Red pyreno on Pinus

Juuso Äikäs, 09-01-2020 21:59

This one was growing on the tips of a fallen Pinus sylvestris branch. Asci measure around 100 x 8-9 microns, around a million spores per ascus. Spore size avg. 3.5 x 1.

Re : Red pyreno on Pinus

Hi,

Please compare to Thyronectria pinicola or T. cucurbitula.

It would be useful to observe asci containing ascospores. Here you only show ascoconidia.

Re : Red pyreno on Pinus

Thanks for the suggestions. I tried to search for them but only those conidia showed up again.
