Ustilago arenariae Ell. & Ev. on Arenaria congesta from 
Colorado is certainly not an Ustilago but has the appearance of 
ascomycetous spores merely mechanically adhering to the host. 
Ustilago cyanea, parasitic on Balsamea vulgaris, was found in 
California by Harkness and made the basis of anew genus, Spo- 
rophaga, with possible relationship to the Uredineae or Ustila- 
gineae. It may possibly belong with the Chytridineae but cer¬ 
tainly not with the Ustilagineae. Ustilaginoidea oryzae (Pat.) 
Bref. has been reported in this country on imported rice seed. 
Brefeld’s later work has shown that this genus does not belong 
with the Ustilagineae. Ustilago flavo-nigrescens B. & C. on 
Scleria sp. from Cuba and Ustilago viridis Ell. & Ev. on Setaria 
sp. from Louisiana appear, from an examination of authentic 
specimens, to be the sclerotial stages of species of Ustilaginoidea, 
the latter probably being the same as Ustilaginoidea setariae Bref. 
These species are therefore excluded. Ustilago ficuum on figs 
and Ustilago phoenicis on dates, both not uncommon in markets 
and Ustilago fischeri on kernels of corn (reported from Jamaica) 
are now known to be species of Sterigmatocystis. Sorosporium 
borrichiae Ell. & Ev. on Borrichia argentea from the island of 
Cozumel, off Yucatan, has been examined by the writer and like¬ 
wise seems to be a species of Sterigmatocystis, appearing on the 
host apparently because the flower heads were dried under unfav¬ 
orable conditions of moisture. Ustilago gynerii Vize on Gy- 
nerium argenteum from California was long ago shown to be a 
species of Gymnosporium. Entyloma alsines Hals, on Stellaria 
media from New Jersey seems not to be an Entyloma, at least a 
careful examination of the type material in several exsiccati and 
that received especially for examination failed to show any spore 
stage except the Cercospora-like conidia on the surface of the 
leaves. The writer is indebted to Bresadola for type material 
of Doassansia sintensii Bres. on Cedro matchos from Porto Rico. 
This is certainly no Doassansia. The diseased leaves are coria¬ 
ceous and therefore not of the type infected by this genus; 
besides this, the discolored spots show nothing to indicate defi¬ 
nitely what caused them. Doassansia zizaniae on old stems of 
Zizania aquatica and Burrillia globulifera occurring on similar 
parts of Glyceria fluitans, both described by Davis from Wis¬ 
consin, do not seem to be true Ustilagineae but are more prob¬ 
ably sclerotial stages of species of Ascomycetes. Ustilago osmun- 
dae Pk., reported on Osmunda regalis first from New York and 
later from other eastern states, probably belongs with the Hypho- 
mycetes instead of the Ustilagineae. This curious species needs 
further study. Ustilago panici-miliacei (Pers.) Wint. has been 
reported erroneously in this country, having been confused with 
Sorosporium syntherismae. 
Sphacelotheca has been extended by the addition of a num¬ 
ber of species usually placed under Ustilago. A few species have
