MOLLISIACEAE 133 



Family 53. MOLLISIACEAE 



Rchm 503 

 Apothecia innate-erumpent, or superficial from the first, mostly scutellate to 

 discoid, opening circularly, typically smooth, mostly fleshy-waxy, disk dark-gray 

 to bright-colored, frequently on a subicle; hypothecium thin for the most part, 

 epithecium obsolescent, cxciple characteristically parcnchymic and brown; asci 

 mostly cylindric and 8-sporcd, paraphyses filiform or lance-pointed; spores typically 

 hyaline. 



This family is closely related to both Patellariaceae and Helotiaceae, as well 

 as the smaller forms of the Pezizaceae. As a rule, it may be readily distinguished 

 from all of these by the brown parenchymic exciple and the poorly developed hypo- 

 thecium.
