Geaster asper is on the plate of the first Geasters figured 
(Miehelius, 1729, pi. 100, f. 2;, where the plant is characteristically 
shown, excepting the pedicel is more slender than normal. The word

“asper” is the first descriptive adjective applied by Miehelius. Fries 
included it in his complex striatus. It has been described as a new 
species in recent times by three authors; as G. campestris by Morgan 
(1887) ; as G. Berkeleyi by Massee (1889) ; and as G. pseudomammo- 
sus by Henning in 1900.

9—GEASTER MORGANII. 
Young plant acute. Exoperidium cut beyond the middle to 
seven to nine acute segments. In herbarium specimens usually saccate 
but sometimes revolute. Mycelial layer closely adherent, compared to 
previous species relatively smooth. (*) Fleshy layer when dry, thin 
closely adherent. Endoperidium globose, sessile. Mouth silicate, in¬ 
definite. Columella globose-clavate. Capillitium thicker than the 
spores. Spores small, globose, 4 me, almost smooth. 
This plant is common around Cincinnati and was referred by 
Morgan to “striatus.” It is a reddish brown plant and differs widety 
from other species with sulcate mouths previously described in its 
(*) As in the previous species the mycelium covers the young plant but is not so strongly 
developed so that the adhering dirt is not so evident on the mature plant.
