ICOM1 Abstract
Determination of ectomycorrhizae is until now exclusively
based on dichotomous keys with alternatives and ranks
selected by the constructors of the keys. DEEMY provides an
interactive key in a hypertext version with the possibility
to start the determination process with any feature. As an
aid, the system ranks the characteristics regarding their
distinguishing capacity. To date, features useful for
characterization of ectomycorrhizae are discussed and
sometimes depicted in different publications. DEEMY,
however, compiles all useful features in a character-list
with one up to several states, gives explanations, provides
informative illustrations, and therefore helps to prepare
detailed descriptions of ectomycorrhizae. The determination
procedure and the multiple evaluation possibilities are
explained on the poster. DEEMY system is designated for
mycorrhizasts, mycologists, and botanists working in soil
ecology, taxonomy and nature conservation. It supports
current and future floristic, ecological and taxonomic
projects on ectomycorrhizae and fungi. DEEMY will be firstly
issued, presented and demonstrated at ICOM 1. Actually, only
a selected number of ectomycorrhizal species are included,
but each second year an updated version will be available.
