I 3^ MICROMYCETES ITALICI 



nuata clavati. Paraphyses filiformes. Sporidia elongato-oblonga quinque sex- 

 locularia, articulis turgescenlibus ullimo angusliore et longiore, hyalino- 

 lutescenlia. 



Sphaeriae platyslomae italicae ad hodiernam usque diem mihi cognilae 

 sequentes sunt.

Memoratis speciebus ob sporidia tj-ansvei-se septata, plus minusve olivaceo- 

 fuscescentia , nonnuUae e sectionibus oblectarum, caespitosaruin, confluen- 

 tium, pertusarum, denudatai-uin , subteclarum, obturatarumque accedunt. 

 Sporidia in nonnullis, ex. gr. in Sphaeria Pulvere-pjrio , obducenle, Ver- 

 nicaria inullo qiiam in relicjuis minora sunt, sed ad dilTerentias e dimen- 

 sioned colore, locidonim numero in generis huiusce emendatione vix at- 

 tendendum est; habemus enim et inter Platyslomas species quae sporidiis 

 duplo, triplo, quadruplovc minoribus tjuam in Sphaeria Balsamiana do- 

 nantur. P\Tenionmi compazine vero, quae prae crescendi uiodo vel dehi- 

 scendi ratione in j^radatione chai'acterum , pone sporidia, primum oblinei'e 

 debet locum, Sphaerias italicas sporidiis pluriloculaiibus olivaceo-fuscescen- 

 tibus donatas. in duas saltern sectiones interim sequente pacto distingue.
