Tke result of these cultures is to impress one with the close rela- 

 tioiishii) of this Gloeosi3orium on the privet to the GloeosiK)rinm 

 fructigenuin on apples. If it were the same species the cultivation 

 of the privet would then bear a new and imiK>rtant relation, per- 

 hai>s, to the spread and jiropaj^ation of the rii>e rot of api)l('s. 

 Thei*e are points of difference, however, so far as the two species 

 are at present known, sufficient to charaxiterize it as a hitherto 

 undescribed species, and I propose for it the name Gloeosporium 

 cingulatum, or the girdling anthracnose. 



Gloeosixt'riuin cingulatum ns. p. Affected areas light bi'own, 

 either oblong and on one side of the stem or later completely gird- 

 ling it. Acervuli 100 to 150 in diameter, rupturing the epidemiiis, 

 iu age black from the dark stroma lying in the base or extending 

 irregularly up the sides frequently forming a pseudo-pycnidium. 

 IJasidia numerous, crowded, simple, hyaline or when very old 

 perhaps faintly fuliginous. Spores oblong, or elliptical straight 

 or little cuiTed, usually pointed at the base. From ])ustules on 

 the stem the measure 10 — 20x5 — 7; in artificial 

 cultures they are frequently much larger, but when croA^ded in 

 the media, or when the nutrient substances are nearly exhausted, 

 they may be considerably smaller — on stems of Ligustnim 

 \ulgare.

NOTE ON THE CEKCOSPORA OF CELERY BLIGHT. 



Late in September, specimens of celery alfecttMl by " celery 

 bliglit,'' sent by 11. C. Townsend of Wa])j)inger's Falls, Dutchess 

 (•(Hinly, were communicated to me by Mr. Turner of the New York 

 >Yea1)lier Sen-vice. The disease was detenuined as due U> the 

 fungus (3ercosiM)ra Apii Fres. A short nc^te on the diij<'ase was 

 then ]Miblislied in the Crop Bulletin of the New York Weather 

 Service, for the week ending September 24, 1S92. It has long been 

 known in Eurojje and has been recorded several times in various 

 .I)arts of the IMted States during the past several years. It some-
