A specimen apparently of this species, No. 983 in the Kew 
collection, from Westbrook, Maine, E. L. Bolles, under the name 
‘ feticularia echinospora”’ M. is a pulvinate ethalium, 20 mm. 
broad, 5 mm. thick, with a smooth persistent wall; the mem- 
branous folds of capillitium are equally distributed through the 
wthalium; the spores are identical with those in the English

dicularly, and attached above and below to the sporangium-walls, 
which, when mounted in glycerine, are seen to be studded with the 
broken point n some sporangia there are also a few straight
