Geaster arenarius Lloyd:

Lloyd, C.G. 1902. The Geastrae. Mycological Writings 7: 28.

Exoperidium subhygroscopic, cut to five to ten segments; drying usually with segments incurved. Mycelial layer closely adnate with adhering sand. (*) Fleshy layer closely adnate, light color, not rimose. Inner peridium subglobose, with a very short but distinct pedicel in some specimens, in others appearing sessile. Mouth even, conical, acute, definite and usually darker colored than remainder of inner peridium. Columella indistinct. Spores globose, rough, 3-4 mc.
     This little plant which I collected Feb. 1895, in the sand at Jupiter, Florida, I have never succeeded in getting named. My correspondents have suggested "G. saccatus" and "G. floriformis," but I am sure it is neither of these. It is very close to minimus, differing in its shorter pedicel and more hygroscopic exoperidium. It is still closer to Smithii, excepting its mouth.

Specimens in our Collection.

Florida, H. C. Culbertson, C. G. Lloyd, (both from the sand at Jupiter, Florida.)

(*) One specimen alone we have with the mycelial layer peeled away except at the tips, showing its relation to the fornicate section.
