This species which has very much the appearance of species of Corrthromf is most u< arly related 
l(» L. forficulata and L. fism. In the material obtained in the Berlin Museum from T. brcvicoOu, th< 
individuals are far larger than the original types, almost twice as large, but there seems no doubt i to the 
identity of the two, although the form of the perithecium ami its tip is somewhat different in the Berlin 
material. On T. subloevis a single mature individual was found in which the total length . a nearly 
800 jv, the perithecium 265 X 65 /*, its neck 150 /v, the receptacle but slightly suffused, ov» r 325 (i ta( 
and without maculation. The appendages are, however, the same and the form is undoubtedly refelaW 
to the present species.
