We describe herein the Neoalbatrellus odorus sp. nov. accounting on its peculiar morphological features and molecular data. It is characterized by fleshy basidiomata with a deep violet to dark violet pileal surface, which turns blackish blue and glossy after drying. It also has a white pore surface, light violet to bluish violet stipe, simple septate generative hyphae, and thick-walled, non-amyloid basidiospores. The phylogenetic analyses, based on ITS and 28S rDNA sequences of Neoalbatrellus and its related genera, were performed using Maximum Parsimony, Maximum Likelihood and Bayesian Inference, confirming the affiliation of the new species to Neoalbatrellus.

Two new species, Xylodon bambusinus and X. xinpingensis, are proposed based on morphological and molecular evidences. Both species share the annual growth habit, resupinate basidiomata and monomitic hyphal system with clamped, colorless generative hyphae, smooth, thin-walled basidiospores, but X. bambusinus is characterized by the smooth to tuberculate hymenial surface, presence of capitate and fusiform cystidia, broad ellipsoid basidiospores, while X. xinpingensis by the reticulate hymenophore with cream hymenial surface, and subglobose basidiospores (4.5–6 × 3.5–5 µm). Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses based on molecular data of ITS and ITS+nLSU sequences showed that X. bambusinus was sister to X. subclavatus, while X. xinpingensis grouped with X. astrocystidiatus and X. paradoxus. The nLSU dataset revealed that X. bambusinus grouped with X. asperus and X. brevisetus with lower supports, and that X. xinpingensis grouped with X. astrocystidiatus and X. paradoxus and then with X. rimosissimus without supports. Both morphological and molecular evidences confirmed the placement of two new species in Xylodon. Description and figures from the new species and a key to the known species of Xylodon from China are presented.

Abstract Acanthogyrus (Acanthosentis) maroccanus (Dollfus, 1951), an insufficiently described quadrigyrid acanthocephalan of cyprinid fishes from Northwest Africa, is redescribed based on recently collected specimens from the Algerian barb Luciobarbus callensis (Valenciennes) in Algeria. Newly observed morphological features for A. (A.) maroccanus include the arrangement of proboscis hooks (not in regular circles), the male reproductive structures extending into the copulatory bursa and the presence of a para-receptacle structure and vaginal sleeve. The mechanism of copulation of this acanthocephalan is described based on several copulating pairs. The phylogenetic position of A. (A.) maroccanus within Eoacanthocephala was assessed based on partial 28S rDNA sequences. Maximum likelihood and Bayesian inference analyses placed A. (A.) maroccanus in a clade with Palliolisentis (Demidueterospinus) ophiocephalus (Thapar, 1931), both species included in the Quadrigyridae, the only family within the Gyracanthocephala.

Devibursaphelenchus kheirii sp. n. is described and illustrated based on morphological, morphometric and molecular data. The new species is characterised by females with 370-472 μm body length, lip region separated from the body by a shallow constriction, three lines in lateral field, stylet short, 13.5-15.0 μm long, lacking basal knobs or swellings, excretory pore posterior to metacorpus, vulval flap absent, post-uterine sac short, without sperm, rectum and anus obscure, posterior end of the body elongate-conoid with finely rounded terminus. Males of the new species are characterised by their tail ventrally curved after fixation, having two pairs of caudal papillae, spicules 9-11 μm long with an elongated condylus, with rounded tip, pointed rostrum, lacking cucullus and having small conical terminal bursa. The new species comes close to D. hunanensis, D. lini and D. wangi. Beside morphological comparisons, the molecular phylogenetic analyses based on 778 bp of partial sequences of 28S rDNA D2-D3 were performed using two Bayesian inference (BI) and maximum likelihood (ML) methods and revealed that D. kheirii sp. n. formed a clade with the remaining species of the genus and one species of Ektaphelenchoides. This is the first report on occurrence of the genus Devibursaphelenchus in Iran. Devibursaphelenchus eproctatus syn. n. is proposed as a junior synonym of D. hunanensis.

Morphological Species

Unlike most phialide-producing fungi that liberate a multiplicity of conidia from each conidiogenous cell, only single conidia are formed on phialide-like conidiogenous cells in Aphanocladium, Verticimonosporium, and some species of Sibirina. A group of isolates obtained from soil of native Artemisia tridentata (sagebrush) grassland in Wyoming and from desert soil in Iraq is compared with these genera and classified as a fourth genus, Stanjemonium, honouring Stanley J. Hughes. Phylogenetic analyses of partial nuclear small- (18S) and large-subunit (28S) rDNA sequences indicate that Stanjemonium spp. form a monophyletic group with Emericellopsis. Sequences from the nuclear 18S and 28S rDNA were too conserved to resolve morphological species of Stanjemonium; however, phylogenetic analysis of b-tubulin and translation elongation factor 1a gene exons and introns resolved all species distinguished morphologically. Numerous conidiogenous cells or denticles are scattered along the cells of aerial hyphae in Aphanocladium and Stanjemonium spp., very rapidly collapsing into denticles in the former, somewhat more persistent and leaving broad scars in the latter. In Cladobotryum-Sibirina and Verticimonosporium spp., conidiogenous cells are discrete in terminal and intercalary whorls; phialides of the latter taxon are particularly swollen. The taxonomy of Aphanocladium is not yet resolved. Two species are recognized in Verticimonosporium. Three new species of Stanjemonium are described, and one new combination from Aphanocladium is proposed, along with one new species of Cladobotryum.Key words: Aphanocladium, Cladobotryum, conidiogenesis, hyphomycetes, molecular phylogeny, phialide, Stanjemonium, systematics, Verticimonosporium.

