G. Farlow that I have had the privilege of examining it and of 
reporting the results. It will be noted that, although the list in- 
cludes several interesting species, it has happily been unnecessary 
to record any new species. 
Ceratiomyxa fruticulosa (Muell.) Macbr. Punta Arenas, 
Chile, March, 1906. 
Ceratiomyxa fruticulosa (var. flexuosa List.). Corral, 
Chile, December, 1905. This extremely delicate form is inter- 
esting, but seems hardly worthy of even the varietal rank given 
it in the Lister Monograph. 
Badhamia panicea (Fr.) Rost. Buenos Aires, Argentina, 
December, 1905. A somewhat scanty specimen, but fairly char- 
acteristic. 
Physarum globuliferum (Bull.) Pers. Corral, Chile, De- 
cember, 1905. 
Physarum dictyospermum List. Punta Arenas, Chile, Feb- 
ruary, 1906. It is interesting to find this apparently very rare 
species in Chile. The only other recorded gatherings are from 
New Zealand, Switzerland and Australia. The specimen from 
Punta Arenas agrees in every particular with the description and 
figures furnished by Miss Lister, except that the slender, black 
stalks are somewhat longer (0.7 mm.) and the black columella is 
clavate and attains a height of one-half to two-thirds that of the 
sporangium. The specimen consists of about twenty sporangia 
growing on a mass of decayed vegetable matter. 
Physarum viride (Bull.) Pers. Concepcion, Chile, Novem- 
ber, 1905 ; Corral, Chile, December, 1905. 
Physarum polycephalum Schw. Temperley, Argentina, April, 
1906. This is the typical form, with undulate, yellow sporangia, 
borne in clusters on fasciculate stalks. 
Physarum penetrale Rex. Corral, Chile, December, 1905. 
A fine gathering, which extends considerably the known range of 
this species in the southern hemisphere. 
Physarum brunneolum (Phill.) Mass. Punta Arenas, Chile, 
March, 1906. An extraordinarily robust form of this species, 
occurring in fair abundance on decayed wood. The dirty-white 
or pale-tawny sporangia are borne on stout or slender reddish-
