Iodophanus hyperboreus?
Lothar Krieglsteiner,

.. found in the French Alps, 5.7.24, 1455 m NN, two quite large apothecia (about 2-3 mm) with beautiful rosy-pink tint growing on a very strongly decayed and water-soaked piece of wood lying in a fountain situation between mosses like Cratoneuron commutatum and Philonotis fontana, wet situation (in the surrounding nearly every habitat was fully dried out). The nitrogen-level was low which is indicated already by the mosses, and by spermatophytes (e.g. Parnassia palustris, Pinguicula vulgaris not far away).The sea level is perhaps a bit low, but I think I. hyperboreus should be a better choice than I. testaceus. I measured the spores with about 19-21/11,5-13 µm. My cotton blue stain was not very good working, maybe because of the very wet water-soaked material. The spores were finely warty . The paraphyses are perhaps distinctive, too - they are swollen and strongly guttulate.
Can I. hyperboreus be confirmed or am I fully on a wrong road?
Best regards, Lothar

Re : Iodophanus hyperboreus?
Why not simply I. carneus? It usually grows on dungs, but on a decaying substrate it might be possible...
To my knowledge, I. hyperboreus is terrestrial and has smaller ascospores.

Re : Iodophanus hyperboreus?
Hello Nicolas,
thanks for your opinion.
But ....
Medardi & al. 2006 for his new species hyperboreus: Sp 18-23/10-12 µm
In his key he gives for I. carneus measures of 17-19/10-11,5 and for I. testaceus 17,5-22,5/10,5-14,5
In Prokhorov 1997 I find for I. carneus 15-20/10-12, and for I. testaceus 18-22,5/12-13,5
My measures were (I repeat): 19-21/11,5-13
.
Wood (stronly decayed) or not wood is in my eyes less important than the nitrogen situation (carenus and testaceus are known as strong nitrophytes, and so I always found them before), I. hyperboreus grows at wet (and cold - ... yes) that are nitrogen-poor. I think the ecology is more like my find than that of carneus/testaceus.
Best regards, Lothar
