name is not sufficiently distinctive. Hence, we propose the name 
Sporotrichum bud-rot. 
Up to the time of the discovery of the true nature of the bodies 
supposed to be insect eggs it had not occurred to us that our dis- 
ease might be the same as that described by Heald’? under the 
caption, “ Bud-rot, Fusarium anda Mite.” But it was now observed 
that our mite agreed with Heald’s description of the mite found by 
him. At our request, Dr. Heald kindly sent us (April, 1907) four 
carnation blooms affected with this bud-rot. Three of these blooms 
were identically like those from Long Island —they showed an 
abundance of Sporotrichum free from admixture with any other 
fungus and there were also present mites which were pronounced 
by Mr. Hodgkiss to be the same as those found in the Long Island 
specimens. The fourth bloom, also, contained an abundance of Spo- 
rotrichum and some mites, but in addition thereto a considerable 
number of pluri-septate, hyaline, Fusarium-like spores. By means 
of dilution cutures in potato agar, an attempt was made to isolate 
both the Sporotrichum and the Fusarium. Pure cultures of the 
former were obtained easily, but the Fusarium was elusive. A 
further discussion of this subject appears on page I55.

June grass, Poa pratensis L., is a very common grass in New 
York particularly along the highways and railroads. When it 
begins to ‘‘ head” in the latter part of May a large percentage of the 
panicles wither before they become fully expanded. Affected pani- 
cles are conspicuous because of their light color. One accustomed 
to observe such things can scarcely fail to notice the trouble when 
it is at its height during the last week in May and the first half 
of June. At that time it is abundant all over the State. A very 
little investigation. of the affected plants suffices to show that the 
seat of the trouble is, in most cases, Just above the uppermost node. 
Here, the tender portion of the culm is badly shriveled (but not 
noticeably gnawed) over a section 5 to 10 millimeters in length. 
This may be readily observed by ‘gently pulling one of the withered 
panicles from its sheath. (See Plate XI, fig. 3.) Sometimes the 
injury instead of being at the uppermost node is at the next one
