Massee and Salmon. — Researches on 
Sepedonium niveum, sp. nov. (Fig. 70). 
Caespitulis effusis denique pulverulentis niveis; hyphis intertextis 
hyalinis septatis 5-6 ^ diam. vage furcatis hie inde ramulos fertiles 
breves patulos ferentibus ; conidiis in pedicello subulato 9-10 x 2 fi ad 
ramorum apicem acrogenis, globosis initio laevibus dein papillatis 
hyalinis 18-20 n diam. 
Hab. — In fimo Cervi el ap hi ( Red Deer), Kew, Nov. 1900. 
Forming very delicate effused snow-white patches, which eventually 
become powdery owing to the accumulation of conidia on the surface. 
Apparently most nearly allied to S. sphaerosporum (Berk.), Sacc., a 
Brazilian species occurring on the gills of an agaric. 
Several members of the form-genus Sepedonium are known to be the 
conidial condition of species of the ascigerous genus Hypomyces , Tul. ; 
many others, however, to which must be added the species described 
above, have not as yet been connected with any higher form, and 
must for the present be considered as entities. 
Oedocephalum ochraceum, sp. nov. (Figs. 83-85). 
Effusum, pallide ochraceum ; hyphis sterilibus repentibus ramosis 
hyalinis, fertilibus erectis fasciculatis cylindraceis sparse septatis vel 
aseptatis, circ. 200 x 7-8 /x ochraceis apice in vesiculam globosam 
verruculosam 30 /x diam. desinentibus, conidiis ex verruculis oriundis 
oblongo-ellipsoideis pallide ochraceis 4-5 x 2 [x. 
Hab . — Supra fimum cuniculorum, Kew, Dec. 1900. 
Forming pale ochraceous downy patches on Rabbit-dung. Most 
closely allied to Oe. fimetarium (Riess.), Sacc., which differs in the 
conidiophore being distinctly narrowed upwards, and in the larger 
spores. The last-named species is considered by Brefeld to be the 
conidial condition of Peziza vesiculosa. 
Oe. glomerulosum (Bull.), Sacc. (Fig. 119). 
Haplotrichum glomerulosum (Bull.), Harz. Hyph. 33, T. 1, f. 1. 
Oedocephalum glomerulosum (Bull.), Sacc. Syll. Fung, iv, 47 (1886); 
A. L. Smith in Trans. Brit. Myc. Soc., 1899-1900, p. 151. 
Gregarious, at first pure white, then tinged with rose colour or more 
frequently pale salmon-colour with a tinge of yellow; stem sub- 
cylindrical or slightly attenuated upwards, about 200x10^, transverse 
septa variable in number, sometimes absent, inflated head globose, 
verruculose, 30-40 /x diam., conidia elliptic-oblong, smooth, 22-28 
X 1 3-1 3 /x. 
Hab. — On Horse-dung, Mulgrave Woods, Whitby, Yorkshire, Sept.
