Mycocoenological research in the Bois de Lauzelle (Ottignies - Louvain-la-Neuve, Belgium).

The influence of the plant cover type on the mycoflora was studied in three different conifer plantations at the Bois de Lauzelle (Ottignies - Louvain -la-Neuve, Belgium) : Picea abies, Pinus nigra var. calabrica cultivar Koek elaere and Pinus sylvestris. These plantations are situated on a plateau wi th acid sandy soils. In each stand, two permanent 400 m(2) square plots wer e marked out and studied by mycocoenological releves, during 15 months. Correspondence analysis (CA) and unweighted pair group method with arithmet ic mean (UPGMA) showed that the mycoflora of the plots from the same stands were more alike than those situated in different stands. Correspondence an alysis gave a list of characteristic species for each stand. No statistical ly significant correlation was found between air temperature and rainfall a nd fruit body production.
