Orbilia...
Ethan Crenson, 22-10-2025 06:43
Hi all,

I'm having some difficulty with this Orbilia. The apothecia are orange and on hardwood which was on the ground. Margin is smooth.

Asci 25-33 x 4-5µm

Spores are elongated, fusoid, mostly straight but infrequently curved. 

8.0-13.2 x 1.2-1.6µm
Me: 10.4 x 1.4µm. 

Spore bodies sometimes a short line, sometimes longer, occasionally with an enlargement at the end. Spore body length 1.4-2.9µm


Paraphyses clavate, almost capitate at the ends and coated with exudate (which I found stains pink in Congo red.) 

I would be very grateful for any assitance.

Ethan

Re : Orbilia...
Hi Ethan

Although on the ground this is a member of subgenus Hemiorbilia, which are al drought-tolerant.

It must belong in the complex of O. vinosa. From typical O. vinosa it differs in too small, especially narrow spores. There is still much to explore, but these potentially different taxa can hardly be identified without DNA. Surely a sequence would be clarifying in this case, if you have enough apothecia.

Re : Orbilia...
Thank you!  I had a moment when I thought it might be O. vinosa.  I will attempt to sequence this and I will share it with you if I am successful.
