Forming smali pulvinate orange-oohre spongy masses, which, while there

On leaves of box. Winter.
Forming a dense white coating over the leaves, mixed with PenidlUum
roseum, Link of which it appears to be the mature condition. The sporangia
are small and very delicate, so as to be made out with difficulty. In habit
very much like the Pénicillium, but without any roseate tint.

So small as to be scarcely perceptible to the naked eye, forming a velvety
stratum, saturated with the juice of the matrix; sporangia at first white

On sticks in woods.
Scarcely visible to the naked eye ; stem a little flexuous above, ending in
a clavate swelling, beyond which is the globose columella, from the base of
which IS deflected all round over the apex of the stem a delicate frill which
at first formed a portion of the pendulum, and by its rupture leaves a large
circular aperture at its base. Sporangium quite smooth, of two membranes
often separated, sometimes in close contact ; sporidia elliptic, filling the
cavity between the columella and the inner membrane.—AT./ . B.
