1907] SHEAR & WOOD—ASCOGENOUS GLOEOSPORIA 261 
fungi, but until we have had opportunity to study the types of the 
genera to which they may belong, we prefer to use the name Glomer- 
ella for at least all the species which are known to have ascogenous 
stages congeneric with Glomerella rufomaculans (Berk.) Spauld. & 
v. Schrenk. 
The first published work on the life-history of these fungi was that 
of Miss STONEMAN, in 1898; she worked with twelve forms from as 
many different hosts, and succeeded in producing in pure cultures 
both the conidial and ascogenous stages in four cases, and a doubtful 
fifth, as follows: 
Glomerella cingulata (Stoneman) Spauld. & v. Schrenk, the conidial stage 
occurring on privet (Ligusirum vulgare); G. piperata (Stoneman) Spauld. & 
v. Schrenk, the conidial stage found on pepper, Capsicum sp.; G. cincta (Stone- 
man) Spauld. & v. Schrenk, the conidial stage occurring on an orchid, Maxil- 
laria picta, and provisionally referred to Colletotrichum; G. rubicola (Stoneman) 
Spauld. & v. Schrenk, the conidia from red raspberry, Rubus strigosus; G. (?) 
Vanillae (Stoneman) Spauld. & v. Schrenk, the conidia from the cultivated 
vanilla. 
Miss STONEMAN referred all these species to a new genus, which 
she named Gnomoniopsis. This name was untenable, however, 
having been previously used by BERLESE'® for another genus of 
fungi. CLINTON (/.c.) in 1902, seems to have been the first to obtain 
in pure cultures the ascogenous stage of the Gloeosporium causing 
anthracnose or bitter-rot of the apple. VoN ScHRENK and SpAULD- 
ING (/.¢.) in 1903, and Scorrt (/. c.) in 1906, also worked with the apple 
Gloeosporium and made additions to our knowledge of its life-history 
and conditions of development. SHELDON (/.c.) in 1906, reported the 
successful growth in pure cultures of the ascogenous stage of the 
guava anthracnose or ripe-rot, Glomerella Psidii (Del.) Sheldon. 
These six forms are the only ones whose life-histories have heretofore 
been determined by pure culture methods, so far as we have been 
able to learn from published records. 
The present writers have studied a number of forms and have 
succeeded in growing both the conidial and ascogenous stages from 
eight different hosts, as follows: 
Gloeosporium rufomaculans (Berk.) v. Thiimen, from the cultivated grape, 
Vitis sp.; G. fructigenum Berk., from the apple; an apparently unnamed Gloe-
