Lachnellula ??

Hi,

I found this beautiful and tiny ascomycete on Phytolacca americana.
It remember me some species of the genus Lachnellula or Capitotricha.. but it doesn't fit.
The measurements of spores ( spored ) are 25-31 x 4-4.8, whitout septa,
but some times inside the ascus they have one or three septa ( see pics ).
Ascus measurements are 85-95 x 10 µm.
The reaction hemiamiloid is positive
Any information will be welcome
Thanks.

Re : Lachnellula ??
<les spores par leur taille et leur forme font penser à Lachnellula splendens mais le support serait étonnant.

Re : Lachnellula ??
Hello,

Lachnellula is supposed to grow on conifers only, so this could be another genus. How do the paraphyses look like (live in water)? Do you have a photo of the hairs? Are they incrusted or smooth - and If incrusted, then on their whole length or is the apex smooth?

Ah, this one on Phytolacca! I have it in Hegermila, but with a little doubt. Strange enough the other collection on Phytolacca has distinctly shorter, always 1-celled spores and concurs herein with samples on Urtica and Humulus.

The Phytolacca sample was sequenced and falls not far from Trichopeziza sulphurea.

Re : Lachnellula ??
Hi,

I send paraphyses and hairs pics.
Thanks for your responses.

Re : Lachnellula ??
Good, the last pic shows paraphyses too?

Ivana agreed to send also this sample for sequencing.
