Alas see. — A Monograph of 
‘ The inner peridium (endoperidium) is slightly constricted, 
and then swollen at the base, without any groove round the 
top of the peduncle, into which it passes gradually.’ (Berk, in 
Engl. Flora.) 
Geaster fornicatus, Fr. (Fig. 42). Exoperidium split into 
4-5 subequal acute segments, the two layers separating, ex- 
terior cup-shaped, remaining attached to the ground, the inner 
becoming arched and attached to the outer by the tips of the 
segments ; endoperidium shortly pedicellate, obpyriform, peri- 
stome conical, ciliato-sulcate ; spores in the mass dark brown 
with tinge of purple, globose, warted, 3-5 p, ; columella slender, 
olavate, threads of capillitium fusiform, 5-7 \x at thickest part.

Very variable in size, but readily distinguished amongst 
British species by the complete separation except at the tips 
of the two layers forming the exoperidium, and the inner layer 
becoming arched. Geaster radio ans , Berk, and Curt., a North
