(第2報) Catenulariaの分布及びその菌学的性質について

抄録

In the previous paper it was shown that Catenularia sp. HFES No. 179 and 136 have the constriction on the conidiophore near the foot cell. The purpose of this paper is to describe that morphologically the constriction of conidiophore and physiologically the osmophilic nature are generally observed on Catenularia in our country. Twenty-two strains of Catenularia from various sources were collected and examined. From the results it is considered that they all belong to the one species of Catenularia fuliginea, so the new morphological and physiological natures shall be supplemented to the description of Catenularia furiginea SAITO.
And it is considered that on yokan or sweet cakes Catenularia grow specially by the osmophilic nature.
Suppteniental Description of Catenularia fuliginea SAITO.
Conidiophores are constricted usually at a point of 3 to 10μ of distance from the foot cell and aboveit cylindric with about 2_??_3μ, in diameter.
At the point of the constriction no septa are observed.
And the high osmotic pressure (about 50 Atm.) on culture media is necessary for normal growth.
