The darkred, spherical, but soon crateriformly depressed perithecia 
are gathered in clusters which break through the periderm. Asci clavate 
70—90*10 u, as a rule with numerous small (5—7X1—1.5 u), cylindrical, 
curved, clear sporidia; but other asci occur, with 8 2-celled clear asco- 
spores, lanceolate, with no constriction at the septum, straight or slightly 
curved 10—14X2.5—3.5 u, often with a cylindrical appendage 5—6X1 u, 
which is obstricted and gradually forms the above-mentioned sporidia.
