men received from Delastre and marked by the latter “graveo- 
lens,” which is identical in character with the plants that we have 
regarded as typical of the present segregation. Two other speci- 
mens received from Delastre and marked “ hydnum fragrans Dtr ” 
are of precisely the same character. In Fries’s herbarium at 
Upsala is a specimen undoubtedly received from Delastre, which 
is marked “hydnum fragrans. 29Dstre. 1823. hydnum leptopus 
var. V. graveolens Pers. Myc. Eur. Sect. 2. p. 171.” This is ap- 
parently Delastre’s hand. In one corner of the label is written 
in a different hand “ graveolens Hym. Eur. p. 606.” It seems 
highly probable that this specimen should be regarded as the type 
of H. graveolens Delast, as published by Fries in Epicr. loc. cit. 
The specimen has the characters of the forms here considered 
except the upper surface of the pileus is more pubescent, in this 
respect approaching the character of P. amicus (Quel.). 
The two species, P. amicus (Quel.) and P. piillus (Schaeff.), 
as we have defined them, are closely connected by intermediate 
forms, and it seems altogether probable that Fries based H. 
graveolens Delast, on some such intermediate form as the one 
cited above from Delastre and now at Upsala. As a consequence, 
there has arisen the prevailing confusion concerning the latter 
species. It is difficult from the evidence at hand to decide in 
which of the two segregations PI . graveolens Delast, ought to be 
included. On the basis of Fries’s figure and Delastre’s specimens 
we consider the species as synonymous with P. pullus (Schaeff.). 
Opposed to this, however, is the fact that H. melaleucum Fr. is 
unquestionably a synonym of P. pullus (Schaeff.), and Fries dis- 
tinctly asserts that H. graveolens Delast, is distinct from PI. mela- 
leucum Fr. The only point of difference that he mentions that 
seems to have any weight is the softer substance attributed to 
H. graveolens. This is the character that points toward P. amicus 
(Quel.).
