Detonia miniata Rehm; Dodge, Trans. Wise. Acad. 17: 1037. 1914. 



Apothecia gregarious or crowded, at first globose, expanding 

 and becoming subdiscoid, externally pale-orange with a whitish 

 fringe-like border, reaching a diameter of 3-5 mm., but often 

 not exceeding 1 mm.; hymenium becoming plane or a little 

 concave, bright reddish-orange; excipulum composed of a palisade 

 of parallel or rather loosely interwoven, closely septate, and 

 strongly swollen mycelium, the loose ends of which project 

 above, giving rise to the whitish border, the palisade mycelial 

 threads clavate, reaching a diameter of 10-12 jx, often delicately 

 roughened; asci cylindric or subcylindric above, reaching a 

 length of 350 ji and a diameter of 20-26 n, tapering below into 

 a pedicel 7-8 ji in diameter; spores 1-seriate, at first smooth, 

 hyaline, containing one oil-drop which nearly fills the spores, 

 finally becoming sculptured and reaching a diameter of 18-22 ix 

 including sculpturing; spore-sculpturing taking the form of 

 reticulations, the meshes of the reticulations ranging from 2-4 

 or rarely 5-6 ^i in diameter, 3-6-sided, often giving rise to almost 

 perfect hexagonal figures, the ridges of the reticulations less than 

 1 n thick and shallow as indicated by the projections about the 

 periphery of the spore; paraphyses stout, about 5 or 6 /i in 

 diameter below, enlarged above and reaching a diameter of 9 ^ 

 at their apices, filled with minute orange granules. 



On damp soil, usually among mosses. 



Type locality: Brest, France. 



Distribution: New York to Colorado and Bermuda; also 

 in Europe and Australia.

A well-known, widely distributed and rather commonly 

 collected species, small but rather conspicuous by reason of its 

 bright color. It was commonly collected in Bermuda during 

 our recent expedition there.
