to have much smaller tubes and slightly longer spores, which are 
tinged with red at times. It is also very close to old plants of 
C. perennis collected in autumn. Additional collections should de- - 
cide whether it is a good species or only a variety, as it was first 
considered by Peck. 
Coltriciella gen. nov. 
Hymenophore small, annual, tough, epixylous ; stipe attached 
to the vertex of the pileus ; surface of the pileus anoderm, zonate ; 
context spongy, fibrous, ferruginous, tubes angular, one-layered, 
dissepiments thin ; spores ellipsoidal, smooth, ferruginous. 
The type of this genus is Polyporus dependens B. & C., a very 
rare plant found thus far only on dead pine logs in South Carolina 
and New Jersey. In some ways it resembles the genus Porodiscus, 
the species of both being small and epixylous with vertically 
attached stipes, but the two genera are very distinct as regards 
more important characters, such as the structure of the context 
and spores. From Coltricia, its nearest ally, the present genus 
differs chiefly in being uniformily epixylous and in having a pend- 
ant vertically-attached pileus. The name I have chosen refers to 
its general resemblance to Coltricia, this resemblance being best 
seen in Coltricia cinnamomea, which grows very frequently on 
wood in a state of advanced decay. Only one species is known.

This very rare and interesting little fungus was first collected 
by Curtis in South Carolina on decorticated pine wood lying on 
the ground. It has since been found at Newfield, New Jersey, 
once under a decaying oak log and twice on a dead pine. The 
first of these collections on pine seems to have been quite abundant, 
since there are still in the Ellis collection about twenty-five speci- 
mens of it. Ellis says that they grew from the upper surface of 
the hollow in a rotten log, where they were found on July 3°, 
1883. On April 21, 1890, Dr. F. W. Anderson discovered a few 
plants growing on a rotten pine knot near Newfield. Iam inclined 
to think that the collection made under the dead oak log was 
really growing on chips or sticks of pine.
