of Jacksonville, Fla., on Carpinus Caroliniana. Mr. Calkins in- 

 forms me tliat he has found this plant but once, and I am of the 

 opinion that it may occur more abundantly in more tropical re- 

 gions. (Lichens of Florida, p. 6, No. 193, Eckfeldt and Calkins.) 



Stigmatidium inscriptum, Nyl. spec. nov. 



Thallus albidus, tenuis, rugulosus, rimulosus; apothecia nigri- 

 cantia gracilia elongata dendroideae, divisa innata ; spora^ 8 n^. 

 incolores, oblongae, 3 septatae, long. 0,01 1- 14, crass. 0,004-5 mm. ; 

 epithecium incolor, hypothecium fuscum. lodo gelatina hymen- 

 ialis caerulescens, dein fulvescens. 



This remarkable species o{ Stigmatidium, which is most likely 

 also of tropical origin, is, so far as we are aware, the only type of 

 the genus ever occurring within the limits of the United States. 

 The species, so far as known, are commonly found in Southern 

 Europe and Equatorial America. The similarity of the species is 

 also quite marked, and this plant is very closely allied to 5. 

 ■venosa, Sm. and S. elegans, Esch. Our plants occur commonly 

 at Jacksonville on Carpinus Caroliniana and Querciis virens
