ciopsis, and adopts the latter name for the genus. He incor- 

 porates it in the Calicieae treating this group as a subdivision of 

 the Patellariaceae of the true discomycetes. He states that while 

 it is apparently true that the majority of the Calicieae possess a 

 more or less well developed lichen thallus, in certain species this 

 has not been demonstrated and seems to be absent. These latter 

 species, therefore, are treated as a group of the true fungi. 

 Seven genera, Calicium, Caliciopsis, Coniocybe, Sphinctrina, 

 Cyphelium, Acolium, and Stenocybe are included by him in the 

 true discomycetes. It is evident that he is in error in incor- 

 porating Caliciopsis among these forms. Although the stipitate 

 character of the fruit-body furnishes a point of similarity be- 

 tween Caliciopsis, Calicium, Stenocybe^ Cyphelium, and Conio- 

 cybe, there exist important points of difference. The fruit-body 

 of Caliciopsis is very certainly a perithelium, while in at least 

 some of the other genera described by Rehm, it is just as surely 

 an apothecium. The examination of Rehm's figures, and of 

 such material as has been available, leads the writer to believe 

 that with the exception of Caliciopsis, the other genera included 

 here by Rehm are as stated by him, discomycetous in character. 

 Certainly in the light of our present knowledge there is no reason 

 for regarding them as closely related to the Coryneliaceae.
