106 SALMON: SUPPLEMENTARY 
“prope lacum argentinum dictum Quillen in Andibus valdivianis, 
vulgatissima.”’ The plant shows these characters: perithecia 90- 
130 # in diameter, cells of outer wall of perithecium 10-15 y wide; 
appendages 5-20, I-1% times, or rarely twice, the diameter of 
the perithecium, becoming thick-walled toward the base when 
mature, apex 4—6 times regularly dichotomously branched, tips of 
ultimate branches recurved ; asci 4~12, 45-55 x 30-35 #4, Spores 
3-5, rarely 6. The fungus is, I feel convinced, merely one of the 
forms of the polymorphous species J/. a/ni, with a much-branched 
apex to the appendages. Quite similar forms are common in the 
United States on several host-plants, ¢ g., on species of Quer 
cus on Menispermum Canadense, Cornus alternifolia, etc. Occa- 
sionally, moreover, in “JZ, Myoschili’’ the apex of the appendage 
is only 4 times dichotomously branched, and the fungus is then 
seen to be identical with the more common form of JZ a/ni. In 
some instances—evidently to be regarded as ‘‘sports’’—an aP- 
pendage occurs which forks from near its base into two wide 
branches, each of which is dichotomously divided at the apex 4 
in a normal appendage. Dr. Neger’s figure (. c., Pl. 28, £7) 
represents the apex of an appendage in an immature condition— 
the tips of the ultimate branches (here shown as straight) become 
revolute at maturity (see P/. 9. f. Zo). : 
In Rehm’s Ascomycet., no. 1117, there is a very interesting 
example of MW. a/nt, collected by Professor P. Magnus on Rham- 
NUS catharticus at Brandenburg, August, 1893. The apex of the 
appendage in many of the perithecia is more branched (see Pl. 9- 
f. rr) than is usual for the species in Europe, and exactly co 
sponds in this respect to certain American forms of J7. alnt o 
Quercus, Cornus, etc., which have by some authors been consid: 
ered as distinct species under the names of JZ. pulchra, M. quercin4, 
etc. The branching of the apex of the appendages in this Bran- 
denburg specimen agrees so closely with that found in « M, My 
chili’ (see above) as to show clearly that the latter must be regard 
as merely a form of MW. alni (cf. Pl. 9. f. To, 17). 
A rather remarkable form of 1. al/ni has been sent by Profes- 
sor Kingo Miyabe on Corylus rostrata var. Sieboldiana from = 
koda Mountains, Prov. Mutsu, Japan (N. Hiratsuka, August eh 
1897).” Unfortunately the fungus is immature. The specimen’.
