1915 Excerpt: ...be made at present. It should be borne in mind,
however, that the position of the species remains doubtful so long
as the full life history is not known. It may be assumed that
pycnia and primary uredo may occur in a region where teliospores
are produced, but when teliospores are absent and the reproduction
is by secondary uredo there is no possibility of pycnia occurring.
The two species of Ficus rust described in N. Am. Flora (7: 103.
1907) are here united. It was found in carefully studying the ample
collections by Dr. Stevens that they showed great variation in size
of spores and development of paraphyses. Upon comparing data from
all sources available there remained no doubt that only one species
is represented, whether paraphyses with thick or thin walls are
present in full development or practically absent, or whether the
spores are larger or smaller, etc. The genus Kuehncola is here
associated with Physopella, Phakopsora, Pucciniastrum, etc., in the
Uredinaceae, instead of with Phragmidium in the Aecidiaceae, as
heretofore. The change is made on account of the evident
unpedicelled, catenulate teliospores, corresponding to those of
Melampsoropsis and other genera of the former family, but clearly
alien to the Aecidiaceae. 6. Kuehneola Gossyp11 (Lagerh.) Arth. N.
