This plant in moist shady localities is of a beautiful green colour, 
becoming yellowish when long preserved in herbaria. The apothecia are 
generally numerous, often much crowded and almost confluent, undu- 
late when dry, rarely substipitate, occasionally entirely lecanorine, with 
depressed thalline margin. The spermogones are inclosed in the thalline 
granules in colourless conceptacles; the spermatia slender, somewhat 
thickened at either apex, 0,004 mm. long, scarcely 0,001 mm. thick. 
Though much difference exists as to the place of this species, it is anato- 
mically and chemically a Beomyces, as observed by Nylander, Lapp. Or. 
p. 108. 
Hab. On moist turfy soil, on decayed Sphagna in bogs, and on putrid

local, but plentiful where it occurs, in the hilly tracts of England and North

Tribe IV. PILOPHOREI Nyl. ex Cromb. Grevillea, v. 
(1876) p. 77. 
Thallus formed of rigid, cylindrical, fistulose or internally arach- 
noid and externally granulose podetia, usually also granulose or 
pulveraceous at the base. Apothecia terminal, capituliform, black ; 
paraphyses prolonged directly into the hypothecium; spores 8na, 
ellipsoid, simple, colourless. Spermogones with nearly simple ste- 
rigmata, 
The single genus of which this tribe consists has been arranged by
