Species included
THE LICHENS OF BELGIUM AND LUXEMBOURG. AN ANNOTATED CHECKLIST 41
Organisation of the checklist
The present checklist includes all taxa of lichenized and lichenicolous fungi which have
been recorded in the study area. Non-lichenized and non-lichenicolous fungi are only
included if
• they are loosely or doubtfully associated with algae or cyanobacteria (e. g. Naetrocymbe
fraxini);
• they have often been considered as lichens in the past (e. g. Naetrocymbe saxicola);
• they have traditionally been studied by lichenologists (e. g. some species of Caliciales);
• they are fungicolous on species occasionally considered as lichens (e. g. Nectriopsis
indigens on Naetrocymbe saxicola);
• they are genuinely non-lichenized fungi that look like lichens and have never been
collected and studied by other mycologists (e. g. species of Lichenothelia and Peridiothelia).
We also include some lichenicolous species which are likely to be just saprotrophic and
not truly (i. e. obligatory) lichenicolous. The non-lichenized genera Mniacea Boud. and
Sarea Fr. have not been included.
As a rule, we only accept taxa (written in boldface) for which we have studied the
corresponding specimens, and published relevant data in one of our recent papers. Thus,
species which have never been published from the study area are never included: there is
thus no new report of the occurrence of any species in the study area. For some poorly
known genera, like Verrucaria, we also accept a limited number of species which have
been published rather recently by other lichenologists, but for which we have not examined
any material. Older published records for which we were unable to examine any
corresponding specimens have not been accepted, unless otherwise stated; such species
which are doubtfully present in the study area are listed after the accepted taxa, and are
printed in italics.
Data provided for each species
For each accepted taxon, listed in alphabetic order, the following data are provided (some
being optional):
• the name, possibly preceded by the symbol (*) if it is a lichenicolous lichen, * if it is a
lichenicolous fungus, (+) if it is a doubtfully lichenized fungus, and + if it is a nonlichenized
fungus;
• common synonyms, and synonyms found in the literature of the study area [for Belgium,
the literature published after Duvigneaud & Giltay (1938), and for Luxembourg,
that published after Koltz (1897) has been screened for synonyms];
• known or presumed teleomorph or anamorph connections;
