Fungal Genus

A strain of the fungal genus Mariannaea, isolated from decayed leaves of Japanese red pine (Pinus densiflora), was identified to be a new species based on its molecular phylogeny and morphology. Molecular phylogenetic analysis revealed that the fungus belongs to a clade containing M. punicea and related species (M. punicea-related species) and that it forms a lineage independent of these species. Microscopic morphological comparisons with M. punicea-related species indicated that the new isolate differs with respect to the width of the phialides and length of the conidiophores. Comparison of macroscopic morphological characteristics revealed that M. punicea-related species are characterized by reddish-purple colonies, whereas the new isolate lacks this distinctive pigmentation. Moreover, the surface structure of the colonies of this fungus has a distinct irregular undulate pattern toward the margins. Given that this isolate can be clearly distinguished from the known M. punicea-related species, we consider the fungus to be a newly identified species, for which we propose the name Mariannaea imbricata sp. nov.

Allium xinlongense from western Sichuan Province, China, is described as a new species. Its diagnostic morphological characters were confirmed to be valid by comparing them to those of related species, such as A. maowenense, A. chrysanthum, A. rude, A. xichuanense, A. chrysocephalum, and A. herderianum. Molecular phylogenetic analysis (combining ITS and rpL32-trnL markers) indicated that this new species is a member of Allium sect. Daghestanica. A comprehensive description of this new species is provided, including habitat environment and detailed morphological traits.

Sorbus dolichofoliolatus (Rosaceae) sp. nov. from Yunnan Province, China, is described and illustrated based on the collections deposited at the herbarium CDBI. The new species is similar to S. rehderiana in infructescence with sparsely rust-brown short hairs, fruit size, and glabrescent leaflets, but the former has longer and wider leaflets, persistent stipules and pinkish fruit color. A molecular phylogenetic analysis supports that the new species is distinguishable from related species in the genus.

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.

Phytolacca exiensis, a new species of Phytolacca which was discovered from west of Hubei province, China, is discribed and illustrated in this paper. The placement of this new species is accessed based on molecular phylogenetic analysis of the nuclear ribosomal ITS and one chloroplast regions (psbA-trnH) sequences together with mophorlogical comparison. This new species can be easily distinguished from other related species by its carpers connate and plants dioecious.

Youngia zhengyiana, a new species of Youngia sect. Mesomeris (Asteraceae: Crepidinae) from Guizhou province of south China is described and illustrated. The placement of this species within Youngia is assessed based on a molecular phylogenetic analysis of the nuclear ribosomal ITS and on morphological comparisons with related species. The new species can be easily distinguished by morphology from the only species known to possess 5 florets, Y. szechuanica. The infrageneric classification and the recently debated circumscription of Youngia are discussed in the light of the nrITS phylogeny, which includes several species for the first time. Pseudoyoungia is confirmed as a congener of Youngia. The redefined Youngia is still non-monophyletic with Lapsanastrum nested within it.

Basidiocarps of an undescribed dacrymycetous species were collected from Pinus densiflora forests in Japan and described as a new species, Femsjonia uniseptata, based on both morphological characteristics and phylogenetic analysis. This new species is characterized by having discoid to applanate basidiocarps with white hairs at the margins; thin-walled internal and marginal hyphae with clamp connections; and 0–1-septate basidiospores. A detailed description, line drawings, phylogenetic tree to show the placement of F. uniseptata and comparison of the new species with allied taxa are provided.

A New Species

We compared Sedum formosanum with related species using morphological traits and molecular phylogenetic analysis of nrITS sequences. Morphological comparisons revealed that the plants historically treated as S. formosanum in the Danjo Islands of Japan had 4-merous flower; 8 stamens; narrow triangular sepals of equal size; horizontal carpels when matured; and an irregular branching form. These traits differed from those of S. formosanum in other regions, which has 5-merous flowers; 10 stamens, thick spatulate sepals of unequal size; erect carpels when matured; and a trichotomous branching form. Phylogenetic analysis indicated that plants known as S. formosanum in the Danjo Islands were sister group to S. tetractinum, which are endemic to China and belong to a different clade than S. formosanum, which are found in other regions. Based on the present morphological comparisons and phylogenetical analyses, we describe plants from the Danjo Islands as a new species, S. danjoense, which is distinct from S. formosanum.

A New Species

A new poroid fungus, Nigrofomes submelanoporus, from tropical China, is described and illustrated based on morphological characteristics and phylogenetic analysis. The new species is characterized by perennial, resupinate to effused-reflexed, woody-hard and dark gray to almost black basidiocarps, lacerate dissepiments, a monomitic hyphal system, the presence of cystidioles and hyphal pegs, and broadly ellipsoid basidiospores (4–5.1 × 3.1–4.3 µm). Molecular analysis based on ITS sequences demonstrates the phylogenetic position of the new species in Nigrofomes. The discriminating characteristics between the new species and closely related species are discussed.
