a purplish-brown subiculum. The asci are 100-110 x 7-8. The 
brown spores are straight or slightly bent, 10-11 x 5p. The 
ostiola are very remarkable and just as described by Berkeley 
and Broome. The contents of the perithecia may be seen being 
ejected through the pores as short tendrils. I am not aware 
that this species has again been recorded either in this country 
or abroad.

The epidermis was not perceptibly blackened. It is possible that 
D. trivialis (B. and Br.) Sacc. recorded from Batheaston and on 
Cornus (see Massee, in Grevillea xvuI (1889), p. II) may prove 
identical.

Von Hoéhnel in Ann. Myc. xvi (1918), p. 122, definitely regards 
this species as synonymous with A. rhenanum (Fuck.) Sacc. 
Schroeter in Krypt-Fl. Schles. 11. 2, p. 434, had suspected this. 
Winter in Rabenhorst’s Krypt-Fl. 11. p. 760, had described the 
spores as inaequilateral and bean-shaped, but this seems an 
error or exceptional and neither Schroeter nor von Ho6hnel 
mention it. The spores in my specimen were quite straight, 
broad and oblong, rather abruptly attenuate towards the ends, 
more towards the lower end and with the upper provided with 
a small obtuse hyaline knob. No hyaline envelope was evident 
all round but the knob is very persistent. It was absent however 
in some ejected spores. The valsiform nature of the pseudo- 
stromata is very evident. The upper surface of the cortex is 
blackened but no circumscribing black line was seen. It is re- 
corded on Acer and Fagus by Winter, on Fagus by Schroeter 
and on Carpinus by von Hohnel. My specimens were on oak, 
near Bassenthwaite, Cumberland, Sept. 1922.
