Abstract:  Descriptions are given of the new genus Singerocybe Harmaja (Singerella Harmaja 1974, non Singeriella Petrak 1959) and of the type species, S. viscida Harmaja. The type of S. viscida is from Finland. Two new combinations are made: Singerocybe hydrogramma (Bull. & Vent.: Fr.) Harmaja and Singerocybe phaeophthalma (Pers.) Harmaja. Two new Finnish localities of S. hydrogramma are reported, one of them being the most northern known for the species. The new species Squamanita basii Harmaja (type from Switzerland) and S. umbilicata Harmaja (type from Finland) are described. S. basii has been misidentified as the North American S. paradoxa (A. H. Smith & Sing.) Bas in Europe; it is known from 11 localities in Europe.

Abstract:  Seven species of the families Hericiaceae Donk, Auriscalpiaceae Maas Geest. and Climacodontaceae Jülich are briefly described, and their distributions in northwestern Europe (Denmark, Finland, Norway and Sweden) are mapped. Hericium erinaceus (Bull.) Pers. is found only in Denmark and southern Sweden. Hericium coralloides (Scop.: Fr) Pers. is rather uncommon in the four countries, but extends from the Temperate zone to the Northern Boreal coast of North Norway. It seems to be absent from the most humid western areas. Its main hosts are species of Betula (ca. 65%) and Populus (18%), preferably trees growing in virgin forests. Creolophus cirrhatus (Pers.: Fr.) Karst. is common in the Southern Boreal zone and farther south; scattered records exist from the Middle Boreal zone and a few from the Northern Boreal zone. No records were found from the highly oceanic western coast of Norway. By far the commonest host genus of C. cirrhatus is Betula (69.5%), followed by Populus (25%). Dentipellis fragilis (Pers.: Fr.) Donk is a rare, predominantly Temperate to Hemiboreal species, favouring Fagus sylvatica (50%) as its host. In Finland D. fragilis was found on Acer tataricum, Alnus sp., Prunus padus and Sorbus aucuparia; a new find is reported from the central part of the Middle Boreal zone, from Acer platanoides. Auriscalpium vulgare S.F. Gray has a relatively even distribution over the Temperate to Middle Boreal zones; only isolated records exist from the Northern Boreal zone. It is found equally frequently in the oceanic and continental parts of the area, growing on the cones of Pinus sylvestris (ca. 90%) and Picea abies (10%). Gloiodon strigosus (Swartz: Fr.) Karst. occurs sparsely throughout the Boreal zone, but is absent from the Temperate zone. It, too, is indifferent to the climatic oceanity, and it grows mainly on Populus tremula (ca. 46%) and Alnus (23%). Climacodon septentrionalis (Fr.) Karst. is a hemerophilous species, restricted to the Temperate and Southern Boreal zones. It is absent from oceanic western Norway and Denmark. Almost 20 hosts are listed, the commonest being Acer platanoides (ca. 49%). The vegetational zones in northwestern Europe are presented in a map which has been revised according to the most recent information, particularly as regards the Nerwegian coast.

Abstract:  Studies on the occurrence of pathogenic root-infecting fungi in different crop sequences in South Finland revealed Microdochium bolleyi (Sprague) de Hoog & Hermanides Nijhof on roots and stem bases of barley and wheat. The fungus was usually isolated together with the major pathogens Gaeumannomyces graminis (Sacc.) v. Arx. & Oliver, Bipolaris sorokiniana (Sacc.) Shoem. and Fusarium species. The cultural and morphological characteristics of the isolates examined agreed well with the original description of M. bolleyi. The fungus was most prevalent on mature cereal roots. Roots of barley and wheat were more often inhabited by M. bolleyi than those of oats or non-graminaceous plants. In crop sequences barley increased, but oats decreased the number of roots invaded by M. bolleyi.

Abstract:  The mating system of Phlebiopsis gigantea (Fr.) Jülich, a common decay fungus of coniferous wood and a biological control agent used against Heterobasidion annosum (Fr.) Bref., is shown to be bipolar. Clamp connections can be found in both hetero- and homokaryotic mycelia. Homokaryotic fruiting occurs fairly frequently in pure cultures. Collections from Finland, Poland and France proved to be interfertile.

Abstract:  Two new species, Inocybe mytiliodora Stangl & Vauras and Inocybe urceolicystis Stangl & Vauras, are described from Finland. Both are smooth-spored and have metuloid cystidia. I. mytiliodora is characterized by a smell reminiscent that of Mytilus, and short, broad and thin-walled hymenium cystidia. The stipe of this species is not pruinose. The best differentiating character of I. urceolicystis is found in the microscopy: the cystidia are nearly unique to the smooth-spored species in the genus in being rounded basally. That species has pruinose stipe apex and spermatic smell.
Both rare species are described and discussed, and the descriptions are completed with photographs, and habitus and microscopical drawings. Inocybe appendiculata Kühner and I. nematoloma Joss. are reported as new to Finland.

Abstract:  Five rare species of glassy-haired Hyaloscyphaceae are treated and illustrated, three of them from their type specimens. Unguiculella xylemicola Bøhler is shown to be a synonym of Hyalopeziza pani (Vel.) L. Holm & K. Holm and this species is transferred to the genus Urceolella Boud. on the basis of the chemical characters of the hairs. The type of Urceolella curvipila (Karst.) Raschle is shown to have multiseptate hairs. This feature is coupled with KOH-instability of the solidifying substance. A parallel case is seen in the type of U. appressipila Graddon and it is suggested that hair septation should be accepted in Urceolella. A recent collection of Unguicularia raripila Höhnel, which was formerly known only from the type collection, is treated and a new combination is proposed, Hyalopeziza raripila (Höhnel) Huhtinen, n. comb. The material studied offers further proof that solid vs. luminal hairs is not a valid generic character in the glassy-haired Hyaloscyphaceae.
