Hello,

I don't have much experience with Nemania and would appreciate some help here. Spore size and germ slit lead me to N. aenea, but neither variant fits. MLZ+ reaction excludes var. aureolutea, inconspicuous germ slit excludes var. aenea, lack of white matter in stromata excludes var. macrospora. Or is it this large-spored form of N. serpens var. colliculosa: http://ascofrance.com/search_forum/46141 ? 

Czech Rep., lowland riparian forest. There's a small alder carr flanked by shrub Salix hidden in that forest and this Nemania grew there on a dead, partially decorticated Salix trunk, ca. 1,5 m above ground. Stromata rather soft, easy to cut. 

Thank you in advance.
