Stigmina Saccardo (p. 608) Hyphae epiphyllous; conidiophores very short or obsolete; coni- dia ovate or elongate, 3 or more-celled, aggregated. S. briosiana Far. causes disease of apricots in Europe. Ceratophorum Saccardo (p. 608) Hyphae creeping, scant; conidiophores short, erect; conidia fusoid or cylmdric, 2 to many-septate, dark or reddish-brown. A small genus.
