applicable to this form. It is intermediate between Polyporus gilvus 
and Polyporus licnoides, having the same "structure'' (color, setae, 
pores, spores ) as both. It is more hard and rigid than Polyporus. 
gilvus, more thick and rigid than Polyporus licnoides. We believe 
we have among our unnamed collections, made in Cuba, an ample collec¬ 
tion of the same form. It should be entered in Section 96 as a form 
of Polyporus gilvus, 
HYDNUM LUTEOLUM (Pig, 1734).- We believe this to be one of 
the rarest plants of Europe. It appears to have been described first 
in Pries' last work (Hym. Europaei, 1874) and was apparently based 
on Vi liar s' old reference under the misname Hydnum auri scalp ium. 
Pries endorses it ''v.v.' r but it is not included in. either of his 
Swedish lists- and is not in his herbarium. Querist- includes it in 
his book though he never recorded it in his yearly reports. There 
seems to be but one French, record, Vil'lars old record from Prance, 
Both Pries' and Quelet's records were probably based on that. The 
only specimens I have ever seen are in the museum at Paris, mis- 
referred to Hydnum geogenium and from which our photograph was made. 
It is a thin, yellow plant and I believe the only one known of this 
shape, spathulate, tapering to the base. No illustration of it has 
heretofore been given. The spores, if I see them correctly are 
globose, hyaline, smooth, about 4 mic. 
HYDNUM ADTJ3TUM, DIMIDIATE. In 1907 we received from R. 3. 
Mackintosh, Massachusetts, a sessile, thick, brittle Hydnum about 
X 5 inches and -J- cm. thick. We misreferred it at the time for 
we were not expecting a dimidiate specimen of Hydnum adustum. But 
on comparison we can see it is the same plant in its flesh, spines, 
and spores. The surface is more pubescent than the usual plant and. 
it is much thicker. We have a very similar collection from Dr. 
Whetstone, Minnesota. We present (Pig. 1735) the usual stipitate 
form of Hydnum adustum which is quite common in the United States--. 
We have about fifty collections of the usual, thin, stipitate form. 
Rarely Hydnum adustum has its spines coalescenh, resembling superfi¬ 
cially a polypore. We have one such collection from E. B. Sterling, 
New Jersey, and present (Fig. 1736 ) the" hymenial appearance which is 
abnormal. Outside of our country Hydnum adustum is only known from 
Japan. 
HYDNUM GLABRESCENTS' PROM DR. JAMES R. WEIR, CUBA (Pig. 1737 ).- 
We present a photograph of the type and it is doubtful if it is other 
than a thick form of the tropical H3^dnum Rawakense. It is quite rare. 
The only collection we have is the one collected by Morgan many years 
ago and correctly referred, which Banker renamed Hydnum Morganii. 
Berkeley also got it from Ceylon. Hydnum guar an it i com, as named by 
Spegazzini and Hydnum luteo-virens by Cesati, Borneo, which was listed 
Grevillea, VoT. 20, page 2 but does not seem to have been published, 
are both better classed as Hydnum Rawakense, We have the thin, 
tropical form from Burtt Deeper, Salem, Ohio, growing on a wild cherry 
and it is noteworthy that a tropical plant should be found so far 
north. 
POLYSTICTUS EXPANSES FROM J'OHH GOSSWEILER, AFRICA (?i~. 17S8 ) 
We use a name for this proposed by Fries for a plant from Guinea of
