1 Described as curved by Herre: the only fruited California plant examined by me had straight 
spores. Note — A straight spore must have its axis straight. A substraight spore must have 
one side-wall straight, — its axis may be thus a little bent. A curved spore must have both 
walls and its axis distinctly bent.
