Amanita subjunquillea and its ectomycorrhizal association are reported for the first time from moist temperate Himalayan forests of Pakistan. The sample was studied based on morphological characters and nucleotide sequence analyses of the ITS region generated from basidiomata and ectomycorrhizal roots of Quercus floribunda. Our collection differs from the type in its dark orange pileus disc and pale yellow margins. Remaining morphological and molecular data are consistent with previously reported specimens. This represents the first report of A. subjunquillea from Pakistan.

AbstractDue to importance and effectiveness of some entomopathogenic or insect parasitic nematodes in controlling of agricultural pests, or pests of non-agricultural plants, a study was conducted in order to identify the species of this group of nematodes in city of Tehran. As the result, three species belonging to the genusOscheiuswere recovered in association with bark samples having the bark beetle galleries. Morphological and molecular data were provided for two recently recovered species of the genus, namelyO. necromenusandO. onirici. Molecular data were also provided for a recently recovered isolate ofO. tipulae. All three species were recovered in association with bark samples collected from dead trees in the city of Tehran. Morphological characters and morphometric data of the two aforementioned species are in accordance with the data given in their original descriptions. One recovered individual from a small bark sample characterized by its short body length was sequenced for its 28S and internal transcribed spacer (ITS) rDNA loci, and the results of BLAST search using the newly obtained partial sequences revealed that it belonged toO. tipulae. Molecular phylogenetic studies revealed recently sequenced Iranian populations ofO. oniriciandO. tipulaeforming a clade with other isolates/populations of these species in ITS tree with maximal Bayesian posterior probability (BPP), and presently sequenced isolates ofO. tipulaeandO. necromenusform a clade with other isolates of these species in 28S tree. The two speciesO. oniriciandO. necromenuswere reported in Iran for the first time.

Abstract The phylogenetic position of most xiphidiocercariae from subgroups Cercariae virgulae and Cercariae microcotylae remains unknown or unclear, even at the family level. In this paper, we studied the morphology and molecular phylogeny of 15 microcotylous and virgulate cercariae (11 new and four previously described ones). Based on morphological and molecular data, we suggested five distinct morphological types of xiphidiocercariae, which are a practical alternative to Cercariae virgulae and Cercariae microcotylae subgroups. Four of these types correspond to actual digenean taxa (Microphallidae, Lecithodendriidae, Pleurogenidae and Prosthogonimidae), while the fifth is represented by Cercaria nigrospora Wergun, 1957, which we classified on the basis of molecular data for the first time. We reassessed the relative importance of morphological characters used for the classification of virgulate and microcotylous cercariae, and discussed the main evolutionary trends within xiphidiocercariae. Now stylet cercariae can be reliably placed into several sub-taxa of Microphalloidea on the basis of their morphological features.

Galianthe (Rubiaceae) is a neotropical genus comprising 50 species divided into two subgenera, Galianthe subgen. Galianthe, with 39 species and Galianthe subgen. Ebelia, with 11 species. The diagnostic features of the genus are: usually erect habit with xylopodium, distylous flowers arranged in lax thyrsoid inflorescences, bifid stigmas, 2-carpellate and longitudinally dehiscent fruits, with dehiscent valves or indehiscent mericarps, plump seeds or complanate with a wing-like strophiole, and pollen with double reticulum, rarely with a simple reticulum. This study focused on two species that were originally described under Diodia due to the occurrence of fruits indehiscent mericarps: Diodia palustris and D. spicata. In the present study, classical taxonomy is combined with molecular analyses. As a result, we propose that both Diodia species belong to Galianthe subgen. Ebelia. The molecular position within Galianthe, based on ITS and ETS sequences, has been supported by the following morphological characters: thyrsoid, spiciform or cymoidal inflorescences, bifid stigmas, pollen grains with a double reticulum, and indehiscent mericarps. However, both species, unlike the remainder of the genus Galianthe, have homostylous flowers, so the presence of this type of flower significantly modifies the generic concept. In this framework, a third homostylous species, Galianthe vasquezii, from the Andean region is also described. Until now, this species remained cryptic under specimens of Galianthe palustris It differs however from the latter by having longer calyx lobes, the presence of dispersed trichomes inside the corolla lobes (vs. glabrous), fruits that are acropetally dehiscent (vs. basipetally dehiscent), and its Andean geographical distribution (vs. Paranaense). Additionally, a lectotype has been chosen for Diodia palustris, Borreria pterophora has been placed under synonymy of Galianthe palustris, and Galianthe boliviana is reported for the first time from Peru. A key of all Galianthe species with indehiscent mericarps is also provided.

One enchytraeid species, proved to be new to science, is described in this paper as Fridericia ventrochaetosa sp. nov. The new species is distinguished from similar species, especially from F. galba (Hoffmeister, 1843), which has almost the same type of spermatheca, on the basis of morphological characters and molecular data (nuclear ribosomal ITS region, mitochondrial cytochrome c oxidase subunit I and nuclear histone 3 gene sequences). Apart form the new species, GenBank reference sequences are provided for the first time for F. hegemon and F. regularis. The results show that, although the shape of the spermatheca is a very important marker in the case of Fridericia species, other characters can be equally important for their taxonomic identification.

