Varies a little in the degree of scaliness, but the Gough Island plant is identical 

 with other specimens from Tristan da Cunha. 



Distribution. Tristan da Cunha ; St Helena, and throughout the southern 

 hemisphere. 



Musci. 



For the mosses of Gough Island see Dr Cardot's paper, pp. 57-66 of this volume. 

 The determinations originally published in the Journal of the Linnean Society (loc. cit.)

 continent ; Tristan da Cunha.

MERULIUS AMBIGUUS, Berk. North Amer. Fungi, n. 175; in Grevillea, i. (1872) 69.

Grows on the trunks of Phylica nitida. 



Distribution. North America. 



Du Petit-Thouars * mentions 4 fungi from Tristan da Cunha, among which is a 

 species of Merulius which, from his imperfect description, might quite well be this 

 species. On the other hand, it is quite likely that the American sealers who used to 

 visit Gough Island were responsible for the introduction of this North American 

 species. R. N. R. B.
