Adelphella babingtonii - lacking much brown pigment
Ethan Crenson, 20-08-2025 19:04
Hello,

This asco was found on the same wood as my previous post (Hymenoscypha varicosporoides) which was lying in mud and water in a New York park.  The wood was probably hardwood. There was Fagus, Quercus and Tsuga nearby. 

They are gelatinous and pulvinate. When found they were off-white, the largest about 1cm. 

Spores are thick walled, have two large guttules. They measure:

19.4-20.3 x 11-12.8µm
Me: 19.8 x 12.0µm
Q: 1.56-1.76
Qe: 1.64
N=14

The asci are IKI+ along nearly the entire length.  

Paraphyses are enlarged at the ends, reaching about 4µm. They contain oil content, however, the typical brown pigment is mostly absent.  I left it in the refrigerator to mature a bit and the apothecia turned a tan color and the paraphyses became slightly yellow-brown. 

Excipular elements have a textura globulosa and some cells have finger-like protrusions.

Maybe this lack of pigment is typical of immature specimens?  Could this be something else?

No doubt, an Adelphella species

Re : Adelphella babingtonii - lacking much brown pigment
Hi Nicolas.  Thanks for the reply.  But isn't Adelphella a monotypic genus?

One species described, but probably more, especially in USA. See attached ITS tree.

I had a feeling!  I will sequence this collection to see where it fits in.  Thank you for sharing that tree. By the way, I was on the 2023 Korf Foray where PP342557 was collected.
