Family 43. BULGARIACEAE 



Rehm 444 



Apothecia usually superficial from the first, more rarely innate-erumpent, cupu- 

 late to discoid, opening circularly, typically smooth, gelatinous-waxy or gelatinous- 

 fleshy, horn-like when dry, frequently stalked, separate to cespitose; hypothecium 

 gelatinous, thick, epithecium sometimes lacking; asci regularly cylindric and 8-spored, 

 paraphyses and spores various. 



The gelatinous texture of the apothecium distinguishes this family more or less 

 readily from all others of the order, though a few genera approach the MoUisiaceae 

 and Pezizaceae closely. The exciple is more frequently lost in gelatinous forms, 

 apparently because of a lessened need of protection. All such genera are assembled 

 in the Agyriaceae, but those with gelatinous apothecia are also keyed here for con- 

 venience.
