DEMATIEI. 



On fallen brandies. 



[Low. Carolina.] 



The structure of this plant is at present very imperfectly ascertained. The 

 flocciareofa vinous-brown, and here and there invested with mucilage. 

 The larger sporangiform bodies which adhere to them seem very much to 

 resemble an Ejpicoccum, with its globose, or somewhat obovate scabrous 

 spores.— J/./.^. (Fig. 245.J

Flocci irregular, simple, or sliglitly

Tulasne does not consider this a true genus, 

 but made up of forms, which are conditions of 

 different species of Sjjhceria. New facts are con- 

 tinually strengthening this opinion, but at pre- 

 sent only a few species have been satisfactorily 

 traced ; hence we have retained all, provision- 

 ally. (Fig. 246.;

Tufts effused when growing on the wood, linear, and often forming some- 

 what reticulate, erumpent patches when produced on the bark, rather spongy, 

 coarsely velvety ; threads simple, flexuous, articulated ; articulations irregu- 

 lar, several times as long as broad ; spores terminal, extremely long, linear, 

 multi-articulated, sometimes bent or flexuous j general epispore double, the 

 outer coat thin, the inner extremely thick; endochromes united, about as 

 long as broad, sometimes moniliform, or very irregular, here and there sur- 

 rounded by a broad cavity, which appears granular under the microscope. —
