See article in Nature (1993 I think) by Stewart Chapin and others on 
arctic plants using organic nitrogen, with no evidence of mycorrhizal 
colonization. (Most plants anyhow readily use free amino acids and 
peptides when supplied).  
Finding mycorrhiza-like fungal colonization in plants is not necessarily 
a good indication of the physiological role for the fungi, though some 
recent papers indicate that Phialophora, Phialocephala etc colonize 
alpine/arctic plants. These fungi exhibit a variety of symbiotic 
relationships with plants, depending on the plant and "environmental" 
conditions.
