Abstract:  The following new species are described (all the types are from Finland): Cystoderma saarenoksae Harmaja, Cystoderma niveum Harmaja, Hygrophorus korhonenii Harmaja, Mycena lammiensis Harmaja, and Mycena occulta Harmaja. Melanoleuca brachyspora Harmaja (nomen novum) must replace M. brevispora Harmaja (non Singer). The following new combination is made: Hygrophorus subviscifer (Karst.) Harmaja. Hygrophorus albidus Karst. (lectotype selected here) and H. spodoleucus Moser are reduced to synonymy with H. subviscifer. Mycena pelianthina (Fr.) Quél. is reported as new to Finland.

Abstract:  A new genus, Gelatoporia Niemelä, is described, to embrace resupinate polypores with a monomitic structure, clamped hyphae and white-rot. G. pannocincta (Rom.) Niemelä, n. comb., is redescribed. G. subvermispora (Pilát) Niemelä, n. comb. (type of the genus), is reported as new to Fennoscandia. Tyromyces canadensis Overh. ex Lowe (Antrodiella overholtsii Ryv. & Gilb.) is reported for the first time outside North America; its characteristics, taxonomy and nomenclature are discussed. Skeletocutis carneogrisea David is reported as new to Finland and provided with some ecological notes. Skeletocutis odora (Sacc.) Ginns is shown to be an older name for S. tschulymica (Pilát) Keller, Antrodia pulvinasccns (Pilát) Niemelä, n. comb., for A. plicata Niemelä, and A. macra (Sommerf.) Niemelä, n. comb., for Trametes salicina Bres. (Antrodia salicina). Most species are illustrated by photographs and microscopic drawings. A new method of mdicating microchemica reactions is proposed and the reliability of Cresyl Blue in the polypore taxonomy is reviewed.

Abstract:  A new species, Unguicularia equiseti Huhtinen, characterized by its branched hairs, is described from SW Finland. T he species grov.s on blackened stems of Equisetum sylvaticum L. A new collection of a rare discomycete, Albotricha laetior (Karst.) Raitv., is described and discussed, and the species is considered lignicolous. A warning is given that certain mountants currently in common use frequently have a shrinkmg effect. In many cases sections revived in these mountants fall to regain their natural dimensions. The taxonomic importance of this phenomenon is briefly discussed.

Abstract:  Floristic notes are presented on 53 taxa of Laboulbeniales from various parts of the Palaearctic Region and one taxon from Taiwan. New species records are given for 33 countries or islands. Special attention is paid to the U.S.S.R., for which there are only scattered records in the litterature. The northernmost records of Laboulbeniales are reported from Tit-Ary (Rickia hyperborea Balazuc) and Bulun (Laboulbenia vulgaris Peyritsch), by the Lena River, north of 70°N in Yakutia.
Laboulbenia egens Spegazzini, occurring on the carabidicolous genus Tachys (s.Iat.), is recognized as a species separate from L. pedicellala Thaxter, occurring on the genera Bembidion (s.lat.) and Dyschirius. The variability of L. pedicellata is discussed. Five new taxa are described: Laboulbenia broscosomae n.sp. on Broscosoma baldense Rosenh. from Italy, L. eubradycelli n.sp. on Bradycellus spp. from many European countnes, L. kobilae n.sp. on Neotrechus sururalis ssp. suturalis Schr. from Yugoslavia, L. marvinii n.sp. on Bembidion dentellum (Thunb.) and B. starki Schaum from Austria, the Federal Republic of Germany and France, and L. luxurians subsp. immaculata n.subsp. on Bembidion semipunctatum (Donovan) from Austria and the Leningrad Region in the U.S.S.R.

Abstract:  Boletus gabretae Pit. was described by Pilát in 1968 from Czechoslovakia. It is close to B. junquilleus (Quél.) Boudier, but differs in the reticulated upper part of the stipe. Their affinities with other boletes are discussed. The Finnish locality at Åvensor, Korppoo, is near a limestone quarry.

Abstract:  A polypore species, Skeletocutis jelicii Tortić & David, hitherto known only from Yugoslavia, is reported from Finland. It differs from all the other species of Skeletocutis Kotl. & Pouz. found in Finland by its monomitic hyphal system and small subglobose spores. The three collections were made from very decayed coniferous wood in protected areas.
S. jelicii is thoroughly redescribed and illustrated. Its distribution and ecology, and also the concept of the genus Skeletocutis are briefly discussed.

Abstract:  Eight species are recognized in the subsection Scrobiculati in NW Europe: Lactarius scrobiculatus (Scop.: Fr.) Fr. , L. leonis Kytöv ., L. olivinus Kytöv., L. tuomikoskii Kytöv., L. auriolla Kytöv., L. resimus (Fr.) Fr., L. aquizonatus Kytöv. and L. citriolens Pouzar. Five of them are new and are described here. The distribution of each species in NW Europe is mapped, and their ecology and relationships are discussed.

Abstract:  The maturation of the perithecia of the pathogenic pyrenomycete Linospora ceuthocarpa (Fr.) Lind, its spore liberation, mode of infection, and the development of symptoms on aspen leaves were investigated. The study also included the histological examination of mfected leaves and a description of the cultural characteristics of the fungus. Perithecia matured in the spring, spore liberation began in the third week of June, followed by dispersal and infection. Lesions appeared on aspen leaves by the third to fourth week of July. Fast growing semimature leaves were most susceptible.

Abstract:  Cystoderma adnatifolium (Peck) Harmaja (Agaricales: Tricholomataceae) is reported from Spitzbergen (Svalbard) for the first time. A new species, Cystoderma arcticum Harmaja, is described from Spitzbergen. It belongs to the group of C. fallax Smith & Sing., but has larger spores than the other species of the group.

Abstract:  The author describes the new species Sowerbyella brevispora Harmaja (Pezizales) from South Finland. It differs from the other species of the genus in the fulvous apothecia, smaller spores and thicker walls of the excipular hairs. S. brevispora was found among needles of Picea abies on non-calcareous soil. The new combination Sowerbyella bauerana (Cooke) Harmaja is also made.
