orange-vellow, and K gives on this surface a vellow thin red 

 reaction. 



This Parmelia is certainly closely allied to P. suhtiliacea, 

 Nyl. (Lich. N.Z., 1889, p. 26), but the spores, in five different 

 examples examined, are as given above, while those of P. suh- 

 tiliacea are 0'014-0-017xO-007-0-008 mm., and the " thallus 

 albidus." Krempelhiiber describes ("Novara" Exp., p. 114) 

 a Parmelia under the name P. jelinekii, which is also allied 

 to the present. Its thallus is " ochroleucus," and the sub- 

 medullary stratum is "late aureum " ; but the spores are 

 exactly as given above under P. suhtiliacea, perhaps a little 

 longer. 



I have another small barren specimen, from the Grampian 

 Mountains of Victoria, gathered by Mr. Sullivan, which is re- 

 markable for the peculiar reaction by C on the medulla. 



Parmelia violascens, Strn. 



Similis P. conspersce, var. stenophyllce sed minor, adpressa et 

 thallo saepe isidiato ; medulla alba K flavens C intense violacea 

 vel coloris magentge. Color thalli virescenti-lutescens vel 

 lutescens. 



Parmelia platycarpa, Strn. 



Corticola prope Brisbane {F. M. Bailey). This lichen is 

 described in the " Scottish Naturalist " for April, 1878, and, 

 as stated there, is allied to P. latissima, Fee. Dr. Nylander, 

 in Lich. Granatse, vol. i., p. 24, merely mentions a form of 

 P. latissima — " thallo fiavescenti." Nothing can be founded 

 on .this statement. I am still in ignorance of the shape and 

 size of the spermatia of P. latissima. Those of P. platycarpa 

 are straight, cyhndricai, and about 0-006 x 0-0006 mm. 



Parmelia cyathina, Strn. 



Corticola prope Brisbane {F. M. Bailey). Described in the 

 same number of Scot. Nat. This also, as stated, is closely 

 allied to P. neUgherrensis, Nyl., and more especially to 

 P. suhrugata, Nyl. (Exot. Flechten, p. 320) ; but I can get 

 no information concernmg their spermatia. Those of P. cya- 

 thina are cylindrical, very often curved, and 0-005-0-006 x 

 0-0009-0-0011 mm. 



I have another Parmelia from Queensland, gathered by 

 Mr. F. M. Bailey on Darling Downs, whose characters are 

 almost identical with those of another from Sikhim, Hima- 

 layas, by Dr. George Watt. 



Parmelia confertula, Strn.

 laciniis S£epe imbricatis et margine lobatis et crenatis, subtus
