Unknown asco on Cirsium vulgare

Marc Detollenaere, 13-09-2018 19:17

Dear forum,

Yesterday I found setous fruit bodies on rotten stems of Cirsium vulgare. At first sight it made me think of Phomatospora dinemasporium but the conidia( 17-21x3µ) were not curved and did not have setulae.

Any one could help me further?

Re : Unknown asco on Cirsium vulgare

One of my myco-friends suggested Colletotrichum.And indeed, it seems to fit.

With the key in Sutton, it leads me to Colletotrichum gloeosporioeides sl.

Could anyone confirm this?
