Abstract
Mycelium of Haplosporangium parvum was treated as described by Scholl. A Debye-Scherrer diagram of the extracted and oxidized mycelium showed, besides minute amounts of corundum, the typical sequence of lines for chitin. There were no lines for cellulose in this diagram. Nitrogen determinations of the extracted and oxidized mycelium (N = 5.77, 5.91%) confirmed these findings which are in disagreement with the histo-chemical investigations of Breslau (J. Histochem. Cytochem. 3:141. 1955.).
