Hab. in spatha emortua Phœnicis dactyli- 

 ferae in horto botanico Napoli (Cesati). Sphœ- 

 rellam ill. Cesati certe vidit, ego autem Phomam 

 tantum.

29. Dothiorella latitans (Fr.) Sacc. Syll. 111, p. 241. 



— Hue videtur spectare, tamquam pusio, forma 

 illa inevoluta, sterilis, subsuperfleialis, densius- 

 cule gregaria, Phomam minutam referens, quae 

 nomine Melampsorœ punctiformis Mont, exlatin 

 Desm. PI. crypt. ex. n. 40 [in Herb. Brux.] et 

 nomine Phacidii Vaccinii in Moug. Stirp. Vog. 

 n. 1180, nam cum vera et evoluta Dothiorella 

 latitante mixta observatur in Lib. Ard. n. 47. A 

 Melampsora typo, ad quem referebatur a cl. Mon- 

 tagne, specimina a me visa longe abhorrent.
