forming very irregular stalactitic or tuberculose crust-like 

 patches. White, soft, and fleshy when growing. Smell 

 none.

 incrustans, TuL, Ann. Sci. Nat. (1872), t. x. f. 5-10. 



Soppittiella caesia. Mass. 



Effused, thin, soft, bright grey, determinate ; inseparable ;

Thelephora caesia, Persoon, Obs. Myo. i. t. 3, f. 6. On 

 wood, moss, &c., on the ground. Forming thin, determinate 

 patches 1-4 or 5 in. across, soft and almost subgelatinous 

 when growing, hymenium not cracked when dry; hyphae 

 brownish. Superficially resembling a thin soft Gorticium, 

 but with the pale vinous or brownish echinulate spores of
