Sydowia polyspora was found to be seed borne on true fir (Abies spp.) where it is associated with two serious diseases; current season needle necrosis (CSNN) and Sclerophoma shoot dieback [1]. To our knowledge, S. polyspora was previously only reported to be seed borne on Scots pine (Pinus sylvestris) [3]. In 2009, we discovered S. polyspora on Norway spruce (Picea abies) seedlings from germination tests at the Norwegian Forest Seed Center. This indicated that S. polyspora also was seed borne on spruce. Based on this, we wanted to investigate how widespread S. polyspora was on conifer seeds. In 2010, we tested 44 seed lots from 8 genera. S. polyspora was isolates from seeds from the following genera; Abies, Larix, Picea, Pinus, Pseudotsuga, Thuja, and Tsuga. Interestingly, they are the exact same genera that Funk [2] reported S. polyspora from on diseased foliage and shoots. We found S. polyspora on Norway spruce harvested in 1970, thus, the fungus may survive for decades in seed lots. In Norway, Sclerophoma shoot dieback has been found on Norway spruce in Christmas tree fields. Fungal species from a number of other genera were also detected in the seed test, but here we only report S. polyspora.

Abstract
Norwegian goat milk production is based on summer grazing on diverse forest or alpine rangeland, and the quality of these pastures is important for milk quantity and quality. We used n-alkanes and long chained alcohols found in plant wax as markers to estimate diet composition in goats grazing on a heterogeneous rangeland during two periods in summer; early (beginning of July) and late (end of August). The goats were fitted with GPS collars that recorded their position. Preliminary results show a diverse diet, where ferns, sedges, blueberry (Vaccinium myrtillis) and birch were preferred in early summer. In late summer the diet was particularly diverse, coinciding with a general decline in plant quality.
