HYPOXYLON CEREBRINUM (FIG. 815), FROM J. B. 

 HART, TRINIDAD. We received this fine specimen from Mr. 

 Hart many years ago, but at that time we had not worked at 

 all on the large Pyrenomycetes. We sent it to Ellis, who advised 

 us that it was a new species, and proposed the name Hypoxylon 

 herculeum, but he never published it. It would have been a good 

 name. The plant was named by Fee from Brazil many years ago, 

 and it seems to me there must have been 

 some transposition of the type, or the descrip- 

 tion in Saccardo. I have not seen the original 

 publication. It is difficult to understand how 

 he could have described it as "Stipes connate 

 at the base," "Clubs with the apices dilated." 

 The description as compiled in Saccardo must 

 apply to Xylaria. However, his type is at 



Paris, broken in pieces, and it is undoubtedly this plant. There are 

 also fragments at Kew (Fig. 816). As the name is quite applicable to 

 it, and is definitely fixed by the type in the museum at Paris and 

 Kew, there is nothing to do but continue it. Massee got a specimen 

 from Trinidad, which he named Daldinia aspera. It never was a 

 Daldinia, and as the original pieces of Fee's plant are at Kew, it 

 should not have been renamed there.
