192 SALMON : SUPPLEMENTARY 
lovia—on B., viscidiflora (B. Douglasit), Willis, Montana, U. S. A. 
(F. W. Anderson, Oct. 1888), and on Sigelovia sp., Laramie 
Hills, Wyoming (E. Nelson, September 28, 1897). I have already 
remarked on the peculiarities of the form on Aizgelovia (see mono- 
graph, p. 203). This South American plant on Euphoria, while 
much recalling the Old World species Z. taurica Lév. in habitat, 
and in the large size of some of the perithecia and asci, yet clearly 
belongs to £. cichoracearum, and exactly matches the large form 
of this species found on Arctium in Europe. 
The fungus recorded by Hennings (30) as “‘ Z. /amprocarpa” on 
Bigelovia sp. from “ Snow Mount, 7,000 ft., California” is accord- 
ing to a specimen collected by Purpus and labelled ‘“ California 
7,000 ft.” (in herb. Jaczewski) £. polygoni var. sepulta. 
Spegazzini ('79) has recorded “ E. umbelliferarum” (= E. poly- 
gont) on Bowlesia tenera from Flores near Buenos Aires, and in the 
diagnosis has described the spores as measuring 25-40 4 long X 
14-18 » diam.” Professor Spegazzini has sent me a specimen of 
the plant (labelled “4. wimbelliferarum var. platensis’’), which 
proves to be &. cichoracearum. The few spores seen by me meas- 
ured about 24 x 14y. The fungus recorded by Spegazzini (79) 
as “ £. lamprocarpa”’ on Tagetes glandulifera proves to belong to 
E. galeopsidis. 
The records by Bubak (10) of £. cichoracearum on Verbascum 
phlomoides and V. Lychnitis (and probably also that on Blattaria) 
from Bulgaria belong to Z. taurica. Professor Oudemanns writes 
to me that his record (Rév. Champ. des Pays-Bas, 2: 94. 1897) 
of ‘ E. lamprocarpa”’ on Verbascum thapsiforme was based merely 
on the occurrence of an Ozdiumm stage on this plant. 
I have stated in my monograph (p. 202) that the Exysiphe oc- 
curring on Achium and Anchusa, although commonly referred to 
£. cichoracearum, has always proved in my experience to be E. 
polygont. I have, however, since found in Professor Jaczewski's 
herbarium, a specimen on Achium vulgare (“ St. Lubin-de-la-Haye 
Eure-et-Loire, France”) which is true £. cichoracearum (with 
regularly 2-spored asci, etc.). On Anchusa, however, the fungus 
in all the examples I have seen, belongs to &. poly goni—good 
specimens on this host are to be found in Syd. Myc. March, n9- 
655.
