Fruetifieation resupinate, effused, 
coriaceous, cottony, pubescent, white

640. to 60u long, which bears spores on its 
upper three cells; spores simple, hyaline, even, curved, 15-20 
X ощ-би. 
Fructifications about 2-4 em. long, 1-114 em. broad, some- 
times arranged more or less interruptedly for up to 25 em. 
along the under side of limbs. 
Associated fairly constantly with scale insects on small 
living branches of Quercus on a residence street, Pasadena, 
California. November to March. 
5. canescens is characterized by its white to whitish color, 
cottony structure, and pubescent surface. Spores were ob- 
served attached to one or more of the upper three cells of 
the spore-bearing organ but with the terminal cell giving the 
most indication of spore production. I am indebted to Prof. 
H. S. Faweett for the collection made in March to show this 
species in best fruiting condition. 
Specimens examined: 
California: Pasadena, H. S. Fawcett, comm. by W. A. 
Setehell (in Mo. Bot. Gard. Herb., 44037); same locality, 
А. G. Smith, comm. by H. S. Fawcett (in Mo. Bot. Gard. 
Herb., 44246).
