Apothecia superficial, solitary, or several springing from the 

 same substratum, at first subglobose and closed, expanding and 

 usually becoming vertically elongated on one side when mature, 

 yellow, brown, dark-blue or olivaceous; the excipulum subcoria- 

 ceous, composed of interwoven hyphae which often project from 

 the surface as short, stout, septate, hair-like hyphae, often 

 violet with transmitted light, or when treated with K. O. H.; 

 asci cylindric, or clavate, 8-spored; spores small, hyaline, simple; 

 paraphyses filiform, or in one species lanceolate above. 



Type species, Midotis Lingua Fries. 



This genus corresponds with ScodeUina or Otidea of the 

 operculates on the one hand, and Wynnea and Phillipsia on the 

 other, but differs from both in the inoperculate asci and the 

 relatively minute size of its asci and spores. Saccardo combined 

 Wynnea and Midotis although they are widely separated, the 

 former being an operculate and the latter an inoperculate. 



Rutstroemia Karst. was founded on Peziza bulgarioides Rab. 

 which in the opinion of the writer is a Midotis. Karsten's genus 

 contained several other species not now regarded as congeneric 

 which has resulted in much confusion. We cannot accept 

 White's version of the genus in which the last species mentioned 

 by Karsten is adopted as the type. 



Apothecia dark-blue, violet, or purple, nearly black in 

 mass. 

 Paraphyses with lance-like tips; apothecia large, 



several cm. in diameter. 1. M. irregularis.
