Tuck. 38. 
This I possess also from Mount Spliigen and Engstlen Alp

Kotzebue Sound (Dr. J. D. Hooker), Subat (Dr. Philippe), 
Salzburg (Dr. Schwarz), Untersontherm (Kemler), Leicester- 
shire (Rev. A. Bloxam). 
Is not this also a state of cornucopioides ?

This also I have from Salzburg (Dr. Schwarz), Austria (Dr. 
Holzinger), Belgium (Abbé Coémans), Leicestershire (Rev. A.

This has been hitherto, by external aspect, confused with C. 
macilenta (K+), but is separated by different reaction (K—), 
and is only a var. of Flérkeana analogous as pleurota is to cornu- 
copivides. For various remarks connected with it, see under C. 
macilenta, antea. 
The followimg remarks are from Dr. Nylander’s annotations 
on the types of Cenomyce of Délise, in his herbarium at the 
Jardin des Plantes, Paris, which he has liberally communicated 
(in litt.) to me :—C. digitata var. mucronata, Del. hb., has K—, 
and C. albicans, Dél., has K—, and therefore are referable to 
bacillaris. The C. bacillaris, Dél., and his varicties styracella, 
macrocarpa, densiflora, paleata, coronata, according to the speci- 
mens in herb. Délise, have K—, and belong to C. Florkeana 
* bacillaris. 
Var. ostreata, Nyl. (Syn. 1. p. 225)=Nyl. L. P. 108. 
Of this Dr. Nylander writes (in litt.), “Ob podetia Cladonie 
bacillaris immixta squamis parum evolutis Lecidee ostreate ste- 
rilis, olim credidi Lichenem in L. P. 108 datum varietatem 
sistere Cladoni@ illius squamis recedentibus. Quod corrigendum 
est, et varietas nomine ‘ ostreata’ delenda.”
