Small spored Pulvinula?
Tyler Bailey, 20-06-2022 18:50
I found this small cup fruiting on charred wood in a firepit that I could use some help with. NE US. Spores seemed small for Pulvinula but it could have been immature I couldn't get many to drop onto a slide.

 

Apothecia 1-3 mm On burnt wood in a campsite fireplace. Paraphysis hooked, mostly unforked very little keratinoid pigmintation, IKI-, Spores single large guttule: (7.1) 7.5-8.6 (9.2) x (6.8) 7.2-8.6 (*9.4)

Asci 147x10.6

Hi Tyler
Please, compare with Pulvinula archeri.

Re : Small spored Pulvinula?
Wow that was fast! thank you.

Using Pfister's monograph that was one had looked most promising, the only thing that didn't match besides the spore size was the paraphyses since so few were branched and there was almost no pigment in them (but widthwise they matched).

Re : Small spored Pulvinula?
I attach some descriptions by Huhtinen and Rifai. As you will see, the variability of some characters seems to be large.

Re : Small spored Pulvinula?
That answers that pretty thoroughly, thanks for the descriptions as well.

Re : Small spored Pulvinula?
I agree with Enrique. P. carbonaria, another carbonicolous species, has larger ascospores.
