348 Murrill: Polyporaceae of North America 



to have much smaller tubes and slightly longer spores, which are 

 tinned 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 Poly horns dc pendens 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 cinnamomca, 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 30, 

 1883. On April 21, 1890, Dr. F. W. Anderson discovered a few 

 plants growing on a rotten pine knot near Newfield. I am inclined 

 to think that the collection made under the dead oak log was 

 really growing on chips or sticks of pine.
