On a trouvé cet asco sur un bûche dans un ruisseau, Derbyshire, Nord de l'Angleterre, le Juin 23. Il était avec Bulbillomyces farinosus.
We found this asco on a log in a stream, Derbyshire, Northern England, on June 23. It was with Bulbillomyces farinosus. There were 2 sessile fruitbodies, the larger was 3 mm diameter. The texture was gelatinous. The colour was olive-brown. Spores measured were 19-20 x 13-15. Asci were operculate, typically 275 x 20, uniseriate, 8-spored. In iodine reagents they became pale blue or red-brown.
Paraphyses were septate with ends swollen to just over 10 um. In water they showed pale brown contents. In iodine reagents they turned deep red-brown at the ends,
I was unable to find any "hairs", but a squash of the disc edge showed a variety of cells, including round cells about 40 diameter. Because of the gelatinous texture I was unable to make a cross-section of the ascocarp.
From Fungi of Switzerland Vol. 1 I named this as perhaps Pachyella babingtoni, which has been found at least 7 times before in our region. It is however, more olive than red-brown in colour.

Re : Pachyella babingtoni?
Hi Steve looks fine to me; compare with http://www.ascofrance.com/uploads/recolte_file/Adebab0a-0001.pdf (this should zoom to 400% without pixellating). In this micro-habitat keep an eye out for conidia of tiny aero-aquatic fungi - often very complex and beautiful - e.g. http://www.ascofrance.com/search_recolte/3601 .

Re : Pachyella babingtoni?
Merci Chris!
Your cross-sections are very nice!
I've had a few looks at "foam" fungi - the best location was just down the bottom of our road in the mucky Meers Brook, straddling VCs 56 and 63. We used to play in it as kids, and survived.

I'm hoping to do a thorough study of the aquatic hyphomycetes at Longshaw - maybe this autumn. I have a good paper on them in a box in the attic.
Cheers,
Steve
