Tyrol. 



There is some difficulty in ascertaining the exact meaning 

 of the colour of the sporangium as given by Rostafinski, who 

 calls it " kawowo-mleczne." It is translated in Saccardo's 

 Sylloge as " sanguineo-lacteis." 



Chondrioderma vaccinum, Rost.

 thin, evanescent ; columella ahsent ; threads of capillitium 

 hyaline, delicate; spores pale brownish-violet, 10 — 11 ij. diameter, 

 minutely wavted.

Externally bearing a close resemblance to Chondrioderma 

 testaeeum, but easily recognized by the absence of a columella; 

 Chondrioderma sMateritiwm is separated from the present species 

 in having the upper surface of the sporangium broadly um- 

 bilicate, and in the presence of a columella. 



Chondrioderma simplex, Schroeter. 



Sporangia sphaeroid, slightly flattened, scattered, simple, 

 rigid, fragile, bright chestnut ; columella ahsent ; tubes of capil- 

 litium radiating, repeatedly dichotomous, violet; sjyores smooth, 

 bright violet, 7 — 9 fx diameter.
