Found on horse dung.
Examining an unknown asco I found these coniophores on a stray spore from an unknown Cercophora. Althoough the spore is not mature yet I have some measurements.
Spore head: 19.5x11 um; head does contain one septe.
Pedicel: 43.5-44.5x4-5.5 um; pedicel has three septa.
Conidiophore: 15.2 um
I also included a mature spore head

In Doveri I found a description of Tripterosporella pakistani whereby he refers to phialides for these extensions. Also the fruitbody compairs with what I found.
I do not know if this immature spore originates from this fruitbody, it's a bit strange to find a stray immature spore of Cercophora there.

The Cercophora fruitbodies I found in the same substrate are very much different from this one.

Re : Parasitic conidiophore on sporehead of Cercophora mirabilis

These conidiophores are obviously the anamorph of the Cercophora. Here an example identified as C. ambigua

Hello Zotto,

 

I just read an article in Doveri where they talked about phialides for these extensions in Tripterosporella pakistani

These are the Phialophora-like anamorph of the telomorph.  Many Cercophora species produce these structures on their ascospores and in culture.
