The ascomycete Hypoxylon macrosporum (Xylariaceae, Sordario-mycetes) is recorded for the first time from Iceland. It was found on a dead twig of Salix phylicifolia in Skaftafell National Park in 2005. Hypoxylon macro-sporum has a quite extensive distribution, but is infrequent outside Scan-dinavia.

In August 2008 eighteen specimens of at least ten species of agarics (mushrooms) were collected on Surtsey. Entoloma sericeum was well established in grassland in the oldest part of the gull colony and at least seven ectomycorrhizal species, Hebeloma collariatum, H. marginatulum, H. mesophaeum, H. vaccinum var. vaccinum, Inocybe lacera var. lacera,...

Twelve species of cup-fungi in the orders Pezizales and Helotiales are reported for the first time from Iceland and comments are made on eight species previously reported. Distributions and habitats are noted. Newly reported records of species occurrences are as follows: Ascocoryne cylichnium, Gloeotinia granigena, Melastiza flavorubens, Octospora...

A new anamorphic genus, Basidiopycnides, and its type species, Basidiopycnides albertensis, are described. Strains of Basidiopycnides albertensis produce what superficially appeared to be a Graphium-like conidial state with percurrently proliferating annellophores. Detailed morphological and molecular data analysis showed these isolates represent a...

It is foreseen that afforestation will increase in the near future in Iceland. There has been an ongoing debate on what effects afforestation will have on biodiversity and the ecosystem overall. To answer some of the questions that have been raised the ICEWOODS project was started in 2002 to investigate how afforestation would affect biodiversity a...

Endophytic fungi were isolated from surface-sterilized needles of the Siberian larch. Samples were collected from a native growing site of the Siberian larch in north-western Russia and from sites in Russia, Finland and Iceland where the Siberian larch has been introduced. The isolated fungi were classified to operational taxonomic units (OTUs) usi...

Sampling of beetles, beetle galleries, and stained tree tissues by ourselves and others to obtain isolates of ophiostomatoid fungal species yielded three Ceratocystiopsis-like entities. Using partial rDNA sequences, these were previously identified as being different from both each other and all other described species of Ceratocystiopsis and Ophio...

The effect of ectomycorrhizae on damage caused by Otiorhyncus larvae and on plant growth was evaluated in a 3-yr field experiment. Russian larch seedlings, inoculated with ectomycorrhizal fungi, were compared with uninoculated plants. Assessment of larval damage at the end of the first growing season showed a significant effect of treatment on dama...

Two potential wood-staining fungi that superficially resemble species of the genus Ceratocystis s.1. were investigated employing morphological criteria and rDNA analysis. After morphological comparison with Togninia minima (Thl. and C. Thl.) Berl., they are assigned to Togninia as Togninia fraxinopennsylvanica (Hinds) n.comb. and Togninia novae-zea...

Fungi were isolated from soil samples collected at the farm Brydju-holt,in Southern Iceland in the fall of 1981 and 1982, from five adjacent sites, each representing different vegetation. Using soil dilution method the fungi were isolated and grown in pure culture. Only the species which could be identified to a species are reported or 5 zygomycete...
