Gen. 2. PORONIA. Fr — Handbk., p. 791. Species, No. 2,379. 
Gen 3. THAMNOMYCES. Ehr . — Handbk., p. 792. Species, 
No. 2,380. 
Gen. 4. USTULINA. Tul.— Handbk., p. 793. Species, No. 2,381. 
Gen. 5. HYPOXYLON. *V— Handbk., p. 793. 
Sub-gen. 1. DALDINIA. Not. — Stroma superficial, subglobose, 
smooth, concentrical within. Handbk., No. 2,384. 
Sub-gen. 2 PULVINATA. Nr . — Stroma convex, somewhat hemis- 
pherical, papillate. Handbk., Nos. 2,385 to 2,390. 
Hypoxylon majusculum. Cke • — Globose, often confluent, reddish 
brown, then black ; perithecia ovate ; stroma sooty black ; ostiola 
at length prominent; sporidia elliptical, often curved, slightly 
narrowed at each end, dark brown. *018 X *007mm. Hyp. multi- 
forme. var. ; Cooke, F. Britt, i., 374.— On decayed wood and bark. 
This is the Hypoxylon fragiforme var. major , of Berkeley, but 
the sporidia in that species are only *01-012 x ’005-*006 mm., 
hence it is proposed as a distinct species. 
Sub-gen. 3 EPIXYLON.— Stroma superficial, effused. Species, No. 
2,391 to 2,394. 
Hypoxylon miniatum . Che. 
Effused, irregular, convex, tawny brown; perithecia connate, 
ovate, slightly papillate; stroma bright orange-red; sporidia 
broadly elliptical, flattened on one side, brown, -01 X *005-*006 
mm. 
On decorticated sticks. 
It is difficult to refer this to any known species, the bright 
stroma being so very distinct.

Gen. 7. EUTYPA. Tul— Handbk., p. 798. Species No. 2,396

Gen. 8. DIAFORTHE. Nike, (in part). 
Stroma formed of the discoloured matrix ; perithecia gregarious 
in definite spots, or broadly effused, often circumscribed by a black 
line ; when covered, forming definite discoloured patches, rostel- 
late, erect, not convergent, or united into a disc ; sporidia hyaline, 
often narrowly fusiform and quadrinucleate. 
This genus is not accepted in the sense usually adopted on the 
continent, that is, including within it all species, whether of 
Diatrype or Valsa , liaviug quadrinucleate sporidia, but — having
