Fig. 120. A, B, Femsjonia luteoalba Fr., entire and in section One-half 

 natural size, c, basidia and spores ; D, detached spores, the mature spores 

 are septate. X 500. E, G^lepin^a Femsjoniana Olsen. Three spores, one 

 germinating and producing sporidiola. X 500. 



2036a. F. luteoalba Fr. (from the yellow disc and white exterior ;
