Records of rare aphyllophoroid fungi on Scots pine in Northern Sweden
- 2010

Ingår i: Karstenia. - 0453-3402. ; 50, s. 45-52

Tidskriftsartikel (refereegranskat)abstract
- Wood-inhabiting fungi on Pinus sylvestris were examined in three old-growth forests in northern Sweden. A total of 16 rare species of aphyllophoroid fungi are reported. Among the species discussed are Antrodiella pallasii and Skeletocutis kuehneri which are successors of Trichaptum species and previously known from only a few localities in Sweden, and Byssoporia terrestris and Hydnellum gracilipes which are mycorrhizal species with specific ecological preferences. Three corticioid species from genera Ceraceomyces and Sistotrema represent possible new taxa.

Hygrophorus betulae, a new species described from subalpine birch forest in Finland
- 2020

Ingår i: Karstenia. - : Finnish Mycological Society. - 0453-3402. ; 58:1, s. 1-9

Tidskriftsartikel (refereegranskat)abstract
- A new species, Hygrophorus betulae, associ- ated with Betula pubescens is described from the subalpine zone of northern Finland. The molecular phylogenetic analysis shows that it is closely related to H. mesotephrus, a species described from England and associated with Fagus. In morphology H. betulae is character- ized by the small glutinous basidiomata and the pale pileus with an olive-grey disc zone. The colour of the disc zone is similar to that of H. olivaceoalbus. The species seems to be rare or may be overlooked because of the small and pale appearance.

Hygrophorus exiguus, a new species in subgenus Colorati section Olivaceoumbrini, subsection Tephroleuci
- 2014
-
Ingår i: Karstenia. - 0453-3402. ; 54:2, s. 41-48

Tidskriftsartikel (refereegranskat)abstract
- In Fennoscandia the new species H. exiguus is associated with rather moist old growth mixed Picea abies forests of the Vaccinium myrtillus type. In Southern Europe it is associated with mixed P. abies and Abies alba forests on higher elevations. It seems to be growing solitarily deep in mosses, often among Tricholoma inamoenum. The species is likely to be rare but has a broad distribution in Europe and is found in Finland, Sweden, Italy and France. It is closely related to H. agathosmus, H. hyacinthinus and H. odoratus, but can be segregated from these by its small fruiting bodies, the pinkish tint in the lamellae, with a cap diameter rarely exceeding 20-25 mm. Like H. agathosmus, it has the odour of marzipan or bitter almonds.

Inocybe leiocephala, a species with an intercontinental distribution range – disentangling the I. leiocephala – subbrunnea – catalaunica morphological species complex
- 2014
-
Ingår i: Karstenia. - 0453-3402. ; 54:1, s. 15-39

Tidskriftsartikel (refereegranskat)abstract
- Sequence data and morphological characteristics of specimens determined as Inocybe leiocephala were compared with six type specimens. We conirm I. leiocephala, I. lindrothii, I. subbrunnea, I. fuscescentipes, I. subpaleacea and I. catalaunica as separate independent species. All species except I. subpaleacea and I. catalaunica were shown to have a broad intercontinental distribution range. Inocybe leiocephala has its main distribution in arctic-alpine and subalpine habitats, and I. lindrothii in hemiboreal – boreal zones. Inocybe subbrunnea is conined to nutrient rich, often more calcareous soils and mixed coniferous forests. Both I. fuscescentipes and I. subpaleacea, described from the alpine zone, also grow in boreal forests. Inocybe catalaunica is a species well separated from I. leiocephala, I. lindrothii and I. subbrunnea in molecular data and it appears to be more related to I. tjallingiorum and I. phaeoleuca despite macro-morphological similarities to the I. leiocephala group. The new species I. ohenojae is described here based on material from the alpine zone in Canada. The new combination Inocybe lindrothii is proposed and an epitype is designated. Inocybe saponacea is regarded as a synonym of I. lindrothii. A key to the species is provided.

Inocybe lemmi, a new species of section Marginatae from the alpine region of Sweden
- 2017
-
Ingår i: Karstenia. - : Finnish Mycological Society. - 0453-3402. ; 57:1-2, s. 1-9
-
Tidskriftsartikel (refereegranskat)abstract
- A new species, Inocybe lemmi, is described from alpine areas of Sweden. It is closely related to I. candidipes, associated with Pinus ponderosa and described from the southwestern United States. Both belong to the I. praetervisa group in section Marginatae, reserved for species characterized by a stipe with abundant caulocystidia in the upper half, which are sparse in lower half of the stipe. Other species in the I. praetervisa group have distinctly nodulose heterodiametric spores, while I. lemmi and I. candidipes have basally nodulose to angular spores with an elongated apex. A single collection from the alpine zone in Colorado was identified as representing a third lineage, closely related to I. lemmi and I. candidipes. The holotype of the recently described species, I. tundrae, was studied and is confirmed to be a later synonym of I. rivularis.
