Tympanis. 



Several of the species have a conidial form of fructification similar 

 to the conidial forms of the species of Dermatea and Cenangium; thus 



Tympanis pinastri corresponds to Micropera pinastri (see Tul. Carp. 



IIP"-) 



Catinula is very closely connected with Dothichiza. 

 Another part of the species is related to Sphaeropsideae of the type 

 of Dothiorella viz : 



Tympanis conspersa — Dothiorella stromatica (see v. Hehnel 06 a ^^^). 

 — alnea — — inversa (see Hehnel 06 a "^ &. Jaap 



08^').
