Euphorbia mbuinzauensis, a succulent new species of the Synadenium group in Euphorbiaceae from Makueni County, Kenya, is described and illustrated. Morphologically, it is most similar to E. pseudomollis, but differs mainly by its shrubby habit (up to 4 m), abaxial leaves surfaces with densely stellate hairs, 2–4-forked cymes, smaller bracts (ca. 2.5 × 3.0 mm), smaller cyathia (6 mm wide), crimson glands without narrow smooth margin, smaller fruits (ca. 8 × 7 mm) and ovoid seeds (ca. 1.8 × 2.2 mm). Furthermore, we performed a molecular phylogenetic analysis of the Synadenium group in Euphorbia sect. Monadenium, based on complete nuclear ribosomal DNA (nrDNA) datasets. This phylogenetic inference also supports it to be a distinct species. The new species is assessed as Endangered using the IUCN criteria.

A New Species

Inocybe pakistanensis is described and illustrated as a new species based on morphological characters and molecular phylogenetic analysis of nuclear ribosomal DNA including the internal transcribed spacer (ITS) regions along with larger subunit (LSU). The distinctive basidiomata have a highly rimose and fibrillose golden brown pileus with a reddish brown, prominent umbo; ellipsoid to amygdaliform, slightly phasoeliform smooth basidiospores; and clamped septa in all the tissues. Molecular phylogenetic analysis supports the placement of I. pakistanensis in section Rimosae s. str.

Twenty-six new species of Saussurea (Asteraceae, Cardueae) from the Qinghai-Tibetan Plateau and adjacent regions are described and illustrated. Our molecular phylogenetic analysis based on the nuclear ribosomal DNA internal transcribed spacer (ITS) and two chloroplast DNA fragments (trnL-F and psbA-trnH) has shown that most of the new species are well recognized in the molecular tree, with their taxonomic affinities also largely revealed.

Phenetic Classification

A phylogenetic analysis of the genera of the strongyloid sub-family Cloacininae from macropodoid marsupials in Australasia was undertaken based on morphological characteristics and analysis of concatenated sequences (ITS+) of the first (ITS-1) and second (ITS-2) internal transcribed spacers of nuclear ribosomal DNA. Neither approach provided a robust phylogeny, but similarities between the two methods in terms of generic groupings suggested that substantial revision is needed of the current phenetic classification, with some of the key morphological characteristics currently used to define genera and tribes proving to be homoplasious.

The genus Pohlia Hedwig is a large moss genus that has been placed in the Bryaceae family as traditionally determined. However, a molecular phylogenetic analysis has indicated that the Pohlia genus is more closely related to genera that are traditionally classified into the Mniaceae or Mielichhoferiaceae families. In this study, we performed a molecular phylogenetic analysis using evidence from four chloroplast regions (atpB-rbcL, rps4, trnG, and trnL-trnF) and one nuclear ribosomal intragenic spacer region (ITS) using different methods (maximum parsimony, maximum likelihood, and Bayesian inference). The phylogenetic relationships between Pohlia and its related genera are discussed.         Two large clades among our samples were well supported in all of the datasets. The traditionally defined Bryaceae species, including Brachymenium pendulum, Bryum caespiticium, Bryum capillare, Anomobryum gemmigerum, and Rhodobryum ontariense, formed a monophyletic clade with high support. The second clade corresponding to the Mielichhoferiaceae-Mniaceae complex also had high support. All of the Pohlia, Mielichhoferia and Mniaceae samples were included in this latter clade.         The clearest result from the phylogenetic analysis is that the Pohlia genus is non-monophyletic. The analysis is identical when using three methods and concludes that Pohlia is closer to the genera in Mielichhoferiaceae and Mniaceae. A formal taxonomic treatment of this clade was not performed because we lacked sufficient specimens of the species, although this work will be included in a future study.

This paper describes four new Chromodoris species: Chromodoris balat sp. nov., Chromodoris baqe sp. nov., Chromodoris kalawakan sp. nov., and Chromodoris quagga sp. nov. We were able to distinguish 44 species level lineages within Chromodoris, expanding the Indo-Pacific species from 39 species. The phylogeny presented here provides slightly greater resolution of species relationships than do previous studies of this genus. Layton et al. (2018), determined that variable color patterns made it difficult to differentiate in living specimens of distinct species, but we provide some additional stable color characters that potentially help resolve this issue, as well as additional internal features that are useful in species delimitation and correlate with the molecular phylogenetic analysis.

A New Species

Pilaira australis, a new species of fungus in the coprophilous genus Pilaira, was isolated from emu (Dromaius novaehollandiae) faeces and is described. Morphologically, the species resembles other species in the genus, particularly P. moreaui, except differs in its unique combination of sporangiophore height and sporangiospore length. Molecular phylogenetic analysis indicates that P. australis is distinct from other species in the genus with two regions, the internal transcribed spacers (ITS) and a fragment of the pyrG gene, showing 91% and 90% identity to the nearest species, respectively. Ultrastructure features and carbon utilisation were determined for P. australis, and may provide characteristics for species identification in this genus.

A New Species

Codonopsis atriplicifolia (Campanulaceae) from western Sichuan, China, is described here as a new species, which is similar to C. subscaposa in a number of characters. The results of molecular phylogenetic analysis of 25 species of Codonopsis based on chloroplast DNA fragments (matK, petD with petB-petD, rbcL) show that C. atriplicifolia is closely related to C. farreri. In morphology, the new species is distinctly different from the allied species by its linear-lanceolate leaves with subentire to pinnatipartite margins.

A New Species

A new species, Scrophularia jinii (Scrophulariaceae), from Central China is described and illustrated. This new species was formerly misidentified as S. fargesii, from which it differs in many morphological characters. Moreover, it is distinct with all known Scrophularia species in its unique deeply double serrate leaf margin with 3–7 big teeth on each side. Molecular phylogenetic analysis further supports its species delimitation and suggests a close relationship with several Japanese and North American species.
