A New Species

Two species of Parasola, P. parvula sp. nov. and P. lilatincta are described from Kerala State, India, based on both morphology and molecular phylogeny. Descriptions with photographs of both the basidiocarps and the micro-structures and comparison with morphologically similar and phylogenetically related species are provided. Sequences of both the nuclear ribosomal internal transcribed spacer region (ITS) and the nuclear ribosomal large subunit (nLSU) region of the two species were obtained and used in BLASTn searches. Phylogenetic study was based on Maximum likelihood (ML) analysis of the ITS sequences.

A New Species

Three species of Clitopilus, C. albidus sp. nov., C. subscyphoides and C. orientalis, are described from Kerala State, India, based on morphology and molecular phylogeny. Comprehensive descriptions, photographs, and comparisons with phenetically similar and phylogenetically related species are provided. The RNA polymerase II genes (rpb2) of the three species were sequenced and analyzed. In addition, the nuclear ribosomal internal transcribed spacer regions (ITS) and the nuclear ribosomal large subunit (nLSU) genes were sequenced and used in BLAST searches to find similar sequences. Phylogenetic analyses based on rpb2 sequences performed using both Maximum Likelihood (ML) and Bayesian Analysis (BA) methods supported the novelty of C. albidus and its placement within the genus Clitopilus. C. subscyphoides and C. orientalis are the first and second record respectively of these species from India.

AbstractThe present paper describes the taxonomy of two new monogeneans, namely, Thaparocleidus longiphallus sp. n. and T. siloniansis sp. n., based on morphological, morphometric and molecular biological analysis, collected from the fish Wallago attu (Bloch & Schn.) and Silonia silondia (Ham.), respectively, at Meerut, UP, India. Genetic characterization of the two new species is based on sequence analyses of the rDNA 28S gene using neighbour-joining and maximum-parsimony techniques. These methods are congruent in depicting T. longiphallus sp. n. and T. siloniansis sp. n. as closely related species, but distinct from each other and forming a subclade with other species of the genus Thaparocleidus Jain, 1952. Secondary-structure models of the large subunit rDNA of the two species were also predicted using a combined comparative and thermodynamic approach. Molecular morphometric and phylogenetic relationships of the isolates of the Thaparocleidus species are discussed in detail.

Three new species of Russulaceae, Lactifluus umbonatus and Lactifluus indicus belonging to Lf. subg. Gerardii and Lactarius keralensis belonging to L. subg. Piperites, are described from Kerala State, India. Comprehensive descriptions, photographs, line drawings and comparisons with phenetically similar and phylogenetically related species are given. Nuclear ribosomal internal transcribed spacer regions (ITS) of the three species were sequenced and analyzed. In addition, nuclear ribosomal large subunit (nLSU) gene of Lactifluus indicus was sequenced and the sequence was used in BLASTn search to find similar sequences. Maximum likelihood (ML) analysis based on the ITS sequences confirmed both the novelty of these species and their placement within their respective genera. The discovery of Lactifluus umbonatus and Lf. indicus represent the first report of novel species belonging to Lf. subg. Gerardii from India. Lactifluus indicus represents the second record of a pleurotoid Lactifluus species from India.

A New Species

Plectania lutea, is described as a new species from subtropical karst areas of China. The main distinguishing characteristics of P. lutea are the yellow hymenium, the external surface with ridges, the gelatinous but not semifluid medullary excipulum, and the large finely warted ascospores. The phylogenetic analyses based on internal transcribed spacer (ITS) and the large subunit (LSU) regions of rDNA sequences using Bayesian (BA) and Maximum Likelihood (ML) methods showed that the new taxon can be distinguished from phenotypically similar and phylogenetically related species.

Two fresh collections of Discosia were made from dead leaves of Fagus sylvatica in Italy. As these collections could not be cultured, the fruiting bodies were directly used for sequencing using a Forensic DNA Extraction Kit. Based on analyses of the concatenated internal transcribed spacer regions of the nrDNA operon (ITS) and large subunit rDNA (LSU) gene sequences, as well as morphological characters, the fresh collections are introduced as two new species, namely D. italica and D. fagi. Phylogenetically, these two species are distinct from all other Discosia species. Morphologically, D. italica is somewhat similar with D. fagi, but can be distinguished using dimension of conidiomata and conidiogenous cells. Descriptions and illustrations of the new taxa are provided herein.

Tubaria keralensis sp. nov. is described from Kerala State, India based on morphology and molecular phylogeny. Comprehensive description, photographs, and comparisons with phenetically similar and phylogenetically related species are provided. Tubaria keralensis is characterized by its strongly intervenose lamellae with concolorous edges; a stipe with velar remnants and a white, strigose basal mycelium and broadly ellipsoid to ovoid basidiospores. Nuclear ribosomal internal transcribed spacer region (nrITS) and nuclear ribosomal large subunit (nrLSU) gene region were sequenced and analyzed. Maximum likelihood (ML) analysis of combined nrITS and nrLSU sequence data revealed the novelty of the species as well as its placement in the T. furfuracea complex. The present discovery of T. keralensis forms the second report of a new Tubaria species from Kerala.

Key Characters

Two new species of Calocybe (Calocybe erminea sp. nov. and C. badiofloccosa sp. nov.) are described from Liaoning province, China. Calocybe erminea is characterized mainly by its light khaki to dirty white pileus, slightly hygrophanous stipe, small basidiospores and cellular epicutis. The key characters of C. badiofloccosa are its light ocher yellow and rough pileus, villose stipe and large basidiospores. The results of phylogenetic analyses based on the internal transcribed spacer (ITS) and the nuclear large subunit rDNA (nrLSU) region indicated that they belong to Calocybe, but they are distinct from other species in the genus. They are compared morphologically with other species which are phenotypically similar and the phylogenetic relationships between them and allied taxa are discussed. These results confirm the species is new to science.

Two new species of Fergusobia, collected from small multilocular axillary vegetative bud ('stem') and unilocular leaf 'pea' galls on, respectively, Eucalyptus camaldulensis from South Australia, and an unknown species of Corymbia growing in sub-coastal north-eastern NSW, Australia, are described. Fergusobia camaldulensae n. sp. Davies is characterized morphologically by an almost straight to open-C shaped parthenogenetic female with a broadly conoid tail, an arcuate infective female with a hemispherical tail tip, and males of varying shape with weakly sclerotised angular spicules and bursa arising at mid-body length. Fergusobia rileyi n. sp. Davies is characterized morphologically by the combination of an almost straight to arcuate parthenogenetic female with a broadly conoid tail, an arcuate infective female with relatively narrow tail with a pointed tip, and arcuate males with arcuate spicules, a relatively slender tail, and long peloderan bursa. These species are associated with larvae of undescribed fly species having dorsal shields of the 'transverse bars' form or lacking. Other apparently related forms of Fergusobia/Fergusonina associations from small 'stem' and 'shoot' galls and unilocular leaf 'pea' galls are reported, the larval shield morphology of their associated mutualistic fly species is discussed where known, and their possible relationships are outlined. DNA sequence analyses of the domain 2 and 3 segments of the large subunit rDNA gene (D2/D3) and mitochondrial DNA cytochrome oxidase subunit 1 (mtCOI) supported the new species status and their phylogenetic relationships with other sequenced species in Fergusobia.
