“(Von Coleroa durch 1 zellige Sporen und glattes Gehause, 
sowie durch ganz anders geformte Schlauche, von Trichosphseria 
durch hautige glatte Perithecien vollig verschieden. Wurde zu 
Ehren des trefflichen schwedischen Pilzforschers Vestergren be- 
nannt. Scortechinia Sacc. ist nahe verwandt, besitzt aber ein 
‘subiculum ubique spinulis acute dentatis exaspertum.’ Pilgeri- 
ella Hennings [Hedwegia XXXIX. p. 137] hat krustiges Mycel, 
perithecia papillato-ostiolata, asci clavati.)“ [Sec. Sacc. et Syd.

“Receptacle consisting of two superposed cells, the lower 
sometimes apparently obliterated or indistinguishable from the 
foot, the upper bearing a single perithecium and an antheridial 
appendage. Appendage consisting of six superposed cells, the 
basal cell closely associated with the receptacle and the stalk-cell of 
the perithecium; the terminal-cell bearing a spine-like process and 
becoming converted into a simple antheridium, the subterminal¬ 
cell cutting off a cell laterally which becomes an antheridium, the 
remaining cells sterile. Perithecium stalked, normal in structure.
