Key words: Myxomycota, biodiversity, Ukraine, East Forest-Steppe

Abstract: During the 2006–2008 summer–autumn seasons, the myxomycete biodiversity was investigated in Gomolsha Forests National Nature Park and neighbouring territories of the East Forest-Steppe area of Ukraine. Several earlier collections (2002-2004) were also reexamined. Four species found appeared to be new for Ukraine, six others were estimated as rare for the country. Descriptions, microphotographs, localities and information on substrata are presented for these species.

Key words: Archipelago Sea, Colacogloca peniophorae, corticioid fungi, Phlebia cremeoalutacea, Trechispora invisitata ssp. hauerslevi, Trechispora laevis

Abstract: Phlebia cremeoalutacea is reported as a corticioid fungus new to Finland. New records of Colacogloea peniophorae, Trechispora invisitata ssp. hauerslevi and Trechispora laevis are given. All these records were made in SW Finland, from the forested islands of the Archipelago Sea. Inventories were carried out between July and November 2008. As Phlebia cremeoalutacea is known to inhabit especially the hemiboreal zone and it has been found from all the other countries adjacent to Finland, its discovery can be considered as expected. The three other species are little collected, with less than five earlier records.

Key words: Hyaloscyphaceae, Hyaloscypha, Fuscoscypha, Betulina, Ureolella, bryophilous ascomycetes

Abstract: The monotypic genus Fuscoscypha possesses hairs similar as in the genusHyaloscypha but differs by grey-olivaceous-brown apothecia with short dark stipes. Molecular data proves that the pigmentation does not permit delimitation of a separate genus, as white and brown taxa do not form separate clades. Followingly, Fuscoscypha is here considered to be a synonym of Hyaloscypha. Three of the here treated four species have an olivaceous-brown excipulum. Two are saprophytes on decaying leaves and fruits of angiosperms: F. acicularum, the type species ofFuscoscypha, and Hyaloscypha fuscostipitata comb. nov. (formerly placed in Betulina). Two are biotrophic parasites on Bryophyta: Hyaloscypha hepaticola comb. nov. (formerly placed in Trichopeziza) and the hyaline-excipled Hyaloscypha albocarpa spec. nov. which is otherwise very similar to H. hepaticola. The type species of the genus Betulina, B. hirta, is found to be an earlier synonym of Urceolella salicicola (= U. graddonii) . The new combination Urceolella hirta is therefore proposed, hence Betulina is considered a synonym of Urceolella.

Key words: Lactarius, Lactarius aspideus, Lactarius flavidus, Fennoscandia, taxonomy

Abstract: Two new species with violet staining milk and related to Lactarius aspideus (Fr. : Fr.) Fr. are described from Fennoscandia: L. flavopalustris Kytöv., spec. nova and L. flavoaspideus Kytöv., spec. nova. The distribution of each species is mapped, and their taxonomy, ecology and relationships are discussed.

Key words: Swedish myxomycetes, Macbrideola, Physarum crateriforme, Stemonitopsis

Abstract: Eleven species of myxomycetes are formally reported from Sweden for the ?rst time,namely Collaria lurida, Cribraria persoonii, Diderma cinereum, Fuligo leviderma,Lamproderma pseudomaculatum, Physarum crateriforme, Stemonitis pallida, Stemonitopsis amoena, S. gracilis, S. subcaespitosa and Symphytocarpus impexus. A possibly undescribed species of Macbrideola is discussed and illustrated. New records of several rarely collected species are cited, among them Hemitrichia abietina, H. leiotricha andPhysarum diderma. The great variation of Physarum crateriforme in moist chamber cultures is discussed.

