Xylaria aff. comosa sensu Laessoe

Looking more closely at Laessoe 1999 treatment of the group I can see that this does belong here for the time being.

Distinct from X. comosa

I believe this has to be either very loosely included in the comosa group or it is something completely different. The stromata are more globose and the stipes lack the pubescent hairs of comosa. I’ll check to see if I have spores.
