Two New Species

Amphisphaeria flava and A. thailandica sp. nov. collected from dead woody branches in northern Thailand, are described and illustrated in this study. Both taxa share ascomata with a brown outer peridium and 1-septate brown ascospores in uniseriate asci. Amphisphaeria flava is characterized by a pale yellow host surface around the ostiole, a comparatively thin peridium and multi-guttulate mature ascospores. Amphisphaeria thailandica is characterized by subglobose to oval ascospores. Maximum parsimony, maximum likelihood and Bayesian inference analyses of a combined LSU and ITS DNA sequence matrix shows that A. flava and A. thailandica are distinct from other Amphisphaeria species (with molecular data available) in family Amphisphaeriaceae. A key to accepted Amphisphaeria species is provided.

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.

Two new corticioid fungal species, Phanerochaete pruinosa and P. rhizomorpha spp. nov. are proposed based on a combination of morphological features and molecular evidence. Phanerochaete pruinosa is characterized by the resupinate basidiomata with the pruinose hymenial surface, a monomitic hyphal system with simple-septate generative hyphae and subcylindrical basidiospores measuring as 3.5–6.7 × 1.5–2.7 µm. Phanerochaete rhizomorpha is characterized by having a smooth hymenophore covered by orange hymenial surface, the presence of rhizomorphs, subulate cystidia, and narrower ellipsoid to ellipsoid basidiospores. Sequences of ITS+nLSU nrRNA gene regions of the studied specimens were generated and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. These phylogenetic analyses showed that two new species clustered into genus Phanerochaete, in which P. pruinosa was sister to P. yunnanensis with high supports (100% BS, 100% BT, 1.00 BPP); morphologically differing by a pale orange to greyish orange and densely cracked hymenial surface. Another species P. rhizomorpha was closely grouped with P. citrinosanguinea with lower supports; morphologically having yellow to reddish yellow hymenial surface, and smaller cystidia measuring as 31–48 × 2.3–4.8 µm.

A New Species

Phaeosphaeria ampeli is a new species collected from dead leaves of Ficus ampelas in Fanlu Township area, Dahu forest, Chiayi, Taiwan. Phaeosphaeria musae is a new record from dead leaves of Roystonea regia. Both species are described, illustrated and compared with similar species. Phaeosphaeria ampeli is distinguished from other Phaeosphaeria species based on distinct size differences of the ascomata, asci, ascospores and analyses of DNA sequence data. Maximum parsimony, maximum likelihood and Bayesian inference analyses of combined ITS, LSU, SSU and tef1-α sequence data are used to clarify the phylogenetic affinities of the species.

The Chenopodiaceae includes taxa with both C3 and C4 photosynthesis with diverse kinds of Kranz anatomy and single-celled C4 species without Kranz anatomy; thus, it is of key importance for understanding evolution of C4 photosynthesis. All of the C4 genera except Atriplex, which belongs to Chenopodioideae, are in the Salicornioideae / Suaedoideae / Salsoloideae s.l. (including Camphorosmeae and Sclerolaeneae) clade. Our study focused on the relationships of the main lineages within this clade with an emphasis on the placement of the single cell functioning C4 genus Bienertia using maximum parsimony, maximum likelihood, and Bayesian inference phylogenetic analyses of the nuclear ribosomal ITS and five chloroplast DNA regions (atpB-rbcL, matK, psbB-psbH, rbcL, and trnL-trnF). Further we provide a detailed phylogeny of Alexandra and Suaeda based on ITS, atpB-rbcL, and psbB-psbH. Our molecular data provide strong statistical support for the monophyly of: (1) a Salicornioideae / Suaedoideae / Salsoloideae s.l. clade; (2) a Salicornioideae / Suaedoideae clade; (3) the subfamilies Salicornioideae, Suaedoideae (including Bienertia) and Salsoloideae s.l.; (4) the tribes Suaedeae, Salsoleae, and Camphorosmeae; (5) the Salicornieae if Halopeplideae is included; and (6) Suaeda if Alexandra is included. Alexandra lehmannii is therefore reclassified as Suaeda lehmannii and a new section of Suaeda is created, section Alexandra. There are four independent origins of C4 photosynthesis within the Suaedoideae including two parallel origins of Kranz C4 anatomy (in Suaeda sections Salsina s.l. and Schoberia) and two independent origins of C4 systems without Kranz anatomy (in Bienertia and in Suaeda section Borszczowia).

