tomato found lying on the ground at the Cambridge University

F. A culture of a pycnidial form of fungus from a tomato 
fruit, partly green, partly rotten, found at the same time and 
place as E. 
G. A culture of a pycnidial form of fungus from a half-rotten 
tomato fruit collected at the same place and time as £& and F, 
and only differing from them in that no pycnidia developed 
until it had been kept for some days in the laboratory. This 
culture was found to produce pycnidia and spores very sparingly 
and was later discarded as it was not found possible to obtain 
a single-spore culture from it. In the preliminary examination 
no difference from EF and F could be detected, except that the 
spores were generally slightly smaller. 
H. A culture of a pycnidial form of fungus from a rotten 
tomato (one of seven) collected in a garden at Cambridge,
