in the wood above Porlock Weir. The dark purplish-brown 
iridescent sporangia are seated on stout yellowish stalks and 
are very similar in appearance to the specimens obtained by 
M. Meylan in the Jura Mountains. This is the first British 
record of D. cerifera; it has hitherto only been found in Norway, 
Switzerland and Japan. 
THE LICHENS OF MINEHEAD DISTRICT. 
By H. H. Knight, M.A. 
For the first time since the Mycological Society has included 
Lichens in its program the autumn foray was held in a district 
where these plants were plentiful. A further interest in Lichens 
was given by Mr Paulson’s excellent account of “The Sporu- 
lating Gonidia of Evernia prunasirt.”’ . 
Horner Wood was particularly rich in arboreal species. This 
is an old wood, and not like a modern plantation where the 
trees are too closely packed to admit light for Lichens growing 
on their trunks. The well known Lobaria pulmonaria was 
abundant, also Nephromium lusitanicum and three species of 
Sticta. Other conspicuous plants were Synechoblastus nigrescens, 
Leptogium Burgessit, and species of Pannaria and Parmeliella. 
Thelotrema lepadinum was plentiful on many of the hollies. 
The woods at Selworthy and Porlock were less prolific, and 
more attention was given to the saxicolous species, which were 
found wherever rocks were exposed. In the wood at Dunster 
Thelotrema was again found on hollies; here too were Entero- 
grapha crassa and Phaeographis dendritica which were not seen 
at Horner. 
At Minehead the shingle above high tide level, and rocks on 
the North Hill including Greenaleigh Point were examined. The 
rocks in the district were mostly Devonian sandstone, the 
calcareous species in the list being found on mortared walls. 
For assistance in naming the Lichens in this list I am in- 
debted to Dr Watson of Taunton and to Mr Paulson.
