17—GEASTER RADICANS 
Exoperidium typically fornicate, the outer layer separating and 
remaining as cup at the base, not having mycelium except at the base 
where it is strongly developed in a 
cluster of root-like fibers. Fibrillose 
layer arched, cut to five (or usually 
four probably) segments. Fleshy layer 
thin, dark reddish, closely adherent. 
Inner peridium subglobose but taper¬ 
ing to the base Mouth indefinite. 
Spores globose, almost smooth, 4 me. 
This plant related to fornicatus, 
is strongly different in the basal my¬ 
celium, and in the cup having lobes. 
It enjoys the unique distinction of 
being the only American species that 
has never been claimed by any one to 
grow in Europe. The only specimens 
we have seen are Rav. exsie. No. 108, 
and in the collection of Division of Veg. 
Pathology of Washington, where it 
was labeled “fornicatus. ” It grew on 
“a cedar login Florida,” but the collec¬ 
tor’s name not preserved. All its re¬ 
corded stations are Southern and we 
believe it does not grow in our North¬

18—GEASTER CORONATUS. 
Exoperidium fornicate, the mycelial layer forming an imperfect 
cup to which the arched segments of the fibrillose layer are loosely 
attached at the tips. The cup is not perfect however, as in the two 
previous species, but the mycelium is so strongly developed that ad¬ 
hering dirt and pine-needles represent an irregular mass rather than a 
definite cup Segments of the arched fibrillose layer usually four, 
sometimes five, deeply cut, but relatively short as compared to the seg¬ 
ments of fornicatus Flesh) 7 layer light colored, partially adherent or 
sometimes entirely peeled off. Inner peridium oblong, tapering to a 
short pedicel at the base and to an acute mouth at the apex, covered 
with minute granular particles. Mouth definite. Spores globose, rough¬ 
ened, 4 me.
