Eutypa aurantiicola Speg. Fungi Guaran. II, nr. 65. 



Our specimens are quite in accordance with Spegazzini's detailed 

 description, the perithecia only being on an average somewhat larger. 

 This deviation surely arises from the different substrata (Spegazzinis 

 specimens were found upon naked roots of Citrus Aurantium). Eutypa 

 comosa Speg. is closely related to this species and E. micromeria (Mont.) 

 Sacc. seems after the description hardly to be different. — On stumps 

 of wood.

 Fung. Ill, t. 394. 



By this variety that also occurs in Denmark the stroma forms no 

 extended coherent crust but is as broken into small separated stumps. 

 In some elder specimens the yellowish-green colour otherwise characteristic 

 for the interior of the fungus had gone through to the surface so far 

 that the stroma had also outwardly a dirty-green tinge. — On stumps 

 of wood.

 limit of the genus Hypoxylon.
