Hi,I'm looking for these three standard references

« < 1 2 3 4 5 > »
Thecotheus formosanus var. collariatus?
Maria Plekkenpol, 03-10-2023 11:07
On cowdung I found these. Fb white, "sugarcoated", sessile, starting conical but then with broadened apex with hymenium sinking which makes it a bit cupshaped. No hairs, around 1 mm.
Asci cylindrical, quite narrow, 8-spored. 195-218 x 14-15, operculate, amyloid.Two types of paraphyses, both exceeding the asci:
1. hyaline, slightly capitate, apex 4,4-5,6 µ, filled with light yellow VB's
2. Hyaline, septated, very slender, not capitate
Spores ellipsoid and (quite a lot of them) amygdaliform, with cyanophilous and congophilous collarettes. In CB and CR verruculose. 17,9 x 8,8 Q= 2,03.
Can anyone confirm (or not) this determination? Thank you in advance!
Greetings, Maria

Hello Maria.

We can see the collars under the apicles on the spores, which with the ornamentation points towards this species. Nice find!

Hello Maria,

like Michel said this is without doubt Th. formosanus v. collariatus. It seems to be a very rare species.

I think this is still the only collection for germany!

Re : Thecotheus formosanus var. collariatus?
Hello Norbert,
First: thank you for confirming it too!
After arriving at this species with the key in 
"AN UPDATED KEY TO COPROPHILOUS PEZIZALES AND THELEBOLALES IN ITALY" by Doveri (2007) I searched the Internet and your post was one of the first I saw!
I was very excited to see everything I had seen in your find and description and the confirmation from Nobi (I am sorry, don't know his full name). I still posted it here, because of the fact that it is so rare: in the Netherlands also only one find by Ron Bronckers years ago.

Again: thanks for your reaction and what a beautiful passion we all have hahaha! 
Greetings, Maria
