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.

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.

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.

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.

During survey on rock-inhabiting fungi from karst habitats in Guizhou, China, two new species in Cyphellophora were discovered and identified. Phylogenetic analysis based on combined sequences of the nuclear large subunit (nucLSU) and internal transcribed spacer (ITS) region of ribosomal DNA revealed that the tested isolates, clustered into two clades that well affiliated in the genus of Cyphellophora. Morphological characteristics were also supported the estabolishment of the new species. Herewith Cyphellophora botryose sp. nov. and Cyphellophora guizhouensis sp. nov. were described and their differences from closely related species were discussed.

Antrodia uzbekistanica sp. nov. is described and illustrated from juniper trees in Uzbekistan based on morphological characters and molecular evidence. It is characterized by producing annual, resupinate basidiome with large pores (1–2 per mm), a dimitic hyphal structure with clamp connections on generative hyphae, hyaline, thin-walled and cylindric basidiospores (6.5–8 × 2.7–3 µm), the presence of thick-walled and cyanophilous chlamydospores, and by causing a typical brown rot of Juniperus seravschanica in arid and semi-arid regions of Uzbekistan. The new species resembles Antrodia sinuosa macroscopically, but this species differs by having smaller basidiospores (4–6 × 1–2 µm), lacking of chlamydospores, and growing on wood of Pinaceae species. In nuclear large subunit rDNA (nLSU) and internal transcribed spacer (ITS) based phylogenies, the new species formed a distinct lineage in the Antrodia clade, and it is closely related to A. juniperina, which differs by having perennial, effused-reflexed basidiome with nodulose or round edged pilei, daedaleoid to labyrinthine pores, and larger and narrowly ellipsoid basidiospores (6.5–9 × 2.5–3.5 µm).

AbstractHirschmanniella santarosae sp. n. is described from the largest vernal pool in the Santa Rosa Plateau Ecological Reserve, Murrieta, California, USA. The cryptic new species is morphologically very close to H. pomponiensis and H. gracilis as it can be distinguished from the former only by a more anterior excretory pore position and by more flattened as well as laterally expanded stylet knobs, whilst it differs from the latter in the greater distance from phasmid to tail tip and in the bursal alae ending near the phasmids rather than near the tail tip. Analysis of the rDNA small subunit (SSU) and D2D3 expansion segments of the large subunit (LSU) shows that H. santarosae sp. n. is genetically distinct, having respective sequence homology of 98.89% and 95.9% with H. pomponiensis for these loci. Congruence in SSU and D2D3 gene trees as well as unambiguous character autapomorphies further support the new species status of H. santarosae sp. n. and sibling relationship with H. pomponiensis. Although many more isolates and species will need to be studied before informative biogeographic analyses can be performed, the presently available sequence data suggest that some Hirschmanniella lineages have diversified independently on either side of the Atlantic.

A New Species

A new species ofPaurodontella,P. persican. sp., collected from the Alborz rangelands of Iran, is described and illustrated. The new species is characterised by its body length of 506 (416-599) μm and 424 (388-461) μm in female and male, respectively, four incisures in lateral field, lip region annulated and continuous with body contour, total stylet 6.2 (5.5-7.0) μm long. Basal pharyngeal bulb with small posterior extension projecting reaching to the intestine. Excretory pore situated at the level of basal pharyngeal bulb region. Post-uterine sac short, 4.5 (3.0-6.0) μm long and uterus with an offset diverticulum. Tail of both sexes similar, conoid pointed, terminus tapering into a long pointed mucron. Male with adanal bursa and spicules 16.5 (16.0-17.0) μm long. The new species comes close in morphology and morphometrics to four known species of the genus, namelyP. auriculata,P. myceliophaga,P. minutaandP. niger. Molecular analyses of the partial small subunit rDNA gene (SSU), D2-D3 expansion segments of the large subunit rDNA gene (LSU) and internal transcribed spacer (ITS) revealed this to be a new species.
