Interpretation of Microclimate Data in Relation to Basidiospore Release by Fomes annosus. Robert A.

Atmospheric moisture and wind velocity measured 2 ft above sporophores of Fomes annosus were significantly correlated with numbers of basidiospores trapped immediately beneath the sporophore. However, similar climatic data taken at the level of the sporophore, i.e., much nearer to the site of interaction, showed no such relationship with the number of spores trapped.
