Hulda Caroline HolteHello,I collected this species growing on a dead b
Using Declerq's Hilberina key (published in Sterbeeckia 2013) it could be Hilberina subcaudata (a species only known from Belgium). Spore length (41-49,5 um; 3-septate spores) varies more than the two specimens examined by Declerq (44-48,5 um). (This species is not coverd by Miller et al. 2014.)
However, on one of the shown images (#307; 2nd) the ostiole looks somewhat sulcate, although not as prominent as shown in the drawing of a similar species, H. moseri in Hilber (1983). [This feature is not mentioned by Miller et al. 2014 who have examined the type material.] Moreover my find lacks the strongly tuberculate outer wall of H. moseri. Spore width (4,5-5,5 um) is somewhat less than given for H. subcaudata (5-6 um) but wider than in L. moseri (4-4,5 um).
Any comments on the identification of this collection would be appreciated.

As I have recently done for others, I am happy to sequence your specimen if you could send me 15-20 ascomata in good condition. I have built an excellent DNA database of taxa in the Helminthosphaeriaceae.
Cheers,
Andy
Thank you very much for your offer to sequence the collection. Unfortunately the number of ascomata present is not more than a few. Moreover, they are scattered over a heavy piece of (hardly rotten) wood. I will revisit the collection site soon, hopefully it is possible to collect more material. I will keep you informed by email.
Cheers, EDuard
