^ciDiUM Phacelle. — Spots large, suborbicular, pallid or green- 
ish-yellow, becoming bro^yn ; peridia hypophylloiis, crowded, short, 
numerous, occupying the entire spot, crenulate on the margin; spores

C/EOMA CoiNiANDR.^. — Spores pale, indefinite; sori amphigenous, 
clustered, at first covered by the epidermis; spores subglobose, ovate 
or elliptical, orange-yellow, .00095 '^^ .0014 in. long, .0008 to .00095

Living leaves of Co?na?tdra pallida. Utah, Jones. 
Periconia GEOPHiLA. — Stem two to three lines high, composed of 
compacted filaments, smooth, smoky-brown; head hemispherical, 
pulverulent, little broader than the diameter of the stem, whitish or 
yellowish-white; spores subglobose, colorless, .0002 in. in diameter. 
Ground. Washington Territory, Brandegce. 
This species is peculiar in its habitat. By some authors it would 
be referred to the genus Sporocybe, the application of these two 
generic names having been interchanged by different writers. 
Dendrodochium pallidum.— Tufts small, .014 to .028 in. broad, 
suborbicular, depressed when dry, whitish or pallid; flocci slender, 
much branched above, colorless; spores abundant, large, oblong or 
subcylindrical, straight or slightly curved, obtuse, colorless, .0008 to 
.0015 in. long, .0004 to .0005 in. broad. 
Decaying wood, Canada, Prof. J. Macoun. 
The filaments are closely and abundantly, but irregularly branched 
above, so that the spores, which are terminal on the ramuli, are 
crowded together as if produced in large masses. 
Physarum multiplex.— Stems growing from a thin, subpersistent 
hypothallus, sometimes confluent at the base; longitudinally furrowed, 
equal or tapering upward, orange-red; sporangia small, irregular, 
numerous, confluent into subglobose gyrose^convolute heads, green- 
ish or yellowish-green, with single walls bearing numerous lime-gram^- 
les; knot-like thickenings of the capillitium very small, sparse, white 
or yellowish; spores globose, blackish-brown, .0004 in, in diameter. 
Decaying wood and bark. Ohio, Morgan* 
The species is related to Physarum polymorphurn, Mont., froiii 
which it is distinguished by its bright orange-colored stem and its 
very numerous small, confluent, greenish sporangia. 
Bees and Colored Flowers.— I noticed recently, in a paper of 
some pretension to scientific accuracy, that Mr. Darwin has shown 
that insects are attracted to flowers by their color or fragrance, and, 
therefore, anemophilous flowers are not visited by insects; and Mr. 
Darwin's experiment with the Lobelia was cited in which no flower 
was visited subsequent to the cutting off of the petals. Now Mr. Dar- 
win does not say this, and his views often suffer from the^ zeal 01 
those who believe themselves his followers, but have not his talen 
for accuracy in giving every statement about a case. What Mr. 
Darwin does say is that color is a '* chief '' guide, and this c'^^ 
scarcely be questioned. That it is some guide is certain. That it is 
not the only guide, he himself, with the remarkable candor so charac-
