Gernot FriebesHi,I'm struggling to find a name for this species.
[Lachnum cf. reynoutriae] Lachnum sp.

Here is another recolt. on Epilobium too with Lachnum reynoutriae.
Macro is same then L. reynoutriar exept the hymenium which is yellow.
Spores 6,7-7,4x1,5-2,1 um with 1guttule at each end.
Asci without croziers, iki+, 35-40x4-5 um.
Paraphyses 70-80x4-5 um, with many guttules, 20-25 um protruding.
Hairs 2-3septate, 70-90x3-4 um with sometimes a slightly widened extremity (l=4-5um)
What do you think about this specie ?

Re:Lachnum sp.
L. brevipilosum even if paraphyses are 20-25 um protruding ?

Re:Lachnum sp.
Hi Stip
VBs were hyaline so it's not that. Unfortunately I haven't made any picture of that.
I don't know what it could be !

Re:Lachnum sp.
Hi Yannick and Stip,
The ''yellowing phenomenon'' that Stip talks about is actually frequent with L. pudicellum but also with other Lachnum species or in other genera such as Crocicreas. The substrate has also partly got the same yellow sulphur colour in that case, which may indicate that the mixed white and yellow specimens are the same species .

Re:Lachnum sp.
Yes, I also think that the yellow colour of the VBs are not a species marker. Therefore I doubt a bit whether the yelow L. morthieri on Phargmites is different from the white L. controversum.
In L. reynoutriae there are no refractive VBs, so I don't know where the yellow pigment is located.
At least we can say that the spore size of this yellow one now better fits L. reynoutriae.
