manner, wall thick, brown with a tinge of purple, famished 

 with large, scattered, innate, yellow patches of lime ; columella

Did.ymium reticulatum, B. and Br., in Herb. Berk. 



On bark and mosses. Ceylon. 



Distinguished from Lepidoderma Chailletii by the absence 

 of a columella, and from L. Carestianum by the smooth spores 

 and yellow patches of lime on the wall of the sporangium. 



Lepidoderma fulvum, Mass. (n. sp.) (figs. 39, 40). 



Sporangia stipitate, hemispherical, depressed, umbilicate 

 beneath, fulvous, with scattered, large, superficial white or yellowish 

 scales ; stem stout, equal, or very slightly attenuated upwards, 

 straight or a little bent, longitudinally rugulose, fulvous, hypo- 

 thallus well developed ; columella large, hemispherical, brownish ; 

 capillitium copious, threads slender, branched at acute angles, 

 jlexuous, brownish-violet ; spores globose, smooth, brownish-purple, 

 10 12 // diameter, some few much larger.

 (Type in Herb. Berk., 10,783.) 



In groups of 2 4, springing from a firm, well-developed 

 hypothallus, 2'5 3 mm. high. Differing from Lepidoderma 

 stellatum, the only other stipitate, smooth-spored species, in the 

 coloured columella and stem. The calcareous scales on the 

 pileus very thin, glistening, not so regular and distant as in 

 L. fulvum. 



B. Spores warted. 



Lepidoderma tigrinum, Host. (figs. 41 43). 



Sporangia hemispherical, depressed, stipitate, umbilicate 

 beneath, blacldsh-brown, and furnished with rather distant, large 

 yelloivish scales ; stem erect, thick and equal, or slightly attenu-
