The epidermis is ruptured and ]»ustulil'nrni-elevated, and when 

 this is stripped otV. the clusters of pcrithecia are exposed, seated on the

 the epidermis is peeled off, the perithecia either adhere to it or remain 

 attached to the surface of the iimor hark, in which respect this dilVers 

 from Cryptosp/un'ia secreta, C. ^ E., in which the perithecia always 

 adhere to the epidermis. This latter sjiecies also has longer, distinctly 

 clavate asci, with a long, slendei' l)ase, and longei' sjioiidia. and is. we 

 believe, sjiecifically distinct from the sj»ecies on alder, though nuich 

 reseml)ling it.
