White oddity

I found these on a juncus-like grass. They are about 0,5-0,7 mm high and 0,2-0,4 mm wide. The base of stipe is brown.

Re:White oddity
This showed some facilities new to me in microscope.
I've never seen such paraphyses or hairs- meaning so big droplets.
The spores are 6-12x1-2, asci 33-40x4-5.
Lanceolate paraphyses are 4-5 micrometers wide and exceed the asci about 10-15 micrometers and have lots of droplets.
Hairs are 35-40x3-5 and they have droplets, too. Except at the stipe, where they are smaller, but can branch.
Strange, actually I have no idea even of the genus...

Re:White oddity
Its a Lachnum (Dasyscyphus) species, probably L. pudicellum

Re:White oddity
Yes, I agree. The hairs are surely warted. The droplets inside and in the paraphyses are VBs (vacuolar bodies), they are responsible for the colour change to red-brown in the dead state. Such a fungus may look deep brown when dry. If you add KOH these droplets disappear.

Re:White oddity
Hello,

thanks. One of the synonyms seems to be L. tenuissimum and I've allready found that.
With another microscope things seems different ;)
