Tubaria palmiosa, and stagnina Galera sphagnorum and Psilo- 
cybe ud«, and in damp woods under alders Naucoria scolecina 
and conspersa. Many of the smaller fungi grow on or among 
living mosses, the habitat being often attested by the name. 
Thus we have Collybia muscigena , Galera hypnorum, Canlhar- 
ellus muscicola. Among the Discomycetes the genera Barlcea 
and Xeottiella and several species of Humaria are muscicolous- 
These are most often found in the winter months. 
There are other special fungus habitats which can here 
only be briefly referred to. Among these are burnt soil, old 
plaster walls, old sacking, linen, and other textile fabrics, and 
all kinds of domestic refuse.

BOTANY 
Re-discovery of Carex Pseudo-cyperus in the East 
Riding. — In the middle of August Mr. J. Cox, of Beverley, 
and some friends paid a visit to the site of Meaux Abbey, of 
which scarcely a vestige now remains. Part of the moat and 
ponds — probably fishponds — belonging to the powerful re- 
religious Order who lived there in mediaeval times, were 
easily traced, and in the latter, and also in ditches adjoining, 
this most interesting Carex was growing in great profusion. 
After a search extending over many years by local botanists, 
the old Teesdalian record in ‘ Beverlac’ of this plant in humble 
Pit, near Beverley, has been confirmed. Its present habitat 
is not a long distance from the above-mentioned pit. which 
had been searched many times in vain. : — J. j. Marshall,.

GEOLOGY. 
Millstones in Yorkshire. — Two Millstones have been 
removed into Cannon Hall Pleasure-grounds from the site of 
an old windmill in the Parish. A fragment I sent to Jermyn 
street i- described as ‘ lava from Xeidermenclig, near Ander- 
nach, in the Eifel. Petrologically the rock has been called 
a leucite-nepheline-tephrite. The stone was used by the 
Romans for Millstones, and has been quarried for the same 
purpose ever since.’ In a Guide to the Rhine, it is mentioned 
that “ a great many of these millstones have been found among 
the Roman ruins in England.” I should be glad to know 
if any have been found in our Yorkshire ‘ Roman ruins,’ and 
whether this is a kind of millstone generally or frequently 
found at old Mills. — Charles F. Pratt. 
[Hand millstones of Roman date, made from Andernach 
phonolite are not at all uncommon on Roman sites, and have 
been recorded for Yorkshire and other northern counties. — E d.].
