LICHBNES. 9 



ACAROSPORA CHLOROPHANA. 



Acarospora chlorophuna (Wnbg.) Mass. Th. Fries, Lieh. Scand., p. 20*. 



Localities. "From one of islets hi 'old ice,' middle of strait (McMurdo). 

 Collected by Dr. Wilson, December 10th (circa), 1903," on felspar porphyry. Granite 

 Harbour, McMurdo Bay, January 20th, 1902, on basic scoriaceous lava. 



Notes. This is an arctic and alpine plant not previously recorded from the 

 Antarctic. 



ENDOCARPON. 



Endocarpon sp. 



Locality. Granite Harbour, McMurdo Bay, January 20th. 1902, on felspar 

 porphyry. 



Notes. A small fragment only of some species of Endocarpon was found on the 

 same stone as the apothecia of Lecideu auriculata. Sections were cut of the few 

 perithecia present, but they were old and contained no spores. Thus it was possible 

 to determine only the generic name. 



With regard to the specimens which were impossible of determination, the 

 following remarks may be made. A bit of dark scoriaceous lava and a bit of dark 

 basic agglomerate from " Cape Royds, alt. 1500 feet on Mount Erebus, January llth, 

 1904, II. T. F.," both had lichens on them. But they were very simple in structure 

 and also sterile, so that I was quite unable to name them. The alcohol-material from 

 the same locality was, as already mentioned, quite useless. 



There was a minute yellow lichen on some small bits of dark .basic scoriaceous 

 lava from " Winter Quarters," January 13th, 1903, which was not determinable. 



Some felspar porphyry from Granite Harbour (?) has on it a lichen with 

 incomplete apothecia. but with soralia here and there. 



Some granite from Granite Harbour had on it a species of Lffidi'ii (spores 

 'OOG-'007 by '004-' 005 mm.), which was in too incomplete a condition to name. 



From Winter Harbour (December 15th, 1903), we have a quantity of moss on 

 soil. On the moss are found specimens of Lecan<>r<i i'j>ibri/oii and L. < ,/y/iY'/w//.v, 

 Itiiindiiiii tnrfdi-t'ii, and a yellow species which turns red on the application of potash. 

 It is sterile and may belong to some reduced form of Placodium, but I have not been 

 able to place it satisfactorily. It is not unlike "Arnold exsic. no. I(il5, Physcia 

 cirrhochroa Ach., thallus leprosus." The plant seems to be very common : but I have 

 been unable, even after careful searching, to find any apothecia,
