Lasionectria ?
Unai Fernandes, 08-06-2021 00:09
Collect these specimens on dead wood. The environment where I found them predominated Quercus rubra and there were also some specimens more distant from Fagus sylvatica but of less constancy.
The samples have matched me with Lasionectria, at least it seems to me but after having looked at several keys I have not square with any species. If anyone could help me, I'd be grateful.

-Perithecia: globose and hairy. At first light orange, then reddish and dark brown. KOH-
-Ascospores: Four guttules with a septa and striates. Measurements of 6-9. 5 x 2-3 µm .
-Hairs: 30-85 x 2-4 µm. With a septa on some.


Any help welcome is. Thank you very much

Re : Lasionectria ?
Hi Unai,
Are you sure the ascospores are striated?

Your specimen looks like Lasionectriopsis germanica but the ascospores of this species are warty.

Re : Lasionectria ?
Hello Christian


Yes, the spores are striated. I haven't seen any warty characters. At least with IKI they only look striated.
I've been looking at Lasionectriopsis germanica, which actually matched very well and it looks like you told me, but seeing that the spores were warty I discard it.

Thank you.

Re : Lasionectria ?
Hi Christian


Do you have any suggestions for this collection? or look at more characters?


Thank you
