SOME OBSERVATIONS ON THE HYMENOMYCETES. 183 
except perhaps with adiposus, which has the colour of a ripe 
pine-apple, but is a rare plant in Scotland. Another of 
these brilliantly coloured Pholiot# is flammans which is not 
uncommon in our woods, growing on fir-stumps. It is of 
very rare occurrence in England, and when the English 
‘mycologists come to this side of the Border, one of our fungi 
they are particularly anxious to see is this fammans. It is 
of a beautiful yellow-tawny colour, not very large; the 
pileus and stem covered with sulphur-yellow, squarrose 
or curly scales; the gills also are at first of a bright 
sulphur-yellow, and the appearance of the whole is very 
striking. 
Mutabilis, again, is a common Pholiota, one of the hygro- 
phanous ones, which change colour as the moisture leaves 
the pileus. When moist, it is of a fine cinnamon colour, - 
and is common, growing on stumps in great cespitose 
masses, the stems scaly and blackish up to the ring, I will 
mention only two more. A beautiful little Pholiota is 
marginatus, which I have found in great abundance among 
fallen pine leaves, growing on the leaves themselves. It is 
one of the neatest of our fungi, a fairy plant with its little 
pileus and ring. There are larger forms of it, some of 
which are not easy to distinguish from wnicolor. Lastly, 
there is a pretty little Pholiota, which I have often found 
on the sod-coping of a stone dyke, growing there among 
Polytrichwm, I mean Pholiota pumilus, of an ochraceous 
colour, with a hemispherical pileus and tiny ring, one of those 
fungi which would be very difficult to identify were it 
not for the presence of the ring. The stem is hardly an 
inch high, and the pileus only three or four lines broad. The 
ring is often indistinct, and then you might easily take 
it for a little nawcoria. 
One might go on in this way for a long time, but it 
would not be for edification. My object, as I have already 
indicated, is to bring out prominently the fact that the study 
of fungi is not nearly so uninteresting as is generally 
supposed, and that the plants themselves are often attractive 
and beautiful iu their own way. And I could, to make 
good my point, have culled examples from other genera of the 
Hymenomycetes besides that of Agaricus. The Cortinarii,
