Hi to everybody.Can you give me any suggestions ab
Stomata very thin, uniform black with fairly evident conical ostioles, mostly multiperitheciate but numbers vary greatly. No white or carbonous tissue below perithecia, these appro. 200 µm.
Asci, 8-spored, I+ blue, rather low. Spores medium brown 8,0-9,9 (av. 8,6) x 3,7-4,1 (av. 3,9) µm, n=6, without appendages; germ slit faint but full length and straight.
cheers
I think I know this species - I had a collection from last year on Chusquea culeou culms, South UK. Like you, I couldn't easily identify it, so I PCR-tested it and got an ITS barcode (direct from perithecia).
It didn't tell me much, it was quite far from everything. Closest match was a collection of Lopadostoma cf. polynesium on Amelanchier by Alain Gardiennet - But only with 85% similarity.
Adding to the ambiguity, I read that L. polynesium isn't really a true Lopadostoma.
I know that some users of Ascofrance have done studies on bambusicolous Xylariaceae so I wonder whether anyone else knows more?
Cheers,
Nick
