2. F. ochraoea Peck, in Rep. JST. York Mus. Nat. Hist., xxxi., 
Bot., p. 56 (1879). Plasmodium vitelline-yellow (teste Dr. Eex). 
^thalia pulvinate, 2 mm. to 1 cm. broad, formed of very closely 
interwoven sporangia, the cortex delicate and membranous or 
hardly developed, yellowish grey or grey, with scattered deposits 
of yellow lime-granules. Capillitium of numerous fusiform or 
branching yellow lime-knots connected by rather short hyaline 
thi-eads. Spores violet-brown, spinulose, 10 to 11 /^diam. — Mass., 
Mon., p. 342. Licea ochracea Peck, in E.ep. N. York Mus. Nat. 
Hist., xxviii. (1875). 
Plate XXIV., A. — e. capillitium and spores, x 280; /. spore, x 600 
(United States). 
Very closely allied to FuUgo se^jtica, from which it differs in the short 
hyaline threads of the capillitium and the larger rougher spores. 
Hah. On rotten wood. — Pennsylvania (L:B.M.41). 
3. F. ellipsospora Lister. Plasmodium 1 .^thalia pulvinate, 
elongate, 4 to 6 mm. long, or irregular and effused, formed of closely 
interwoven sporangia enclosed in a smooth white cortex densely 
charged with Ume, continuous with the white hypothallus. 
Sporangium-walls within the sethalium more or less perfect, mem- 
branous, with deposits of white lime-granules. Columella none. 
Capillitium of large white lime-knots connected by simple or 
branching hyaline threads. Spores brownish-violet, spinulose, 
ellipsoid, 13 to 17 X 10 to 12 ju,. — Physaruvi ellipsosjjorum Post.,

The type specimen of Badhamia coadnata Rost. from Cuba in the 
Strassburg collection is similar to the American specimens of F. ellip- 
sospora ; the large branching lime-knots are connected by very short 
hyaline threads. The account given by Zopf of JSthalioiJsis stercori- 
formis Zopf (Pilzthiere, p. 150, 1884, syn. Fuligo stercoriformis Mass., 
Mon., p. 342) so well describes F. ellipsospora that they appear to be 
the same species.

SPECIES NOT MET WITH IN THE QUOTED COLLECTIONS. 
4. F. tatrica Racib. in Hedw. 1885, p. 169, on decaying 
trunks in Hungary, is described as differing from F. septica in 
having minutely spinulose spores. This does not constitute a 
specific distinction, as the spores of F. septica vary slightly in 
roughness, and are seldom quite smooth when magnified 1200 
diam.
