I think I may have found the teleomorph of Dendros
An anamorph on the hymenium of Neottiella vivida

On October 15, 2019, I found several fruiting bodies on a heathland, which I determined on October 16, after microscopic examination, as Neottiella vivida. Two days later I repeated the examination in the hope that the spore ornamentation had improved. Instead, I found an anamorph. At first I thought of contamination but because of the presence of conidiophores this was ruled out. The, in first instance bright orange hymenium, was two days later covered with a black, powdery layer caused by the brown conidia.
Does anyone have experience with this anamorphic?
Thank you very much in advance,
François Bartholomeeusen

Re : An anamorph on the hymenium of Neottiella vivida
This looks like Harzia acremonioides (syn. Acremoniella atra). I have not seen this species, but I have cultured H. verrucosa, a very similar species with verrucose conidia. Harzia verrucosa is a mycoparasite producing typical contact cells on susceptible fungal hosts, so maybe your specimen was parasitic on Neottiella vivida.

Dear David,
Thank you very much, I could never have solved this problem on my own. For me this is one less UFO (Unidentified Fungal Object)!
Kind regards,
François
