How about S scutellata?

According to T.Schumacher (1990) S.scutellata has ascospores with warts with height of 0.5...0.9 um, clearly visible in light microscope. Spores of my Scutellinia sp. visible as almost smooth with 100x oil lens in Melzers reagent and in lactic CB. Ornamentation visible only in CB as pattern on spore surface, but not as relief on spore periphery. Warts, that are visible as relief, have maximum height of 0.2...0.3 um are very rare, hard to find, and may be also artefacts. i'm not sure that they are true warts.
If this (almost smooth mature spores with ornamentation visible as pattern, but not as relief) in conjunction with small ascomata is normal for S.scutellata, this may be acceptable version.

There are two new microphotos (in Melzer's). I previously did not pay attention to this, but immature spores have a clearly visible ornamentation, warts with height up to 0.7 um, that disappears on mature spores.

The sculpturing often changes when spores are ejected. Sometimes smaller sometimes greater so mature spores should always be used. S crinita is described as having minute sculpturing.

Thank You. S crinita was my first version. I was later confused with some microphotos of S.crinita ornamentation, but these photos was mixed up. I reviewed Schumachers's description and drawings, and S. crinita seems to be almost suitable. Only with a minor incongruities - according to Schumacher S.crinita has simple septate paraphyses, and i see moniliform paraphyses in my species, and the spore ornamentation of my species looks lower than in the Schumacher's description (mainly invisible under 100x oil immersion lens as relief). Is this OK for S.crinita?

I would accept it.
