Scutellinia problem
Ralf Dahlheuser, 10-08-2015 18:00
Ralf DahlheuserHello.

This Scutellinia is a mystery to me.


I have found it on swampy soil. Matured apothecia measures 5 - 15 mm. Marginal hairs not different from lateral hairs. Hairs are short, thick an brownish transluscent. Roots mostly unbranched, rarely bifurcate, thick walled, 1-3 septate. A very few Hairs are forked, one stellate. Ascospores verrucose and/or incomplete reticulate. Ascopsores wall not loosening when heateted in cotton blue.


Thank you.

Re : Scutellinia problem
Did you compare S. convexa/torrentis? I think there are only very few species with oil drops only near the poles, and my drawing seems here to fit quite well to your fungus.

Re : Scutellinia problem
Hello Zotto,

thank you for your answer.

S. torrentis was my first option. But: "Ascopsores wall not loosening when heateted in cotton blue".
I could always observed that in my previous collections of S. torrentis as yet.

But I do not know if that has to be always.

Re : Scutellinia problem
Hallo Zotto,

ja klar, hab ich.

Es passt eigentlich fast alles zu S.torrentis, bis auf das nicht ablösende Perispor.
