NOTES ON THE ERYSIPHACEAE 197 
finger-like processes. They have been studied in detail by Grant 
Smith (77), and well figured. (See p. 4.) 
E. TORTILIS (Wallr.) Fr. (Monograph, p. 213) 
Syn. add: Trichocladia tortilis (Wallr.) Neger, Flora, 88: 351. 
1901. 
Distrib. add: Bulgaria (10). 
The record of the occurrence of £. tortilis on Thalictrum aquile- 
&ifolium by Massalongo (50) was due to an error of identification, 
the fungus in specimens sent to me proving to be Z. polygoni DC. 
Professor Oudemanns writes to me, with regard to his record (Rév. 
Champ. des Pays-Bas, 2: 95. 1897) of £. tortilis on Cornus alba, 
that “the leaves of the Cornus, examined with more care, prove 
not to belong to C. a/ba, but to another garden. species, unable to 
be identified.” 
E. raurica Lévy. (Monograph, p. 215) 
Distrib. add: Bulgaria. 
Flosts, add: Cerinthe (80), Dorycnium herbaceum (80), Marru- 
bium peregrinum, Saussurea sp., Verbascum Lychuitis. 
The example on Marrubium peregrinum from Bulgaria is re- 
corded by Bubak (10) as £. ga/eopsidis, but from a specimen (now 
in the Kew herbarium) sent by the author the fungus proves to 
be E. taurica, Similarly, the fungus on Verbascum phlomoides 
and V. Lychnitis, referred by the same author to £. cichoracearum 
Proves, from specimens sent (now in the Kew herbarium) to 
belong to &. taurica. The same is also probably the case with the 
. fungus on / Blattaria, referred also to E. cichoracearum, but the 
Specimen sent is too immature to permit of certain identification, 
although the habit-is that of F. taurica. The record by Brunaud 
(Actes Soc. Linn, Bordeaux, 32: 155. 1878) of the occurrence of 
&, faurica on Cnicus lanceolatus from France proves to be erro- 
_ fheous, the fungus proving, from a specimen sent (now in the Kew 
herbarium), to be &. cichoracearum. Dr. Hennings has sent me 
from Rabenhorst’s herbarium a specimen of the fungus recorded 
(59) as Sphaerotheca Castagnet Lév. on Euphorbia ‘am Berge 
Kellal in Sud-Persien, 10,000’ s. m.’’. The species proves to be 
£. taurica, Another specimen sent from Rabenhorst’s herbarium
