A new smut fungus, Entyloma eranthidis on Eranthis longistipitata from Uzbekistan, revealed by molecular, morphological, and ecological evidence, is described and illustrated. It differs from all other species of Entyloma by host specialization on Eranthis and by having longer (≤35(–38) μm) spores and thicker (≤10(–12) μm) spore walls. ITS rDNA sequence analysis indicates that the new species does not cluster with other species of Entyloma on Ranunculaceae.

A New Species

Knowledge on the diversity of hypogeous sequestrate ascomycetes is still limited in the Balkan Peninsula. A new species of truffle, Tuberpulchrosporum, is described from Greece and Bulgaria. Specimens were collected from habitats dominated by various oak species (i.e. Quercusilex, Q.coccifera, Q.robur) and other angiosperms. They are morphologically characterised by subglobose, ovoid to irregularly lobed, yellowish-brown to dark brown ascomata, usually with a shallow basal cavity and surface with fissures and small, dense, almost flat, trihedral to polyhedral warts. Ascospores are ellipsoid to subfusiform, uniquely ornamented, crested to incompletely reticulate and are produced in (1–)2–8-spored asci. Hair-like, hyaline to light yellow hyphae protrude from the peridium surface. According to the outcome of ITS rDNA sequence analysis, this species forms a distinct well-supported group in the Aestivum clade, with T.panniferum being the closest phylogenetic taxon.

A new species, Roseodiscus sinicus is described and illustrated. The fungus, collected on stems of an unknown monocotyledon, is characterized by dirty white apothecia, large and thin-walled ectal excipulum cells, Calycina-type ascus apical ring, and ellipsoid, multiguttulate ascospores. The placement of the new species in Roseodiscus was also supported by ITS rDNA sequence analysis. The distinctions between the new species and related taxa are discussed.

Two specimens of Mucor variicolumellatus L. Wagner & G. Walther were isolated from soil samples collected in an upland rainforest area located in Pernambuco state, Brazil. Their identity were confirmed by morphophysiology and ITS rDNA sequence analysis. Both specimens are distinguished from other species within the Mucor circinelloides complex by producing obovoid, ovate and strawberry-shaped columellae. A detailed description and illustration of the specimens are presented. This is the first record of M. variicolumellatus in the Neotropics.

During a study on filamentous fungi in the soil of mountainous environments in the state of Minas Gerais, Brazil, one specimen of Mortierella verticillata Linnem. was isolated. Fungal identity was confirmed by morphology and ITS rDNA sequence analysis. This study reports the first occurrence of M. verticillata in South America. This species is distinguished by its monopodial sporangiophores growing on aerial hyphae of verticillate branches, and single-spored sporangia finely ornamented with a diffluent wall. In this manuscript, the specimen is described and illustrated, and the distribution of this species is discussed.

A new smut fungus, Sporisorium capillipedii-alpini (Ustilaginales), and a new species of grass, Capillipedium alpinum (Poaceae), on which it is growing, are described and illustrated. The collections were made in western Sichuan, China. Capillipedium alpinum differs from other species of Capillipedium by its diminutive size and short, slender inflorescence. Sporisorium capillipedii-alpini is compared with the species of Sporisorium with similar symptoms (destroying all spikelets of an inflorescence) that infect Capillipedium, Botriochloa, and Dichanthium. The new smut fungus differs from these species as follows: from Sporisorium taianum by having larger spores with minutely echinulate spore walls, from S. dichanthicola by having larger spores, from S. sahayae by having lower spore wall ornamentation and thinner spore walls, from S. andropogonis-annulati by having larger spores, and smaller sterile cells with thinner walls, and from S. mysorense by possessing minutely echinulate spore walls and differently colored spores and sterile cells. The types of S. andropogonis-annulati, S. mysorense, and S. sahayae were re-examined and detailed descriptions of these species are given. A key to the smut fungi of Sporisorium, that infect Capillipedium, Botriochloa, and Dichanthium and destroy all spikelets of the inflorescence of an infected plant, is also provided.

Setomelanomma holmii M. Morelet, previously known only from the type specimen in France, was discovered in the U.S.A. (Kansas and Wisconsin) and Canada (Ontario) on living twigs of spruce (Picea pungens and Picea glauca). This fungus was grown from ascospores and compared with the ex-holotype culture. Morphology and ITS rDNA sequence similarities indicate that S. holmii belongs in the Pleosporales, Phaeosphaeriaceae. Sequence analysis of the SSU nrDNA places S. holmii in a clade containing members of the Leptosphaeriaceae and Phaeosphaeriaceae. Setomelanomma holmii is redescribed and illustrated based on the holotype and North American specimens.Key words: Loculoascomycetes, Phaeosphaeriaceae, Picea, Pleosporales, needle chlorosis.
