hymenium is deteriorated but shows no cystidia; the species

Stereum insolitum Lloyd, Myc. Writ. 5. Myc. Notes 47: 665. 

 textf. 956. 1917, is a young specimen of Thelephora regularis

Through the kindness of Professor McFarland, I have exam- 

 ined his portion of the original specimen. Most of the spores 

 attached to the basidia are as published by Lloyd; a few spores 

 are 6-7X5 m, rough-walled and still hyaline; occasional spores in 

 a preparation from near the base of the pileus are colored and 

 tuberculate-irregular.
