of mere flocculent dust. The spores are at first short and simple, but 
they soon become uniseptate and then longer and mostly triseptate.

Aspergillus clavellus, . sp. (Plate %, figs. 1-5.) Sterile flocei 
creeping, abundant, soft, white; fertile flocci erect, gradually enlarged 
above into an oblong-elliptical or clavate head; head at first white, 
then glaucous-green; spores globose or broadly elliptical, smooth, 
00016 in. to .0002 in. long. Cooked squash. Albany, Oct. This 
species, by the clavate apices of the fertile flocci, is related to A. mollis, 
but that species is white and has the fertile flocci branched and the 
spores large. In color, our plant resembles A. glaueus, but that has 
the apices of the fertile floeci globose, and the spores, according to 
Corda, much Jarger and rough. 
Monilia Harknessii, 7. sp. Flocci tufted, slender, tawny, breaking up 
into elliptical or lemon-shaped spores, .00025 in. to .0004 in. long, 
about .0002 in. broad. Decaying wood. Helderberg mountains, 
Nov. This fungus is related to and congeneric with such species as 
Oidium aureum, O. fuluum and O. pulvinatum, but if the genus 
Oidium is to be limited to such fungi as grow on living vegetable 
tissues, as some mycologists hold, then the species just mentioned and 
the one just described must be referred to the genus Monilia. 
Colletotrichum lineola, Cd. Old corn stalks. Chatham, Columbia 
county. June. Sometimes this fungus isso abundant that the patches 
surround the whole stem and appear to clothe it with a thin blackish 
pubescence, though the flocci have a tendency to arrange themselves in 
parallel lines. It is this tendency apparently which suggested the 
specific name. The gelatinous subiculum which is said to exist is not 
at all apparent in our specimens. ‘The spores vary somewhat, being 
in some instances about equally pointed at both ends, in others they 
are much more pointed at one end than at the other. Psilonia 
apalospora, B. & R., and Vermicularia velutina, B. & R., according to 
my Curtisian and Ravenelian specimens are very closely related to each 
other and to this species if indeed they are really specifically distinct. 
Sporocybe nigriceps, ». sp. (Periconia of some authors.) Plant 
black, .025 in. to .03 in. high; stem erect, shining, smooth, septate, 
sometimes with one or two short thick branches at the top; head 
globose or elliptical ; spores globose, minutely rough, colored, .00025 
in. to .00035 in. in diameter. Dead leaves of sedges and carices. 
Albany and Adirondack mountains. Julyand Aug. ‘l'woforms occur, 
sometimes growing on the same leaf. In one the head is larger, 
elliptical in outline and nearly as long as its stem, which has but one 
or two septa. In the other the head is smaller and nearly or quite 
globose and the proportionally longer stem has several septa. Sporocybe 
nigrella is said to inhabit dead leaves of grass, and WS. cholorocephala, 
dead leaves of carices. I am not acquainted with either species, but 
as both are described as having smooth spores our plant cannot well 
be referred to either of them. An unfortunate disagreement exists 
among European mycologists in the application of the generic names 
Sporocybe and Periconia. The English mycologists employ the former
