Journal 1 in which several parasitic fungi of Permo-Carboniferous 
Age are described. One of these which is found on the fronds of 
Alethopteris Aquilina, has been considered by Magnus’ to agree so 
closely with the recent genus Urophlyctis that he has suggested for 
it the name of Urophlyctitcs Oliverianus. After referring to the 
various papers by Magnus and others on this interesting genus, I 
have come to the conclusion that a possible explanation of the 
structures observed in the Stigmarian rootlet is afforded by the 
supposition that it had been attacked by a fungus of the Urophlyctis 
type. Nor is this assumption hazardous now that we have Magnus’ 
authority for the existence of a Urophlyctites at the Coal-Measure 
period.

the dark wood elements at the top and a large space in the position of
