202 SALMON : SUPPLEMENTARY 
numbering several hundred specimens—in the Kew herbarium. 
The evidence obtained from the examination of these specimens 
(which come from all parts of the world) forces me to conclude 
that ‘‘ P. clavariaeformis”’ is not a distinct species from P. corylea, 
and further that it is impossible to give specific value to such char- 
acters as the shape, size, etc., of the penicillate cells. The shape 
of the penicillate cells, in ‘‘ P. clavariaeformis’’ is shown at pl. 70, 
f. r-6, drawn from specimens (now in the Kew herbarium), 
on Embothrium coccineum, sent by Dr. Neger. Most of the cells 
are branched in a more or less ‘“‘clavarioid’”’? manner as described 
by Neger, but intermixed with these there occur not uncom- 
-monly apparently fully grown cells which are scarcely branched 
at all. (See figs.) In two specimens of the fungus called P. 
Antarctica by Spegazzini on Ribes Magellanicum—one from “ Car- 
ren-leofi, Patagonia andina, January, 1900 (Spegazzini),”’—the 
other (leg. P. Dusén, May, 1896) sent by Dr. Neger from Dr. 
Rehm’s Herbarium,—the penicillate cells are formed as shown 
at pl. ro, f. ro-12. The majority of the cells show a ‘“clava- 
rioid” branching like that found in “ P. clavariacformis,’ and 
mixed among these simple or only slightly branched cells occas- 
ionally occur. In a third specimen, also on R. Magellanicum of 
“ P. Antarctica” from ‘“ Lion Range, nr. Gregory Bay, Patagonia, 
April 20, 1882 (Spegazzini)”—the type locality—the penicillate 
ceils are quite as much branched (see f/. ro, f. 7-9) as in 
“P. clavariaeformis,” so that were the plant possessing penicillate 
cells with ‘‘clavarioid” branching to be kept distinct from fF: 
corylea, it would have to bear the oldér name of P. Axtarctica 
Speg. Dr. Neger writes to me that he is now of the opinion that his 
“P. clavariaeformis”’ is identical with ‘“P. Antarctica.” Ina speci- 
men labelled P. corylea from “ Puente de Vapas, Andibus Mendo- 
zinis, 2,500 m. alt., March 2, 1901, in foliis vivis Adesmiae sp.,” 
sent by Professor Spegazzini. 1 have found after examining some 
thirty or forty perithecia only unbranched penicillate cells (see pl. 
zo, f. 13). This is interesting as Neger has referred (52) 4 
Phyllactinia on Adesmia sp. to “ P. clavariaeformis.” We must 
conclude, therefore, that on the same genus of host-plants, ‘if not 
on the same species, the penicillate cells of Phyllactinia are some- 
times simple and sometimes branched. An example on Excoecaria