A New Species

Tubaria squamata is described as new from Jiaohe county, Jilin province, China. This species is distinctive morphologically because of the small (slightly) hairy or scaly pileus, subelliptic to elliptic non-amyloid basidiospores, subclavate to cylindrical or lageniform cheilocystidia, and a pileipellis as a cutis. Phylogenetic analyses based on internal transcribed spacer sequences with Bayesian Inference analysis (BA) and Maximum Likelihood (ML) showed that T. squamata is different from related species. Illustrations and a complete taxonomic description are also provided, as well as a key to the Tubaria species known from China.

Two Populations

Two populations of Xiphinema ingens were recovered and characterised based on morphological, morphometric and molecular data. Interesting morphological variation was observed on the nature of differentiation in uterus of females between both populations, i.e. one population had only a pseudo-Z-organ in the shape of globular bodies, whilst the second population had a similar pseudo-Z-organ but also had crystalloids which varied in size and number and were located near the pseudo-Z-globules or sometimes at some distance from them towards the vagina. Variation was also observed in the shape of tail of juveniles within each population as well as between two recovered populations. Both populations had the same range of morphometric data and formed a fully supported clade in both Bayesian inference (BI) and maximum likelihood (ML) methods of phylogenetic analyses using partial sequences of 28S rDNA D2-D3 and ITS1 regions. The two populations of X. ingens formed a clade with another Xiphinema species native to Iran (X. castilloi) in 28S and two species, X. macroacanthum and X. bernardi, in ITS1 trees.

A new wood-inhabiting fungus, Phlebia nigrodontea, is proposed based on a combination of morphological features and molecular evidence. The species is characterized by a grandinioid hymenophore with vinaceous brown to black colour, a monomitic hyphal system with clamped generative hyphae and ellipsoid, colourless, thin-walled, smooth basidiospores (3.9–4.9 × 2.3–3.1 µm). Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses carried out using maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses based on the molecular data of ITS+nLSU sequences showed that P. nigrodontea nested within the phlebioid clade. A further investigation of more representative taxa from Phlebia, based on ITS+nLSU sequences, demonstrated that the species P. nigrodontea formed a monophyletic lineage with strong support (100% BS, 100% BT, 1.00 BPP) and closely grouped with P. chrysocreas.

Sanghuangporus vitexicola (Hymenochaetales) is described as a new species based on collections made from Pingtung County, tropical South Taiwan. All studied basidiocarps grew on living trunks of Vitex negundo. This new species is characterized by having perennial, pileate basidiocarps; pore surface yellowish brown, pores 6–8 per mm; context 0.7–1.5 cm thick; setae ventricose to subulate, dark brown, 17–30 × 5–8 μm; basidiospores broadly ellipsoid, brownish, smooth, 4.2–4.8 × 3.2–3.7 μm, with 0.2–0.5 μm thick walls. Maximum likelihood and Bayesian inference phylogenies inferred from the internal transcribed spacer (ITS) region of rDNA indicated that six strains of Sanghuangporus viexicola formed a monophyletic group which is sister to S. zonatus. An identification key to known species of Sanghuangporus is provided.

Bauhinia species are popular ornamental and medicinal plants with a pantropical distribution. In December 2016, powdery mildew symptoms were found on B. blakeana and B. purpurea in Guangdong, China. Based on ITS and 28S rDNA sequences, as well as morphological characters, the powdery mildew was identified as Erysiphe lespedezae. Previous records of powdery mildews on Bauhinia spp. are discussed. Based on morphological and molecular phylogenetic analyses of type material, Pseudoidium caesalpiniacearum is reduced to synonymy with E. lespedezae. To our best knowledge, this is the first report of E. lespedezae causing powdery mildew on B. purpurea in China, and B. blakeana as a new host. A detailed morphological description and molecular data are provided herein.

Abstract Recently performed phylogenetic-taxonomic analyses of species belonging to Erysiphe sect. Uncinula on willows (Salix spp.) demonstrated a much higher diversity than previously assumed. Phylogenetic analyses and morphological examinations of Chinese Erysiphe collections on Salix abscondita (= S. raddeana), S. sinica and S. taraikensis, all belonging to Salix subgen. Vetrix sect. Vetrix, revealed an additional cryptic species in sister position to the E. salicis clade, which is described as Erysiphe salicina. The new species clearly distinguished from all allied species in morphological and genetical results. The phylogeny of the new species and closely related species on Populus and Salix spp. (Salicaceae) was reconstructed and discussed using a combined alignment of the internal transcribed spacer (ITS) regions and 28S rDNA sequences. The present phylogenetic analyses suggest that the recently described E. salicicola (on Salix gracilistyla in South Korea) has to be reduced to synonymy with E. salicis var. salicis-gracilistylae (º Uncinula salicis-gracilistylae).
