A New Species

Pseudocercospora haldinae, a new anamorphic foliicolous hyphomycetous fungus discovered on living leaves of Haldina cordifolia (Rubiaceae) is taxonomically described and illustrated. This species is compared with closely related species of Pseudocercospora and other dematiaceous cercosporoid forms reported on the same host genus. The phylogeny of this species has been inferred from partial nuclear ribosomal 28S large subunit (LSU) and complete internal transcribed spacer (ITS) rDNA sequence data. On the basis of LSU, P. haldinae represents characteristic features of Pseudocercospora s. str. and did not form red crystals when cultivated on agar media.

Podosphaera thermopsidicola, a new sexual morph form of powdery mildew was discovered on living leaves of Thermopsis barbata Benth. (Fabaceae). It is described, illustrated and compared with other Podosphaera species reported on Fabaceae. The phylogeny of this species has been inferred from partial nuclear ribosomal 28S large subunit (LSU) and internal transcribed spacer (ITS) rDNA sequence data. On the basis of LSU, P. thermopsidicola represents characteristic feature of Podosphaera s. str. Phylogenetically, P. thermopsidicola is closer to P. erigerontis-canadensis but differs in having larger chasmothecia, longer appendages, thick-walled asci, smaller oculi and smaller ascospores.

A New Species

A new species of Amanita subgenus Amanita sect. Vaginatae is described and illustrated based on material collected in pine forests in district Mansehra, Khyber Pakhtoonkhaw, Pakistan. Amanita mansehraensis is recognized by the presence of a light brown or light greyish olive pileus with strong brown or deep brown pileus center; non-appendiculate, rimose, sulcate or plicate striate pileus margin; subglobose to ellipsoid basidiospores; and a saccate volva. The internal transcribed spacer region (ITS) and large subunit of the nuclear ribosomal RNA gene (nrLSU) were used for the delimitation of this species based on sequence data. The evolutionary relationships of A. mansehraensis with other species of Amanita were inferred by means of Maximum Likelihood and Bayesian inferences of the nrLSU dataset and concatenated ITS+nrLSU dataset. Amanita mansehraensis is most closely related to A. brunneofuliginea, A. pseudovaginata, and the recently described A. glarea.

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.

Pseudocercospora hamiltoniani, a new asexual foliicolous hyphomycetous fungus was discovered on living leaves of Euonymus hamiltonianus (Celastraceae) is described and illustrated. This species is compared with closely related species of Pseudocercospora and other cercosporoid forms reported on the same host genus. The phylogeny of this species has been inferred from internal transcribed spacer (ITS). Phylogenetically, Ps. hamiltoniani differ from closely related Ps. ranjita in having smooth to verruculose mycelium; mostly solitary, highly septate, smooth to verruculose, longer and thicker conidiophores and highly septate with oblique septation, presence of rounded cells, smooth to verruculose, longer and thicker conidia.

Podosphaera filipendulensis, a new teleomorph of powdery mildew was discovered on living leaves of Filipendula vestita (Rosaceae). It is the first species of powdery mildew that causes wilting and ultimately death of apical infected leaves of F. vestita. It is described, illustrated and compared with other Podosphaera species reported on Rosaceae and a key to all species reported on Rosaceae is provided. The phylogeny of this species has been inferred from internal transcribed spacer (ITS) rDNA sequence data. Phylogenetically, P. filipendulensis is close to P. ferruginea var. ferruginea and P. macularis but differs in having larger chasmothecia, smaller peridium cells, shorter, narrower and aseptate appendages, 8-spored asci and smaller ascospores.

A new species, namely Chlorociboria herbicola, is discovered on herbaceous stems in central China. Morphologically, the new fungus is distinctive by the combination of light blue-green apothecia, rectangular cells in ectal excipulum, and elongate-ellipsoidal ascospores with rounded ends. Phylogenetic analyses of the internal transcribed spacer and large subunit of nuclear ribosomal DNA sequences confirm its ascription in Chlorociboria and distinction from the known species of the genus.

AbstractA new entomopathogenic nematode in the genus Heterorhabditis is described from South Africa, from two singular isolates found 1000 km from each other, from beneath a fig tree and in a citrus orchard, respectively. Morphological and molecular studies indicate both isolates to be the same and a new undescribed Heterorhabditis species. Comparison of sequences of the internal transcribed spacer (ITS) rDNA and the D2D3 region of the 28S rDNA gene with available sequences of other described species within the genus, indicate the two isolates as a new species. Phylogenetic analysis of the sequence data concerned placed the new species, H. noenieputensis n. sp., closest to H. indica and H. gerrardi in the indica-group. The new species, H. noenieputensis n. sp., is distinguished from other species in the genus by a combination of several morphological traits of the males and the infective juveniles (IJs). The new species differs from all other species previously described, as regards the body length of the IJs, except for H. indica and H. taysearae, in which the IJ is smaller. The IJ also differs from that of H. indica in the length of the oesophagus, the body diameter, the length of the tail and the E%. In addition, males of H. noenieputensis n. sp. differ from their closest relative, H. indica, in the position of the excretory pore, SW% and D%; and from H. gerrardi in the length of the oesophagus and SW%. The seventh pair of genital papillae of H. noenieputensis n. sp. are normally developed, while for H. indica they are often branched or swollen at the base, while 8 and 9 are usually absent in both species.
