CORRIGENDA. 
Hendersonia typhoidearum, Desm., on leaves of Luzula alhida, 
in my copy of Thumen's Fungi Austriaci, No. 785, is Bphcerella 
Luzuloe, C. Asci clavato- cylindrical, sporidia biseriate, hyaline, 
cylindrical, quadrinucleate, then uniseptate. 
Hendersonia Cynoshati, Thumen, Fungi Austriaci, No. 1061 
in my copy, is Exosporium fructicola, Sacc. 
Hendersonia fusarioides, Sacc., Fungi Yeneti, No. 998, has 
distinct and decided asci in my specimens, and is, therefore, a 
Sphceria.
