unknown Mollisia species

Darvin kindly sent me the collection and I could examine it. It is a species not yet known to me, sharing some features with Mollisia fusca, but differing in a lot of characters. It is a KOH+ species, turning strongly yellow in KOH. The marginal cells are remarkable and subhyaline. The most striking feature is the excipulum, which consists of roundish brown cells as usual, but in two different sizes! I name this one in my provisional key Mollisia “heterocellularis” as a working title.

Mollisia spec., not ligni

this is a Mollisia spec., but not Mollisia ligni which has a iod-negative porus reaction. The species in Fungi of Switzerland named M. ligni is a misidentification. This one is called M. “pyrenopezizoides” nom. prov. in my provisional key. Macroscopically M. ligni is a dark species with a velvety, dark brown exterior. Ecologically M. ligni is a xerotolerant species, restricted to hardwood in dry and windy places, often on branches still attached to the tree.

What a gorgeous asco!
