Abstract Two new species from southern China, Russula subpunicea and R. albolutea, were described and illustrated. Russula subpunicea is characterized by a pinkish to dark pink pileus with striations at the margin, white lamellae without lamellulae, subglobose to broadly ellipsoid to ellipsoid basidiospores with warts and spines sometimes joined to form a reticulum, hymenial cystidia that are mainly clavate, a suprapellis mainly composed of chains of short inflated cells with attenuated terminal cells and pileocystidia that are mainly clavate and turn reddish in sulfovanillin. Russula albolutea is recognized by a yellowish white pileus with long striations at the margin, a white stipe with a yellowish tinge, subglobose to broadly ellipsoid to ellipsoid basidiospores, hymenial cystidia that are mainly clavate and apically often obtuse and turn mauve in sulfovanillin, and a suprapellis mainly consisting of chains of short inflated cells with attenuated terminal cells. In this study, we performed phylogenetic analysis based on the ITS-nrLSU-RPB2-mtSSU dataset. By combining detailed morphological features with multigene phylogenetic evidence, we assigned the new taxa to Russula subsect. Virescentinae.

Two new species of Russula are described and illustrated in this paper. Russula clavulus is recognised by a pale yellow pileus centre, white margin with tuberculate striation, white to pale lamellae with small pale yellow spots, white to light yellow spore print, subglobose to broadly ellipsoid spores with short or long ridges and hymenial cystidia on lamellae sides that are mainly subclavate or fusiform. Russula multilamellula is morphologically characterised by the brownish orange to hazel pileus centre and satin white to yellowish-white margin with brownish tinge, lamellulae that are usually irregular in length and often anastomosing with lamellae, subglobose to broadly ellipsoid spores with short or long ridges and clavate hymenial cystidia. The combination of morphological features and multigene phylogenetic analyses of ITS-nrLSU-RPB2-mtSSU data indicated that these two new taxa belong to Russula subg. Heterophyllidia sect. Ingratae.

Since the phylogenetic analysis of the Herrichella clade (Ochlerini) new genera were described to fit monophyletic groups inferred and considered to be new taxa. The clade I supported by two synapomorphies of the female genitalia, grouped Alitocoris brunneus Sailer together to two new species. Alloeogyna gen. nov. is described here for this clade including the two new species Alloeogyna ampla sp. nov. and Alloeogyna poecila sp. nov. and a new combination is proposed for Alloeogyna brunnea comb. nov.. Also, Alitocoris maculosus Sailer recovered within the clade E in the Herrichella clade is here redescribed in the monotypic Sailerus gen. nov. resulting in the new combination Sailerus maculosus comb. nov..

Species of Clavaria (Clavariaceae, Agaricales) collected from China were studied using morphological and molecular methods. Two species, C. griseolilacina and C. sinensis were described as new species; both possess branched and pale purple-tinged fruit bodies. However, the former possess a few branched, while the latter is profusely branched. The phylogenetic analysis based on the internal transcribed spacer (ITS) sequences confirmed the distinctions between these two new species and their close relationships with C. rubicundula and C. fumosa in the genus. An evolutionary tendency in genus Clavaria was discussed. Additionally, morphological features of the two new species were described in detail and were illustrated with line drawings and photographs. Holotypes of the new species are deposited in the Mycological Herbarium of Hunan Normal University (MHHNU). The ITS sequences generated in this study were deposited in GenBank. A key is provided for the known Clavaria species in China.

We here describe two new species Arachniodes libingii and A. vietnamensis (Dryopteridaceae) from southern China and central Vietnam, respectively. Our previous phylogenetic analysis found a close relationship between the two new species. Further morphological studies showed that the two species share short creeping rhizomes, blackish brown and lanceolate scales, papery laminae, aristate pinnules, dense scales along fronds, and entire indusia. However, A. libingii has deltoid-oblong laminae and apices abruptly acuminate-caudate, while A. vietnamensis has shortly ovate laminae and apices gradually acuminate.

