NEW SPECIES AND NEW, UNUSUAL. OR OTHERWISE INTERESTING RECORDS 
A number of interceptions were of particular interest because they were unlike 
described species or unlike species known to occur on the host or because the 
record was unusual for some reason. Among these interceptions were the fol- 
lowing: Ascochyta sp. associated with Cercospora petroselini Sacc. on parsley from 
Morocco and a later interception of what may be the same species on parsley from 
Germany; citrus canker, Bacterium ciiri (Hasse) Doidge, was intercepted on 
citrus from Ceylon, China, Dutch East Indies, Japan, and Straits Settlements, 
the hosts including lemon for the first time in our interception records; Botrjjtis 
alia M, T. Munn was intercepted from the Tropics for the first time on onions 
from Straits Settlements; Camarosporium sp., no species reported on orchids, was 
found on Oncidium sp. from Honduras; Cephalosporium pammelii var. purpuras- 
cens Buchanan was again intercepted on apples from Japan; a black rot of carrot 
intercepted from Belgium, England, France, and Germany had, in several cases, 
numerous fruiting bodies of a fungus tentatively determined as Ceratostomella 
fimhriaia (E. and H.) EIL; Cercospora sp., probably a new species, was found on 
Tradescantia from Mexico; Cercospora sp., no species found reported on the host, 
was intercepted on Cordia from Mexico; Colletotrichum agaves Cav. on agave from 
Mexico; Colletotrichum sp., near C. lujae Verpl. and Claess. but perhaps a new 
species, was found on orchid from Dominican Republic; Colletotrichum sp., unlike 
species reported on host, was found on Oncidium from Mexico; Coniosporium sp., 
unlike species reported on bamboo, was found on a bamboo stake in plants from 
Canada; Coniothyrium. sp., unlike either species reported on orchids, was inter- 
cepted on Oncidium from Honduras; Didyrnella sp., unlike species reported on rose, 
found on manetti rose stocks from Netherlands; Elsinoe australis Bitancourt and 
Jenkins was intercepted on shipments of lemons from Paraguay; Gloeosporium 
affini Sacc. was intercepted on orchids from Costa Rica and Venezuela; G. oncidii 
Oud. was found on orchids from Costa Rica; an unusual Gloeosporium, not deter- 
minable, was found on peppers from Cuba; Heterosporium aZZu Ellis and Mart, was 
intercepted on onion for the first time, material being from Chile and France; 
Kahatiella sp. was isolated from a rot of apple from Australia; Mollisia sp., no 
species reported on orchids, was found on orchids from Guatemala; a fungus found 
infecting spruce cones from Germany did not fit the description of any named 
species of Myxosporium or Gloeosporium; Ophioholus sp., no species reported on 
orchids, was found on a shipment of Cattleya mossiae from Venezuela; Papulospora 
parasitica (Eid.) Harz was intercepted on tulips from Netherlands; Pestalozzia 
spp., unlike any species reported on orchids, were found on orchids from Guate- 
mala and on Cymhidium from Japan; an undetermined species of Phoma, appar- 
ently new, was found on Hoodia and Raveresia from South Africa; Phomopsis 
spp., unlike species reported on the hosts, w^ere intercepted on orchids from 
Guatemala, on Cymhidium from India, and on pods of Myroxylon from Trinidad; 
Phyllosticta sp. was intercepted on Arachis glabrata from Brazil, no such fungus 
seems to have been reported on Arachis; Phyllosticta sp., unlike any species report- 
ed on rice, was found on rice straw from Ceylon; a rust on bamboo from China was 
determined as Puccinia mitriformis Kusano but did not fit the description; Rhizoc- 
tonia bataticola (Taub.) Butler, formerly listed as Sclerotiurn bataticola Taub., con- 
tinued to be intercepted on melons from Argentina and Chile; undetermined mi- 
nute black sclerotia were found in horseradish root from Germany; undetermined 
minute black sclerotia were plentiful in morning-glory roots from Japan; diseased 
passion fruit from Madeira Islands had fruiting bodies and spores resembling 
those of Septoria fructigena B. and C. but was not definitely determinable; Spha- 
celoma perseae Jenkins was intercepted on avocados from Colombia; Uredo sp., 
apparently an un described species, was intercepted on Oncidium from Mexico; 
IJromyces betae (Pers.) Lev. was intercepted on beet leaves from Chile, indicating 
that this rust occurs in South America ; Uromyces lespedezae-procumbentis (Schw.) 
Curt, was intercepted on leaves in shipments of lespedeza seed from Japan, and 
the fact that the Asiatic and American rusts under this name do not appear to 
infect each other's hosts makes it desirable to prevent entry of the Asiatic form; 
Volutella sp., apparently an undescribed species, was intercepted on sour oranges 
from Japan. 
Unsuccessful efforts were made to isolate an organism from an apparently sterile 
spotting more or less prevalent on Mexican citrus fruits. If the disease spreads 
as alleged by some it may be virus trouble. 
The flowers of plants of Saccharum spontaneum grown from imported seed col- 
lected in Turkestan were found to contain a new species of seed-infesting nema 
(Anguina spermophaga Steiner), which may have been brought in with the seed.
