White apothecia on Pseudotsuga
Enrique Rubio, 19-02-2021 20:07
Enrique RubioThese small, white, gregarious, broadly sessile apothecia, 0.2-0.3 mm in diameter, with glabrous margins, grew among algae and liverworts on corticated wood of Pseudotsuga menziesii near the sea.
The asci are ventricose, slightly dextrinoid in IKI, with croziers and a broad, very bluish apical apparatus in IKI, and contain eight spores already septate even inside the asci. The paraphyses are moniliform near the apex and the marginal hairs are similar and closely agglutinated.
It doesn't look like a Hyaloscypha, but I couldn't say to which genus it might belong, perhaps it could be an ascolichen?

Many thanks again

Re : White apothecia on Pseudotsuga
Yes, it is an ascolichen. Dimerella pineti or so, now Coenogonium.

The entire asci are reactive, I see a faint reddish but after KOH this should react blue. The spore surface probably turns lilac in CRB.

Typical are the paraphyses with dense septation above.

Thanks a lot, Zotto.
It seems to match well with what you say.
