Bot. Ges., vol. x, Heft 2, Berlin, Mar. 23,1892, pp. 57-63, figs. 2. 
A revision of the genus Diorchidium and a discussion of several of the species formerly 
described by Magnus. The author's opinion is that while the genus Diorchidium is prob¬ 
ably not tenable, because there are transition fo as into Pucdnia, he would nevertheless 
retain it for the present, because the distinction between other genera ( Uromyces and Puc- 
cinia) are quite as artificial. For the present, therefore, he would include in Diorchidium 
species in which the majority of the spores have the septum perpendicular upon the pedicel. 
The genus Sphenospora is, however, established by the author for Diorchidium pallidum , 
much on account of the differences in the development of the spores. It is characterized by 
having no endospore and consequently no gerni pores are formed before germination. Onlv 
when germination has taken place are the places indicated through which the contents of 
the spore has come out. (T. H.)

pp. 94-95. 
The author states the discovery of Gymnosporangium confusum in the vicinity of Bremen. . 
It has been shown by culture that this fungus developed abundant aecidia upon Cratcegus 
oxyacantha. According to Dr. Focke, this fungus has existed near Bremen since 1860. 
There had been planted a number of varieties of Cratcegus that were badly injured by a 
Rcestelia , while numerous pear trees in the same garden did not show any sign of fungous dis¬ 
ease. (T. H.)

men, May, 1892, pp. 361-376. 
Ninty-six species of fungi are known from the vicinity of Bremen, among which Puc- 
cima is represented by 43, Uromyces 11, Melampsora 9, and some others scarcely atall. The 
paper contains remarks upon some of the important forms, such as Lagenidium, Syncytiorum 
n. sp. ad interim of the family Ancylistacece. This fungus is merely known in the spor¬ 
angium form and occurs in (Edogonium boscii. A new variety of Pucdnia perplexans 
is described, namely, arrhenalheri, found upon Arrhenatherum clatius and a variety, cortici- 
cola , of Phragmidium rubi. Peridermium pini is rare in the northwestern parts of Germany, 
and the author mentions that the teleutosporicfonn is still unknown. The spermogonia of 
Peridermium showed some differences when the fungus has been taken from Pinus strobus 
or P. sylvestris. Those of the last do not cause any swelling of the branches and they are 
only visible when the bark has been removed. They then show as yellow spots, but the 
microscopic structure is almost the same as in P. strobi The peculiar odor observed in the 
spermogonia of P. strobi was not found in P. pini. (T. H.)

Discusses the connection between cedar apples and rust of fruit trees. Mentions species 
found in Connecticut and describes development. Notes experiments to determine the life 
history of the “bird’s-nest” form and describes as a new species Gymnosporangium nidus- 
avis (see No. 310). (J.F. J.)

I he most remarkable thing about (he species is the symbiotic relation between its myce¬ 
lium and unicellular algae (Chroococcaceae) which the author has described. (M. B. W.)
