NOTE 300. Fomes hornodermus, from Dr. J. B. Cleland, Australia. This is a thick,
ungulate specimen, but I note an orange stain under the crust which in our Fomes pamphlet
we held to be a feature of Fomes martius, as different from Fomes hornodermus. Perhaps
Fomes martius is only a thin form of Fomes hornodermus.
Miss Wakefield, in a letter to me, states that she thinks that the Australian Fomes
with the orange tint under the cuticle is Fomes hemitephrus, and not Fomes martius as
I have held it in my Fomes Synopsis.
NOTE 301. Fomes linUtoscaber. from Dr. J. B. Cleland, Australia. To the eye in
every feature, surface, color, context color, pores, this is so much like Trametes strigata
that I thought it must- be a Fomes form of that species. The pores are stratified and it
has setae on the hymenium and belongs to section 70 of the Fomes pamphlet. Trametes
strigata has no setae as far as T can find. When I observed the type of Fomes liniatoscaber,
which is in the British Museum. I thought it a Fomes form of Trametes strigata,
but I find on examination that it agrees with this specimen from Dr. Cleland in having
setae on the hymenium. It is a true Fomes with stratified pores, but was omitted from
my Fomes Synopsis as I was under the impression then that it was only a Fomes form
of Trametes strigata.
NOTE 302. Trametes rosea, from Dr. J. B. Cleland, Australia. Context punky, dry.
pale salmon, (light ochraceous salmon). Pores white, medium, large, ^mm. diameter,
indistinctly stratified, forming imperfect layers in the manner of Fomes annosus. Spores
3x5 mic. hyaline, smooth.
The specimen received from Dr. Cleland is imperfectly developed evidently. It is
largely resupinate with imperfect pileus. The species belongs in the Trametes section
(of 63), considered in our Fomes Synopsis, page 224. It agrees exactly with Trametes
roseola as to context color, but differs from all other species in this section in having
large pores. Its method of pore development is much like Fomes annosus.
NOTE 303. Variations of Fomes senex. A fine series of specimens from C. N.
Forbes, Hawaii, illustrates variations in form and surface of this common, tropical species.
Usually Fomes senex, as described in our Fomes pamphlet, is applanate with long pores
almost reaching the crust. We have many collections of this from the East, Africa, Brazil,
etc. Most of Mr. Forbes' specimens are ungulate, with several layers of shorter pores.
One had uneven surface, due probably to the annual layers overlapping from its position
of growth. All have the usual context color, texture, setae, pores, etc., the essentials of a
species. The spores of one specimen (1075) were abundant, globose, hyaline, 4-5 mic.
guttulate. Rarely we find spores in Fomes senex and sometimes they are deeply colored.
We are unable to explain this spore discrepancy and have already commented on it in
our Fomes Synopsis, page 259.
NOTE 304. Arachnion album, from Dr. L. C. C. Krieger, California. A rare puff ball
everywhere, and this is the first specimen from the Pacific Coast. I have a few specimens
from Ohio, Texas, Mexico, Brazil, Ecuador, Australia, and South Africa. Also one collection
from Italy, which is the only one known from Europe.
NOTE 305. Laternea bicolumnata, from Dr. L. C. C. Krieger, California. This is
the first Laternea known from the Pacific Coast. It grew in garden soil at Chico, Cal.
The species was named from Japan, and this is its first known occurrence in America.
NOTE 306. Polyporus Berkeley! with sclerotium, from B. Leeper, Ohio. We are very
grateful to Mr. Leeper for his aid in solving the problem of the sclerotia of the merismatoid
section of Polyporus. Last month he sent us the sclerotiuni of the rare Polyporus umbellatus.
Now we have a sclerotium of the more common Polyporus Berkeleyi, the sclerotium
of which was, however, as little known. It is a true sclerotium, about two inches in
diameter and five inches long. It resembles a thick rhizome, and is no doubt developed
in the same way. The plant apparently develops its fruit each year from the sclerotium,
and sends out a new sclerotium from which the fruiting body is developed next year.
This is a process similar to the development of rhizomes in flowering plants. In fact the
sclerotia of this group of fungi and the rhizomes of flowering plants are analogous bodies.
Our best thanks are tendered to Mr. Leeper for the specimens illustrating this feature,
and for beautiful photographs.
NOTE 307. Hexagona aloida, from G. R. Lyman, District of Columbia. Developed
on a bamboo flower pot from Manila in a glass house at Washington. This is the only
white Hexagona known, and is widely distributed in the tropics. It takes Lenzitoid forms
also. (Cfr. my Synopsis of Hexagona, page 29, fig. 314).
NOTE 308. Polyporus confusus, from Rev. C. Torrend, Brazil. Cfr. Stipitate Polyporoids,
page 177, fig. 476. Heretofore only known from the type specimen at Kew from
Louisiana.
NOTE 309. Kretzschmania clavus, from Rev. C. Torrend, Brazil. I doubt if there
is really more than one species of Kretzschmania. Thirty-three (alleged) species have
been proposed, but all the specimens I saw and photographed in the various museums of
Europe impressed me as being very much the same. They differ some in the size of the
heads and prominence of the ostioles, but I think they are all virtually the same. The
original species were Kretzschmania caenopus from Cuba and Kretzschmania clavus from
Brazil Both were by Fries (as Sphaeria) and the former had smaller heads than the
latter.' Both, I think, were the same otherwise.
NOTE 310. Polystictus flabelliformis, from Rev. C. Torrend, Brazil. From Southern
Brazil, legit. Rick. This is the first American specimen that I have seen that agrees
