 fig. 148j, and later Saccardo (Syll. IV, 757) assigned the generie 

 name TriimiKitostroiiKi to a similar fungus. 



The speeies, described and represented by llie former, he called 

 TrlmtiKitostroiiKi Salicls, after its host. Now it deserves notice that 

 Saccardo foimd a fungus on I'ose hips an<l lirst calle(l it I'lrospor/iini 

 fructlcold (Fungi Jtalici, j)l. 40), which he later transplaced to y'r/iinn(i-

The characlerislies of the three repeatedly mentioned genei-a can 

 now be summarised as follo>\s:

 Stroma not or oidy slightly developed.
