4. Hypoxylon coriugatum (Ft'.). Sphesria corrugata, Fr. El. II. 70. 
Difformes, confluens, tuberculosum, rimoso-corrugatum, ater, 
intus cinerascens ; peritheciis profunde immersis, ostiolis papillae- 
formibus rugosis. Ascis cylindraceis. Sporidiis ellipticis, rectis 
curvulisve, fuscis, ‘008 X ‘0035 mm. 
On dead wood. 
Extending for 2 or 3 inches, rugose, indurated. 
9. Hypoxylon vixidi-zufum ( B . cfc Rav.) Hypocrea viridi-rufa , Berk. 
N. Amer. Fungi, 803. 
Major, subglobosum, congestum, viridi-rufum ; ostiolis im- 
pressis. Ascis linearibus. Sporidiis oblongis, continuis, fuscis, 
primum binucleatis (*012 x ‘004 mm.). 
On Alnus serrulata. North America (Carolina). 
Seems to have been referred to Hypocrea in error, since it 
possesess none of the features of that genus. 
11. Hypoxylon ovinum, Berk. in Herb. Kent. 
Hemisphaericum vel confluento-elongatum, purpureo-nigricans, 
durum, lasve, subnitidum, intus fuscum. Peritheciis stratosis, 
atris, subglobosis. Ostiolis obsoletis. Ascis cylindricis. Spori- 
diis ellipticis, fuscis, dein atro-fuscis, -016--018 X *007 mm. 
On wood. Orizaba, Mexico, and Tristan d’Acunha. 
20. Hypoxylon vera-crucis, Berk. & Che. 
Subglobosum, superficiale, saspe confluens (1-2 cm. diam.) laete 
rubiginosum, intus fuligineum. Peritheciis mediis, ovatis, peri- 
phericis, prominulis. Ascis cylindraceis. Sporidiis ellipticis, 
utrinque attenuiatis, fuscis (*02 x ’008). 
On rotten wood. Vera Cruz (Salle). 
33. Hypoxylon multiforme, Fr. var. australe, Cke. 
With the habit and external aspect of the typical form, at least 
of the most globose state, but the sporidia smaller (*008 X *003 
mm.). The difference seems to be scarcely specific. 
On bark and wood. Melbourne, Australia. 
37. Hypoxylon hians, BerTc. & Che. 
Hemisphaericum vel subglobosum, superficiale, atrum, nitidum, 
intus atro-fuligineum. Peritheciis magnis, subglobosis, conico- 
elevatis, ad apicem cupulato-excavatis, centro ostiolo papillato 
gerentibus. Ascis cylindraceis. Sporidiis ellipticis, obtusis, 
fuscis (*01- , 012 x *006-'007 mm.). 
On wood. Tasmania. 
Most distinct in the cup-shaped depression around the ostiolum. 
Stroma about an inch in diameter. 
40. Hypoxylon Hookeri, Berk, in Herb. Kern. 
Subglobosum, mox atrum (1 cm. et ult.) intus fuliginosum. 
Peritheciis magnis, globosis, elevatis; ostiolo papillato. Ascis 
cylindraceis. Sporidiis ellipticis, fuscis (*01 x ‘004 min.). 
On wood. India (Sir J. D. Hooker). 
Resembling H. majusculum , but the perithecia much larger, and 
more prominent, in which latter respect it approaches H. annu- 
latum.
