even in his leones volume. Since it is contrary to the laws promul¬ 
gated by our learned "law-makers" to recognize Persoon, we presume 
it is too late to dig up the name. Nor would it be advisable if it 
were legal for the "serpentine" arrangement of one specimen does not 
■make a species. We do not see, however, how Mr. Murrill who worships 
only the "sacred rights of priority" should not have used it, except¬ 
ing perhaps he did not know the species when he saw the specimen at 
Paris. We present, Pig. 1809, a photograph of Mr. Chipp's specimen 
which is in close accord with Persoon's figure. 
POLYPORUS (GAn. ) OPACUS FROM JAS. R. WEIR, CUBA (Fig. 1810).- 
This is the fifth collection known and the first we have received of 
this peculiar and rare species. Montagne named it from Brazil in 
1849 but neither Spruce nor Uhl nor Rick nor Torrend nor any of the 
recent collectors have refound it in Brazil where it must be wonder¬ 
fully rare. However, four collections have been made in the West 
Indies. One at Paris and this one from Dr. Weir from Cuba and one 
from Porto Rico and one from Jamaica at New York. It is a true 
Ganodermus section notwithstanding its mat surface and peculiar spores 
which are more strongly asperate than any other of the section or any 
other Polyporus for that matter known to me. We gave an account of 
the plant on page 106 of our Stipitate Polyporoids. The specimens 
at Paris have been sliced and did not make good photographs. Dr ' . 
Weir's specimen is mashed and the two beautiful collections at New 
York we neglected to photograph. Hence we present a figure of the 
Cuban collection at Paris which is not satisfactory. 
Notwithstanding this most strongly marked species can not 
be confused with any other, Mr. Murrill failed to note it on his 
fugitive trips to Paris and discovered it was a "new species", 
Polyporus flavoporus. He put it in the section Amaurodermus, and it 
is not the only case where he has failed to grasp the recognized 
difference between the sections Amaurodermus and Ganodermus. Dr. 
Weir's specimens "grew on a tree trunk" at Guantanamo, Cuba. I was 
under the impression that the species grew in the ground. 
POLYPORUS (GAN. ) LEUCOCREAS FROM HUNTER, TROPICAL AFRICA 
(Fig. 1811).- With very much the aspect of Polyporus lucidus this 
impresses me now as quite different, although when I saw the type I 
thought it was Polyporus lucidus with pale context. It is a small 
species with the laccate surface of lucidus, a slender, mesopodial 
stipe and white context and very pale spores. The spores, 6X8, 
were described as lightly punctulate but they appear to me decidedly 
rough, though Atkinson claimed that the rough spores of Ganodermus 
section were an optical delusion. We believe from our photograph 
and the character of the white context there will be no trouble in 
recognizing this species in future. It was named as Ganodermus leuco- 
creas, hence for those who use Ganodermus as a sectional name it be¬ 
comes a duplicate in Polyporus, there being a Polyporus leucocreas 
proposed by Cooke. As it is a synonym, however, there will be no 
further use for it excepting as a bar to again use the name according 
to that exceedingly useful rule (for name jugglers) "once a synonym, 
always a synonym".
