Mollisioid fungus on cyperaceae

Enrique Rubio, 14-07-2016 20:34

Hi again

This fungus was found at the base of Carex sp. at 1700 m of altitude. Only six sessile apothecia, 0.4-20 mm in diam. over a well developped brownish subiculum. It has a mollisioid facies but the paraphyses have not refractive VBs and the asci are 4-8 spored. I think it is near to 'hemimollisia goldersbach! (Baral's Cubby) but the asci are shorter, the pore IKI rb, and it has less fusoid, shorter ascospores.

By the other hand I feel this fungus could be close to Dennisiodiscus

What do you think?

Thanks again

Re : Mollisioid fungus on cyperaceae

Great! Indeed I also suppose this is a Dennisiodiscus. It differs from D. prasinus in partly 8-spored asci, rather uncurved spores with obtuse ends, and lack of reddish pigment in the marginal hyphae.

I measured the spores as (10.5-)13.5-18(-20) x 3-4 µm. You din't see the anamorph?

Re : Mollisioid fungus on cyperaceae

No, Zotto. I didn't see the anamorph. Do you want these pics at higher resolution?
