Report of the State Botanist.
Cylindrosporium Acori n. sp.
Spots numerous, subelliptical, sometimes confluent, blackish,
nuclei minute ;
spores amphigenous, forming minute tufts, white,
oblong or subcylindrical, sometimes narrowed toward one end,
.0004 to .0008 in. long, about .00010 broad.
Living or languishing leaves of sweet flag, Acorus Calamus.
Sandlake. September.
The spots, in size and shape, resemble those of Uromyces
2)yrifor7nis. They are sometimes slightly whitened in the center
by the confluence of the tufts of spores.
TJrocystis Waldsteiniae n. sj).
Sori large, oblong, following the nerves of the leaf, commonly
near the margin and nearly parallel to each other, surrounded
by the ruptured epidermis, black; spores not easily separable,
three to six or more in a glomerule, the central and peripheral
similar, subglobose or elliptical, often angular, .0005 to .0006 inch
long, .0004 to .0005 broad, the glomerules very unequal in size
and in the number of component spores.
Living leaves of barren strawberry, Walddeinia fragarioides.
Alcove. June. C. L. Shear.
This species is apparently closely allied to U. Filiycndulin. It
seems to connect TJrocystis with Thecaphora and to be ambiguous
between these two genera. When there are but three spores in a
glomerule the central one is usually larger than tlie others.
Specimens of this fungus have also been received from Pro-
fessor Dearness, of London, Canada.
Cryptospora Goeppertiana Kuhn.
Living stems and branches of Canadian blueberry, VacGmmm
Canadense. Fulton Chain. August. Also on the same host
and on s\vam]i blueberry, Vaceiniuvi corymhosum. Sandlake.
September.
This fungus is destructive to its host. The affected branches
appear to live but one year. Their leaves are dwarfed in size or
wholly obliterated, the branches themselves are generally unnatu-
rally multiplied, and appear to form tufts or clusters, and they
are unusually thick or swollen and their tissues greatly changed.
Sometimes they are much twisted, curved or contorted, but more
