NoTES ON THE ERYSIPHACEAE 101 
Fla. (coll. H. H. Hume). It is an interesting form of the species, 
the perithecia possess few (7-12) rather short appendages, very 
unequal in length on the same perithecium, and scarcely swollen 
at the apex. 
“U. Zelkowae P. Henn.” is described (31) as follows: ‘‘ am- 
phigena ; mycelio arachnoideo, tenui, evanescente, albido ; perithe- 
ciis gregariis, subglobosis, atris, 100-120 #4, appendicibus radiatis, 
simplicibus ca. 20, hyalinis, apice convolutis usque ad 10 + incras- 
Satis, 100-200 ys longis, 5—7 » crassis ; ascis (3) ellipsoideis vel sub- 
Ovoideis, 3-4-sporis, 35-50 x 30-40 4, basi vix stipitatis ; sporis 
ellipsoideis utrinque obtuse rotundatis, 1-guttulatis, hyalinis, 18— 
22X 12-15 uw. Tokyo; auf lebenden Blattern von Ze/kowa acumt- 
ata Pl. (Kusano, no. 15 3, Oct. 1, 1899).”’ The diagnosis here given 
shows that the fungus is the same as that sent to me from Kobe, 
Japan, on Zelkova acuminata (Z. Keak), by Professor Kingo 
Miyabe. This I have described in my monograph, p. 110, and 
have given there my reasons for considering it only a small form 
of U. Clintonii.

Distrib. add: S. America, Uruguay, Argentine Republic, 
Tucuman and Salta (79). 
flosts, add: Celtis Boliviensis (79), C. Selloviana (61), C. 
Stnensis, 
In some examples of this species sent by Spegazzini from 
Uruguay on Celtis tala many of the perithecia attained a diameter 
of 390 y, and contained from 150-175 asci each. 
“U. Shiraiana P. Henn.” is a form with 2—-4-, or very rarely 
S-spored asci. It is not, I consider, distinct from U. polychaeta 
(see “ Erysiphaceae of Japan,” 68, p. 439). Phyllactinia corylea, 
st usually possesses bisporous asci, shows much the same 
‘aration as the present species (see under that species).
