Tiny black roughened spheroid asco

Ethan Crenson, 28-02-2017 21:11

In Bronx, New York City. Tiny (.5 - 1mm) on decorticated hardwood branch. Roughened spheroid stromata. The spores are large, hyaline and up to 3-septate, sometimes with the center two cells slightly more swollen and guttulate than the end cells. Asci with 8 spores, IKI-, 64 - 68um by 12.8 - 14.4um. Spores measure 33 - 35um by 3 - 5um.

Re : Tiny black roughened spheroid asco

Very glad to see the technical issues are resolved for this site. I was toying with the idea that this might be Bertia moriformis, but I think the spores have too many septations. Is there anyone who might have some insight? Thanks.

Bertia moriformis. It is a weed in many parts of the USA.

Re : Tiny black roughened spheroid asco

Thanks Andrew! I revisited this collection today and found spores that fit much more comfortably with Bertia moriformis var. moriformis, so I'm pretty comfortable calling it that. The photos I added show the specimen in cotton blue and Meltzer's. They appear to be most frequently 1-septate. 33.5-48?m by 4.5-5?m
