Dear Forum,On decorticated wood of Castanea,I foun
I found this species on heracleum. Size up to 2mm, with yellow hairs? Spores 9/18x1,5/2µm. Asci iKI red 60/69x4/5. Spores without guttules and aseptate
Could this be Trichopeziza autumnalis?
regards,
Ralph
Hi Ralph,
I cannot find any mention of T. autumnalis.
Did you consider T. mollissima for your find ?
Amitiés
Michel
Could you look for the corziers?
T. mollissima is a problem. It was wrongly adopted by me, as it should be restricted to purely white populations. Maybe there is no name presently available for the yellow one with croziers.
I will have another look at it tomorrow.
Regards
The keys I use are old and have not mentioned the precence of croziers.

I am not sure what T. leucophaea is, perhaps a name to adopt for one of the yellow ones (maybe the one with croziers, I don't know). But Marketa suggested a name (sulphureopilosa) for what I thought to be mollissima (yellow, with croziers). Hope her study will be finished some time.
And she put the type of lizonii as identical with my autumnalis (yellow without croziers). Then T. lizonii in my sense became a fungus without name....
Zotto
Hi Zotto,
I then discover a lot of changes in this group, also with the IKI reaction . I used to consider mollissima with a red one ..
The now unnamed lizonii is the one with the special spore guttulation as presented here ?
