These specimens differ from C. ilicina Sace. Wil. ‘p. 274), the 
spermogone of Valsa Aquifolii Nits., in the total absence of a 
conceptacle (cf. Nitschke, Pyr. Germ., p. 231), as well as in the 
smaller spores. The bases of the pycnidia are simply embedded 
in the cortex. The centre of the pustule, before it bursts, is 
marked with a whitish dot (from the loosened epidermis) and 
afterwards the disc is surrounded by the pale upturned edge and 
the black zone, so that it often presents a distinctly annulated 
appearance that reminds one of C. annulata.
