Stictina limbata, Smith, var. subflavida, Bab. 



Dr. Nylauder (p. 31, Lich. N.Z. 1889) expresses a doubt 

 of this variety belonging to St. limbata, but, inasmuch as 

 Babington speaks of it as having " cyphellas urceolatas," he 

 inclines, on the other hand, to the belief that subflavida 

 may belong to it. Professor J. Midler, of Geneva, in his 

 " Lichenes Knightiani," page 6, asserts that this variety is 

 nothing else than Stictina intricata, var. thoiiarsii, Del. I 

 cannot accept Dr. Miiller's decision. St. limbata and St. 

 thouarsii are common lichens on the west coast of Scotland, 

 and I am quite familiar with their forms. Babington's 

 variety (of which I possess a specimen) differs in no particu- 

 lar from our Scottish forms, except in its yellow colour above 

 and below. The cyphellte are identical in both as to their 

 irregular outline, although the New Zealand specimen has 

 cyphellas somewhat more farinose at the fundus than the 

 Scottish form. 



I possess another specimen from Mr. F. M. Bailey, of 

 Brisbane, who gathered it somewhere in his neighbourhood. 

 In this the cyphellae are small and more farinose, and present, 

 accordingly, more the appearance of pseudocyphellse titan 

 otherwise, wdiile the whole under-surface is of a beautiful 

 yellow colour as well as the tomentum. This I shall mean- 

 while name Stictina siibcrocea. Both the lichens are barren ; 

 indeed, I am not aware that fruit has ever been found on St. 

 limbata, or on any of its forms. 



I have also from Mr. Bailey three or four specimens of 

 another Stictina, all of which have the granulato-isidiose mar- 

 gin to the thallus so characteristic of Stictina qucrcizans, Ach. 

 The thallus, in all, may be said to be much paler than is usual 

 in St. qucrcizans — viz., "pallidus, pallide lutescens, pallide 

 rufescens, rarius pallide fuscescens " — while its breadth is not 

 more than from 2 in. to 4 in. Beneath the colour may be 

 said to be ochraceous, with a darker tomentum, especially 

 towards the centre. The other characteristics are tliose of 

 St. qucrcizans. Unfortunately, all the specimens are barren. 

 One peculiarity, almost unique, the specimens possess in 

 common — viz., the medulla is pale m the upper half and
