The thallus varies greatly, and may be very luxuriant in somewhat 
damp localities (f. pendulina) or short and stunted when opposite 
conditions prevail (f. phalerata). The strengthening hyphex occur in 
strands within the cortex, which is formed of shortly branching thick- 
walled hyphe ; the alge lie in groups.
