and stained with aniline safranin and light green. The safranin had collected 
in the corners of these cells, a fact which helped to distinguish them from those of the 
surrounding tissue. Though nothing can be definitely stated, it is possible that they 
were the cells of an immature antheridium. 
Fig. B. Transverse section through the sporeling and part of the prothallus, drawn from two 
consecutive sections at the level marked x x in diagram A. x 53. 
L = leaf; R — root; T = storage tuber; b — bud ; E.S = embryonic swelling; P = prothallus ; 
C = crown of prothallus; F = fungal hyphae ; A = antheridium ; rh = rhizoids ; D = debris. The 
sections which were lost occurred just above the level marked x x . 
Besides the leaf, root, and storage tuber already referred to, the sporeling 
possessed a tuberous mass of tissue, which was partly immersed in the prothallus and 
partly free. This body consisted of parenchymatous cells, which differed from those 
of the gametophyte in that they contained no fungal hyphae, and were in a better state
