Order 21. MELANCONIALES 



Family 84. MELANCONIACEAE 



Pycnidia lacking, represented by a stroma-like stratum; strata typically bear- 

 ing simple or ramose basidia upon which the conidia arise, forming acervuli or 

 masses, which are immersed or erumpent, black, gray or light-colored, waxy, 

 horny or gelatinous; conidia various. 



The spore-body of this family closely approaches the discoid form frequent 

 in the Discellaceae on the one hand and the sporodochium of the Tuberculariaceae 

 on the other. Hoehnel places the latter and Melanconiaceae in the same group, 

 Gymnostromaceae, distinguishing the one as innate-erumpent or superficial and 

 the other as persistently innate (1923:309), but this distinction appears to be 

 neither valid nor practicable. While the superficial resemblance is often great, the 

 sporodochium proper is to be regarded as a compacting of hyphae and conidiophores 

 rather than a new development from a reduced fruit-body with short or obsolescent 



basidia.
