1 46 CR YPTOGAMI A FUNGI. 



79. PODISOMA. 



1. P. clavariaformis, gregarious, tooth-like, cylindrical or some- 

 what compressed, orange-yellow, smooth ; granules elliptical, 

 acute at each end. Bot. Gall. ii. 881. Tremella clavariceformis* 

 GREV. Fl. Edin. 427- 



Hab. On the living branches of the juniper, in clusters, 

 studding the affected branch for 2 or 3 inches with 

 fungus-like spines pointing in every direction. Spring. 



Simple, about fths in height, tapered, brownish at the tip, 

 tough when dry, soft when moist. Each fungus is com- 

 posed of an immense number of grains, which are large, 

 bilocular, acute at each end, and often terminated by what 

 seems to be a pellucid hair, but which is probably the ge- 

 latine so drawn out. Sometimes a number of the grains 

 are united together in a moniliform series. 



80. TUBERCULARIA. 



OBS. Tubercularia seems nearly allied to Sclerolium, but in the 

 former, the granules, instead of being diffused through the whole 

 mass, are confined to a layer superimposed on a fleshy base. The 

 species are of a red colour, parasitical on decayed wood, which 

 they spot with wart-like tubercles.

Hab. On decaying sticks, particularly on beech, common 

 in autumn and winter. 



Gregarious, studding the branches for a considerable space 

 with scattered red rather small tubercles, which are soft 

 but not gelatinous when moist, hard when dry. The tu- 

 bercles are subglobular, raised on a very short thick base 

 concealed by the ruptured bark, and internally of a red- 

 dish-brown colour. 



2. T. confluens, gregarious, becoming confluent, depressed,
