May 1905] Notes on Fungi II. New Species 
113 
Sori in ovaries subglobose or oblong, 1.5-2 mm. long, covered 
by a greenish, smoth membrane which upon rupturing exposes 
a black granular spore mass; spore balls.black, opaque, globose 
to oblong and often irregular and angled, firm, composed of many 
spores, 80-235 fx long; spores lighter colored, globose to subglo¬ 
bose, adhering by dark folds in the outer memberane which on 
separating give the spore an echinulate or tuberculate appearance, 
7~i2fx diam. 
On Homalocenchrus hexandrus (Sw.) Kuntze. Type de¬ 
scribed from specimen in the herbarium of L. R. Tulasne in the 
Paris Museum, collected by Letourneux in Algeria, Aug. 1862. 
Also collected by F. M. Bailey, Brisbane So. Australia; Elihu 
Hall No. 760, Mumford, Tex., June 8, 1872 and T. H. Kearney 
No. 41, Mobile Ala., July 5, 1895. 
Only the last two collections have been examined but the 
full descriptions and figures leave no doubt as to the identity of 
the species. McAlpine, Syst. Arr. Austral. Fungi, 186, 1895, 
reports Thecaphora inquinans B. & Br. as on the above host 
but it was originally found on Paspalum and is probably an 
erroneous determination. 
UREDINALES. 
Puccinia ACTiNGMERiDis Magnus. — This species was de¬ 
scribed by Dr. Magnus as being found on Actinomeris squar- 
rosa, along the Potomac River near Washington, D. C., Oct. 
1897. A careful search of the region during the fall for the 
last three years failed to reveal any Actinomeris squarrosa, which 
is now caller Verbesina alternifolia, with rust on any part of the 
plant. Verbesina occidentalis however is very abundant in the 
region covered by Dr. Magnus on the trip on which the above 
v/as collected and it is usually badly rusted. This fact led me to 
be suspicious of the determination of the host and of the value 
of the species. I have not been able to verify this suspicion until 
recently when Mr. E. W. D. Holway was kind enough to 
send me some fragments of the flower from type material dis¬ 
tributed in Vestergren, Microm. Rar. Select. No. 380. Verbesim 
alternifolia nearly always has winged achenes which Dr. Magnus’ 
specimen does not have. The material of this collection in the 
Department Herbarium has been with a lot of undistributed 
material for some time and not easily accessible, but after hunting 
over several hundred envelopes it was found. The envelope con¬ 
tained enough of the plant to show that its branches and leaves 
are opposite which is never the case in V. alternifolia. The ma¬ 
terial is positively Verbesina occidentalis, the rust on which is 
considered by most mycologists to be Puccinia verbesinae Schw. 
Mr. Holway was also of the opinion when he sent me the material 
that Dr. Magnus’ species could not be distinguished from Puc¬ 
cinia verbesinae Schw.
