hosts, that Professor SARGENT informs me that the determinations 
above given are confirmed by HEMSLEY, who suggests that the 
var. uliginosa should be considered a distinct species. : 
I saw no other species of Taphrina during-my stay at Punta 
Arenas, nor did I find indigenous species elsewhere in Chile. About 
Santiago and in the central valley, where the Lombardy poplar is 
extensively planted, attaining a great size and forming one of the 
most conspicuous features of the landscape, the brilliant T. aurea 
was common, attacking the leaves of this host. TJ. Ulmi was also 
abundant on an introduced species of Ulmus planted about the 
Bafios de Apoquindo, near Santiago; and throughout this whole 
region of the central valley: the familiar T’. deformans is destructive 
to the peach. 
The Taphrina on Nothofagus, to which I have given a name 
suggested by the peculiarities of its spores, may be characterized 
as follows: 
Taphrina entomospora, nov. sp.—Stratum ascorum livide-al- 
bidum, totam paginem inferiorem folii occupans, mycelio inter 
cuticulam et epidermidem nascente ortum: ascis dense confertis, 
subcylindricis, apice rotundatis vel subtruncatis, cellula basali 
latiore instructis; supra epidermidem positis: sporidiis entomo- 
morphis, octonis, plasmate dense granuloso obscuratis; primum 
simplicibus, ovalibus; deinde appendiculatis, appendicibus biformi- 
bus; alteris utrinque terminalibus, rectis, cylindraceis vel subclava- 
tis; alteris subterminalibus, saepissime quaternis, rigidis, tenuibus, 
divergentibus, subcurvatis, subattenuatis, utrinque cyclo oriundis: 
_ ascis §5—60X13—15 #. Sporidiis g—10X3—4#. Appendicibus 
_ terminalibus 8—123.5 #, subterminalibus 15—25Xo.8 #.

My first day’s foray yielded another remarkable fungus, associ- 
ated with the Taphrina just described. While gathering material 
of the latter, I noticed that in some instances the leaves were covered 
by a glistening powder, and further examination showed that 
when the Taphrina occurred on twigs growing protected among the 
dense branches of small bushy trees, the powder was associated with 
Teddish-brown perithecia evidently belonging to one of the Ery-
