The authors studied on the sclerotic cells of
Rhinocladiella pedrosoi in a human skin lesion.
The results obtained were as follows:
1) Sclerotic cells originated from chlamydospores and multiplied by germination but not by fission in the infected tissue.
2) According as sclerotic cells swelled into large forms (ca. 5-13μ in diameter), their cytoplasmic material became concentrated and wrinkle and crevice appeared on the cell wall surface. It is the author's impression that they have often been failed to recognized as sclerotic cells with internal septum.
3) A few cells with internal septum dividing the cell content into two parts were observed but no cell with septum dividing into three or four parts.
