Faligo tatrka, Raciborski, in Heclwigia, 1885, p. 10!); Sacc, 

 SylL, vii., 1, n. 1229. 



On fallen trunks. Hungary. 



Crateriachea, Rost. 



Sporangia irregularly ruptured during dehiscence, lower 

 portion persistent, margin lacerated. Columella central, cylin- 

 drical, containing lime. Threads of the capillitium delicate, 

 combined to form a network, nodes not usually developed, here 

 and there inflated and containing granules of lime, meshes of 

 the network becoming smaller towards the periphery, termin- 

 ating in short arms that are attached to the wall.

 p. 858 ; Cooke, Brit. Myx., p. 20. 



Apparently intermediate in some respects between the Litho- 

 dermcac and the Columcllifcrae, departing from the former in 

 the paucity of lime and the thin tubes of the capillitium, form- 

 ing a network which originates from the elongated columella, 

 but differing from the latter in the tendency to form nodes 

 containing lime not being yet obliterated. Distinct from 

 Gratcrium in the distinct columella and rudimentary nodes of 

 the capillitium. 



Distrib. Germany. Species 1. 



Crateriachea mutabilis, Rost. 



Sporangia cylindrical, attenuated below, then expanding into 

 a discoid hypothallus, every part reddish-brown ; spores dingy 

 violet, globose, 8—10 ix diameter, strongly loartcd.
