Loose Ends in the Cortinarius Phylogeny: Five New Myxotelamonoid Species Indicate a High Diversity of These Ectomycorrhizal Fungi with South American Nothofagaceae

This paper is a contribution to the current knowledge of taxonomy, ecology and distribution of South American Cortinarius (Pers.) Gray. Cortinarius is among the most widely distributed and species-rich basidiomycete genera occurring with South American Nothofagaceae and species are found in many distinct habitats, including shrublands and forests. Due to their ectomycorrhizal role, Cortinarius species are critical for nutrient cycling in forests, especially at higher latitudes. Some species have also been reported as edible fungi with high nutritional quality. Our aim is to unravel the taxonomy of selected Cortinarius belonging to phlegmacioid and myxotelamonioid species based on morphological and molecular data. After widely sampling Cortinarius specimens in Patagonian Nothofagaceae forests and comparing them to reference collections (including holotypes), we propose five new species of Cortinarius in this work. Phylogenetic analyses of concatenated rDNA ITS-LSU and RPB1 sequences failed to place these new species into known Cortinarius sections or lineages. These findings highlight our knowledge gaps regarding the fungal diversity of South American Nothofagaceae forests. Due to the high diversity of endemic Patagonian taxa, it is clear that the South American Cortinarius diversity needs to be discovered and described in order to understand the evolutionary history of Cortinarius on a global scale.

Species Descriptions

Mushrooms with a thin-fleshed pileus that becomes plicate on opening, deliquescent lamellae and dark brown to blackish basidiospores are commonly called coprinoid mushrooms. The genusCoprinellusis one of the important lineages of coprinoid mushroom in the family Psathyrellaceae. Species-level taxonomy inCoprinellusis based mainly on the presence or absence and the structure of veil and cystidia on the pileus, of cystidia on the lamellae and on basidiospore morphology. In this study, four new species ofCoprinellus(Co.campanulatus,Co.disseminatus-similis,Co.pakistanicusandCo.tenuis) are described from Pakistan. Species descriptions are based on morphological and molecular data. Phylogenetic analyses based on nuc rDNA ITS region show that the new speciesCo.campanulatusandCo.disseminatus-similisare clustered in a clade including members of section Micacei;Co.tenuisfalls in a clade with members of section Domestici; andCo.pakistanicusrecovered in a separate clade adjacent to other recently described clades of genusCoprinellus. Morpho-anatomical descriptions of the new species and comparison with closely allied taxa are provided. With this study, the number of known species ofCoprinellusin Pakistan has reached eight.

Morphological And Molecular Data

Parasola is a genus of small, veil-less coprinoid mushrooms in the family Psathyrellaceae (Agaricales). The genus is not well documented in Asia, specifically in Pakistan. In this study we describe two new species Parasolaglabra and P.pseudolactea from Pakistan, based on morphological and molecular data. Phylogeny based on three DNA regions: nuc rDNA region encompassing the internal transcribed spacers 1 and 2 along with the 5.8S rDNA (ITS), nuc 28S rDNA D1-D2 domains (28S) and translation elongation factor 1α gene (TEF1α) show that the new taxa are clustered in a clade formed by the members of section Parasola of genus Parasola. Parasolaglabra with grayish pileus, slightly depressed pileal disc, lamellae separated from the stipe by pseudocollarium, basidiospores 14.5–16.5 × 9.5–11.5 × 8.0–10.5 µm, in front view broadly ovoid to oblong, some with rhomboidal outline, in side view ellipsoid, with eccentric germ-pore of 1.5 µm diameter. Parasolapseudolactea with yellowish brown to dull brown pileus, disc indistinctly umbonate, lamellae free, pseudocollarium absent, basidiospores 13.5–14.5 × 10.5–12.0 × 9.5–10.5 µm, in face view rounded triangular to heart shaped, rarely ovoid to subglobose, in side view ellipsoid to oblong, with eccentric germ-pore of 1.5 µm diam. In addition to these new species, P.auricoma and P.lilatincta were also studied. Morphological descriptions for the new species and comparison with known Parasola species are provided. Our observations highlight the diversity of Parasola in northern Pakistan and further document the need for additional systematic focus on the region’s fungi.

