ASTRODOCHIUM E. & E., nov. gen. 
Sporodochia innate-superficial, formed by the transformation of 
brown, appressed, branched, radiating fibers. Conidia oblong, contin- 
uous, hyaline, borne singly and terminal on simple basidia. 
ASTRODOCHIUM COLORADENSE E. & E. On fallen leaves of Quercus 
undulata, Morrison, Colo., December, 1896 (E. Bethel, No. 170). 
Epiphyllous, forming round brown spots 3-1 cm. across and having 
the general aspect of Asteroma. The adnate fibers abundantly and sub- 
oppositely branched towards their extremities are soon transformed into 
round or elliptical, subdiscoid, light amber-colored sporodochia }—3 mm. 
diam. consisting of closely packed obclavate, 12 x 24, hyaline basidia 
bearing at their tips the oblong hyaline, 4-6 x 11—-13y, conidia. 
Belongs in Fam. Tubercularieae, Mucedineae. 
SEPEDONIUM TUBERCULIFERUM E. & E. Parasitic on Peziza hemis- 
pherica Wigg. and P. fusicarpa Ger., Nuttallburg, W. Va., July, 1896; 
alt. 1800 ft. (L. W. Nuttall, No. 883). 
Hyphae effused, forming a thin, white layer on the surface of the 
hymenium, becoming pulverulent and yellowish at maturity ; fertile 
hyphae with the ultimate divisions di-trichotomously or verticillately 
branched, the branches lanceolate, 20-30 x 2-23, bearing at their ex- 
tremities the globose conidia 15-18» diam., bearing at symmetrical 
distances on their periphery 8-10 depressed globose, hyaline smooth 
tubercles 6-7» diam. and sometimes separable from the central spore. 
ToruLA ERUMPENS E. & E. On decorticated, weather-beaten wood 
(poplar)? Morrison, Colo., December, 1896 (E. Bethel, No. 166). 
Erumpent in flat, discoid, orbicular or elliptical tufts 3-? mm. diam. 
Conidia cylindrical, 2-5 septate, concatenate, 10-20 x 34-4», dark 
brown, nearly opaque. 
Macrosporium ricr Ell. & Kelsey. On leaves of Ficus elastica, 
Oberlin, Ohio, September, 1896 (Prof. F. D. Kelsey, No. 1076). 
Hyphae amphigenous, very dark brown, fasciculate, septate and 
more or less constricted at the septa, 70-125 x 4-5» forming olivaceous 
tufts as large as a small pin’s head thickly scattered over the large (1- 
2 cm.), dirty white spots with a dull purplish-red border. Conidia 
club-shaped, 3-7 septate, with a more or less complete longitudinal sep- 
tum, 40-50 x 10-16, with a pedicel 20-30,» long. 
Quite different from M. torulosum Pass. on limbs of Ficus.
