der of dull red brown, 3 — 5 mm. long. Hyphse amphige- 

 nous, loosely fasciculate, tufts irregularly scattered and few 

 in a spot, bright reddish brown, septate, nearly straight to 

 subflexuous and sparingly toothed near apex, 40 — 65 X 

 3, 5 — 4. Conidia hyaline, i — 7 — septate, terete, straight' 

 or little curved, 10 — 60 X 2, 5. 



On leaves of Agrostis, 2036, Auburn, July 23, 1891, 

 Duggar and Newman. 



12. Cercospoka citrullina Cke. On leaves of water- 

 melon {LHtrulhis vidgaris\ 1581, Sept. 3, 1890, x\tkin- 

 son. Specimens are not now at hand, not having been 

 preserved. It agrees well with Cooke's description (Grev. 

 XII, p. 31). The only notes I have in my record are as 

 follows: "Amphigenous, conidia several times (5 — 9) sep- 

 tate. Affects leaves near base of stem first and gradually 

 progresses toward other extremity." 



13. Cercospora Cucurbit.^ E. & E. Spots suborbicu- 

 lar, amphigenous, subochraceous, then whitish bordered 

 by brown, 2 — 4 mm, Hyphse epiphyllous, fasciculate, 

 dull olive reddish brown, lighter tow^ard apex, septate, sub- 

 geniculate and sparingly toothed or scarred toward apex, 

 70 — 200 X 4 — 4, 5- Conidia hyaline, slender, terete, 

 straight or curved, multiseptate, 50 — 120 — 200 X 3 — 4. 



On leaves of "dish-rag" squash, {Cticiirbita ?) 2154^;, 

 Auburn, 1890, Atkinson; Lagenaria vulgaris^ 2154, Sep- 

 tember 10, 1 89 1, Duggar. 



This may be identical with C. citrullina Cke. 



14. Cercospora pachyspora E. & E. Spots amphige- 

 nous, dark brown with concentric elevated lines and indefi- 

 nite yellowish border, suborbicular, 4 — 10 ;;/w. Hyphse 

 amphigenous, more numerous below, fasciculate, stout, 

 dilutely ochraceous, septate, flexuous, when young nearly 

 hyaline, 50 — 100 X 5 — 9. Conidia hyaline or dilutely 

 yellowish, obclavate, 3 — 8 septate, 25 — 100 X 8 — 10.
