130 THE MYCORRRHIZAL STATUS IN MOUNTAINOUS VEGETATION IN THE FAROE ISLANDS lar mycorrhizal plant species and ecto- or ericoid plant species could be due to dual infection, but that can not be concluded from this study. The fact that the type which requires least photosynthetic products from the plant, and is Ieast efficient in degrading or- ganic compunds is the most widespread could indicate that there are other factors than phosphorus and nitrogen which are limiting. These could be, for example, tem- perature and/or light. Acknowledgments We thank Professor A.H. Fitter for his helpful criticism of an earlier draft of the manuscript, and P.H. Enkell for his helpful review of the manuscript. Financial assis- tance from Granskingarráð Føroya, Danish Research Councils and the Faroese Museum of Natural History made this study possible.
