A new species, Lepiota elseae, is described from Mediterranean areas in Spain in association with Quercus ilex, based on both morphological and molecular characters (analysis of the ITS-rDNA sequences). Illustrations of fresh basidiomata in situ and of the main macro- and micromorphological features are provided. L. elseae belongs to section Lepiota and is compared with morphologically similar taxa. The phylogenetic relationship with related species based on ITS sequences is discussed.

Tremella laurisilvae, a species new to science with a parasitic strategy on Biscogniauxia species, is described from the evergreen laurel forests of Macaronesia. The basidiocarps are macroscopically differentiated by finger-like lobes and brown-orange colour. Micromorphological differences with phylogenetically related species are evaluated and its phylogenetic placement in Tremellomycetes is inferred from ITS rDNA sequences. A detailed description, plate with photographs and a key to species from Europe and Macaronesia are provided.

Xylaria fusispora, an undescribed species of Xylaria (Xylariales, Xylariaceae), is described and illustrated as a new species based on collections from Guizhou Province, China. Both morphology and phylogenetic analysis of nrDNA ITS sequences support the establishment of this new species. The fungus is characterized by its fusoid-equilateral ascospores and an ascus apical ring not bluing in Melzer’s reagent. The differences between the new species and the related fungi are discussed.

A New Species

A new species of truffle, T.aztecorum, is described from central Mexico. Tuberaztecorum can be distinguished from other related Tuber species synoptically by a combination of morphological features including ascospore size, pellis cells with irregular thickness, cystidia, ascoma colour and associated host (Abiesreligiosa an endemic Abies species from central Mexico); sequence variation on the ITS rDNA also distinguishes T.aztecorum from related species. A phylogenetic analysis of the ITS rDNA demonstrates that T.aztecorum belongs to the Maculatum clade and is unique from other similar small, white-cream coloured Tuber species distributed in north-eastern Mexico such as T.castilloi and T.guevarai.

Viola denizliensis is described as a new species from South-West Anatolia. The species grows on serpentinite stony slopes in Bozdağ Mountain in Denizli. It belongs to Viola sect. Melanium and is close to V. dirimliensis and V. kitaibeliana. Viola denizliensis can be readily distinguished from related species by morphological and molecular characters. Comments on descriptive and diagnostic characters, distribution and ecology, phenolgy and proposed conservation status for this new species are given in the present study. Morphological affinities and ISSR-based molecular relationships between V. denizliensis and related species are also discussed.

A New Species

Selected fungi on ferns in Taiwan are described, illustrated, annotated and complemented with first DNA sequences. The ranges of distribution, host species, morphology, and the taxonomy of some species were revised. ITS rDNA sequences proved to be useful for distinguishing between species on the same host. A new species of Venustosynnema found on dead leaves of Selaginella moellendorfii differs from the other species of the genus by its small conidiomata with smooth central seta and reniform conidia. A new species of Zasmidium described on living fronds of Dicranopteris linearis is particular by its hyaline, smooth conidia. New data are derived from new collections of Pseudocercospora athyrii, Ps. cyatheae, and Ps. pteridophytophila hitherto only known from the type collections and of Mycosphaerella gleicheniae. Ps. christellae is considered a synonym of Ps. pteridophytophila. M. gleicheniae and Ps. cyatheae are new records for Taiwan.

AbstractBacidina flavoleprosa is described as a new species from the Czech Republic. Its position within the genus is supported by phylogenetic inferences of ITS rDNA sequences from its holotype and many other representatives of Bacidia s. lat., including newly sequenced Bacidina sulphurella, B. adastra and B. neosquamulosa, as well as additional sequences of B. arnoldiana. ITS data also support the recent delimitation of B. arnoldiana and B. sulphurella based on the shape of conidia and ecological preferences.

A new poroid fungus, Nigrofomes submelanoporus, from tropical China, is described and illustrated based on morphological characteristics and phylogenetic analysis. The new species is characterized by perennial, resupinate to effused-reflexed, woody-hard and dark gray to almost black basidiocarps, lacerate dissepiments, a monomitic hyphal system, the presence of cystidioles and hyphal pegs, and broadly ellipsoid basidiospores (4–5.1 × 3.1–4.3 µm). Molecular analysis based on ITS sequences demonstrates the phylogenetic position of the new species in Nigrofomes. The discriminating characteristics between the new species and closely related species are discussed.

Chrysosphaerella rotundata sp. nov. is described from a small lake in Finland. Ultrastructural morphology of C. rotundata scales is similar, even identical, to the morphology of C. brevispina scales. However, C. rotundata possesses three types of scales: scales characterized by a circular or almost circular outline were found in addition to the larger and smaller oval scales. Significant genetic differences were recognized in ITS rDNA sequences between C. rotundata and C. brevispina. Results of the molecular analyses and the observed morphological variation of scales have been discussed, clearly showing the existence of a hidden diversity within the genus Chrysosphaerella.
