The characterization these entries are based on is rather incomplete, insofar important features have not been observed or their lack has not been mentioned. This ectomycorrhiza is included in DEEMY as a specific, new name has been applied. Due to the limited character information it will be difficult to differentiate this ectomycorrhiza from many other species included in DEEMY, and therefore, identification on a general scale will be hardly possible. Dryas-based attempts, however, may result in success. |
