A new method by correlation to forecast the optimal time of sporeprints production and collection on sporocarps of Ganoderma resinaceum Boud. (Basidiomycota) on natural substrate

Abstract

Spores features of most fungal species are of prime importance in the process of their identification. These spores could also be used for numerous other studies including fungal genetics, reproduction and molecular biology. Studies involving single spore cultures are numerous in various domains of mycology and these isolated spores could be obtained at best only from spore-prints. These spore prints are most often produced by sporocarps of most Agaricales on field and also in the laboratory after collection. In contrary, Ganoderma in general including G. resinaceum produce spore-prints only on field and for a limited period of time not covering all their life span. These spore-prints could therefore be collected only on the field during a well defined period. The correlation equation Y = a+bX between size of sporocarps and time of growth now renders possible the forecast of the period of spore-prints production by sporocarps of G. resinaceum on natural substrate, thereby enabling collection of these spores at the best time on field for various mycological investigations.