Two new species of Chalciporus are described from southern China. Chalciporus citrinoaurantius sp. nov. is characterized by a lemon yellow to grayish orange pileus, light orange to rose pink tubes and elongated basidiospores (9.0)9.5–12.5(13) × 3–4(4.5) μm; C. hainanensis sp. nov. is characterized by small basidiomata with grayish yellow to brownish orange pilei, orange yellow to brownish orange tubes with brownish orange to brownish red pores and elliptic basidiospores 8–10.5(11) × 4–5(5.5) μm. Phylogenetic analysis based on the combined dataset (nrLSU+tef1-α+rpb2) confirmed the affinity of the new species in Chalciporus and indicated their relationships with other species within the genus.

Two new Phallus species, P. cremeo-ochraceus and P. rigidiindusiatus were discovered in southwestern and southern China, respectively. Phallus cremeo-ochraceus is morphologically characterized by its cream to ochraceous receptacle, white to very slightly pinkish indusium, white to pinkish pseudostipe and white to slightly purplish pink volva. Phallus rigidiindusiatus is characterized by a white to yellowish white receptacle, a strongly rigid indusium usually without serrated margin and smaller basidiospores than those of P. serratus. Phylogenetic positions of the two species are located in two independent lineages respectively. Detailed descriptions, color photographs, illustrations and a key to the related species are presented.

Two new species in the diatom genus Nitzschia were found in the middle intertidal zone, Xiamen Bay, southern China. Both new taxa belong to the subgenus Nitzschia, as inferred from the presence of a canal-raphe-conopeum system. The valves of both new species are dorsiventral. In Nitzschia arierae sp. nov., the raphe system is positioned centrally, the conopea fuse to the valve face at supporting points, and the zone of valve face subtended by the conopeum has areolae. In Nitzschia gaoi sp. nov., the raphe system is centrally positioned or slightly eccentric, two large conopea extend out from near the raphe while two small conopea extend out from each transverse costa and cover the striae, most part of the zone of valve face subtended by the conopeum has no areolae, and there are two long produced rostrate apices that both arch toward the ventral side or one apex arches and the other is straight. Both new species are epipelic forms inhabiting the coastal environment.

A preliminary phylogeny of Fordiophyton (Melastomataceae) and the description of two new taxa, F. chenii and F. huizhouense, from southern China, are presented here. The phylogenetic analyses indicate that Fordiophyton is monophyletic and the two new species are in this clade of Sonerileae. Fordiophyton chenii is morphologically similar to F. cordifolium. Both taxa have glabrous stems, large, cordate leaves and four-sided petioles, but F. chenii has a very short stem, rosette leaves, hypanthia with dense glandular trichomes, and the shorter stamens with yellow anthers. Fordiophyton huizhouense shares with F. peperomiifolium the short, densely hirsute stem and rosette leaves, but F. huizhouense is characterized by adaxially smooth leaves, lanceolate calyx lobes, and inflated, prolonged connective bases in the longer stamens.

In this third contribution involving new Cantharellus species from South Korea, two new species are introduced. In addition, we document a first report of the recently described Japanese Cantharellus anzutake outside of Japan based on identical ITS sequence data. Cantharellus citrinussp. nov. is introduced as a new member of subgenus Cinnabarini, to which the closely related Korean C. albovenosus and Chinese C. phloginus also belong. Cantharellus curvatussp. nov. is introduced as a new member of subgenus Parvocantharellus, in which the Korean C. koreanus was recently placed. The respective placements of the new taxa are significantly supported by a phylogenetic analysis of sequences from the transcription elongation factor (tef-1).

Two new species of Macrostomum (Platyhelminthes: Macrostomorpha), M. shiyanensis n. sp. and M. lankouensis n. sp. are described from Shiyan Reservoir and Lankou Town. Morphological characteristics of the penis stylets and sperm, as well as the phylogenetic analysis using concatenated sequences of 18S and 28S rDNA genes support the establishment of these two new species and indicate that they are closely related to M. sinensis and M. heyuanensis described from different regions of Guangdong province. Finally, the progress of molecular phylogenetics of Macrostomum worldwide is also discussed.
