I found a lichenicolous fungi growing on Sarcogyne regularis. I think it is Acaroconium punctiforme (Kocourkova, J. & Hawksworth, D. L.;2008).
The Conidiomata pycnidia are arising on the apothecial discs and are 60-75 um in diameter, I did my best to make this visible on some photo's. The conidia are non-septate, somewhat irregular broadly ellipsoid, slightly pale brown with 1 or 2 guttules, measuring 5.5 - 6.8 x 3.2 - 4.0 um (n=8).
Can anyone confirm this is Acaroconium punctiforme?
Kind regards,
Niek Schrier
Try to get a Foto with CC (conidiogenous cells ) and conidiogenous unit (Conidium still attached on CC) sometimes possible also in squash preparation. (Success rises also with squashing a hand cut section, Not only squashing a whole conidium). You need to do that also in Lichenconium or some Lichenodiplis!
This gheterogenetic group of phaeosporous coelomycetes can be quite challenging!
;--)
All the best
