Ellisiella caudata Sacc. 

 West of Albany, on dead leaves of S o r g h a s t r u m nutans 

 (L.) Nash. H. D. House, October 15, 1923. The chief character 

 upon which Ellisiella rests is that the spores are attenuated into a 

 base or pedicle, a character which this collection abundantly con- 

 firms. Saccardo's description of this genus and his remark on the 

 type species, " deorsum (an quandoque apice ?)" shows that he held 

 the view that the spores might possibly be attenuated upwards, which 

 is not the case.
