Trichopeziza on heracleum
Ralph Vandiest, 13-05-2014 21:28
Ralph VandiestHello,

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 ?

Re : Trichopeziza on heracleum
T. autumnalis I created for a specimen in late summer with simple-septate asci.

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.

Hello Zotto,

I will have another look at it tomorrow.

Re : Trichopeziza on heracleum
So Trichopeziza leucophaea has no croziers.
The keys I use are old and have not mentioned the precence of croziers.

Re : Trichopeziza on heracleum
I think there is no public key that uses croziers in Trichopeziza. 

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....

Re : Trichopeziza on heracleum

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 ?

Hello,

Thx for all the reactions. Uploaded picture of asco base and also of the setae who are sometimes swollen at the top (didn't notice thta yesterday)

Re : Trichopeziza on heracleum
Yes, clearly no croziers. So perhaps T. lizonii (in the original, not my previous sense)
