6. The paraphyses are a differentiation of the palisade layer 

 which covers the fruit body at all stages. 



7. In the ascocarp of this species there are present paraphy sis- 

 like structures which arise early in the history of the fruit body. 

 They are non-septate, thick- walled tubes which originate far 

 down in the hypothecium, traverse the hymenium, and discharge 

 a brown, glutinous secretion at their tips. The writer has applied
