The ability of ectomycorrhizal fungal isolates to utilise organic nitrogen (under spruce)							
remarks:	data from Taylor (2000); method Taylor et al (2000)						
	The ability of ectomycorrhizal fungal isolates to utilise gliadin which is an organic nitrogen source						
	in relation to the substrate from which the isolates originated.						
	Isolates obtained from ectomycorrhizas and fruit bodies from four spruce sites along a North-South European transect.						
Sites:	Åheden - Northern Sweden; Klosterhede - Western Jutland Denmark; Waldstein - Fichtelgebirge Germany; Aubure - Vosges Mountains NE France						
							
Key:	Origin of isolate:						
		M= mycorrhizal isolate					
		F= fruit body  isolate					
	Soil fraction in which the ectomycorrhizal tips were found:						
		Org = Organic					
		Min = Mineral					
		n/a = not applicable					
	Diameter of fungal colony after 1 month on solid agar medium containing the insoluble plant protein gliadin as the sole nitrogen source						
	± glucose as a carbon source.						
		(+) slight growth				
		+ 1-3cm				
		++ 3-6cm				
		+++ > 6cm				
		/- intraspecific differences between isolates of  the same species.
