Graves: Parasitism in Hymenochaete Agglutinans 283 
Hymenochaete agglutinans was described in 1874 by Ellis 3 as 
follows: “Of rather loose texture and of a light yellow color at 
first, becoming firmer and of a light tan color or rufous tint as the 
bristles are developed; closely adnate with a determinate margin, 
which is tomentose at first ; forming orbicular or elongated patches 
or sometimes entirely surrounding the twig or limb on which it 
grows for an inch in length. 4 Common in autumn in swampy 
thickets on Andromeda , Vaccinium, etc., without much discrimi- 
nation, fastening the stems or branches together wherever a dead 
twig or branch lies in contact with a living one : turns black and 
dries up during the winter.” 
Peck, 5 a few years later, reported the same species “ on trunks 
and branches of living alder trees. Sandlake, and Adirondack 
Mountains.” (New York.) 
Saccardo, 6 in 1888, recorded the species, stating that it was 
indigenous to North America, and citing the collections of Ellis 
and Peck. 
Later, Massee 7 included the species as indigenous to the United 
States in his monograph on the Thelephoreae, remarking as fol- 
lows : “ A well marked species, and certainly a genuine Hymeno- 
chaete. . . . Often completely surrounding twigs or cementing 
two together by growing continuously around both. Hymenium 
pale but often bright yellow, with ferruginous shades due to the 
setae.” 
We find the same species also recorded by Longyear 8 as com- 
mon on oak limbs in Michigan. 
A careful search through the literature has failed to disclose 
any definite record of parasitism in this species. Ellis’ descrip- 
tion, of course, points to such a relation where he speaks of fast- 
ening a dead twig or branch to a living one, and Peck also notes
