266 THE BOTANY OF GOUGH ISLAND. 
Du Petit-Thouars* mentions four fungi from Tristan da Cunha, 
among which is a species of Merulius which, from his im perfect 
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.] 
The Lichens of Gough Island. 
By Orro V. DARBISHIRE. 
The following is an enumeration of the seven species of Lichens 
brought from Gough Island by the Scottish National Antarctic 
Expedition, and collected there by Mr. R. N. Rudmose Brown 
in April 1904. Of the seven species five are already known as 
being arctic and alpine plants. 
CLADONIA squamosa, Hoffm. Deutsche Fl. ii. 152. 
Cosmopolitan, but not arctic. This plant was found in small 
quantities. 
PanMELIA CETRATA, Ach. Syn. Meth. Lich. 198. 
This species was found growing on branches of P/yliea. It 
is most commonly met with in more temperate parts of the 
world, but I do not doubt that the specimens before me, though 
sterile, do belong to this species. 
PARMELIA SPHEROSPORELLA, Muell. Arg. in Flora, Ixxiv. (1891) 
318. 
This specimen is small and incomplete, but both in internal 
structure and external appearance it corresponds to the original 
specimen and description of J. Müller Argoviensis. He records 
its occurrence in the hills of Oregon. 
UsNEA BARBATA, Fries, Sched. Crit. Lich. Suec. 31. 
A number of good healthy specimens, all sterile, were brought 
back from Gough Island. No attempt has been made to separate 
out the varieties of this species. Itis found in every part of the 
world, being common also as an arctic plant. 
RAMALINA SCOPULORUM, Ach. Lich. Univ. 604. 
Arctic, in Europe, Asia, and America. Gathered from rocks, 
and in full fruit.
