Parts of thallus with plurilocular sporangia. (a, b, about 200 : 1; c, 150 : 1). The only differences I have found were that the length of cells in the upper part of the assimilating filaments attain a greater length than in my plant (more than double), and that "le sommet de ces derniers [filaments longs] se transforme en longues cellules hyalines: le pseudo poil", while those in my plant all contain chromatophores. The shape of the chromatophore is not mentioned by Mmc Weber. Judging from the description and figure of Heydrich his plant shows the following differences. 2*.
