30 PARASITES BELONGING TO THE GENUS GLOMERELLA. 



CURCULIGO SP. 



Glomerella cingulata (Stonem.) S. and v. S. 



On January 30 a leaf of this plant from the greenhouse, showing an 

 elongated dead area in the center which bore acervuli of Gloeosporium 

 and immature perithecia, was sterilized in the usual manner and 

 placed in a moist chamber. On February 3 many dark spots had 

 appeared on the apparently healthy portions of the leaf. Acervuli 

 soon appeared in abundance, and later, setse were found. On February 

 17 many mature perithecia of Glomerella were also present. Neither 

 form of this fungus appears to have been heretofore reported on this 

 host. 



On February 7 two tube cultures were made by transfer of conidia 

 from the leaf in moist chamber. Acervuli with pinkish masses of 

 conidia soon developed, also chlamydosporelike bodies. No peri- 

 thecia appeared, and subcultures kept until January 23 produced 

 none. The conidia on the leaves varied from 14 to 16.5 by 4.5 to 6.75 p. 

 The ascospores measured from 12 to 24 by 5.5 to 6 p. An ascus and 

 ascospores are shown in Plate II, figures 22 and 22a. No characters 

 could be found either on the host or in the cultures to distinguish 

 this fungus from that occurring upon various other hosts. 



ERIOBOTRYA JAPONICA (THUNB.) LINDL. (LOQUAT). 



Glomerella cingulata (Stonem.) S. and v. S. 



On January 29 an apparently healthy leaf taken from a green- 

 house plant which also showed some spotted leaves was treated as 

 usual and placed in a moist chamber. On February 11 the leaf had 

 turned dark brown and a few scattered acervuli were present. On 

 April 8 acervuli were abundantly scattered over the surface. Setae 

 were sometimes present. No perithecia were found. 



On the same date two spotted leaves from the same plant were 

 placed in moist chamber. On February 12 abundant acervuli were 

 present on these leaves. On February 20 perithecia of Glomerella 

 were also found on the leaves. 



Pure cultures made from acervuli from the leaves in moist chamber 

 produced an abundance of typical acervuli, but no perithecia were 

 ever found. The conidia from the leaves ranged from 12 to 18 by 

 4.5 to 6 p; the ascospores from 15 to 19.5 by 5 to 6 p. Neither stage 

 of this fungus seems to have been described from this host heretofore. 

 Asci and ascospores are shown in Plate I, figures 11 and 11a.
