THREE FUNGI IMPERFECTI. 
By Jessie S. Bayliss Elliott, D.Sc., and 
Helena C. Chance, M.Sc. 
Three species of Fungi Imperfecti of considerable interest were 
found growing on some dead twigs of Pinus sylvestris picked up 
in the Oxshott Woods, Surrey, January 1919. 
One fungus was somewhat similar to a Cytospora, having its 
sporophores forming a lining layer to the walls of chambered 
pycnidia: it is allied to Cytodiplospora, from which it differs in 
having bi-septate spores when mature: on this account it must 
be placed in a new genus which we propose to call Cytotri- 
plospora. 
CYTOTRIPLOSPORA, gen. nov. 
Stromata erumpentia, pustularia, peridermii laciniis cincta, 
intus pluri-locellata. Sporulae copiosae, allantoideae, hyalinae, 
primo continuae, deinde biseptatae, sporophoris longioribus 
suffultae. 
CYTOTRIPLOSPORA PINI, sp. nov. 
Pycnidia subconferta, breviter parallele et longitudinaliter 
seriata, oblonga, 1-6-locellata, atra, 300-500 w diam., tandem 
apice erumpentia; sporulae allantoideae, hyalinae, continuae, 
deinde 1-2-septatae, 15 x 4:5, sporophoris simplicibus, fili- 
formibus, rectis, acutis, circa 1} quam sporula longioribus suf- 
fultae; sporophorae cum sporulis maturis dilabuntur, et tunc 
spinae vel cilii speciem ostendunt. 
Hab. in ramulis Pini sylvestris, Oxshott Woods, Surrey. 
Pycnidia rather crowded, occurring in irregular lines, some- 
what parallel, following the long axis of the twig, oblong,
