Pale Trichopeziza
Juuso Äikäs, 28-04-2024 13:30
On Friday I found these pale, hairy little discos growing on an old, fallen Chamaenerion anguistifolium stem.

Asci 8-spored, IKI+(bb), no croziers. Paraphyses sublanceolate, many with a few large blobs inside. Hairs very long, septate. Excipulum with globose cells.


Spores:


(7.3) 8.5 - 10.9 (11) × 1.7 - 2 µm
Q = (3.8) 4.4 - 5.9 (6.5) ; N = 10
Me = 9.4 × 1.9 µm ; Qe = 5.1


I'm pretty sure this is a Trichopeziza, but am a bit uncertain about the species. The spores are fairly small, but could this be named T. mollissima (a species complex, I believe)?

Re : Pale Trichopeziza
Good observation with absent croziers? The white form is T. mollissima (earlier I thought I must use T. leucophaea for it). There exists a form with croziers but more often is the H- case. For yellow finds one must use T. limonipilosa and sulphureopilosa nom. prov.

Re : Pale Trichopeziza
Ok, thanks for the info. Yes, this seemed to be clearly without croziers.
