Wolf has worked on the life history of the black spot fungus, 
Diplocarpon rosae, and has stated that there are two kinds of 
mycelium. The first kind is more or less superficial, lying just 
beneath the cuticle, and from this mycelium subcuticular 
acervuli develop. The second kind is more deep-seated and lies 
within the mesophyll tissues. Connecting the two sorts are 
hyphal strands which pass down not only between the epider- 
mal cells and between the palisade cells but also directly through 
them, so that we have intracellular as well as intercellular hy- 
h 
long haustoria extending down within the cells.
