A Unique Mode of Spermatization in Cyclotheca kamatii

抄録

This constitutes a report on the occurrence of spermatization in Cyclotheca kamatii Visw. and Ananth. (Mycrothyriaceae) of a unique type not so far reported in literature except a recent report by Tilak in Phyllachora actinodaphnes. The mechanism involved is distinct from the previously reported phenomenon releasing the spermatia through the adjoining ascocarp initial through a basal canal and bringing about the diploidisation of the ascogonial cells. The entire process is thus brought about within the host unlike the normal process so far reported and compares very well with the one reported by Tilak in Phyllachora actinodaphnes. The type of sexuality may be described as hermaphroditic in view of the occurrence of the two compatible gametangia within the same stroma.
