Dear Forum,On decorticated wood of Castanea,I foun
Hello,this Iodophanus grew on a dung of herbivore - I think everything fits well to I. carneus, except the size of spores.
Apothecia in groups, 0.5-1.5 mm broad, pinkish, pulvinate.
Ascospores 19-24,5 x 12-14 micrometers, ellipsoid, with visible nucleus (?) in the middle, distinctly warted (the warts measure about 0.5 micrometer), hyaline.
Asci 235-265 x 26-35 micrometers, amyloid in the whole lenght, octosporic, biseriate.
Paraphyses 4.5-5.5 micrometers broad, 6-11 micrometers at the apex, septate, containing little guttules.
Excipulum consisting of globose cells.
With the key by Prokhorov I came to Iodophanus testaceus, but it should be a non-coprofilous species... moreover, the colour is different in the photos I found.
So - I guess my fungus is simply Iodophanus carneus with larger spores... what do you think? (Dennis gives quite a broad span of spore size: 18-22(-30) x 10-12(-18) micrometers, Fungi fimicoli italici give 15-20 x 7.5-10.5 micrometers in the key, but 17-26.2 x 10-14.7 micrometers in the description).
Thanks, Zuzana
Indeed spore size sometimes can be quite variable; I think it is good to I.carneus. I enclose you the following article on the difficulties of separating I.carneus I.testaceus.
Michel.
there I am to the same opinion like Michel.
The differences with spores sizes in the FUNGI FIMICOLI... between some keys and the descriptions are often still more seriously and very much misleadingly.
Regards Peter.
