Dear all,

This one has been collected on sooty mould on living leaf of Rubus fruticosus agg.:

Pycnidia superficial, gregarious, about 250 µm high, composed of a bulbous swollen ventor , about 85 µm diam., and a slightly tapering neck, dark brown. Neck composed of parallel hyphae of which the free ends expand forming a collarette supporting a hyaline, mucous droplet of condia.
Conidia oblong, with broadly rounded ends, 14,2-15,1x4,5-5 µm, 3-septate, thin-walled, hyaline.
Ass. Rachicladosporium ignacyi Piatek.

I did not succeed in finding appropriate literature about this species probably highly specialized on sooty mould. Any help is welcome.

Bernard
