Collection location: World’s End, Boston Harbor Islands, Boston, Massachusetts, USA [Click for map]
Part of the fungal survey of the Boston Harbor Islands, organized by Danny Haelewaters. Specimen to be deposited at the Farlow Herbarium, Harvard.
Scale bars: a, 3 mm; b & c, 1 mm; d–g, 10 µm.
The anamorph is present in the deep clefts between perithecia, and is clearly a Geniculosporium, with typically anamorphic characteristics of subfamily Xylarioidea (which also includes Xylaria; the other subfamily, Hypoxyloidea, includes Hypoxylon and Annulohypoxylon). The small, reniform ascospores are distinctive, if non-descript.
I’m not 100% certain of this ID, but I’m not really sure what else it could be. Open to other ideas/suggestions.

out of curiosity, what do you use to create these elegant scalebar-ed plates?
