Mcissee, — A Monograph of 
thick, stem-like base, smoky brown above, becoming whitish 
below, minutely areolato-furfuraceous, dehiscing by a small 
irregular aperture. Capillitium continuous with the well- 
developed whitish cellular sterile base, threads variable in

This species has hitherto been confounded with B. pusillnm, 
from which it is readily distinguished by the presence of a 
well-developed, convex, sterile base, and absence of the long, 
slender, tapering root characteristic of B. pusillum. Gre- 
garious. From J-| in. across. 
GEASTER, Micheli. 
Peridium at first continuous, consisting of three layers, the 
two outermost (exoperidium) usually continuous, splitting from 
the apex in a stellate manner; inner layer (endoperidium) 
sessile or pedicellate, furnished at the apex with one, rarely 
more orifices; columella prominent or rudimentary; capillitium 
dense ; spores coloured.

‘ In one species (G. coliformis ) the inner peridium (endo- 
peridium) is supported by several stems, and the orifices are 
numerous. This has led to its removal by some mycologists 
from this to a new genus. We prefer to retain it as a sub- 
genus. In the rest the orifice and support is single.’
