Thecotheus lundqvistii

Hallo everybody, On deer dropping in a moist box I grew a Thecotheus. Following Nordic Macromycetes Vol. 1 I end up with Thecotheus lundqistii. I found it very difficult to get the fungi mature, it took me more than 2 months to find free mature ascospores. The parafyses still don´t resemble the drawings and description of T. lundqvistii in Doveri. I assume, this is because of the difficulties of becoming mature and still not being fully grown.
Since it would be a new species for the Netherlands, I am very much interested if anyone can confirm my determination.
Best regards
Christiane

Hi Christiane.
Very interesting, but should be able to measure spore ornamentation and see better is to make a difference T.holmskjoldii and confirm the determination.?

Re : Thecotheus lundqvistii
Dear Michel,
I had T. holmskjoldii earlier on rabbit dung. The spores were much bigger. Also were the wrats more pronounced, spcially next to the apiculi. The fungi were easy to get mature. I have no expierence with measuring the ornamentation, when it is so small. Should I use Cotton blue to stain? I have very little material. The first photo is from T. holmskjoldii, the second fromT. lundqvistii.
Best regards
Christiane

Re : Thecotheus lundqvistii
Comparing your photos, your determination seems accurate. Should still be able to check the size of the spores. You can use as a dye cotton blue lactophenol, methyl blue, and blue ink.
Good luck.?

Re : Thecotheus lundqvistii
Thank you, Michel. The free ascospores from T. lundqvistii I measured were between 26-30 X 13-14 µm long. Beautiful photo from the spore of T. holmskjoldii! Thank you for showing! Great help for seeing the difference!
