Nemania aenea var. ??
Viktorie Halasu, 11-09-2022 23:31
Viktorie HalasuHello,

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. 
Viktorie

Re : Nemania aenea var. ??
Hi Viktorie,
to me the germ slit you illustrate is conspicuous, or fairly conspicuous.
Inconspicuous applies to that of N. serpens, which is really difficult to make out.
Thus your collection fits well typical N. aenea.
Cheers,
Jacques

Dear Jacques,

thank you very much. Next time with Nemania I will have a better idea what is (fairly) conspicuous.

Best regards,
Viktorie
