Growing on old wood, leaves, grass, etc. Sporangium .4-.7 mm. in height by .3-.4 mm. in diameter, the stipe often reduced to a mere point or cushion on the hypothallus, and varying thence to nearly the length of the sporangium. The sporangium is narrower than in the preceding species, and the brown wall is usually without granules of lime. It is Didymium curtisii, Berk. Rostafinski and Massee both preserve it distinct from S. rubiginosum. See Plate XV. Fig. 73.
