Brief description

Monoecious. Receptacle multicelled, consisting of a series of superposed cells giving rise to lateral perithecia and secondary appendages. The primary appendage continues the main axis of the receptacle and bears simple antheridia. Only cell m is visible amongst the perithecial basal cells ( Fig. 19A, m ) and above cell VI, which is usually subdivided in two cells, the additional one named cell VI′ ( Fig. 19B , *). One of the perithecial wall cells of the third tier (w 3) appears characteristically enlarged ( Fig. 19C, E , arrows).

Remarks

Monotypic. See remarks under A. cholevae .
