A fellow student working with mosses came up with this lovely Helotiales (?) among Acroporium sp. herbarium specimen from Vietnam.

There are some remnants of hairs clustered into "teeth" (cf. "Pezoloma" or "Echinula"). The paraphyses are just lovely: they are strikingly swollen, kind of "balloon-on-a-stick". Asci relatively small as well as the spores (ca. 6 x 3 um) Spores with septa.

All ideas wellcome. There's not that much material, so I'll make more slides based on comments.

Re : Disco on Bryophyte
Asci are IKI-? Croziers?

The excipulum is also perhaps peculiar? A pity that no living paraphyses are there, because of contents in the swollen tip?

Re : Disco on Bryophyte
I am undecided about the crozier, if yes, then very small. I'll do IKI tomorrow and I'll zoom on the excipulum too. Nothing fresh available. Here's one macro.

Re : Disco on Bryophyte
Perhaps in water the contents of the paraphyses are still visible, remember Seppo's "yellow pigment" of herbarium material which usually disappears in KOH.

Re : Disco on Bryophyte
Some more data:

spores ca. 6 x 2,5; ascus tip strong blue in LUG and MLZ, shape should be noted (is there a name for it?); some structures resembling a crozier, but still not really sure; excipulum even sized textura globosa. Paraphyse contents turn golden yellow in LUG, in water contents hyaline. No other kind of paraphyses, the developing asci are not cylindrical, but tapering.

..and it's all 1000X, the scale in fig. 3 applies in the new photos as well.

Re : Disco on Bryophyte
Only the thin ascus wall reacts at the top! Like in Peziza!
And the paraphyses contain something yellow in the inflated apex, quite surely VBs.
Such VBs occur e.g. in Thelebolus, but that group has inamyloid asci.

Re : Disco on Bryophyte
Yep, the asci look strange to me, I don't connect them to Helotiales. It's reported as common (don't know the exact locality) in its whereabouts and there should be some recent (<1 month old) material coming in to TUR during Spring.

thanks,

Timo
