Hi,I wanted to share this collection on Rubus idae

« < 1 2 3 4 5 > »
Is this a lichenicolous ascomycete?
Jennifer Fiorentino, 04-11-2020 14:06
I collected this thinking it was an arthonoid lichen growing on the bark of an old carob tree in Mediterranean Malta. However on close examination I realised that the black, arthonoid structures were rather powdery, gave some brown, septate spores, 20-15 x 4.5 - 6 um. and seemed to be growing on the lichen Arthonia atra. Am I dealing with a lichenicolous fungus and could it be an ascomycete? Photos of A. atra and the black, powdery structures as well as some of the spores observed are shown.

Re : Is this a lichenicolous ascomycete?
Hallo, It is really hard to say from these pictures, but as for the brown spore, could this be a released ascospore from Rebentischia massalongii? I have impression that the narrowed left end of the ascospore on the last picture shows kind of hyaline cell. But maybe I am completely wrong. I am not the specialist. Zdenek

Hi,


I ddon't recognize old Rebentischia ascospores. It could be conidia of a lichenicoulous hyphomycete. But you have to show conidiogenous cells.
