IVIontagnites Candollei Fr. — Pyramid Lake, Aug. and 

 Mojave Desert, May. 3874 



Lycoperdon sculptcm. Subglobose or obovate 8 — 15 cm. 

 in diameter, pure white. Outer peridium very thick, form- 

 ing pyramidal masses, 2 — 4 cm. in breadth and 1| — 3 in 

 height, which are longitudinally grooved by many parallel 

 lines; in age dividing vertically into several segments which 

 usually remain attached at the apex: spore mass bright yel- 

 low, becoming cinereous: flocci yellow, 6 — 10 pi: spores 

 smooth pale, 5 — 8 pi. Plate I. 3580 



A curious and strikingly beautiful species. It is very 

 rare, and found only at considerable elevations, 6 — 8000 

 feet; in the Sierra Nevadas. In appearance it differs so 

 much from any species known to us, as to be almost deemed 

 worthy of generic rank. The structure however is exactly 

 that of Lycoperdon, the peculiar development of the cortex 

 being the chief difference between it and its congeners. 



The accompanying plate was lithographed from the pho- 

 tograph of one of medium size in my possession, and with 

 the exception of being much too dark is a fairly good repre- 

 sentation.
