Found in Cupressus semprevirens

stipe 1-1,2 cm

diameter 0,2-0,7 cm

spores 10.3 [11.3 ; 11.8] 12.8 × 5.7 [6.2 ; 6.4] 6.9 µm
Q = 1.6 [1.8 ; 1.9] 2.1 ; N = 30 ; C = 95%
Me = 11.5 × 6.3 µm ; Qe = 1.8

at first I thought it was the trifoliorum, but the spores don't suit me, I also photographed the plants I saw near it.

Re : Sclerotinia sp.
The one ascus photo is important, it shows 8 equal-sized spores which excludes S. trifoliorum. Alsos spore size should be 12-18 x 6-7.5.  S. sclerotiorum perhaps?
