232 Rhodora [SEPTEMBER 
“ In September, 1870, I found large masses of a Gracilaria, which I 
picked up by the armful at East Marion, Long Island. I think likely 
it was G. confervoides Grev., but have misplaced my specimens." In 
N. E. Marine Algae, p. 164 is a similar note, giving the locality as 
Orient. Other than this, there appears to be no record of anything 
but G. multipartita north of the Carolinas. 
It is by no means easy to tell from a herbarium specimen of 
Gracilaria whether the living plant was flat, compressed or terete ; 
and though the writer had seen several specimens from Buzzard’s 
Bay that in every way resembled the European G. confervoides, he 
did not venture to consider them identical, as he could not be cer- 
tain that the flattening shown in all the specimens in question was 
due to their pressing. On Sept. 14, 1902, however, he found on a 
muddy shore at Mattapoisett, Mass., quantities of Gracilaria, in 
dense rounded tufts, the fronds in every part terete with no trace of 
flattening; the branches long, attenuate, acute. There was no indi- 
cation of the flattening at the axils, or of the palmatifid tips, charac- 
teristic of G. multipartita var. angustissima, and it would appear to 
be safe to add G. confervoides to the list of. New England algae. 
The specimens have been distributed under that name as No. 1041, 
Phycotheca Boreali-Americana. 
ACTINOCOCCUS PELTAEFORMIS Schmitz. This plant was formerly 
considered as the tetrasporic fruit of Gymnogongrus Norvegicus 
(Turn.) J. Ag.’ but is now known to be a parasite on the latter, in 
the same way as A. aggregatus Schmitz is on Gymnogongrus Grif- 
Jithsiae (Turn.) Mart. and A. sudcutaneus (Lyng.) Rosenv. on Phy/lo- 
phora Brodiaei (Turn.) J. Ag. It was found by the writer in July, 
1902, at Cutler and at Baker's Island, near Harpswell, both on the 
Maine coast. It will probably be found wherever the host plant 
grows. 
CopIOLUM PUSILLUM (Lyng.) Foslie. In Ruopora, Vol. III, p. 
280, the writer noted the occurrence of this species at Marblehead, 
Massachusetts, but in a form different from the type, and to which 
Foslie gave the name forma Americanum, distinguished by the clava 
being nearly or quite as long as the stipe. At Cutler, Maine, in July, 
1902, the same species occurred, forming a dense coating on rocks 
near high water mark, and composed of plants showing all stages 
from the typical European form to that of the Marblehead plant.
