Obviously, maintenance of an energy supply to sustain
growth of sporophores requires release of compost compounds
by the action of cellulase and other hydrolytic enzymes.
Endocellulase activity fluctuates in parallel with the flushing
cycles and is directly correlated with crop yield (Claydon,
Allan & Wood, 1988 ; Smith et al., 1989). It therefore seems
that the rapid increase in biomass during fruit body
enlargement will act as a (carbon) sink and will drive
mechanisms that temporarily increase the carbohydrate uptake
by the mycelium.
