A considerable amount of data has been published on morphological and
anatomical characteristics of ectomycorrhizae but these are dispersed
in several, sometimes not easily available, journals. The few keys tha
t exist are mostly based upon host tree genera. No comprehensive deter
mination tools for non-experts are available. An information system fo
r specific characters of ectomycorrhizae and an interactive key are no
w provided by DEEMY on CD-ROM.
