Fungus on Ochrolechia

Michael Haldeman, 12-10-2019 22:16

I found this fungus on the thallus of Ochrolechia laevigata on Alnus rubra in the USA, Washington near the Pacific Coast and near sea level in a maritime conifer forest. The fungus appears to only be growing on the lichen and not the adjacent bare bark or on other crustose lichens. The conidia range from 14-21 x 12-15 microns and consist of brown, spherical cells that are 3-4.5 microns in diameter.

Re : Fungus on Ochrolechia

Hi Michael.

Compare with Cheirospora botryospora?

Re : Fungus on Ochrolechia

Hi,

If the fungus is corticolous and not lichenicolous, it is a good idea but it does not seem to be the case. I think it would be good then to compare it to Lichenostigma alpinum. It could be the imperfect stage called Phaeosporobolus alpinus.

Re : Fungus on Ochrolechia

But it is true that macroscopically it looks like Cheirospora. As doubts remain, you should take a closer look at the conidiomata.

Re : Fungus on Ochrolechia

Thanks so much for the suggestions. Cheirospora seems like a good match.
