TUBERCULARIACEAE 



219 



Family 87. TUBERCULARIACEAE 



Hyphae compacted into a globose, pulvinate, discoid or verruciform body or 

 sporodochium; sporodochia typically sessile, erumpent or superficial, byssoid, waxy, 

 fleshy or subgelatinous, hj'aline, bright-colored, or dark to black; conidiophores 

 typically long and ramose, sometimes short and simple or rarely obsolete, usually 

 not arising from a cellular stroma-like base; conidia various, lacking in one anomal- 

 ous group, as are the conidiophores also. 



This family is more or less readily distinguished from the Moniliaceae and 

 Dematiaceae by the presence of a sporodochium, and from the Stilbaceae by the 

 practically universal sessile habit. On the other hand, there is no satisfactory dis- 

 tinction between it and the Melanconiaceae, as the two groups are at present con- 

 stituted, and genera with short simple conidiophores must be sought in both. These 

 are thought to belong properly in the Melanconiaceae, but this transfer has not 

 been made, owing to the number of genera concerned and the inadequacy of many 

 of the descriptions. Properly limited, the Tuberculariaceae comprise only those 

 genera with long and typically branched conidophores without a basal stroma. 

 The distinction drawn by Hoehnel with respect to the insertion of the spore-body 

 in the matrix, i. e., persistently innate in the one and erumpent-superficial in the 

 other, may possess some validity, but it is not a practicable criterion. 



An anomalous group without conidiophores and conidia is referred to this family 

 by virtue of the possession of a sporodochium.
