Recognized by sight: Its certainly minimal in stature, but I don’t think its G. minimum which is not saccate, having a short but noticeable pedicel. Very cool.

The size is right…but

It bothers me a bit that this is all by itself and doesn’t share a common stroma with others. Here’s the original discription. See what you think.

Coilomyces schweinitzii, Berk. & M.A. Curtis:

Berkeley, M.J. and Curtis, M.A. 1853. Journal of the Academy of Natural Sciences Philadelphia 2: 279.


Peridium simplex papyraeeum extus implexo-sericeum (rudimenta peridii externi ;) capillitium e peridio undique radians intus cavum, muris lacunae cribrosis; sporae globosae minutae. Peridia aggregata vel confluentia. Mycelium commune tenue, saltem non crassum suberosum. Genus Broomeiae inter Lycoperdonas analogon.

COILOMYCES SCHWEINITZII, B. and C. Onygena Lycoperdon, Schwein. MSS.

On highly decayed wood : Surinam.

Peridia aggregate or altogether confluent, springing from a common thin, somewhat membranaceous but tough mycelium, ovate rather pointed at the apex, 1-4th or 1-3d of an inch high, white papyraceous, clothed with a matted silky coat. Capillitium containing a regular central subglobose cavity, the walls of which are perforated with numerous pores. Threads radiating from the peridium straight, rather irregular. Spores subglobose minute.

A very curious genus, differing from every thing with which we are acquainted, in its large regular central cavity. It is analogous to Broomeia, but the mycelium does not form a thick corky crust as in that genus, and it is allied to Lycoperdon rather than Geaster.
