Chondrioderma floriforme, Host, Mon., p. 184 (excl. syn. 

 Diderma concinnum, B. and Br., added by Rostafinski in Mon. 

 Append.) ; Cooke, Brit. Myx., p. 41 ; Sacc., Syll., n. 1285 (excl. 

 syn. Diderma concinnum, B. and Br.) ; Raunk., p. 84. 



Exsicc. Ellis, N. Amer. Fung., 1121 ; in Fuckel, Fung. 

 Rhen., 2496, the specimen agrees in every respect with the 

 above description except that the spores are almost smooth. 

 Rostafinski describes the spores as having scattered spines, 

 which is translated by Cooke, Myx. Brit., p. 41, as " rarely 

 spinulose," and the description in Saccardo's " Sylloge " is a 

 translation of Cooke's version, hence incorrect.

 States. 



About 2 - 5 mm. high, sporangia polished, wall thick ; super- 

 ficially resembling some stipitate forms of Lepidoderma radiatum 

 before dehiscence, but the latter is distinguished by the stem 

 being much attenuated towards the base.
