Abstract:  The ascomycete flora of some Lycopodium species (L. annotinum, L. clavatum, L. alpinum, L. complanatum s.lat., L. selago) has been investigated, mainly on the basis of Nordic, particularly Swedish, material. These species have proved to harbour a rich mycoflora, largely confined to the club mosses and in many cases even restricted to a certain host species. The lycopods studied differ significantly with regard to their fungi. The origin of this mycoflora is discussed. It is considered to be fairly modern and apparently the lycopods were once colonized by fungi inhabiting other xerophytic plats, like Ericaceae and Juniperus.
Twelve Discomycetes and 13 Pyrenomycetes are dealt with and the following new names are published: Discomycetes: Cryptodiscus anguillosporus L. & K. Holm, n. sp., Dasyscyphus inopinatus (Kirschst.) L. & K. Holm, n. comb., Hyalopeziza pani (Vel.) L. & K. Holm, n. comb., Hyalopeziza rubefaciens L. & K. Holm, n. sp., Micropeziza diphasii L. & K. Holm, n. sp., Pseudopeltis perminuta L. & K. Holm, n. sp. Pyrenomycetes: Gibbera lycopodii L. & K. Holm, n. sp., Massarina chamaecyparissi (Rehm) L. & K. Holm, n. comb., Phaeosphaeria marciensis (Peck) L. & K. Holm, n. comb., Venturia lycopodina L. & K. Holm, n. sp.

Abstract:  The development of the fruit bodies of Gyromitra esculenta (Fr.) Pers. was observed in the field in Central Finland (62° 18′ N, 26° 15′ E). The first fruit bodies become visible when snow and ice are still present in the forest. The initial stages and very small fruit bodies were seen to develop during the previous year. The authors believe that there is a mycochrome in G. esculenta which reacts to the short daylengths in autumn and inhibits the de velopment of the young fruit bodies, but which induces their growth in the spring, as the day is lengthening.

Abstract:  The author reports one collection of Helvella hyperborea Harmaja (sect. Acetabulum Diss.) and five collections of H. pedunculata Harmaja (sect. Leucomelaenae Diss.) from inner Quebec, Canada. The recently described species have been known only from northwestern Europe.

Abstract:  The total polypore flora was studied in four nearby forest areas in southern Central Finland (province Etelä-Häme), including the Edessalo nature reserve, and the Vesijako National Park, which is one of the oldest and densest virgin spruce forests in Finland. The field work was done in the years 1978-1980, when 855 specimens were collected and about 720 sight records were made. In all, 97 species were found.
The ecology of most of the species is discussed, and their abundance and the host tree species are presented. Species reported as new to Finland are Antrodia salicina (Bres.) Niemelä, Onnia triquetra (Lenz) Imaz., Rigidoporus vitreus (Fr.) Donk, Strangulidium rennyi (Berk. & Br.) Pouz., Tyromyces lowei (Pil.) Dom. and T. undosus (Peck) Murr. The total distribution of some rare species in Finland is given, and the concept of the so-called ‘taiga element’ is discussed. Preliminary observations are presented on the existence of some fungal communities e.g., the co-occurrence of Amylocystis lapponica (Rom.) Sing., Fomitopsis rosea (Fr.) Karst., Phellinus ferrugineofuscus (Karst.) Bourd. and Phlebia centrifuga Karst. on fallen trunks of Picea abies (L.) Karsten. The susceptibility of different tree species to wood-rotting polypores is discussed, and problems in the taxonomy of some rare species are briefly reviewed.

Abstract:  The new smooth-spored species Inocybe hygrophana Glowinski & Stangl and I. pseudoreducta Stangl & Glowinski are described from the Feredal Republic of Germany. I. hygrophana: Small. When moist, cap sepia brown with a violet marginal zone, gills distinctly light violet, and stipe light bluish violet and pruinose above when young. When dry, cap ochraceous-ferruginous, gills brownish, and stipe bulbillous and brownish. I. pseudoreducta: Medium-sized, cap deep brown with a reddish tint, gills citrine at an early stage, light brown when mature. Stipe marginate-bulbous, totally pruinose, faintly ochraceous to reddish.

Abstract:  Plant material was collected from three localities in Gambia, West Africa. In moist chambers 22 species of Myxomycetes emerged. Five seem to be new to Africa: Cribraria minutissima Schw., Echinostelium minutum deBary, Macbrideola martinii (Alexop. & Bekene) Alexop., Perichaena minor (G. Lister) Hagelst. and Slemonilopsis hyperopia (Meylan) Nann.-Brem. Both the number and diversity of the Myxomycetes that emerged are higher than in moist chambers prepared with Finnish material.

Abstract: Antrodia onychoides (Egel.) Ryvarden, earlier known from the type only, is reported as new to Finland. Its emended description is given, and its taxonomic position discussed. A. ramentacea (Berk. & Br.) Donk is reported from five localities in southern and south-eastern Finland, growing on corticated Pinus sylvestris. Gloeoporus gelatinosotubulosus (Pil.) Bond. ex Kartavenko has been collected from Finland for the first time, and the find is evidently the first outside the U.S.S.R. The species is brieny described, and its nomenclature is scrutinized. The occurrence of Inonotus dryophilus (Berk.) Murrill in Finland is substantiated, and earlier reports of the collections under the names I. dryadeus (Fr.) Murrill and I. hispidus (Fr.) Karst. are corrected. The species of Inonotus occurring in Finland are listed. Junghuhnia pseudozilingiana (Parm.) Ryv. is reported as new to Finland and Fennoscandia, and its identification and ecology are briefly discussed.

Abstract:  Melanogaster ambiguus (Vitt.) Tul. was found in 1977 in two localities in SW Finland. These are the first records of a Melanogaster species in Finland. The Finnish material is described, and the taxonomy of M. ambiguus and related species discussed. A description is given of the two localities and the total distribution of M. ambiguus is outlined.

Abstract:  The mushroom yield in a coppice in Ilomantsi, eastern Finland, was studied during the first three years following aerial MCPA ester spraying. In all three years the yields obtained from the coppice were greater than the yields from the adjacent mixed coniferous forest. MCPA treatment had no acute poisonous effect on the mycoflora but indirectly it caused pronounced changes in the total mushroom yields.
