Hydnaceous fungi of China 7. Morphological and molecular characterization of Phellodon subconfluens sp. nov. from temperate, deciduous forests

A new hydnaceous fungus, Phellodon subconfluens, from northeast China, is described and illustrated based on morphological characteristics and rDNA ITS sequences. The new species is characterized by circular to flabelliform basidiocarps, a greyish buff, brownish orange to reddish brown and obscurely zonate pileal surface with white, incurved margins, a monomitic hyphal system with simple-septate, generative hyphae, and broadly ellipsoid to subglobose, thin-walled basidiospores with echinulate ornamentation. Molecular analysis confirms the phylogenetic position of the new species in Phellodon. The discriminating characters of the new species and closely related species are discussed.

Two new species of Tomentella from the Lesser Xingan Mts. of northeastern China, T. pallidocastanea and T. tenuirhizomorpha, are described and illustrated using morphological characteristics and molecular phylogenetic analysis. T. pallidocastanea is characterized by mucedinoid basidiocarps adherent to the substrate, a light reddish brown to pinkish grey hymenophoral surface, absence of rhizomorphs and cystidia, generative hyphae with clamps, rarely with simple septa and echinulate, and subglobose to lobed basidiospores (echinuli up to 1.5 μm long). T. tenuirhizomorpha is characterized by mucedinoid basidiocarps separable from the substrate, a greyish brown to dark brown hymenophoral surface, thin rhizomorphs in the subiculum and margins, an absence of cystidia, generative hyphae with clamps rarely with simple septa and echinulate, and subglobose to globose basidiospores (echinuli up to 1.5 μm long). Molecular analyses using Maximum Likelihood, Maximum Parsimony and Bayesian Analysis confirm the phylogenetic position of the two new species. The discriminating characters of these two new species and their closely related species are discussed in this study.

Some nematologists recently placed the genus Pratylenchoides, (“Lesion Nematode-like”) in the family Merliniidae. To investigate Pratylenchoides species diversity and their relationships with other Merliniidae genera, specimens were collected from various habitats in the northern and northwestern provinces of Iran. The morphological and molecular study yielded three species of the genus Pratylenchoides, including P. persicus n. sp. This new species is characterized by having lip region rounded or slightly flattened anteriorly with four or five fine but distinct annuli, pharyngeal glands off-set or slightly overlapping the intestine dorsally, all three gland nuclei located anterior to the pharyngo-intestinal valve and tail cylindrical with truncate to low rounded terminus. Morphologically, P. persicus n. sp. can be distinguished from the most closely related species, P. heathi by having shorter body and stylet length in females and males, as well as a shorter tail with different terminus in females. Pratylenchoides laticauda and P. cf. nevadensis are reported from Iran for the first time. Phylogenetic analysis based on the D2/D3 region of the large subunit of ribosomal DNA revealed Pratylenchoides as a monophyletic genus, and it supports the delineation of the new species, P. persicus n. sp.

Cortinarius alpinus as an example for morphological and phylogenetic species concepts in ectomycorrhizal fungiExtensive morphological and molecular analyses of closely related species from alpine, subalpine and montane habitats should enable a comparison of ecological, morphological and phylogenetic species concepts in ectomycorrhizal mushrooms. One fundamental question of this study was whether alpine species really exist, and which criteria, besides the specific habitat, could reliably be used for the de-limitation of such taxa. For this reason, 56 rDNA ITS sequences were generated or downloaded from GenBank for 10 closely related species of Cortinarius subgenus Myxacium, section Myxacium. Several collections were sequenced for each of the following taxa: Cortinarius absarokensis, C. alpinus, C. favrei, C. fennoscandicus, C. grallipes, C. mucosus, C. muscigenus, C. septentrionalis, C. trivialis and C. vernicosus. Moreover, spore statistics were carried out for 38 collections of alpine and subalpine taxa. These data provide clear evidence for C. favrei being a synonym of C. alpinus. C. absarokensis and C. alpinus can clearly be delimited based on pileus diameter and average dry weight per basidiome, even in overlapping habitats, but spore size and shape is not a good distinguishing character. Phylograms have very short branches, and base differences between ITS sequences are generally very low in this group, and give no resolution for the included taxa of this section. Based on these results, species concepts of ectomycorrhizal mushrooms are discussed in detail.

Buzionema lutgardae n. sp. (Nematoda: Oxyuridomorpha: Thelastomatidae) is described from the cockroach Byrsotria sp. (Blattaria: Blaberidae), endemic to Cuba. Females of B. lutgardae n. sp. are shorter than those of B. validum Kloss, 1966 (1600–2150 µm vs. 3131–3378 µm), but the oesophagus is comparatively longer (b = 2.96–3.77 vs. 4.65–4.87). The lateral alae of the new species extend from ca. the midpoint of the cylindrical part of the procorpus to the level of the anus in contrast to the base of the basal bulb to the level of the anus in B. validum. The males of B. lutgardae n. sp. are shorter than those of B. validum (780–940 µm vs. 1177–1423 µm) and their lateral alae end at some distance before the cloaca instead the level of the cloaca in B. validum. The phylogeny of B. lutgardae n. sp. is inferred by the D2-D3 domains of the 28S rDNA. B. lutgardae n. sp. and B. validum form a monophyletic clade with strong nodal support, as sister-group of the genus Leidynema Schwenck in Travassos, 1929.

A New Species

Abstract This study dealt with three species of ornamental palaemonid freshwater prawns of the genus Macrobrachium, based on morphological and molecular analysis. Macrobrachium pentazona He, Gao & Guo, 2009; M. laevis Zheng, Chen & Guo, 2019; and M. bilineare sp. nov. are distinguishable from closely related species by segmental ratios, spination of the second pereiopods and the slender scaphocerite. Macrobrachium bilineare sp. nov. can easily be recognized in the field by its bright colour pattern. Molecular evidence of mitochondrial cytochrome oxidase subunit I (COI), also supports the characterization of this new species, raising the total number of Macrobrachium spp. known from China to 41. Detailed description, illustrations, colour photographs, habitat information, distribution maps and features of conservation significance are also briefly discussed.
