A novel ascomycetous genus, Elongaticollum, occurring on leaf litter of Hedychium coronarium (Zingiberaceae) in Taiwan, is described and illustrated. Elongaticollum is characterized by dark brown to black, superficial, obpyriform, pycnidial conidiomata with a distinct elongate neck, and oval to oblong, hyaline, aseptate conidia. Phylogenetic analyses (maximum likelihood, maximum parsimony and Bayesian) of combined ITS, LSU, SSU and tef1-α sequence data revealed Elongaticollum as a distinct genus within the family Phaeosphaeriaceae with high statistical support. In addition, Ophiosphaerella taiwanensis and Phaeosphaeriopsis beaucarneae are described as new species from dead leaves of Agave tequilana and Beaucarnea recurvata (Asparagaceae), respectively. Neosetophoma poaceicola is reported as a new host record from dead leaves of Musa acuminata (Musaceae). Newly described taxa are compared with other similar species and comprehensive descriptions and micrographs are provided.

Marinophialophora garethjonesii sp. nov., representing a novel genus Marinophialophora gen. nov., associated with the basidiomycete fungus, Halocyphina on mangrove wood from Phetchaburi, Thailand, is described and illustrated. Marinophialophora morphologically resembles Phialophora and Junctospora (Herpotrichiellaceae, Chaetothyriales) in having macronematous, unbranched or branched conidiophores, globose to subglobose, solitary, acrogenous, pale to subhyaline, aseptate, conidia in chains and phialidic conidiogenous cells. Marinophialophora mainly differs from other related genera due to its conidia borne in basipetally developing branched chains and septate conidiophores. Phylogenetic analyses of a combined ITS, LSU and SSU sequence data show that Marinophialophora garethjonesii constitutes an independent lineage with high statistical support basal to the genus Exophiala within the family Herpotrichiellaceae (Chaetothyriales). The new marine taxon is described herein with illustrations and relationships inferred from DNA sequence data.

New Host Record

Collections of fungal samples from two dead leaf specimens from Italy were subjected to morphological examination and phylogenetic analyses. Two coelomycetous taxa belonging to two different genera in Xylariomycetidae, Sordariomycetes, namely Discosia and Sporocadus, were identified. The Discosia taxon is revealed as a new species and is herein introduced as Discosia ravennicasp. nov. while the Sporocadus taxon is identified as Sporocadus rosigena. Multi-locus phylogeny based on DNA sequence data of the large subunit (LSU) and internal transcribed spacer (ITS) of nuclear ribosomal genes, β-tubulin (β-tub) and RNA polymerase II second largest subunit (rpb2) showed that D. ravennica is related to D. neofraxinea but it forms an independent lineage that supports its new species status. The new taxon also differs from other Discosia species by its unilocular to bilocular, superficial and applanate conidiomata with basal stroma composed of cells of textura angularis, elongate-ampulliform conidiogenous cells and conidia smaller in size. Sporocadus rosigena is here reported as a new host record from Quercus ilex from Italy. Descriptions, illustrations and molecular data for both species are provided in this paper.

A novel species, Micropeltis goniothalamicola and a new record Scolecopeltidium menglaense were collected from Mae Fah Luang Botanical Gardens, Thailand. Our new taxon is different from other species in Micropeltis in having relatively smaller ascomata, 6–8-spored asci and 4–5-septate ascospores covering with mucilaginous sheath. Our new record, S. menglaense is the first host recorded from Jasmine grandiflorum (Oleaceae). Morphological comparison coupled with phylogenetic analysis of combined LSU and ITS sequence data provide evidence for the new species and new host record.

In the state of Rio Grande do Sul, there are few records of geographical distribution and host plants to species of Tomoplagia Coquillett, as well as other genera of Tephritidae, especially those associated with plants of the family Asteraceae. Here, we report the first occurrence of Tomoplagia rudolphi (Lutz & Lima, 1918) in the state of Rio Grande do Sul, inducing stem galls in Vernonanthura tweediana (Baker) H. Rob. (Asteraceae, Vernonieae), whose plant becomes a new host record for this species. In this way, is increased to nine species of Tomoplagia recorded for Rio Grande do Sul. Biological and morphological data and photos of gall, larvae, pupae at new host and distribution map of the species in Brazil are provided.

