On rotten stumps, pales, &c. Spring — Autumn. Common. — Varying 

 much in colour and size, and the hue of the sporidia. The surface is 

 rough with dot-like scurfy warts, and changes colour sooner than the 

 pulpy mass within, which is often of the finest scarlet, and oozes out 

 in large drops if the peridium is injured. Lycogala fidiginosa, Johnst. ! 

 Fl. Berw. 2. p. 189, agrees in colour with Lye. plambeum, Fr., but it 

 appears not to be furnished with a regular mouth, and is probably only 

 a form of the present species.

Peridium indeterminate, simple, naked, fngacious. Flocci 

 branched and shrubby, reticulated. — Name, reticulum, a little 

 net. 



1. R. maxima, Fr. {large Reticularia) ; hypothallus effused, 

 peridium very thin tuberculate white then purple-black, flocci 

 adnate at the base fasciculate, sporidia black-purple. Er. Syst.

 'iSowerby. — I am not sure whether the plant of Sowerby before me is 

 the same with that of Fries, as the specimens are not perfect, but I 

 Judge from the colour of the sporidia, effused hypothallus, and tuber- 

 culate surface. Sowerby found it in great abundance, and a quantity of 

 the sporidia subjected to considerable heat by Dr. Wollaston formed 

 a phosphoric glass. 



2. R. dtra, A. & S. (black Reticularia) ; subpulvinate, perl- 

 iiium very thin subreticulate, flocci arising from the base divari- 

 cated dendroid black as well as the mature sporidia. Alb. 4^

 from the base erect branched umber as well as the sporidia.
