In the ‘‘ Flora Nov^e-Zelandise” of Dr Hooker there is no record of 
any species of Opegrapha, Platygrapha, Umbilicaria^ or Ahrothallus ; 
and Professor Churchill Pabington therein specially remarks, in- 
deed, on the supposed absence of the genera Opegrapha and Umbili- 
caria (Gyrophora) from the Lichen-Flora of New Zealand. Sub- 
sequent researches have, however, shown that these genera are really 
represented, their apparent absence having been due probably to 
their not having been specially looked for. The foregoing list ex- 
hibits three species of Opegrapha^ all new, being all the Opegraphm 
contained in the author’s collection ; and Dr Knight and Mr Mitten 
have described other three species,* two of them new, as occurring 
in the North Island. The author’s Otago collection also contains 
at least one species of Umbilicaria — a British one — TJ. polyphylla, 
L., and he has little doubt others will be discovered when the 
Lichens of the New Zealand Alps are specially collected. 
II. Fungi. 
1. Sphaeria Lindsay an a, Currey. 
2. S. Otagensis, Linds. 
3. S. Martiniana, Linds. 
4. S. perrugosaria, Linds. 
5. S. Cargilliana. Linds. 
6. S. TJsnearia, Linds. 
7. Sphseria vermicularia, Linds. 
8. S. Ramalinaria, Linds. 
9. S. Stictaria, Linds. 
10. Nectria armeniaca, Currey. , 
11. -iiEcidium Otagense, Linds. 
Of these. Nos. 4 to 9 are types of a group, which is as yet virtually 
unknown to Fungologists, viz., the Fungi parasitic on Lichens; while 
No. 11 possesses interest in connection with the deformities or 
diseases it produces in the Phmnogamous plant which it affects.

The Council reported that they had awarded the Keith Prize for 
the biennial period 1863-65, to Principal Forbes, St Andrews, for

in Iron Bars,” which was printed in the last Part of the Transac- 
tions of the Society. 
The Council also reported that they had awarded the Neill Prize
