frequently collapsing. Ostiolum papilliform or inconspicuous. Asci 

 cylindrical or clavate-cylindrical, 8-spored, paraphysate. Sporidia

Cooke and Winter make Teichospora a synonym of Strickeria, 

 which latter name seems to have precedence, but we have retained the 

 generic name Teichospora, which Saccardo has adopted in his Sylloge.