Key words: Ascomycetes, endoconidia, Finland, habitat, Melzer’s reagent, nomenclature, North America, Persoon, Pezizomycetes

Abstract: Three new species of Otidea (Pers.) Bonord. (Pyronemataceae, Pezizales) are described on the basis of Finnish material: Otidea angusta Harmaja, Otidea caeruleopruinosa Harmaja, and Otidea flavidobrunneola Harmaja. They were found in rich woods with more or less calcareous soils in SW Finland. A synopsis with an annotated list of the twenty species of Otidea in Finland is presented, four of the latter as nomina provisoria. The habitat of each species is described more accurately than previously. Two keys are presented, one based on macroscopic and habitat characters, the other on microscopic characters. The characters of the North American O. unicisa (Peck) Harmaja are discussed, the species is retained in the genus in spite of its ornamented spores, and it is reported as new to North Carolina. Two previously unreported responses of the pigment in the outer part of the apothecial excipulum to Melzer’s reagent are reported. The original material of C. H. Persoon’s species referable to Otidea has been revised: no changes in current nomenclature are needed. O. cantharella (Fr.) Quél. is considered to be an older name for O. caligata (Nyl.) Sacc.

Key words: Agaricales, Basidiomycetes, Finland, Inocybe, Salix, taxonomy

Abstract: Inocybe saliceticola, a new species of section Marginatae, is described from Finland. It is characterized by ochraceous pileus, bulbous stipe base and weakly nodulose spores. It grows with Salix in moist habitats. The holotypes of I. alnea, I. dunensis, I. obtusiuscula, I. ochracea and I. straminipes are treated. I. straminipes is reduced to a synonym of I. salicis. The synonymy of I. ochracea with I. alnea is supported by DNA analysis. The microscopical drawings of the type of I. obtusiuscula are given for the first time.

Abstract: During June–July 2008 the author visited Paraguay with the objective of collecting myxomycetes, and substrates from which they might be cultured. This resulted in a count of 73 species, bringing the total for the country to 90 species. A new species, Physarum minutum, is described.

Abstract: The new stipitate species of Hypocrea, H. seppoi; is described, based on material freshly collected in Finland. Characterization of this species includes morphology of teleomorph and anamorph, culture studies and molecular phylogeny. H. seppoiis compared to the other European soil-inhabiting, stipitate Hypocrea species. It is characterized by small stromata, thin fi brous stipe, perithecia decurrent on the stipe, and by conidia that are smaller than those of H. leucopus and H. nybergiana. In addition, this work confirms the congenerity of Podostroma and Podocrea withHypocrea on molecular phylogenetic grounds using sequences of the nuclear genes coding for RNA polymerase II subunit b (rpb2), translation elongation factor 1 alpha (tef1), and endochitinase (chi15-8).

Key words: Karstenellaceae, Pezizales, cytology, LSU, SSU

Abstract: Phylogenetic analyses of partial SSU and LSU rDNA sequences confirm that Karstenella vernalis is a member of the Pezizales. Substantiating this, we definitively report that the asci of Karstenella are operculate. Karstenella vernalis has been reported only from the type locality in Finland; we expand its known distribution to North America (New Mexico). The inconspicuous ascomata of Karstenellaconsist of very thin, resupinate apothecia borne on a subiculum. Hypotheses of a close relationship with Pyronema (Pyronemataceae) or other highly reduced apothecial forms are rejected. Combined analyses show that Karstenella constitutes an independent lineage within a highly supported group of the lineages B (Morchellaceae–Discinaceae and Helvellaceae–Tuberaceae) and C (Ascodesmidaceae, Pyronemataceae, Sarcoscyphaceae and Sarcosomataceae), Caloscyphaceae and Rhizinaceae. This corroborates recognition of a monotypic genus and family of Karstenella. A possible sister group relationship with Caloscyphaceae and/or Helvellaceae–Tuberaceaeis suggested. The ascospores of Karstenella are shown to be bi- to multinucleate using DAPI staining. Excipulum structure and/or spore cytology support a shared origin with Caloscyphaceae and/or the Helvellaceae–Tuberaceae sublineage.Karstenella possesses the most reduced form of ascomata found so far outside lineages A (e.g. Ascobolaceae) and C (e.g. Ascodesmidaceae and Pyronemataceae).
