ON THE PILOBOLIDiE. 
V. cedipus , and then remarks, witli surprise, that Corda had 
represented the spores of his P. crystallinus as elliptic and 
colourless “ in contradiction to nature.” 
Cesati discovered, in 1850, a species, which he published 
in the next year under the name of P. anomalus. 1 
Bonorden, in 1851, describes 2 a species, under the name 
of P. crystallinus , which on account of its round spores 
Coemans refers to P. cedipus , but which I think there is 
greater reason for considering a peculiar form of P. Kleinii. 
In 1856 Currey wrote a note “On a Species of Pilobolus,” 3 
which he considered to be P. roridus , but his plate and 
description clearly show that the species he had in view was 
P. Kleinii. He was probably led into this error by Cohn’s 
monograph, which puts forward P.. cedipus as the true crystal- 
linus , but, whatever its cause, it has occasioned serious 
inaccuracies in the British records. Leveille, in 1826, had 
fallen into the same error, giving, according to Van Tiegliem, 
the name of P. roridus to a mere form of P. Kleinii. Currey 
also erroneously attributed the projection of the sporangium 
to the eversion and upward pressure of the columella. 
In the “ Outlines of British Fungology ” (1860) Pilobolus 
is omitted altogether. 
In 1861 Coemans published his “ Monograpliie du Genre 
Pilobolus,” in which he summarises all that had previously 
been done on this subject, and gives a list of all the species 
referred by other authors to this genus. He considers 
P. crystallinus and P. cedipus to be the only certain species ; 
P. roridus he regards as doubtful, P. lentiyerus he refers, 
wrongly, to P. cedipus, and P. anomalus he places in the genus 
Ascophora, by the name of A. Cesatii.

Du. J. J. Woodward, whose excellent plioto-micrographs, produced 
during his connection with the Army Medical Museum, Washington, 
are well known, is dead. Dr. Woodward many years since undertook 
an examination of the microscopic test plates ruled by the late 
F. A. Nobert, of Prussia, in which he was eminently successful. He 
subsequently made a large series of photo-micrographs of test objects, 
such as blood corpuscles, on a micrometer plate, so that the diameters 
could be estimated by inspection, his latest work being the production 
of photo-micrographs of the diatom Amphipleura pellucida. — Atlienccum.
