They serve in addition, as Pyronema, for the nourishment of the growing asci as the reserve materials in their end branches (the paraphyses) disappear at the maturity of the asci. As in Pyronema confluens, so also in Ascodesmis nigricans, the male nuclei may degenerate prematurely in the antheridium. In this case amphimixis is absent and the female nuclei pair autogamously in the.
