Abstract Background Hyoscyamus, the largest genus in the tribe Hyoscyameae, harbors more than 20 species. Although the monophyly of Hyoscyamus is supported by both morphological and molecular phylogenetic studies, the delimitation of Hyoscyamus has been hotly debated in different classifications. Here, we report a new species of Hyoscyamus (Solanaceae) from Henan Province, China, and discuss the delimitation of Hyoscyamus. Results This species is morphologically similar to the known species of Hyoscyamus and its close related genus Archihyoscyamus, but can be distinguished by corolla 2-lipped, adaxial lip 3-lobed and much longer than abaxial lips, tube slender at base, and stamens 5, inserted on inner side of disk, free, obviously unequal, and exceeding corolla. Phylogenetic analysis based on four chloroplast markers including rbcL, ndhF, trnC-psbM and trnL-trnF, strongly suggested that the new species was sister to a monophyletic group containing all species of Hyoscyamus and Archihyoscyamus previously described. Conclusions Both the morphological observations and molecular phylogenetic analyses support the recognition of Hyoscyamus labiatus as a new species. Our study also showed that Archihyoscyamus should be a synonym of Hyoscyamus. The delimitation of Hyoscyamus is thus revised in our study.

Based on morphological and molecular phylogenetic studies, Semiaquilegia danxiashanensis, a new species from Danxia Shan in northern Guangdong, southern China, is described and illustrated. This species is easily distinguishable from each of other three known species in the genus by characters of the flowers and fruits. In addition, molecular phylogenetic analyses of both the nuclear ITS and the plastid trnL-F region strongly supported S. danxiashanensis as a separate species from other species of Semiaquilegia. We provide a detailed morphological and habitat description, distribution, as well as colour photographs and illustrations of the new species.

The genus Phillipsia (Sarcoscyphaceae) is characterized by large, bright-coloured, sub-stipitate apothecia, sub-operculate asci and asymmetrical ascospores with longitudinal striations. Morphological and phylogenetic studies were carried out on new collections of Phillipsia from China and Thailand. Phillipsia subpurpurea are recorded from China and Phillipsia gelatinosa from Thailand is introduced as a new species to science. Our new collections are confirmed to be divergent from other species of Phillipsia based on morphological examination and molecular phylogenetic analyses of ITS and LSU sequence data. Descriptions and figures are provided for the taxa which are also compared with allied taxa.

Colletotrichum has numerous host range and distribution. Its species are important plant pathogens, endophytes and saprobes. Colletotrichum can cause regular or irregular depressions and necrotic lesions in the epidermal tissues of plants. During this research Colletotrichum specimens were collected from Mengyin County, Shandong Province, China. A multi-locus phylogenetic analysis of ITS, GAPDH, CHS-1, ACT, TUB2, CAL and GS sequence data combined with morphology, revealed a new species and two known species, viz. C. mengyinense sp. nov., C. gloeosporioides and C. pandanicola, belonging to the C. gloeosporioides species complex. The new species is described and illustrated in this paper and compared with taxa in the C. gloeosporioides species complex.

Six species of the genus Rhabdosciadium (Apiaceae) were studied by molecular phylogenetic analysis. The taxonomic status of each of them has been confirmed, the genus Rhabdosciadium turns out as a well-supported monophyletic group closely related to the genera Aegopodium, Caropodium, Carum, Falcaria, Fuernrohria, Gongylosciadium, Grammosciadium s.s., Hladnikia, Olymposciadium, etc. Rhabdosciadium anatolyi sp. nov. is described and illustrated as a new species from Hakkâri province, eastern Turkey. It differs from the other taxa of the genus, in addition to its unique geographical range, in the large terminal leaf lobes with regularly serrated margin, mainly ternate primary basal segments of leaves, and long internodes.

Rubia hangii, a new species of Rubia sect. Oligoneura from Guangxi Province, China, is described and illustrated. The placement of this species within Rubia is assessed based on a molecular phylogenetic analysis and morphological comparisons with related species. The new species is morphologically similar to R. siamensis and R. falciformis, but differs from the two taxa in having membranous to thin papery leaf blade, margins flat , slender petiole (< 1 mm wide), ovate-lanceolate stipule, triangular corolla lobes, fruit glabrous, with 1 ovule often aborted and 1 mericarp developed, rarely with 2 mericarps. Molecular phylogenetic analyses suggested that R. hangii is closely related to R. argyi and R. pallida. Rubia hangii can be easily distinguished from R. argyi and R. pallida based on leaf and stipule arrangement, leaf shape, number of principal veins, inflorescence position and flower shape.

The genus Pseudepione Inoue, 1943 is a small geometrid taxon comprising only two species, the typo species P. magnaria (Wileman, 1911) and P. shiraii Inoue, 1943. They are known to distribute in Japan (Honshu, Kyushu and Shikoku), south and central Korea (Choi 2012; Choi & An 2010; Jung & Oh 2012), the former species was also reported in Jiangxi of China (Fang 2003). The genus seems to be univoltine since adults can only be found in the autumn season (Wileman 1911; Inoue 1943, 1982; Parsons et al. 1999; Kim & Beljaev 2001; Sato 2011; Choi 2012). The combination of the absence of forewing fovea, tuft of scales of third abdominal sternite, gnathos, socii and cormata is quite unique in Ennominae. So far, the phylogenetic affinity of Pseudepione is unclear since the closely related genus has never been proposed and still no morphological or molecular phylogenetic studies, i.e. Beljaev (2006a; 2006b; 2016), Sihvonen (2011), Yamamoto & Sota (2007), Jiang et al. (2017), considering the palaearctic subfamily or tribal levels sampled this genus. The dense fundamental surveys conducted in recent 7 years in the cloud forests of Taiwan acquire the opportunity to collect this genus new to Taiwan. After comparing the Taiwanese specimens with the known two species in both sexes, it’s clear the Taiwanese specimens are a distinct species needed to be described in the present study.

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.

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, 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.
