Species on genista/cytisus

Hello,
I found the following species on genista/cytisus. Max height 0,5mm with hairs with septa. I saw multiple types of spores: 
- Type 1: curved=>20/26x2,5/3µm with 2/4 septa
- Type 2: 4/5x2µm
- Type 3: 10/11x5/6µm

I can't figure out what spores belong to this species so I posted evrything I saw.

Does anybody knows what this could be?

Regards,

Ralph

Re : Species on genista/cytisus
Bonsoir Ralph, it's clearly Volutella sp.  An anamorph.

Hi Ralph,
there are several genera in your collection.
-image 1-3 = Volutella sp.
-image 4-6 = fusarium-like (conidia type 1)
-image 7 = Microthyrium ?

Regards,
Christian
