Pluteanae, or rosy-spored series ; the Pholiotanae, or rusty- 
spored series ; and the Agaricanae, in which the spores are brown 
or black in mass. Two new genera are included, Marasmielliis 
and Polymarasmius, each with three species. Another new genus 
of the Lepiotanae, Lentodielhim, containing a single tropical 
species, occurs in the, key but the description had to be reserved 
for the first page of Volume 9, part 5.

The Validity of Clitocybe Megalospora 
The writer has recently had an opportunity to examine the • 
type specimen of Clitocybe megalospora Clements (Bot. Surv. 
Neb. 4: 18. 1896), which was collected on wet earth at Saltillo, 
Nebraska, July 7, by Pound and Clements (No. 4239) ; and he 
was surprised to find it identical in every respect with four col- 
lections obtained by him several years ago in Virginia, Tennes- 
see, and Pennsylvania. The description of Clitocybe megalospora 
corresponds to that of Collybia radicata, the lamellae being de- 
scribed as white or yellowish and the spores as hyaline and very 
large, reaching 17-18X10-12/11. The plants collected by the 
author in \^irginia and elsewhere were in each case determined 
when fresh as undoubtedly Collybia radicata and the accompany- 
ing field notes described them as sticky when moist, white, with 
yellowish center and white lamellae. 
It was not until several years later, when these specimens were 
examined in the herbarium, that the lamellae were found to be 
brick-red and a microscopic mount from the lamellae apparently 
showed a mycelium bearing enlarged red tips rounded off at the 
apex, which seemed to become constricted and separate as spores. 
It is difficult to make a microscopic study of this kind from dried 
material, and further study was deferred with the hope that 
additional material might be found in the fresh state. The type 
of C. megalospora upon microscopic examination showed the 
same reddish bodies and the lamellae were partly colored red by 
them. It is possible that we have here an interesting micro- 
scopic organism which changes the color of the lamellae, but why 
this occurs after the specimen is collected and dried is not so 
clear. Many of the rosy-spored gill-fungi have whitish lamellae
