Godronia Cassandra, 7. sp. 
Receptacle small, .02 to 03. in. broad, sessile or nearly so, depressed, 
urceolate, tawny-brown, the hymenium whitish orslivid when moist, 
darker when dry, the narrow mouth entire or slightly dentate-lacerate, 
almost closed when dry ; asci cylindrical, .0045 to .005 in. long, .0003 
to .0004 broad ; spores filiform, nearly straight, .002 to .003 in. long ; 
paraphyses filiform, numerous. 
Dead branches of leather leaf, Cassandra calyculata, Karner, Aug. 
Tympanis saligna, Tode. 
Dead branches of willow, Salix purpurea. West Albany. Apr. 
The specimens are without fruit and to this extent doubtful. | 
Stictis Saccardoi, Rehm. 
Dead stems of scouring rush, Hyuisetum hyemale. Delmar. Sept. 
Lichenopsis spheroboloidea, Schw. 
Dead stemsof Cornus. LElizabethtown. May. 
Asoomyces extensus, P/. ; 
Spots large, irregular, brown, usually somewhat convex above and 
concave below, most frequently occurring at the apical end of the leaf 
or of its lobes ; asci hypophyllous, cylindrical, obtuse or subtruncate, 
.002 to .0025 in. long, .0009 to .0011 broad ; spores globose or broadly 
elliptical, variable in size, .00016 to .0003 in. long, .00016 to .00025 
broad. 
Living leaves of the over-cup oak, Quercus macrocarpa. Platts- 
burgh. July. Gen. J. M. Robertson. 
The specimens were first sent by Gen. Robertson to the editors 
of the Country Gentleman, with the information that nearly every 
leaf on the tree was affected in a manner similar to those sent. In 
these the dead spots occupied one-fourth to one-half the entire leaf. 
They number from one to three spots on a leaf. It is very evident 
that the vital functions of leaves so extensively affected must be much 
impaired, and that the health and vigor of the tree must be corre- 
spondingly weakened. It was also stated that many other oaksin that 
region were similarly affected. The species is distinct from A. Quercus 
Cke., in the character of the spots and also of the spores. 
Microspheria Ceanothi, (Schw.). 
Living leaves of New Jersey tea, Ceanothus Americanus. New 
Scotland. Oct. . 
This appears to be the fungus described by Schweinitz as Hrysiphe 
Ceanothi, although the perithecia in our specimens can scarcely be de- 
scribed as ‘‘ immersed ” and the species is a Microspheria, not an Ery- 
siphe. It is closely related to M. penicillata, having about four eight- 
spored asci in a perithecium, but it differs from that fungus in occur- 
ring only on the upper surface of the leaves. It sometimes attacks 
the immature fruit which it covers with a more dense white mycelium.
