Abstract: The majority of the dermatophytes (Moniliales, Deuteromycetes) from clinic patients m northern Finland identified in culture, 90 %, fall into three species, Trichophyton rubrum (Castellam) Sabourad, T. mentagrophytes (Robin) Blanchard and Epidermophyton floccosum (Harz) Langeron & Milochevitch, in order of current prevalence. This species range is identical to that found m the south of Finland. Cases of T. rubrum infection have increased particularly markedly in recent years.
Abstract: Ptychoverpa bohemica (Krombh.) Boud. (Pezizales: Morchellaceae) is recorded as new to Norway from two localities in the north of the country (Nordland and Troms counties). Several additional localities are also reported for Finland. The interpretation of some anatomical details and the ecology of the species are discussed.
Abstract: Distribution maps are presented for all the species of Phellinus occurring in Finland and host plant statistics are given for each species. The ecological characteristics and pathogemcity of the species are discussed, and an evaluation made of their economic Importance as pathogens and wood-rotting fungi on merchantable timber and ornamental trees and shrubs.
At present 18 species of Phellinus are known to occur in Finland, 13 on deciduous and 5 on coniferous trees. The most important hardwood-decaying species is P. igniarius (L.) Quél., followed by P. tremulae (Bond.) Bond. & Borisov, which infects Populus tremula. Of the conifer-decaying species, the most harmful is P. chrysoloma (Fr.) Donk (on Picea abies, especially in northern Finland), followed by a much less important species, P. pini (Brat.) A. Ames on Pinus sylvestris. The generic concept of Phellinus is briefly discussed, and some author citations are altered in the specific names according to the changes in the Code of Nomenclature enacted in 1981.
Abstract: This is an introduction to a series of papers devoted to the mapping of the polypore species occurring in Finland. The survey is based on the Finnish national uniform grid system (Grid 27°E), whose unit is 10 X 10 km. For each distribution map all the material available in public Finnish herbaria has been consulted. It is planned to publish the maps at irregular intervals. The principles of the mapping are presented and the biogeography of Finland briefly discussed. The names are given of the most important indigenous and cultivated tree species infected by polypores in Finland.
Abstract: The first Finnish record is given of the rare species Helvella oblongispora Harmaja (sect. Leucomelaenae Diss.), with a photograph of fresh apothecia in situ.
Abstract: The smut fungus Ustilago vuyckii Oudem. & Beijer. has been found for the first time in the southern hemisphere, on Luzula novae-cambriae Gandoger in Victoria, Australia. The total range of U. vuyckii is mapped.
Abstract: The species of the newly described monotypic polypore genus Piloporia Niemelä resembles those of the genus Datronia Donk in the brown hyphae and the distinctly duplex structure of the fruit body context, but differs in having allantoid sopres and encrusted hyphal tips in the pore mouths. The two last-mentioned characters show affinity to lncrustoporia Domanski, but the brown colouration and duplex context separate Piloporia from that genus.
The only species, P. sajanensis (Parm.) Niemelä n. comb. (Antrodia sajanensis Parmasto), is reported as new to Finland, having been collected on Pinus sylvestris. The macroscopical and microscopical features are described and illustrated, and the taxonomy discussed. The world distribution of the species is surveyed, the present locality being the sixth that is known. All the collections have been made in slightly to distinctly continental parts of the Northern boreal zone in Eurasia.
Abstract: The following new nomenclatural combinations for polyporaceous fungi are proposed: Antrodiella hoehnelii (Bres. ex Hohn.) Niemelä (Polyporus hoehnelii Bres.), A. onychoides (Egeland) Niemelä (Polyporus onychoides Egel.), A. romellii (Donk) Niemelä (Poria romellii Donk), Daedaleopsis septentrionalis (Karst.) Niemelä Lenzites septentrionalis Karst.), Fibuloporia mucida (Pers.: Fr.) Niemelä (Poria mucida Pers. = Fibuloporia donkii Domanski) and Phellinus tuberculosus (Baumg.) Niemelä (Boletus tuberculosus Baumg. = Phellinus pomaceus (Pers.) Maire). The backgrounds of these combinations are briefly discussed.
Abstract: Twenty species of fungi were identified in moist chamber cultures of diseased organs of Helianthus annuus L. Severe infection by Botrytis cinerea Nocca & Balbis and Sclerotinia sclerotiorum (Lib.) de Bary was demonstrated, and these species together with Fusarium avenaceum (Fr.) Sacc., F. equiseti (Corda) Sacc., F. oxysporum Schlecht. and F. sambucinum Fuckel form a disease complex which is very destructive on sunflower stands in Finland. These fungi have not been reported earlier on Helianthus annuus in Finland.
Abstract: A list of 44 ascomycetous fungi, mainly Pezizales and Helotiales is presented from a little known area of Labrador, Canada. Two species are reported as new to North America: Gyromitra cf. gigas (Krombh.) Cooke and Cistella grevillei (Berk.) RaschIe. The occurrence of Hyaloscypha lectissima (Karst.) Raitv. in North America needs further study. The known range of many of the species is extended.
