Mollisia sp. ?
Mirek Gryc, 22-06-2022 12:42
Hello everyone
Some time ago I found small mollisia on an unknown grass species.
I have no idea at all.
Spores:
(10.9) 11.2 - 12.3 (12.4) × (2.4) 2.45 - 2.8 (2.9) µm
Q = (3.8) 4.3 - 4.6; N = 6
Me = 11.6 × 2.6 µm; Qe = 4.4

10.86 2.86
11.17 2.45
11.66 2.51
11.16 2.43
12.26 2.83
12.37 2.68
I present the other features in the pictures.
Do you have any ideas?
Regards
Mirek

Re : Mollisia sp. ?
Did you test the KOH reaction?

M. juncina and M. palustris are possibilities.

Re : Mollisia sp. ?
Hi Zotto
Yes! Negative KOH (see photo No. 8)

Re : Mollisia sp. ?
M. juncina was KOH- but in M- palustris we saw both, - and pale or distinctly yellow.

Re : Mollisia sp. ?
Zotto, if you let, I have one more question for you.

Unfortunately, so far I can't decide what genre it fits better.

Some collections on your disk have abundant subiculum. At my collection I was not able to observe the shreds of the Subikulum similar to the presented on your disk.
Is this feature important and can be taken into account during identification ???

Re : Mollisia sp. ?
Do you mean palustris or juncina? In palustris I see some pics with brown anchoring hyphae, but abundant hyphae I cannot see. Such hyphae has every Mollisia. The abundance of them may be a character, but not a very good one,  I think there is much variation.

Whether all finds in these folders are correctly identified is far from sure...

Re : Mollisia sp. ?
Hello,

I reserve the name palustris for the quite pale grey species on grasses with small spores, not exceeding 9 µm or may be 10 µm in single exceptional spores. Also the spores are (nearly) free of oil drops, similar to cinerea ss. str., but with another shape: needle-shaped with one end more acute then the other, while cinerea has spores with rounded ends on both sides.

So I would say juncina, which is more brownish in colour, spores are bigger and oil content is higher. But I'm not sure wether this is not a species complex ....

all the best,
Andreas

Re : Mollisia sp. ?
Hi Andreas
After analyzing literature on them (primarily your descriptions) I got the same impression. In their case, the Internet introduces a lot of confusion. Species with other features are presented under the same name, so that's why I haven't made a decision about the name of the genre. Although my collection is closer to M. juncina, not all features are compatible with this species, at least I have such an impression.
However, since you also think similarly, I will call it Mollisia cf. juncina.
Thank you for the comment and best regards.
