This specimen was sent by C. V. Piper, and collected 
on Abies grandis at Jansville, Idaho. Prof. Piper informs 
me that in that locality the hydnum was quite common 
on diseased Abies grandis trunks and that some ol the 
specimens were much larger than the one sent me. 
It is of exceeding interest being the first woody hydnum 
described, to my knowledge. 
It might well be taken as the type of a new genus for 
which Prof. Ellis suggests the name Echinodontium, if this 
view be accepted, making the name Echinodontium tincto- 
rium, E. & E. 
Prof. Ellis advises me that the plant is evidently the 
same as one he received from the Alaska collection of J. G. 
Swan, but in that specimen the teeth were all broken off at 
the base and their hollow remains were mistaken for pores. 
The plant was described (Bull. Torr. Club, Vol. 22, p. 362,) 
as Fomes tinctorius, E. & E. The rich red color of the sub¬ 
stance of the pileus is very peculiar, and Prof. Ellis states is 
used in Alaska for dyeing. I acknowledge my grateful in¬ 
debtedness to C. V. Piper for this interesting specimen and 
to Prof. J: B. Ellis for aid in its classification. 
3—THE ABNORMAL GENUS 
MYRIADOPORUS. 
In 1884 Prof. Peck described (in Bull. Torr. Club, Vol. 
11, p. 26,) a new genus Myriadoporus, which he stated at 
the time, appeared to him as an abnormal form of Polyporus. 
We found a specimen belonging to this genus this year and 
distributed portions to various mycologists. From a very 
interesting letter received from Prof. Patouillard regarding 
this specimen, I am enabled to present the following points 
regarding the genus. Myriadoporus as described has the 
“Hymenium cellular-porous; pores of the surface shallow, 
open, the others imbedded in the hymenium. The pores do 
not as in Polyporus form vertical parallel tubes, but rather 
cells or short tubes variously directed, so that a vertical sec¬ 
tion of the hymenium as well as a horizontal one is porous. 1 ’ 
Prof. Peck originally described two species, but numerous 
others have since been observed and it is found that they are 
always sterile and are abnormal forms of various Polyporii.
