Ad folia viva Brunellae sp. in insula Un-

In studying the herbarium of E. Rostrup 

 (in the Copenhagen Herbarium) cand. pharm. J. Lind 

 has come across the above named fungus. On the 

 label Rostrup has written Linospora Brunellae 

 sp. n., which name however has never been published. 

 Mr. Lind has referred the species to Linospora Fig. 6. Ophiobolus 

 Brunellae Ell. et Ev. and cited as synonym to it Rostrupii sp. n.

material we have found that this fungus moreover, 



having the spores twice as long as the above species, cannot at all belong 

 to either of the two genera. As well the form of the asci and the spores 

 as the presence of paraphyses refer the fungus to the genus Ophiobolus.
