SOME OBSERVATIONS ON PUCCINIA BISTORTA. 
47 
It may also be stated that in every case where the iEcidium was 
observed in spring the Bistort was afterwards attacked with the 
uredo and teleutospores, so that this Puccinia is undoubtedly an 
hetercecious species, and its mode of development is similar to that 
of the well-known Puccinia graminis. 
In some respects the iEcidiospores bear a resemblance to 
Mcidium Bunii , D.C., but at present I cannot convince myself that 
they are identical. 
Fungus Forays. 
The annual foray promoted by the Yorkshire Naturalists’ Union 
was held at Pocklington on September 6th and 7th, and may fairly 
be said, from every point of view, to have been the most successful 
of any foray conducted under the auspices of the Society. More 
mycologists were present than on any previous occasion, and 
realizing that the guests were experts, the old hands felt it ex- 
pedient to say but little and seldom, having in view the reputation 
of the Society, also the commendable ambition to make the York- 
shire foray the centre of attraction for mycologists of the present 
day ; and thus, to some extent at least, take the place of the 
Hereford meetings of bygone days. The advantage of the York- 
shire foray consists in selecting a new locality for the meeting each 
year, and, naturally, everything depends on a suitable place being 
selected, hence it will be well for the Council of the Society to 
listen to the advice of those competent to give an opinion as to the 
place where the forthcoming foray is to be held, and to act on it. 
The official programme announcing the locality and date of the 
foray is sent out only a few days before the event. This notice is 
too short, especially for those who are not members, and an official 
invitation, with date and locality, might with advantage be sent to 
mycologists at least a month in advance, and would be more polite 
than the usual programme, which, for some unexplained and un- 
called-for reason, states that of the two days the one not being the 
fungus foray is most important. As a matter of fact, mycologists 
attend to their own special work on both days, and some of the 
more enthusiastic members assemble for work two or three days 
before the official date. When the above trifling shortcomings are 
rectified — and I am convinced it is the desire of everyone officially 
representing the Union to promote the study of every branch of 
natural science — the prospect of a strong mycological section is 
very favourable, indeed certain. 
To return to the foray, fungi were comparatively scarce, owing 
to the dry season, and not to the locality selected ; this, however, 
is always an advantage, as the specimens are certain to be more 
critically examined than when the numbers to be arranged for the 
“ show ” are so numerous that the whole time available is spent in
