cc. Terminal ehlamydospores absent. 
d. Intercalary ehlamydospores present. 
e. Sporodochia typically absent. Conidia, when free- 
borne on aerial mycelium, spindle-shaped. 
Macroconidia gradually attenuate, generally 
lanceolate, apedicellate; but also sickleshaped 
and pedicellate; color intermediate between 
that of Roseum and Gibbosum sections, scle- 
rotia may be present_Sec. 5, Arthrosporiella. 
ee. Sporodochia typically present. 
f. Macroconidia with top ends much attenu¬ 
ated; stroma typically brown, 9 sometimes 
carmine 10 _Sec. 6, Gibbosum. 
ff. Macroconidia with top ends somewhat trun¬ 
cate; conidia ochreous to salmon; stroma 
Roseum-like; blue sclerotia may be pres¬ 
ent_Sec. 10, Discolor. 
dd. Intercalary ehlamydospores absent. 
e. Top ends of macroconidia gradually attenuate; 
when free-borne on aerial mycelium, sickle¬ 
shaped; or none. Acid-color modification of 
aerial mycelium yellow except in F. anthophilum 
(A. Br.) Wr., and other related fungi; conidial 
walls thin_Sec. 7, Roseum. 
ee. Top ends of macroconidia somewhat constricted, 
f. Conidial walls thin,, and in this character, 
as well as in shape and color, similar to 
section Elegans_Sec. 9, Lateritium. 
ff. Conidial walls thick, highly refracable, and 
in this character, as well as in shape and 
color, similar to section Discolor; conidial 
stage of Gibberella saubinetii and other 
similar Gibberellas_Sec. 12, Saubinetii. 
RELATIONSHIP OF FUSARIA TO ASCOMYCETES 
A number of different species of Fusaria have been definitely connected with 
certain ascomycetes of the Hypocreales group. In some other cases the connec¬ 
tion is very probable, and in still other cases the connection is suggested as possible. 
For convenience the instances are mentioned here under different sections of the 
genus Fusarium. 
Sec. 1. Eupionnotes. Perfect stage, Nectria moschata Gluck, conidial stage 
* similar to F. aquaeductuum Lagh. var*. pusillum Wr. 
Sec. 2. Arachnites. Perfect stage, Galonectria graminicola (Berk. & Brome) 
Wr., conidial stage F. nivale (Fries) Ces. 
Sec. 3. Sporotrichiella. No connection with an ascomycete is known. 
Sec. 4. Camptospora. Perfect stage Nectria episphaeria (Tode) Fr., conidial 
stage may be F. cavispermum Cda. 
Sec. 5. Arthrosporiella. No definite connection with an ascomycete is known . 
Sec. 6. Gibbosum. No connection with an ascomycete is known. 
Sec. 7. Roseum. Gibberella tropicalis Rehm. possibly has Roseum-like conidial 
stage. 
Sec. 8. Liseola. Gibberella acervalis (Moug.) Wr., conidial stage very similar 
to F. moniliforme Sheld. 
Sec. 9. Lateritium. Gibberella baccata (Wallr.) Sacc., conidial stage F. later¬ 
itium Nees; G. pulicaris (Fr.) Sacc., conidial stage F. sarcochroum (Desm.) 
Sacc.; G. moricola (Ces. et Not.) Sacc., conidial stage F. urticearum (Cda.) 
Sacc.; G. effusa Rehm, conidial stage F. salicis Fuck.; G. evonymi (Fuck.) 
Sacc., conidial stage F. pyrochroum (Desm.) Sacc.; G. juniperi (Desm.) Wr., 
conidial stage F. fructigenum Fr. 
Sec. 10. Discolor. Gibberella heterochroma Wr., conidial stage F. polymorphum- 
like; and G. cyanogena (Desm.) Sacc., conidial stage F. sambucinum Fuck. 
Sec. 11. Spicarioldes. No connection with an ascomycete is known. 
Sec. 12. Saubinetii. Gibberella saubinetii (Mont.) Sacc., conidial stage F. 
cramincarum Schwabe; G. flacca (Wallr.) Sacc., conidial stage F. caricis Oud.
