Hello,

Found by Laurens van der Linde, March 2024 on solidago.

Is this Anthostomella tomicoides?

I used the key (1-2-17-22-23) in "Francis S.M. (1975). Anthostomella Sacc. (part I). Mycol. Pap. 139: 1-79"

- spores two celled

- spores 14-19 x 5-8 µm, strongly inequilateral

Greetings, Riet

Hi Riet,
yes, very likely A. tomicoides. If so, you should find a short germ slit on the dorsal side, often best seen in KOH or Melzer's reagent.
Cheers,
Jacques.

Hi Jacques,
Thank you very much for your help!
I will try to find the germ slit.

Re : Anthostomella tomicoides? on solidago
Very difficult to get the spores into the right position. Made several attempts in KOH 3% and in Melzer's but without success.
Only one spore with something that could be the germ slit

Re : Anthostomella tomicoides? on solidago
yes, typical.
Hunting germ slits may proove challenging, especially when spores preferably lay in side view because they are laterally flattened. Otherwise, it would be too easy!
Cheers,
Jacques
