Ciliolarina on resin
Juuso Äikäs, 15-11-2021 00:35
On Saturday I found some white discos growing on blackened resin of Picea abies. The fruitbodies appear to stain yellow to reddish upon damage or drying.

The spores measure 6.6 - 10.4 × 2.5 - 3.3 µm. Asci IKI+(bb), with croziers, measuring 43 - 51 × 7 - 8.5 µm. The paraphyses have a long VB that stains violet in IKI. The hairs have inflated tips, and at least some seem to be minutely warty (same with some paraphyses).

I'm fairly sure the genus is Ciliolarina, but further I can't tell.

Dear Juuso,

thanks for your posting in this genus!

I replied yesterday but probably forgot to click "enregistrer"

To my opinion this is C. neglecta, the sporeshape, staining on damiging and the IKI purple reaction of VBs in paraphyses and hairs. C. laetifica has more elongate spores and C. ligniseda has clear fusoid spores with 2 oildrops and asci that are permanent IKI negative.

Best regards,

Stip

Re : Ciliolarina on resin
Thank you for the answer! The spores are maybe a bit on the large side, but otherwise that species would seem to fit.

The elongate spore in the middle left is defenitly already starting to germinate
