The hairs are septate, tapering, smooth or minutely punctate. Paraphyses extend well beyond the asci and taper to an almost acute point. They appear to contain oil droplets.

Asci are 61-72 x 6-7µm, IKI+, croziers+ (please correct me if I am wrong).

Spores are long with acute ends, 15-43 x 2-4µm. The spores might range somewhat longer than my measurements—in looking back over my photos I see what may be broken spores that I ignored because I thought they were broken paraphyses. (see the last photo)

I will probably have to return to the place of collection and look again to get more details about the hairs and the true spore measurements. But maybe someone can point me in the right direction with the limited information I have presented here?

Thanks,
Ethan

Re : Lachnellula with long spores - L. pseudofarinacea L. ellisiana?

This is superb, yes, it is obviously L. ellisiana! It's the first time I see photos of this species. Mystudies relied on the type and a sample from 1978.

Croziers are clearly present, with a small perforation as typical in Lachnellula.

It would be great to gather more apothecia. Please take care also of living asci which should be greater than those you indicated which are narrower than the dead ones I measured.

Did you use a constant zoom in your photos? Coolpix under maximum zoom? It would be valuable to have a scale for them.

Also I would be glad to note the colletcion data as I have a long-lasting paper in preparation about this and some other Lachnellulas.

Not to forget that to say this species is so far unsequenced.

Hello,
I am happy to offer ITS sequencing for this species. If you are interested, please drop me a message.

Cheers,
