This species is said to differ from the preceding in its smaller 
and more regularly-shaped stroma, with the perithecia confined mostly 
to the central portion of the disk and by its habitat on bare wood, and 
not on bark; the stroma is also said to be of a darker color, without any 
olive or greenish shade. We are inclined to think that these points of 
distinction are due to imperfect development and are not of specific 
value, and we have examined many specimens, as the species ( as repre¬ 
sented in N. A. F. and Rav. F. Am.) is very common, both around 
Xewfield and West Chester. Both 11. ScJiweinitzii and H. rigenfi are 
distinguished from H. lenta (Tode) by their smaller sporidia. 
25 . IIypocrea scuTp:LLAi:FORMis, B. & Rav. (Rav., Fungi Car., 
IV.,Xo. 81.) On bark of Acerruhrum. Carolina. (Ravenel.) 
Stromata scutellate, centrally attached, margin free and, in the larger 
specimens, undulate and sublobate, 1—2 millim. across, convex, nearly 
smooth, only slightly punctate from the scarcely prominent ostiola, 
color dull red; cells of the sporidia subglobose, 3—4 r- in diam. Our 
knowledge of this species is derived from the specimen cited, in which 
the asci had disappeared, but the globose cells of the sporidia were 
abundant. 
In Grevillea XII, p. 78, it is stated that H. scutellcefoi'mis, B. & C. and 
H. liavenelii. Berk., in Rav., Fungi Car., are two names for the same 
species, but in our copy of the collection cited, the sporidia are, as above 
described, entirely different from the brown, fusoid, 8-septate sporidia 
of IT. Harenelii, Berk.
