^ Spores coloured; pileus yellow, becoming
moist; stem bollow, confluent
with tbe bymenopbore ; gills becoming
moist, but not deliquescent, at
length losing tbeir colour and becoming
powdery.
Hab. Dung or rank earth near to
towns. (Fig 40.)
A very natural but small genns, intermediate
between Agaricus and Coprinus on
one side, and Coprinus and Cortinarius on the
other ; it resembles Coprinus in its mode of
growth, and ephemeral existence. The species
have no known use.— W.G. S.

Gen. 4 . CO B T IN A B IU S , Fr. Epicr. p. 255.
Spores rusty-ochre, resembling in colour peroxide of iron ;
veil universal, of a different texture to the pileus, and consisting
of arachnoid threads ; a similar veil is found in Agaricus, but it
is tbere either partial, or continuous witb tbe cuticle of pileus;
stem confluent witb the hymenophore ; gills adnate, membranaceous,
persistent, cinnamon-coloured and powdery; trama
floccose.
H a b . Woods and fields.
This genus, ihe most natural amongst the Agaricini, is readily distinguished
by its peculiar habit, but is badly defined by artificial characters ;
the spccii'S are variable in size and changeable in colour; when old they
present a difierent appearance to their young state, and are very different
when dry to when fresh.— W. G. S.
