a fibrous mycelium. Cortex white 

 or brownish, composed of long 

 slender spines, often curved and 

 convergent at the apex, which at 

 length fall away from above down- 

 ward, leaving a pale smooth sur- 

 face to the inner peridium. Sub- 

 gleba small, occupying scarcely 

 more than a fourth part of the per- 

 idium ; mass of spores and capilli- 

 tium greenish-yellow, then brown- 

 ish-olivaceous ; the threads mostly 

 thinner than the spores, much 

 branched. Spores oval, even, 5- 

 6x4-4.5^, usually furnished with a 

 short pedicel, 

 in. in diameter and about i in. in height. This

L. Cur'tisii Berk. in honor of Rev. M. A. Curtis, 

 bose, with a very short rooting base 

 and a slender fibrous mycelium. Cor- 

 tex consisting of a pale yellowish 

 farinaceous layer, covered by a coat 

 of soft, fragile white spines, curved 

 and convergent at the apex; after 

 maturity it soon disappears, leaving 

 a pale smooth surface to the inner 

 peridium. Subgleba small, but dis- 

 tinct, convex above and definitely limited ; mass of spores and capil- 

 litium greenish-yellow, then pale olivaceous ; the threads long, simple, 

 hyaline, two to three times as thick as the spores. Spores globose, 

 even, 3.5-41"- in diameter.
