    On the subdivision of the genus Ceratocystis
    (1975) Weijman, A.C.M.; De Hoog, G.S.
    The desirability is discussed of a subdivision of the genus Ceratocystis into a group characterized by the presence of a phialidic conidial state, and a group in which the conidia are usually produced exogenously. Corroborative evidence for this arrangement is found in the carbohydrate constitution of the cells: in all examined species of the former group (Ceratocystis s.str.) rhamnose and cel-lu' :se are absent, whereas in the latter both components are present (Ophiosto-ir. H. et P. Sydow).
