The Life History of Ascobolus Magnificus

SUMMARY

1.	The ascocarp of Ascobolus magnificus originates from a pair of morphologically distinct primordial—a large ascogonium the end of which functions as a trichogyne, and a club-shaped antheridium.
2.	Papulospora magnifica Hotson is an asexual stage of Ascobolus magnificus Dodge.
3.	The intrahyphal mycelium, found in old cultures is simply a case of “Durchwachsungen,” or “cordon interne.”
4.	The strains here reported, which were obtained from germinated papulospores or ascospores, were self-sterile in the experiments conducted, but always produced papulospores.
5.	Sexual reproduction occurs in cultures containing two strains properly chosen.
