smooth. Basidia (teste Bourdot), globose, cruciate. Spores globose, 

 3^-4 mic., hyaline, smooth. 



The plant grows caespitose in the earth from a common, mycelial 

 base. It was named (Note 226, Letter 54) as Stereum cuneatum,

but on receipt of better specimens from Mr. Nelson, I suspected it of 

 being a Tremellodendron, and sent specimens to Rev. Bourdot, 

 France, who found the basidia, characteristic of this genus. It is the 

 only yellow Tremellodendron known to me. Atkinson describes 

 one from North Carolina (T. aurantium), which, however, from the 

 description, is different in form and spores. 



ISARIA FLABELLIFORMIS (Fig. 749). This is another 

 mysterious plant that we find often in the early season, growing on 

 frondose wood. It was named by Schweinitz first as Merisma nigripes,

and afterwards, when he claimed to have found perithecia, he illus- 

 trated with crude cut and named it Sphaeria flabelliformis. If it ever 

 has perithecia it would be called Xylaria flabelliformis now, and is 

 so compiled in Saccardo. While it is a common plant with us, we 

 think no one but Schweinitz ever claimed to have found any but 

 conidial spores. I have often observed it, and I never saw it develop
