This is probably for the purpose of obtain- ing a greater amount of nutriment for the development of the fruit spores, which are formed oy the growth and branching of this neighboring (auxiliary) cell. 390. Uses of the red algae.— Many of the red algae develop quantities of a gelatinous sub- stance in their tissues. Several of these are used for the manufac- ture of gelatines and agar-agar. Gracillaria lichenoides and wrightii are used for this purpose, the former
