Hyaloscypha albohyalina?
Ethan Crenson, 17-01-2020 23:49
Hello again,

I found this in a NYC park on very wet, rotted hardwood.  I believe it's Hyaloscypha.  The cups tiny white, glassy and very fragile and fringed with white hairs. Asci are 38-45 x 7µm, IKI+, without croziers (but again, please check my photos to be sure, as I am sometimes wrong).  Spores are 7-9 x 2.5-3, fusiform, hyaline, some with minute guttules. Hairs usually septate, tapering to a rounded end, or with a ball at the end, also sometimes with some exudate encrustations toward the apex, 46-50 x 3-4 (at the base) µm.  Paraphyses cylindric, narrow the tips about 2µm.  I don't know a lot about this genus, so any help would be appreciated.

Thank you,

Ethan

Re : Hyaloscypha albohyalina?
Hi Ethan

couldn't this be softwood? The rather broad hair tips and the yellow resin on them, together with croziers and amyloid ring clearly point Hyaloscypha aureliella.

Re : Hyaloscypha albohyalina?
Zotto,

There are so few conifers in New York that my default position is often hardwood.  In this case I suppose this may be conifer.  When you mention yellow resin, are you looking at the photos of the hairs in water or the one I took in IKI?  The mounts in water are a lot more neutral looking, but maybe you see something that I don't.

Thanks,

Ethan

Re : Hyaloscypha albohyalina?
You are right, it is the IKI photo that mislead me - anyhow the resin of H. aureliella may also be hyaline, I think it is this species. Conifer wood is easily recognized from a look on the cross section.
