NUMMULARIA AND ITS ALLIES. 
5 
Scliweinitz cannot be synonymous with Nummularia Bulliardiy to 
which it is referred. 
Measurements. — 
Nummularia discreta, Tui. ( 1529 ). 
We have seen no specimens in which the sporidia approximate 
to •015-'018mm. The usual dimensions we have recorded are 
*013 X '01 mm. 
Nummularia obularia, (Fr.) ( 1540 ). 
Sporidia *008 x ‘003 mm. 
Nummularia clypeus, 8chwz. ( 1524 ). 
Sporidia *020-*021 x *008-*01 mm. 
Nummularia gigas, Plow. ( 1531 ). 
Our measurements certainly do not exceed *006-'007 X *003 mm. 
Emendations. — The following species will have to be excluded 
from this genus : — 
1532. Nummularia frustulosa (B. & C.), Sacc. 
Will be Xylaria frustulosa (B. & C.) 
1533. Nummularia Wrightii (B. & 0.) 
Must stand as Hypoxylon Wrightii, B. & C. 
1534. Nummularia punctulata (B. & Eav.) 
Must remain as Hypoxylon punctulatum, B. & Eav. 
1535. Nummularia placentiformis (B. & C.) 
Will still be Hypoxylon placenti forme, B. & G. 
1536. Nummularia subo rbicul aris (W. & Curr.) 
Eemains as Hypoxylon suhorhiculare, W. & C. 
1542. Nummularia spondylina (Fr.) 
From the specimens we have seen this has no affinity with the 
present genus, and is therefore Hypoxylon spondy linum, 
Fr. 
1544. Nummularia Artemisiae (Schw.) 
Is a Dothidea with tetrasporous asci and uniseptate brown 
sporidia '016 x '007 mm., according to specimen from 
Schweinitz. It will stand as Dothidea Artemisiae 
(Schwz.) 
1545. Nummularia subaffixa (Schwz.) 
Has hyaline allantoid sporidia '008 mm. long. It will be 
Diatrype subaffixa (Schw.), and is an ally of Diatrype 
stigma, Fr. 
The above alterations are made, as we believe, entirely in the 
spirit of Professor Saccardo’s interpretation of the genus. Such 
species as Hypoxylon cerebrina. Fee., Hypoxylon Wrightii, 
B. & C., Hypoxylon suborbiculare, W. & C., and some others, 
could not possibly be regarded as having any relationship to the 
species now included. There are some four or five species in- 
cluded in our list, which we have never seen, and these are included 
on the faith of the diagnoses, in which we have followed Saccardo. 
Additions. — The following diagnoses of species not included 
in the “ Sylloge,” under any name, will be found supplemented by
