SESSION MYCOLOGIQUE OF PARIS.

borne on bis sbonlder. It is noteworthy that in these excursions 
the party keeps very much together, and whenever anything rare 
or interesting is found a whistle or a “ voila ” brings tliem all 
together, the specimen is examined by all before it is consigned to 
the vasculum, and whenever it is divisible it is divided between those 
most interested in that particular group to which it belongs. The 
vivacious and energetic Dr. Cornu, always on the spot whenever 
required, gave such explanations as the less experienced might 
desire, or Fries’ Epicrisis was brought out and consulted under a 
tree, doubtful points cleared up on the spot, and, if new or rare, 
fresh specimens sought after at once. Paris was not reached again 
until 10 p.m., and hence no evening meeting could be held. 
Wednesday, October 24. — The proposed excursion for this day 
was abandoned, and, instead thereof, at one o’clock a party, which 
had been organised for the purpose, was conducted by M. Cornu 
through the National Museum and Herbarium at the Jardin des 
Plantes. In the evening at half-past eight, another meeting was 
held at the rooms of the Society, when some short communica- 
tions were read. One of these described a species of Coprinus 
which was developed on a surgical bandage. Mr. T. Howse read 
a paper on the fungi in the neighbourhood of London, which was 
followed by a general conversation on the fungi of London as com- 
pared with those of Paris ; on the fungi of the markets in both 
countries, and on parasitism of Agarics, such as Nyctalis and 
Agaricus Loveiaaus. Dr. Cornu reported the species found at the 
excursion of the previous day. 
Thursday, October 25. — The excursion was arranged for Mont- 
morency, only a few miles distance, and consequently did not 
necessitate an arrival at the station before ten o’clock. Unfortu- 
nately, this was a thoroughly seasonable day, raining and pouring 
alternately, and all operations were conducted under umbrellas, 
including scratching for Truffles, for this was the “ scratch day.” 
Notwithstanding all these little inconveniences, five species of 
Elapliomyces were found, some of them in considerable number, 
and this was no small achievement when it is remembered that they 
are subterranean, and give no certain indication of their presence 
on the surface, but must be scratched for on “ all fours.” A most 
extraordinary crop of Peziza hadia was found in one place where 
hundreds of specimens, some of them 3 or 4 inches in diameter, 
extended in a scattered manner over about half an acre. In 
another spot the bird’s-nest fungus. Cyathus striatus, was in extra- 
ordinary profusion, in some cases growing in dense masses 6 to 9 
inches in diameter, and prevailing over the whole “ clearing ” of 
some acres in extent. In the evening, at half-past 8, the results 
of the day were announced, and Dr. Cornu explained the structure 
and progress of the new Vine disease, of which specimens were 
exhibited. A report by M. de Seynes on the Hereford meeting 
was also read.