Two new species ofFicophaguswere recovered, and are described herein asF. maximasp. n. andF. yoponensissp. n. fromFicus maximaandF. yoponensis, respectively. They are differentiated from other species of the genus by a combination of morphological characters including having C-shaped females and spiral males, EP opening close to the lips, a short to long post-uterine sac, spicule characters, three pairs of subventral caudal papillae, DNA sequence data, biogeographical range, and host wasp andFicusspecies affiliation. The new species are differentiated from each other by spicule characters, length of the post-uterine sac, spermatheca shape, and female tail shape. In addition, three morphospecies were collected from sycones ofFicus glabrata,F. insipidaandF. tonduzii, respectively. Their morphological descriptions are presented but these taxa are not formally named as they currently lack molecular data.

Two new species of Russula subg. Heterophyllidia from Guangdong Province of China were described and illustrated based on morphological characters, and their identity supported by molecular phylogeny. R. luofuensis is morphologically characterized by a grayish yellow to brownish orange pileus center with a purplish gray to grayish magenta margin, a surface that is cracked and broken into small golden-brown patches, subglobose to broadly ellipsoid basidiospores with warts fused in short or long chains and a suprapellis composed of hyphal extremities with inflated, ellipsoid or globose cells and attenuated terminal cell. R. subbubalina is distinguished by the blanched almond to dark salmon pileus that is cracked with age, subglobose to broadly ellipsoid basidiospores with wart fused in short or long chains and frequently connected by line connections, a suprapellis with hyphal ends composed of inflated or ellipsoid cells and attenuated terminal cell, and pileocystidia that are mainly clavate and sometimes with round or ellipsoid appendage. The phylogenetic analyses based on ITS-nrLSU-mtSSU-TEF1 dataset were performed using maximum likelihood and Bayesian analysis. In terms of morphological features and molecular data, the former species belongs to subsect. Virescentinae, whereas the latter comes under subsect. Heterophyllinae.

In this paper, two new species in Hyphodontia, H. bubalina and H. mongolica, are reported as new to science based on morphological characteristics and phylogenetic analyses. Detailed descriptions and illustrations are provided with comparisons among allied taxa. Hyphodontia bubalina has thin cream basidiomata, a monomitic hyphal system with thin- to slightly thick-walled generative hyphae, hyphoid or subulate cystidioles, ellipsoid to subglobose basidiospores measuring as 4–5.3 × 3–4.2 µm. Hyphodontia mongolica is characterized by the partly confluent or branched aculei, a monomitic hyphal system with thick-walled generative hyphae, clavate and tubular cystidia, and ellipsoid basidiospores measuring as 4.9–6.6 × 2.5–3.2 µm. Phylogenetic analyses based on the internal transcribed spacer (ITS) regions which performed by Bayesian (BI), maximum likelihood (ML) and maximum parsimony (MP) methods confirm to place the two species in the genus Hyphodontia.

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.

Three coelomycete species with muriform conidia were collected in Italy and subjected to morpho-molecular analyses. In morphology, all species are similar to Camarosporium sensu stricto. Based on morphology, one was identified as C. spartii and the other two taxa are introduced as new species, viz. C. clematidis and C. robiniicola. Maximum likelihood, maximum parsimony and Bayesian analyses of the combined LSU, SSU and ITS dataset show that the three taxa cluster with C. quaternatum, the type species of Camarosporium, with high bootstrap and PP values. All four species can be considered as Camarosporium sensu stricto. Cucurbitaria elongata groups in the Camarosporium clade near to Camarosporium robiniicola and is considered that it is not congeneric with Cucurbitaria sensu stricto (Cucurbitariaceae).
