 elie.stnut, in .i']urope, and ])refers a southern hahilat, wjiat of : 

 jn'eferenees in this country? From an examination of litoratuir 

 and of specimens in the \ew York iJotanical (Jai-deus, it is ap 

 parent that iUnloiliia f/i/ro-sa has been reported much more fi' 

 (|ueiilly south of Feiinsyhania than north of it. l"'or two years, 

 1 and otliers liave been liMtkinu- for it in Connecticut, and on' 

 tbis winter "svas it found by oui- forester. This sjx'ciuu'U, lik^ 

 those reported by A>'iuter from (Jermauy, lias only its pycnidial 

 stage, thouiih this is tlie time of year to tiud the asro-stage. Eii- 

 iJofliid f/i/rosa lias been found on as nuiuy hosts in this count ly 

 as in P]uro])e, and likewise chieliy from the south. \\'liy may we 

 not then (ixpect to find it there on the chestnut? \\'e certainly 

 luive had trouble enouj^h with the chestnuts in the South in f(»i- 

 nier years to believe that it miulit occur there.* 



The second point expressed in my view is thai the chestnut 

 bliiiht funuus is also a native of Furope. Urietly stated, my rea 

 sons for this lielief are: ll) The specimens in deThueman's 

 exsiccati on chestnut in Italy already referred to; (2) the state- 

 ment of Professor Farlow that he has seen identical hei-bariuiii 

 specinu'us of it from p]uroi)e; and HV) a recent letter from Tro- 

 fessor Saccardo of Italy, who states that he ami l*rofessor IIoli- 

 nel simultaneously recoiiuized that DUiporlhc jKiriisUiat ,Murr. 

 is the same lliinii' as Fjinloilihi flUioxu. l.'otli in its ascospoi-e and 

 conidial stajies. A critical study of more specimens on all hosts 

 from each ccnintry may, however, settle diffei-eiit ly some points 

 at present not clear to me.

 its exaet relationship is to liiaiioitha jxiidnilirn has not yet lieen full.v determined. In gros-; 

 l)earanee its fruiting pustules are scarcely different, except iinssilily slightly le.ss Inxmi.i 

 as a rule. Its pycnidial spore.s or Cytosp^ira stage is apparently identical with that of /'. / 

 silica, hut the asco-sporcs are evidently as a whole less luxuriant: that is, thev are soim v 

 smaller, and especially slightly narrower. Whether these differences are those ot a strain, vari' i- 

 01' distinct. species, is yet to be deteniiiuetl by cultures, inociilatioaa, and further study.
