Freeman (20) has recorded ‘ E. communis’’ on Eupatorium 
ageratoides L.(Hennepin, Oct. 1893. Sheldon 4083). The author 
kindly sent me part of the original material (now in the Kew 
herbarium), and I have found that the fungus is the EArysiphe with 
lobed haustoria which I have referred at p. 208 of my monograph 
with some doubt to £. galeopsidis. In the present case, as in the 
two other examples mentioned in my monograph (J c.), the asc 
agree with those of £. galeopsidis in not containing spores on the 
living plant. &. cichoracearum with normal bisporous asci occurs 
on Eupatorium cannabinum, E. perfoliatum, and E. purpureum, and 
it is certainly very interesting to find on one species of the genus, 
viz.: E. ageratoides, a fungus constantly possessing lobed haustoria 
and asci without spores—a combination of characters only found 
in £. galeopsidis. 
Professor Spegazzini has sent me a specimen (now in the Kew 
herbarium) of the Erysiphe recorded (79) by him as “&. lampro- 
carpa (Wallr.) Lév.” on Tagetes glandulifera (=T. minuta) from 
Lincoln, Argentine Republic, Sept., 1899. On examining this 
fungus I found that the asci, although the perithecia in color, etc., 
_ appeared ripe, contained no spores, and on searching the myce- 
lium for haustoria it was found that these were, for the most part 
at any rate, distinctly lobed (see p/. 9, f. 13). The fungus con- 
sequently must be referred to E. galeopsidis. The host-plant ™ 
the above case belongs to the Compositae and on this account the 
record is of special interest. 4. galeopsidis had been supposed to 
be confined in its range of host-plants to genera belonging t0 the 
Labiatae and to Chelone in the Scrophulariaceae until the existence 
of an Erysiphe with lobed haustoria and asci without spores was 
discovered on Eupatorium ageratoides (see paragraph above). We = 
have now an instance of the occurrence in South America of the 
same fungus on another genus of Compositae.