Lactarius subgenus Russularia is a dominant group of milkcaps in Southeast Asia. This paper reveals the large diversity   of the subgenus, with eight new species and one known species being described from montane evergreen and coniferous forests. All new species are supported by both morphological and molecular data, the latter using Maximum likelihood and Bayesian analysis based on the ITS region. Complete macro- and micro-morphological descriptions and illustrations are given. A key to the new taxa is provided. Lactarius chichuensis is reported for the first time from Thailand.

Sinalliaria is described here as a new genus of the family Brassicaceae from eastern China, based on the morphological characters and molecular sequences. Sinalliaria differs from the related genus Orychophragmus in having basal leaves petiolate, simple or rarely with 1‒3 lateral lobes (not pinnatisect); cauline leaves petiolate, cordate at base (not sessile, auriculate or amplexicaul at base); petals obovate to narrowly obovate, claw inconspicuous (not broadly obovate, with a claw as along as sepal); siliques truncate (not long-beaked) at apex. The microscopic characters of seed testa also show significant differences between Sinalliaria and Orychophragmus. Phylogenetic evidence from DNA sequences of nuclear ribosomal ITS and plastid region trnL-trnF indicates that Sinalliaria is a distinct group related to Orychophragmus and Raphanus, but these three genera do not form a clade. The new genus Sinalliaria is endemic to eastern China and has only one species and one variety. The new combinations, S. limprichtiana (Pax) X. F. Jin, Y. Y. Zhou & H. W. Zhang and S. limprichtiana var. grandifolia (Z. X. An) X. F. Jin, Y. Y. Zhou & H. W. Zhang are proposed here.

Clathrosporium retortum sp. nov., collected on submerged mixed leaf litter samples at Ilha do Cardoso State Park, São Paulo state, Brazil, is described based on morphological and molecular data. The fungus is characterized by forming whitish, dense, subglobose to irregular propagules, hyaline to subhyaline when young, subhyaline to dark brown at maturity, that are formed by densely interwoven conidial filaments with each conidial cell repeatedly branching bilaterally or occasionally unilaterally. Phylogenetic analyses using partial LSU nrDNA sequence data suggest that C. retortum belongs in the Sordariomycetes (Ascomycota) where it forms a well-supported clade with Clohesia corticola in the Sordariomycetidae, but its ordinal or familial placement remains unresolved. Its phylogenetic placement confirms the polyphyletic nature of aeroaquatic fungi like Clathrosporium, as it was distantly related to one available sequence in GenBank named as C. intricatum, the type species, which is phylogenetically related to the Helotiales (Leotiomycetes). However, due to lack of authenticity of the identity of this sequence with the type specimen of C. intricatum, a broad concept of Clathrosporium is tentatively adopted here to accommodate the present fungus instead of introducing a new genus. Beverwykella clathrata, Helicoön septatissimum and Peyronelina glomerulata are recorded for the first time from Brazil. Cancellidium applanatum and Candelabrum brocchiatum are new records for the state of São Paulo.

Autolytinae is revised based on available types, and newly collected specimens. Out of 170 nominal species, 18 are considered as incertae sedis, 43 are regarded as junior synonyms, and 25 are referred to as nomina dubia. The relationships of Autolytinae is assessed from 51 morphological characters and 211 states for 76 ingroup-taxa, and 460 molecular characters from mitochondrial 16S rDNA and nuclear 18S rDNA for 31 ingroup-taxa; outgroups include 12 non-autolytine syllid polychaetes. Two analyses are provided, one including morphological data only, and one with combined morphological and molecular data sets. The resulting strict consensus tree from the combined data is chosen for a reclassification. Three main clades are identified: Procerini trib. n., Autolytini Grube, 1850, and Epigamia gen. n. Proceraea Ehlers, 1864 and Myrianida Milne Edwards, 1845 are referred to as nomen protectum, while Scolopendra Slabber, 1781, Podonereis Blainville, 1818, Amytis Savigny, 1822, Polynice Savigny, 1822, and Nereisyllis Blainville, 1828 are considered

Parasesarma semperi (Bürger, 1893) was first described from Bohol in the Philippines and is considered to be widely distributed in Southeast Asia. Parasesarma longicristatum (Campbell, 1967) was originally described as a subspecies of P. semperi from Queensland, Australia, and later recognised as a full species. In this study, we re-examine specimens of the two species from across their entire geographic range using genetic markers, a morphometric analysis, and traditional morphological characters. Previous taxonomic species diagnoses were found to be unreliable, but morphometric principle component analyses consistently separate the two species, with the length to width ratio of the propodus of the fourth pereiopod being of particular importance. Genetic data corresponding to the mitochondrial genes COI, ND1 and 16S confirmed a close sister relationship between the two species, forming reciprocally monophyletic groups. Both species have high haplotype diversities and high intraspecific gene flow.

Hericium cirrhatum, a widespread but locally rare tooth fungus is reported for the first time from Pakistan. This species is characterized by white to cream semicircular basidiomata (usually arranged in tiers) with a granular to slightly spiny sterile upper surface, a fertile under surface with 10–15 mm long pointed spines, and ellipsoid to subglobose basidiospores. Morphological characters and DNA sequence analyses inferred from the nuclear ribosomal internal transcribed spacer region (nrITS) confirm the identity of the taxon.
