Inermisia fusispora?
William Slosse, 19-12-2019 21:27
William SlosseHello Forum,

today I found in damp Alnusforest a species growing gregariously on remains of leaves lying on the ground. At close proximity there was a lot of donkey dung.
I thought this could be Inermisia fusispora.

Spores: fusiform, hyaline and smooth, containing 2 large oildrops and many smaller drops. 
(21.32-)22.84(-25.05) x (8.15-)8.93(-9.89)um
Asci 8-spored and with croziers, J-
Paraphyses cylindrical and slender. Apically strongly curved. Filled with many tiny yellow oildrops. At the base often forked.
Microscopy in water.

Am I right?

Re : Inermisia fusispora?
In my opion it is Byssonectria (Inermisia) terrestris.

Re : Inermisia fusispora?
Thx, Uwe.
I'm still not sure. It seems dat the spores of fusispora have an average Q of 3.2 and terrestris 2.6.
The spores of my find have a Q of 2.55...
To be continued.
Regards,
William

Re : Inermisia fusispora?
Hi,

the size of fusispora spores should be larger, also the paraphyses of fusispora are normally straight to slightly curved.

A morphological as well as a genetical comparison of terrestris and fusispora you can find in this paper: LINDEMANN, U., VEGA, M. & ALVARADO, P. (2015): Revision der Gattung Kotlabaea: K. deformis, K. delectans und K. benkertii. In: Zeitschrift für Mykologie 81/2, page 384-87

You can download the paper at my Researchgate account.

Best, Uwe

Re : Inermisia fusispora?
Je pense également qu'il s'agit de I. terrestris après consultation de l'article de Uwe Lindeman dans ZfM 2015 81/2 pag 384
