C. bacillaris var. clavata, Dél. hb. gives K+, which proves that 
it must be united with macilenta. In Fries (L. Suec. 52) the 
specimens of macilenta and bacillaris are intermingled, but the 
ticket bears the name ‘ C. macilenta.’? There exists also a state 
of macilenta with granulated cortex and with the reaction (K +) 
analogous to Mdérkeana.” C. albicans varr. carcata and pseudo- 
cornuta of Délise have K+. 
36. C. rigida, Tayl. (in Lich. Antarct. 119; Nyl. Syn. 1. 
224 n.). 
Of this antarctic species I have seen no specimen. Dr. Ny- 
lander (in litt.) says it belongs to the series K+, and is near to 
C. digitata. 
meek Merythrocarpe (K—). 
37. C. sanguinea, Flk. Of this I only possess a small fertile 
specimen from Dr. J. D. Hooker, without locality. 
Var. anemica, Nyl. (Syn.i. 219). This, Dr. Nylander informs 
me (i Uitt.), has the reaction K—. 
38. C. insignis, Nyl. This, Dr. Nylander says, has K—. 
39. C. cornucopioides, Fr. (Ki. Bot. t. 2051) = Richardson, 80, 
31, 32, 33, 47, 48, 49; Scher. 50,51; Heppe, 5388; Fellm.

My herbarium contains also specimens of this, in its various 
modifications and states, from Untersontheim (Kemler), Upsal 
(Dr. T. M. Fries), Labrador (Breutel), Australasia (Dr. J. D. 
Hooker), Subat and Lheris (Dr. Philippe), Leicestershire and 
Aberdovey, North Wales (Rev. A. Bloxam), Yorkshire (Mr. G. 
Dixon), Basingstoke, Kent (Mr.R.S. Hill), Barmouth and Cader 
Idris, North Wales, Wrekin, Caradoc, Long Mynd, Stiperstones 
Hills, Shropshire. 
40. C. bellidiflora, Scher. (KE. Bot. t. 1894) = T. M. Fries, 
L. Scand. 12; Massal. 173; Anzi, C.C. 16; Scher. L. H..39, 
40, 41, 42; Fellm. 46. 
Of this my herbarium contains specimens also from Savoy 
(Dr. W. Nylander), Newfoundland (Sir W. J. Hooker), Tatra, 
Hungary (Dr. Harslingsky), Grimsel (Scherer), Ben Lomond, 
Scotland, 1823 ft. (Sir W. J. Hooker). 
Var. Hookeri, Ny]. (Syn. i. 221) =Spruce, Amaz. 36, 38. 
I incline to think that this and the following, deformis, may 
be united with cornucopioides, as being states only of the same plant 
under different development resulting from locality, situation, 
and humidity. ‘
