Psilopezia?
Carmel Sammut, 09-07-2015 20:04
Small specimens (5-7mm) in diameter on twigs in humid area. Collected in December.
Underside shows whitish hyphae (subiculum?)

Asci J-ve & IKI-ve - not sure if pleurorhynchus
Paraphyses septate and splitting, without inflation or colour deposits.
Spores - a few with 2 guttules but mostly without, perhaps immature.
22.9 - 25.7 x 14.2 - 16.7µm Q = 1.4 - 1.8 Mean = 24.1 x 15.3 µm
Subhymenium appears gelatinous (but I am not sure) - textura intricata
Medullary excipulum & ectal both appear made up of textura intricata with elongated transparent hyphae.

I can't key this out using Häffner's key for Psilopezia, any suggestions? Is the genus correct?

Hi Carmel
I think it is a Kompsoscypha.
Cheers,
Raúl

Re : Psilopezia?
Thanks Raúl.

I had no clue about this genus. There is an entry for Kompsoscypha cf. chudei on this site and it does look similar.
