variable number and variety of micro-organisms were normally 
present on the surface of flowers, fruits and leaves. These were 
different in different localities, and different in successive years in 
the same locality, and showed no constant association with the host 
plants studied. . . . The most constantly present organisms were 
certain yeasts; in greatest number and variety on the peach, 
asparagus and iris; bue yet characteristically present on the cere¬ 
als. . . . Bacteria giving the standard reactions of the colon 
group were found in thirteen out of sixteen rice fields examined, 
five of the eight wheat fields and all of the oat fields. All three 
peach orchards and both asparagus patches exhibited coli forms 
in both flower and fruit; but none were found on either flower 
or fruit of Iris verna. 
A PRELIMINARY NOTE ON CLOVER DISEASES IN TENNESSEE 
by Samuel M. Bain and Samuel H. Essary, Science, N. S., 22: 
503, October 20, 1905, refers to the prevalence, greater or less, 
of Uromyces trifolii, Pseudopeziza trifolii, and Macrosporium 
sarcinaeforme but the author says: The most destructive disease 
thus far found is what appears to be an undescribed species of 
Colletotrichum. In its general appearance this disease very 
closely simulates the anthracnose of clover (Stengelbrenner ), 
described by Mehner and Kirchner and by the latter attributed 
to the attacks of Gloeosporium caulivorum n. sp. 
Two CONIDIA-BEARING FUNGI, CUNNINGITAMELLA AND 
Thamnocephalis n. gen., by A. F. Blakeslee, (with plate), is 
the first article in the September No. of the Botanical Gazette, 
1905. The first species discussed is C. echinulata Thaxter, sel¬ 
dom reported, and the second is Thamnocephalis quadrupedata, 
growing in a gross dung cluture on fresh sphagum. The new 
genus is characterized as follows: Thamnocephalis. — Vegetative 
hyphae fine, continuous, anastomosing. Fructifications erect, 
consisting of a main stalk supported above the substratum by 
stout rhizoidal props and bearing a bushy crown of subdichoto- 
mously branched fertile hyphae terminated by sterile branches. 
Spores solitary, borne on the surface of spherical heads. Heads 
borne at the apex of short lateral stalks which arise at nodes 
from opposite sides of the fertile hyphae at right angles to their 
planes of branching. 
Chroolepus aureus a Lichen, is what Albert Schneider 
maintains in the August (1905) No. of the Bulletin of the Torrey 
Botanical Club. Material collected at Vancouver Island presented 
opportunity for the study, and here is his conclusion: There 
seems to. be little doubt that the network described represents a 
fungus symbiotically associated with the alga Chroolepus aureus. 
This association appears to be sufficiently constant to warrant 
placing this structure, heretofore classed as an alga, with the 
class Lichenes. The fungal symbiont does not appear to develop
