rella ephedrae on Ephedra from Japan; Trametes hydnoides on tree from Venezuela; 
Uredo oncidii on orchid from Mexico; Ustilago bromivora on Bromus from Argen- 
tina; U. vaillantii on cipollino from Morocco; U. vriesiana on eucalyptus from 
Portugal; Valsa leucostoma on apple from France; and Vermicularia phlogina on 
phlox from Canada, 
Among the fungi that were only partially determined because they did not seem 
to fit species known to occur on their hosts were Ascochyta sp. or Stagonospora sp. 
with spores unlike any of the described species, found on Vicia fava pod from 
France; Cercospora sp. (no species reported on host) on Chamaesenna reticulata 
from Mexico; Coniothyrium sp. (perhaps C. oryzae but spores narrower than in 
description) on rice hulls from Puerto Rico; Coryneum sp. (no species reported on 
host) on Pyracantha sp. foliage from Canada; Cryptostictis sp. (no species reported 
on host) on Brabejum stellatifolium from New Zealand; Cytospora sp. (no species 
reported on orchids) on Epidendrum sp. from Mexico; Cytospora sp. (no species 
reported on peonies) on Paeonia moutan from Japan; Diatrypella sp. (no species 
reported on host) on Polyscias guilfoylei from Bermuda; Didymella sp. (no species 
reported on peonies) on Paeonia moutan from Japan; Didymosphaeria sp. (no 
species reported on peonies) on P. moutan from Japan; Didymosphaeria sp. (no 
species reported on host) on Freesia sp. from Netherlands; Gloeosporium sp. (spores 
too long f or G. oncidii) on Oncidium pulvinatum from Brazil; Gloeosporium sp. 
(spores too small for G. laeliae) on Laelia purpurata; Gloeosporium sp. (spores too 
small for either of species reported on Stanhopea) on Stanhopea sp. from Mexico; 
Gymnosporangium sp. (unlike species reported on host) on fruit of Sorbus sp. from 
Poland; Helminthosporium sp. (similar to unknown species previously found on 
tomatoes) on Physalis sp. from Mexico; Marsonia sp. (no species reported on host) 
on Sophora secundiflora from Mexico: Melanconium sp. (unlike described species) 
on Cymbopogon citratus from Puerto Rico; Pestalozzia sp. (no species reported on 
host) on Brabejum stellatifolium from New Zealand; Pestalozzia sp. (apparently un- 
described but previously intercepted on orchids from. Guatemala) on Epidendrum 
sp. from Mexico; Phoma sp. (apparently not reported on host) on Galanthus sp. 
from Netherlands; Phyllosticta sp. (unlike species reported on host) on Codiaeum 
sp. from Bermuda; Pleospora sp. (no species reported on host) on Pyracantha sp. 
from Canada; ScleroHum sp. (sclerotia unlike those of S. gladioli) on Gladiolus sp. 
from Netherlands; Sclerotium sp, (unlike species reported on host) on Allium 
sativum from Syria; Septonema sp. (may be S. orchidophilum but description does 
not mention the small connecting cells between spores) on Cattleya deckeri from 
Canal Zone; and Uredo sp. (apparently undescribed) on Tournefortia sp. from 
Wake Island. 
Diseases found on seeds included ? Ascochyta sophorae on Sophora sp. from 
China; Ascochyta sp. on Pyrethum roseum from England; Cephalothecium roseum 
on Zea mays from Argentina; Claviceps paspali on Paspalum sp. from Costa Rica; 
'Coniothyrium sp. on Jacaranda from Mexico; Diplodia cococarpa var. malaccensis 
on husk of coconut; Diplodia zeae on Zea mays from Argentina; Fusarium monili- 
forme on Zea mays from Argentina; Gloeosporium sp. on seed head of Pandanus sp. 
from Bermuda; Glomerella cingulata on Arenga sp. from Leeward Islands; Lepto- 
sphaeria iwamotoi on hulls of Oryza sativa from Japan; Leptothyrium sp. on Acer sp. 
from Japan; Nematospora sp. on Pistacia vera from Italy: Pestalozzia sp. on Podo- 
earpus macrophylla from Japan; Phaeoseptoria oryzae on hulls of Oryza sativa from 
Puerto Rico; Phoma sp. on Fraxinus sp. from Germany; Phomopsis cocoes on 
husk of coconut from St. Lucia; Phomopsis sp. on Arenga sp. from Leeward 
Islands; Phomopsis sp. on seed head of Pandanus sp. from Bermuda; Phyllosticta 
sp. on hulls of Oryza sativa from India; Rhizopus sp. on Pistacia vera from Italy; 
Scleroiium oryzae on rice from India (sclerotia on rice grains were not spherical 
as they are in the stems) ; Sclerotium sp. on Castanea mollissima from Japan; 
Sclerotium sp. on Euonymus yedoensis from England; Tilletia horrida on Oryza 
sativa from Netherlands East Indies; Tilletia sp. on Triticum aestivum from Ar- 
gentina; Ustilago bromivora on Bromus catharticus from Argentina; and Verticil- 
lium sp. on hulls of Oryza sativa from Japan. 
Other interceptions of fungi were of special interest because seldom found on 
imported plant material, or because on new hosts or from new countries of origin 
so far as our interception files were concerned. Among these interesting intercep- 
tions were Albugo bliti on Amaranthus from Cuba; Botryosphaeria ribis on Chryso- 
phyllum from Jamaica; Cercospora musae on Musa from Guatemala, Honduras, 
Trinidad, and Venezuela; Clithris quercina on Quercus from Germany; Colletotri- 
chum orchidearum on several genera of orchids from Australia, British Honduras,