Morphological And Molecular Data

Abstract Dacrymycetes has four families and 13 genera, few of them with molecular data available and then usually polyphyletic in phylogenetic analyses. Dacrymyces Nees is one of the polyphyletic genera in Dacrymycetes and it was introduced to accommodate one species, D. stillatus Nees. The morphological features of the genus are a homogeneous composition of the intra-structure and an amphigenous or superior hymenium. In this study, we included Neotropical specimens in the phylogeny of the Dacrymycetes and Dacrymyces s.s. is emended to include species with resupinate basidiomata, unilateral hymenium and heterogeneous context. In this new delimitation, the new species Dacrymyces flavobrunneus is described using morphological and molecular data and three new combinations (D. ceraceus comb. nov., D. maxidorii comb. nov. and D. spathularia comb. nov.) are proposed based on DNA analyses.

Taxonomic System

Agaricus is a species-rich genus with more than 500 species over the world. Recent studies on tropical Agaricus revealed new tropical clades and a revised taxonomic system was consequently developed. Agaricus subg. Minoriopsis, a sixth subgenus was recently added, comprising species exclusively from the Americas. The diversity of Agaricus is little studied in Mexico, despite this country has a long history in the consumption of wild edible fungi. In this paper, we introduce a new species A. guzmanii and a new record for A. globocystidiatus from Mexico based on morphological characteristics and molecular data. Phylogenetic analyses indicate that they belong to A. subg. Minoriopsis.

A New Species

Based on field investigations, morphological and molecular systematic studies, a new species, Caltha dysosmoides (Ranunculaceae) from southwestern China is described. It differs from all other known congeneric species by the densely dentate leaf margin, the pendulous pedicels, the scarlet flowers, the compressed filaments, and the triangular connective. To better understand taxonomy of this new species, phylogenetic analyses were conducted using a combined dataset from nrITS, plastid trnL-trnF region, and atpB-rbcL spacer. The results indicate that Caltha is monophyletic and C. dysosmoides is sister to C. sinogracilis. The conservation status of the new species is categorized as CR based on IUCN criteria.

AbstractA new species of the plantbug genus Dicyphus (Insecta: Heteroptera: Miridae), D. umbertae Sanchez & Cassis sp. n., from Portugal is described and the closely related species, Dicyphus cerastii Wagner is redescribed. Several body measurements were taken. Male and female genitalia of both species are illustrated. D. umbertae was found in several localities in Central and South of Portugal on tomato (Lycopersicon esculentum Mill.) and Hyosciamus albus L. D. cerastii was found in southeast Spain on squash (Cucurbita maxima Duchesne), L. esculentum, Ononis natrix L., Withania frutescens (L.) Pauquy and H. albus. The external morphology of the two species is very alike and measurements overlap. In the two species the aedeagus has a similar pair of prominent slightly arcuate sclerites, but the shape and setae on the left paramere are different. Phylogenetic analyses were performed using 381 bp fragments of Cytochrome b. Other dicyphine species were used as outgroups in the analyses: Dicyphus tamaninii Wagner, D. rubicundus Blöte, D. escalerae Lindberg, Nesidiocoris tenuis (Reuter), Cyrtopeltis geniculata Fieber and Macrolophus sp. Several evolutionary models were explored under a maximum likelihood framework. The molecular analyses provided strong support for the species identity of the two sister species D. umbertae and D. cerastii.

A New Species

This study describes a new orchid species, Cymbidium motuoense, from Xizang, China based on morphological and molecular analyses. Several unique morphological features distinguish this new orchid from all other species of Cymbidium. Based on its morphology, this orchid is similar to C. tracyanum but differs in its yellow-green flower with dark purple-red spots on the veins, oblong-elliptic sepals, side lobes of the lip with reddish brown hairs along the veins and disc with three purple-red lamellae. Phylogenetic analyses based on plastid DNA (matK and rbcL) supported C. motuoense as a new species. However, the low support in nuclear ribosomal ITS tree provide the possibility that the new orchid may be a natural hybrid of C. tracyanum and C. iridioides or another closely related species.

The systematics of the characid genus Tetragonopterus is reviewed based on morphological and molecular data of specimens from its entire geographical range encompassing all major South American river drainages from Orinoco basin southward to the La Plata basin. Eight previously described species (T. anostomus, T. araguaiensis, T. argenteus, T. carvalhoi, T. chalceus, T. denticulatus, T. georgiae n. comb., and T. rarus) are recognized as valid, four of which are redescribed (T. argenteus, T. chalceus, T. georgiae, and T. rarus), and four new species from the Brazilian Shield in the Amazon and São Francisco river basins are herein described. We also provide evidence for the reallocation of Moenkhausia georgiae into Tetragonopterus and recognize T. akamai as junior synonym of T. anostomus. DNA barcodes of Tetragonopterus revealed genetic support for each recognized species and provided valuable population-level information within T. argenteus, T. chalceus, T. georgiae, and T. rarus.
