Discomycete found on Medlar Fruits. H. Wormald. 293 
to twigs of a Medlar tree in the College grounds but no infection 
of the leaves occurred. 
The direct connection between this discomycete and the 
Monilia with disjunctors found on the leaves was therefore not 
traced, although the fact, noted above, that a fungus, showing 
the same habit when grown in plate cultures as that isolated 
from the leaves, was isolated from the mummies, is suggestive 
that the two forms are stages in the life cycle of the same 
fungus. It appears probable therefore that the discomycete is 
the Sclerotinia Mespili of Schellenberg. 
SUMMARY. 
Mummied Medlar fruits collected from the ground in spring 
and placed on soil in a pot in the open gave rise to fructifications 
of a discomycete in the following spring. 
The fungus differs but slightly from Sclerotinia Mespili as 
described by Schellenberg. 
The differences noticed are: 
(x) the ascospores are distinctly narrower; 
(2) the stalk of the apothecium develops from the apex of 
the primary protuberance, not from the base as mentioned by 
Schellenberg.

Arachnopeziza aurata Fckl. This fungus has been growing on 
the under side of a log of wood in my garden during the last 
five years. In all months of the year I have been able to gather 
material, but growth is most flourishing during the months 
June to October. The specimens of the fungus I have gathered 
hardly justified the specific name aurata until this summer, for 
they have always been nearly colourless, as were also specimens 
I gathered at Porlock Easter and September 1920. Very marked 
characters—the fascicle of elongated ascospores, the much- 
branched paraphyses and the white subiculum—leave no doubt 
as to the identity of the species under consideration. No doubt 
the deeper colour of the apothecia gathered in July may be 
correlated with the brilliant summer weather, the log having 
received more light in its rather shady quarters this year (1921). 
Owing to the presence of a subiculum it was possible to make 
out the early stages in the development of the apothecia which 
to some extent agree with similar stages figured for Evemascus 
albus Eidam.
