Report OF THE BOTANIST. 59 
MELANCONIUM DISSEMINATUM F7. 
Decaying wood. Richmondville and Hunter. June and 
July. 
The masses of spores often occupy the summit of little 
protuberances of the wood, as if the fungus prevented or 
retarded the decay and wasting away of the woody tissues 
immediately beneath it. : 
MELANOONIUM OBLONGUM B. & C. 
Bark of butternut trees, Juglans cinerea. Greenbush. 
May. 
MELANCONIUM MINUTISSIMUM Sehw. 
Bark of Platanus occidentalis. Buffalo. Clinton. April. 
CORYNEUM DISCIFORME 0Q7. ELLIPTICUM B. & Br. 
Dead birch branches. Yonkers. Howe. 
CorynEuM Kunze Cd. 
Dead branches of white birch, Betula populifolia. West 
Albany. May. 
PESTALOZZIA INSIDENS Zab. 
Bark of Elm trees. New Baltimore. Zabriskie. Hunter, 
Greene county. April and June. 
The spores in this species are .0011’-.0015’ in length, 
exclusive of the long bristles at the extremities. There are 
‘ generally four central colored cells. 
PESTALOZZIA ROSTRATA Zab. 
Bark of Lonicera and of apple trees. New Baltimore. 
Zabriskie. 
Externally this species closely resembles the preceding, 
but the spores are smaller, being .001’ long, and have no 
bristle at the base. There are usually four central colored 
cells. I cannot distinguish the spores of this from those of 
P. concentrica B. & &., from which, therefore. it differs 
only in habit and habitat, and to which it ought perhaps to 
be united. 
PrstaLozzia PrcKit Clinton n. sp. ) 
Pustules thickly scattered over the surface of the leaf or 
over indefinite grayish spots, erumpent, black; spores
