Abstract:  A new species belonging to the family Boletaceae Chev. (Agaricales) is described: Suillus lapponicus Harmaja. It is fairly closely related to S. variegatus (Fr.) Kuntze, from which it differs mainly in the decurrent hymenophore, slightly wider pores, somewhat darker KOH reaction of the pileus surface and context, larger spores, slightly darker spore wall which becomes red-brown in KOH, and the presence of two kinds of pleurocystidia, both differing from those of S. variegatus. S. lapponicus is known from one locality in Finnish Lapland, from dry heath forest, apparently forming an ectotrophic mycorrhiza with Pinus sylvestris L. Carminophilic basidial granules and spore wall are reported in S. lapponicus.

Abstract:  A new species of Myxomycetes, Physarum apiculosporum Härkönen, is described from Finland. It was first obtained on Hordeum seeds in moist chamber culture. It resembles Physarum ovisporum G. Lister in being grey, sessile, sporangiate or plasmodiocarpous and having oval spores. The spores differ from those of P. ovisporum in being more oval, bigger, darker, smooth and apiculate. It was possible to cultivate the species from spore to spore in a simple medium of boiled A vena seeds on filter paper in a Petri dish.

Abstract:  A new species of Myxomycetes, Lamproderma puncticulatum Härkönen, is described from Finland. It has dark brown spots on the peridium and the capillitium is light brown throughout. It was growing on living sporophores of Cantharellus tubaeformis Fr.

Abstract:  The Finnish taxa of the genus Boletus are presented. Boletus impolitus Fr. is recorded for the first time from Finland as are also B. edulis Bull. ex Fr. ssp. edulis f. arcticus Vassilk., f. aurantioruber (Dick & Snell) Vassilk. and f. citrinus (Pelt.) Vassilk. The problem of the delimitation of B. spadiceus (Fr.) Quél. and B. lanatus Rostk. is discussed.
The Finnish distributions are given for all the taxa, mostly on the basis of herbarium material. The only species found throughout the country are B. edulis, B. piperatus and B. subtomentosus; most of them are quite southern in their distribution, many occurring only in the oak zone. Their ecology is discussed.

Abstract:  A new species of Myxomycetes, Comatricha nannengae Härkönen, is described from N Norway and S Finland. It most closely resembles C. nigra (Pers.) Schroet., but differs from it in being smaller and having a complete surface net.

Abstract:  The anatomy, distribution, pathology and cultural characters of Phellinus pomaceus (Pers. ex S. F. Gray) Maire are described on the basis of ca. 470 North European specimens. The main anatomical features separating the species from the P. igniarius complex are the subparallel dissepimental hyphae and thin-walled skeletals in the context. P. pomaceus is fairly common in hemiboreal and temperate southern Fennoscandia, but does not extend farther north. In this region, it occurs almost exclusively on Prunus species, mainly P. domestica L., P. cerasus L. and P. spinosa L., but it has been reported only twice from P. padus L., the commonest Prunus species in Fennoscandia. The cultural characters and anatomy show that P. pomaceus is taxonomically homogeneous in N Europe, except perhaps for a form growing on Crataegus.
A lectotype is selected for P. pomaceus, and the taxonomic position of some closely related taxa (Polyporus corni Velen., Fomes pomaceus f. crataegi Baxter, Fomitiporia prunicola Murr.) is shortly discussed.

Abstract:  The author has found Peziza ovilla Peck (Pezizales), a species described from North America, in Kuusamo, northern Finland. This find is the first reported from Europe. The species is considered to belong to the genus Leucoscypha Boud. in its recently amended delimitation, and the following new combination is made: Leucoscypha ovilla (Peck) Harmaja. A description of L. ovilla is given, and the species is compared with the closely related L. rhodoleuca (Bres.) Svrček, type material of which has been examined. Both species possess exceptionally thick-walled excipular hairs, and their paraphysis cells contain four or two nuclei.
The nuclei of the cells of the apothecium of various species of Leucoscypha sensu lato, including the type species of the genus, are carminophilic. This feature, also observed previously in the genus, appears truly diagnostic of Leucoscypha and also supports the recently broadened delimitation of the genus.

Abstract:  Species of Agaricales, consisting of all the major families are reported from Turkey and Iran; a few records are from Afghanistan. Collections of Conocybe pubescens (Gill.) Kuhn., Nolanea sericea (Merat ex Fr.) P.D. Orton, Panaeolus teutonicus Bride & Metrod and Podaxis pistillaris (L. ex Pers.) Morse from Kuwait, and Lentinus lepideus (Fr. ex Fr.) Fr. from Pakistan are noted in passing. Pleurotus eryngii Fr. ex DC. was recorded in donkey food from Afghanistan. Eighty five agarics, four boletes (one not identified to species) and twelve Gasteromycetes are listed along with seven records from other families (Auriscalpiaceae I, Bankeraceae I, Cantharellaceae 2, Clavariaceae I, Hydnaceae & Gomphaceae 3). Two Ascomycetes, Morchella esculenta Pers. ex St. Amans and Hypoxylon sassafras (Schw. ex Fr.) Curt. are recorded in an appendix. The most notable finds are Amanita valens Bull. ex Fr., Collybia fuscopurpurea (Pers. ex Fr.) Kumm. agg., Conocybe coprophila (Kuhn.) Kuhn., Cortinarius olivaceo-fuscus Kuhn., Inocybe gymnocarpa Kuhn., Lactarius acris (Bolt. ex Fr.) S.F. Gray, L. ruginosus Romagn., Leccinum quercinum (Pil.) Green & Watling, Lentinellus tridentinus (Sacc. & Syd.) Sing., Lentinus degener Kalchbr., Lepiota cygnea Lange, L. jubilaei Joss., Micromphale brassiocolens (Romagn.) P. D. Orton, Psathyrella agaves R. Mre., Rhodocybe mundula (Lasch) Sing., R. truncata (Schaeff. ex Fr.) Sing., Rhodophyllus (Eccilia) fanicus Romagn., Russula adulterina Fr. s. Melz. & Zvara, R. maculata Quél. and R. subfoetens Smith. Of particular note is the list of members of the Secotiaceae and Tulostomataceae which characterise arid areas; Schizostoma is apparently a new record from Iran. The list contains several other species evidently unrecorded for the countries documented, but caution must be exercised as our knowledge of the fungus floras of these regions is very poor. As much of the material lacked field data or was immature or both, some determinations are necessarily tentative. The fungal sociology of the areas however is indicated, as is the great potential of the mixed frondose/conifer woodland of Northern Turkey.

Abstract:  What has been regarded as Helvella acetabulum (St-Am.) Quél. in Fennoscandia is shown to be a diverse assemblage of species. This is due partly to a collective species concept, partly to true misidentifications. Two new species are described: Helvella arctoalpina Harmaja and H. dryadophila Harmaja. The diagnostic characters, phenology and distribution of H. acetabulum s.str. and the two new species are presented; the concept of the first taxon is restricted to a large, rather pale, early southern species, while the other two are small, dark, late arctic-alpine species. Differences in anatomy, including some ‘new’ features, were observed between the species, and the usefulness of such characters at specific level in the genus Helvella St-Am. is emphasized.
Four quantitative cllaracters of H. acetabulum, H. arctoalpina and H. dryadophila were analysed statistically. The material for H. dryadophila was insufficient for comparison, but highly to fairly significant differences could be shown between the two other species.
H. pocillum Harmaja, described earlier, is reported as new to Norway, this being the second known collection of the species. H. palustris Peck, which does not belong to the acetabulum group, is a valid species occurring in northern Finland and new to this country.
