Basidiocarps of sulphur fungus Laetiporus sulphureus (Bull.: Fr.) Murrill were produced from May to October in 1-4 waves in three model towns of Nitra, Žilina and Zvolen in Slovakia during 1984-1986 and 1991-1992. Basidiospores were released in two main waves (May-June and August-September). The mean of measured values was 6.5 x 10² basidiospores discharged from 1 mm² of hymenophor in the course of 24 hours.
