318 T’?Abbé KE. Coémans on the Cladoniz 
My learned friend Dr. Nylander regards C. crispata as a 
probable hybrid of C. furcata and gracilis. Is it not, rather, an 
intermediate product of C. furcata and squamosa? The herba- 
rium of Florke at Rostock possesses many mixed forms between 
these two species. 
28. Cladonia sparassa, (Ach.) Syn. p. 278 et hb. ejusd. 
This species is more generally known under the name of 
Cladonia squamosa, Hffm. 
The Acharian herbarium contains only the most common 
forms of this species, which probably explains why Acharius, 
who was fond of multiplying forms, is here so sparing of his 
varieties. 
Amongst his specimens are two beautiful specimens of C. de- 
corticata, Fr. 
29. Cladonia cariosa, (Ach.) Syn. p. 278 et hb. ejusd, ~ 
This species is represented in the Acharian herbarium by a 
dozen specimens, from different localities, and all perfectly 
typical. 
There is a young and undeveloped form of C. cariosa, which 
is ordinarily given in Exsiccata under the name of C. cariosa, 
var. symphycarpa (Ach.). This is not found in this place in the 
Acharian collection, because he regarded it as belonging to the 
following species. 
Some authors still unite C. cariosa with C. pyxidata. Iam, 
however, fully convinced that it forms a good and excellent 
species. 
30. Cladonia symphycarpa, (Ach.) Syn. p. 274 et hb. ejusd. 
Under this name I found in the Acharian herbarium— 
(1) Some young examples of C. cariosa from Sweden. This 
is the form which Scherer, Desmaziéres, Rabenhorst, Hepp, and 
Massalongo have published under the name of C. cariosa, var. 
symphycarpa (Ach.). It does not differ sufficiently from the 
type to constitute a variety. 
(2) A fructiferous specimen, with small imbricated leaflets, of 
C. alcicornis, var. firma, Nyl., from Switzerland. 
(3) A small specimen of the same plant, gathered in ancient 
Lusatia (environs of Gorlitz), and altogether similar to No. 13 
of my ‘ Cladoniz Belgice.’ 
(4) Some fragments of a short condensate form of C.macilenta 
from North America. 
(5) Lastly, a specimen of C. turgida, reduced to a dense and 
microphylline thallus, as in my ‘ Cladonie Belgice,’ No. 19. 
Amidst this diversity, it is naturally very difficult to say what
