveolens (R.Br.) Dimon & M.A.M.Renner, comb. nov. Hackelia latifolia comprises two morphological entities that, although sharing the procumbent-prostrate habit and production of elongated internodes and frondose bracts in the inflorescence, differ in a range of qualitative and quantitative micro-morphological characters. Hackelia latifolia has few, widely spaced, thorn-like trichomes on stems, a glabrous abaxial lamina surface, and mericarps with free glochids densely and evenly distributed over the outer surface, and a rectangular cicatrix at the mericarp apex, which is beaked. The other entity has many densely packed cellular trichomes on the stems, trichomes on the abaxial leaf lamina, and mericarps with a wing formed by basally connate glochids, and a triangular cicatrix located centrally on the inner mericarp surface. For the latter, we propose the new species Cynoglossum torvum Dimon & M.A.M.Renner, and by implication suggest that H. latifolia is polyphyletic as previously circumscribed. Whereas H. latifolia s.s. is widespread along the south-eastern coast of Australia from Tasmania to south-eastern Queensland, Cynoglossum torvum is restricted to the tablelands of north-eastern New South Wales and south-eastern Queensland. We compare C. torvum with the other Australian Cynoglossum L. species, C. australe R.Br., confirm previous observations of variation in mericarp morphology, and suggest that further investigation to resolve species circumscription is required given this variation.

AbstractCalathella eruciformis, a species hitherto unknown in Poland, is reported from four localities in the north-eastern part of the country. This wood-inhabiting saprotroph was found on dead decorticated but still attached twigs and branches of living Populus tremula in an oak-hornbeam forest (Carpinion betuli). Macro- and microcharacters of the recently collected material are presented in detail, together with selected illustrations. Examination of ITS rDNA sequences indicated that Calathella is not monophyletic and that the type species of the genus C. eruciformis is alien to the heterogeneous genus Flagelloscypha. Furthermore, molecular evidence is provided for a close relationship between C. eruciformis and the type species of the genus Sphaerobasidioscypha, Sphaerobasidioscypha citrispora.

Three species of the genus Asterina are known to inhabit the Mediterranean Sea and the north-eastern Atlantic Ocean: Asterina gibbosa (Pennant, 1777), A. pancerii (Gasco, 1870) and A. phylactica Emson & Crump, 1979. Differentiation of these species has primarily been based only on subtle characters (some highly debatable), such as colour or size. Therefore, this study aimed to review the morphological data characterising members of the genus, to incorporate new characters that may clarify morphological analyses and to couple morphological data with molecular evidence of differentiation based on the analysis of partial sequences of the cytochromec oxidase subunitI (COI) and 18S rDNA (18S) genes and two anonymous nuclear loci (AgX2 and AgX5). The different lineages and cryptic species identified from the molecular analysis were then morphologically characterised, which was challenging given the limited number of diagnostic characters. Two of the five monophyletic lineages obtained molecularly (COI divergence >4%), further supported by differences in morphological characters and reproductive behaviour, are proposed as new species: Asterina martinbarriosi, sp. nov. from the Canary Islands, Spain (eastern central Atlantic Ocean) and Asterina vicentae, sp. nov. from Tarragona, north-eastern Spain (western Mediterranean Sea).
