Isolation of culturable yeasts from market wines and evaluation of the 5·8S-ITS rDNA sequence analysis for identification purposes

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 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.

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.

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.

Tulasnein (1), a new metabolite with strong antimicrobial and weaker cytotoxic and phytotoxic activity, was isolated from culture filtrates of three strains of the xylariaceous coprophilous fungus Podosordaria tulasnei. The producing strains were identified by their rhizomorphs and by ITS rDNA sequence analysis. A second new metabolite, podospirone (2), was also produced by all three strains whereas the weakly cytotoxic (+)-3,4-anhydroshikimic acid methyl ester (3) was detected in only one strain.

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.
