Chaetosphaerella ?
Ethan Crenson, 11-04-2019 06:53
From New York City last weekend, growing on an old Pyrenomycete (Eutypa, probably) I think this is Chaetosphaerella.  The small clusters of black fruiting bodies seem somewhat flattened at the apex.  They are seated in a dense brown subiculum.  I did not see any asci in any of my mounts.  Spores are 3-septate, brown with hyaline end cells and guttules in the two inner cells, usually curved. They measured 24-29 x 6-7µm.  I'm uncertain if I saw any conidia-- in the final photo there is a bowling-pin shaped brown cell that has two guttules. 

Could this be C. fusca or C. phaeostroma?  Does the difference come down to the conidia?

Thank you in advance for your help.

Re : Chaetosphaerella ?
This is C. fusca.  The difference is whether or not the ascomata become collabent and the size of the ascospores (longer in C. phaeostroma).
