Several modern authors (Zopf, Hesse, Sandstede) have followed Acha- 

 Rius in considering the nuiricata as a proper species, but on chemical reasons. 

 They have designated it by the name ^stupped' Flot. (1849 1, but Acha- 

 Rius's name is older: Prodromus (1798) p. 214. 



A fistulöse thallus is generally attributed to the whole subgenus Conii- 

 cularia. According to Sandstede var. nutricata (his stttppea) has an arach- 

 noid medulla, the acitlcata a fistulöse thallus. This usually holds good but 

 not always. In some cases there are some very few hyphae at the centre, 

 leaving it doubtful whether the thallus is really fistulöse or the medulla 

 arachnoid. 



The difference between 'Coniicitlaria uniricatd and 'Coniiciilaria acit- 

 lcata Acharius' was set forth by Acharius with wonted mastery in 

 Methodus Lichenum p. 303. His Coniiciilaria aculcata is e\'idently quite 

 identical with var. caii/pcstris Schaer. 



'Coniiciilaria nutricata' ^Corniciilaria acitleota' 



Rami teretes, axillis \i.\ compressi. Rami ad axillas plano-compressi, sub- 



lacunosi. 

 Rami apice bifurcato-spinulosi. Rami nudi & tantum in extremis 



apicibus' denticulati plurimi breves 

 interdum quasi penicillati. 

 Rami fragillissimi. Rami nee ita fragiles ut in C.iuitricata. 



var. nutricata is also darker. — An enveloppe containing var. nutricata 

 will regularly contain fragments of its fragile thallus, this is not the case 

 with var. cainpcstris. 



Cetraria tcniiissinta var. canipcstris is one of the most common and 

 one of the most widespread lichens in Norway, distributed all over the 

 countr}' and ascending from the level of the sea to above the tree line, 

 var. nutricata is supposed to be less common though in places plentiful.
