NOVA SCOTIAN FUNGI—SOMERS. 465 
9. Hydnum, corraloides, Scop, very beautiful; like a small 
cauliflower, with numerous spines on the under surface 
of the divisions of the pileus.* 
10. Ditiola, radicate, Fries, rooting ditriola disk, golden yellow, 
growing on pines leaves, amongst mosses and lichens. 
11. Apyrenium, liguatile, Fries, (wood loving Apyrenium). 
Subglobose, hollow, yellow or reddish; growing on 
decaying wood. 
12. Scorias,f spongiosa, Schwt. “The spongy mass which you say 
grew on alder is the fungus.” It is a curious thing, and I 
wish we could get more definite information about its 
development. I have never collected it myself. It 
generally grows on birch. I would be glad to get very 
young stages of it, yours is an intermediate one. When 
mature it is black like a cinder. Perhaps you will get 
mature specimens later. True enough, later Mr. Gib- 
son collected specimens which presented the character 
indicated by the Prof. In a note received afterwards 
from Prof. Farlow, he informed me that he had collected 
the fungus in New Hampshire growing as in Nova 
Scotia, on the alder. 
13. Rostella lacerata, Tul.; Peridia, clustered, brick colored, 
splitting into numerous segments, thread-like at the top ; 
threads white, spores brick red, scattering freely from 
the fungus, growing in unripe fruit of Amclanchien 
Canadensis. It penetrates the epiderm of the fruit, and 
feeds upon its fleshy part, in fact, when developed, it 
seems to grow from within outward, thrusting its 
filaments thro’ the epiderm, discharging its spores 
abundantly in the form of powder, having a brick-red 
color. The spores are large, oval or rounded, easily 
seen “ individually ” with an ordinary lens. 
*This was brought to me by Mr. W. Gibson, one of our city officiais. He found it growing 
on a chopping block made from a section of a bole of a large birch, 
+This was also brought to me by Mr. Gibson who found it at Bedford Rangc, Halifax, 
growing on twigs ofalder. I sent it to Prof. W. J. Farlow, of Cambridge, Mass., for diagnosis, 
who writes to meas per extract from his letter in regard to it.
