Dunster by train. There were few of the larger fungi to be seen, 
but Lepiota nympharum, L. haematosperma, L. Friesw and 
Pleurotus corticatus were met with. Kuehneola albida was not 
uncommon and Oidium alphitoides on Beech and Helotium 
moniliferum were collected. Most members walked back to 
Minehead along the coast. 
At the evening meeting a communication was read from 
Professor A. H. R. Buller on the audibility of the “ puffing” in 
the larger Discomycetes. A specimen of Pustularia catinus was 
seen to puff and was held to the ear as one does a shell: a 
distinct sound was heard like that made by steam when escaping 
from a tiny jet. 
A note by Mr St John Marriott on the discharge of the 
peridiolum in Sfhaerobolus stellatus stated that the greatest 
distance to which these had been thrown was twelve inches. 
Mr R. Paulson then gave a paper on “‘ The sporulating gonidia 
of Evernia prunastri*.” 
Mr Ramsbottom exhibited pieces of canvas from different 
war areas showing “diamond spot” caused by Macrosporium 
and Stemphylium which was responsible for so much damage 
to tentage and which is of great economic importance. The 
methods of treatment which had been advocated to prevent 
the trouble were briefly commented on and specimens of treated 
canvas exhibited. 
The meeting ended by votes of thanks to Captain Luttrell 
for permission to explore Dunster and to Mr N. G. Hadden for 
making the arrangements for the excursions; to the Foray 
Secretary, Mr A. A. Pearson, and to the President Mr T. Petch. 
All the members present contributed in some way or other 
in the compilation of the following list of species found during 
the foray. I would express my thanks particularly to Mr 
Carleton Rea for assistance in the field and to Dr J. S. Bayliss 
Elliott, Mr C. H. Grinling, Mr N. G. Hadden, Sir H. Hawley 
and Mr A. A. Pearson for lists of their finds.
