Spores of Helicocephalum oligosporum

The spores of Helicophalum are produced by disarticulation of swollen segments of  the  helicoid apex of an erect conidiophore.  Thus, the spores are more convex on one side than the other.   The spores are formed in a chain and maintain protoplasmic continuity as they develop.  This is necessary as the spores mature from the base to the apex (check previous microghraph).  The disarticulation points and the continuity 'pores' at the ends of the spore can be clearly seen on the lower of the two spores.