Ophiocordyceps is entomopathogenic and the largest studied genus in the family Ophiocordycipitaceae. Many species in this genus have been reported from Thailand. The first new species introduced in this paper, Ophiocordycepsglobiceps, differs from other species based on its smaller perithecia, shorter asci and secondary ascospores and additionally, in parasitising fly species. Phylogenetic analyses of combined LSU, SSU, ITS, TEF1α and RPB1 sequence data indicate that O.globiceps forms a distinct lineage within the genus Ophiocordyceps as a new species. The second new species, Ophiocordycepssporangifera, is distinguished from closely related species by infecting larvae of insects (Coleoptera, Elateridae) and by producing white to brown sporangia, longer secondary synnemata and shorter primary and secondary phialides. We introduce O.sporangifera based on its significant morphological differences from other similar species, even though phylogenetic distinction is not well-supported.

Modified and/or new keys to the four subfamilies now recognized within the Megaperidae Manter, 1934 n. comb. (Syn. Apocreadiidae Skrjabin, 1942) as well as the genera within each subfamily are presented. Two new genera, Paraschistorchis n. gen. and Plesioschistorchis n. gen., both within the Schistorchiinae Yamaguti, 1942, are erected and keys are provided to the species considered in both new genera—distinguished by possessing caeca that end either in separate ani or blindly. Plesioschistorchis callyodontis (Yamaguti, 1942) n. comb. and Plesioschistorchis haridis (Nagaty, 1957) n. comb. are re-described from new material collected from the common parrotfish, Scarus psittacus Forsskål (Perciformes: Scaridae), inhabiting the Red Sea off Egypt; S. psittacus represents a new host record for both species. The taxonomic status of Schistorchis sensu stricto Lühe, 1906 is examined and revised, a key to the four species we consider in this genus offered, and the monotypic genus Megacreadium Nagaty, 1956 declared a junior synonym of Schistorchis. Members of Schistorchis sensu stricto possess a unique “complex” (i.e. highly cellular/glandular) instead of “simple” (i.e. entirely muscular) type of oral sucker that is quite large in relation to body size; an elongate, somewhat sub-rectangular-shaped body; 5+ testes arranged in at least two rows; caeca that open via separate ani; a long post-testicular region; a median genital pore either at the anterior margin of or just anterior to the ventral sucker; and species of Schistorchis sensu stricto parasitize the intestine of marine fish within the Order Tetraodontiformes Berg. With the revision of this genus, we re-describe Schistorchis carneus Lühe, 1906 from the lower and mid-intestine of the white-spotted puffer, Arothron hispidus (Linnaeus) (Tetraodontiformes: Tetraodontidae), collected in the Red Sea off Egypt. Finally, a plea is made for further study of the Megaperidae n. comb. focusing, in particular, on the following: (1) obtaining new type/voucher materials of Plesioschistorchis manteri (Gupta & Tandon, 1984) n. comb. and Schistorchis paruchini Kurochkin, 1974; (2) elucidating the life histories (i.e. intermediate hosts) of members of the Postporinae Yamaguti, 1958 and Schistorchiinae; and (3) generating DNA sequence data for more species of megaperids to help future workers produce increasingly accurate taxonomic classifications that better reflect phylogenetic relationships within this ecologically diverse group of digeneans.

From Phoca vitulina richardi the following parasites are recorded: Corynosoma strumosum (Acanthocephala); Terranova decipiens and Contracaecum osculatum (Nematoda); Halarachne sp. (Acarina); Echinophthirius horridus (Anoplura). From Eumetopias jubata are recorded Diphyllobothrium pacificum, Diplogonoporus tetrapterus and Abothrium gadi (Cestoda); T. decipiens, C. osculatum and Parafilaroides sp. (Nematoda); Corynosoma villosum (Acanthocephala); Orthohalarachne diminuata (Acarina): Antarctophthirus microchir (Anoplura). E. jubata is probably not a true host of A. gadi, the parasite apparently being introduced by ingestion of infected fishes of the family Gadidae, the normal definitive hosts. Notes on host and geographical distribution, nomenclature and morphology of the parasites are included. Diphyllobothrium pacificum is a new combination for Adenocephalus pacificus. E. jubata is a new host record for D. pacificum, D. tetrapterus and O. diminuata. Several new geographical records are reported. The occurrence of larval stages of T. decipiens and C. strumosum in fishes is noted.

Morphological and molecular phylogenetic analyses of an entomogenous fungus associated with larvae of Lepidoptera in Guizhou and Anhui, China showed it to be a new species, Metacordyceps neogunnii. It differs from similar species in having longer asci and wider ascospores. Multigene analysis of ITS, 18S, TEF1 and RPB1 sequence data also confirmed the distinctiveness of this species. This species has been wrongly regarded in China as ‘Cordyceps gunnii’ for more than 30 years. Cordyceps gunnii from Tasmania is considered to be in the family Ophiocordycipitaceae based on its multigene phylogeny and morphological analysis.
