Beneath, the tubes are very large, angular and dirty white ; in 

 fact, they are the largest in width of any species yet seen. The 

 stipe is short, thick and lateral, with tubes decurrent. It is solid, 

 tough and concolorous. When first seen the plant appears to be 

 sessile, and altogether very unique. 



Successive weekly trips were made to this location for some 

 time, but no results were obtained until late in the spring after 

 a long, cold winter, broken by one storm of exceptional duration 

 and precipitation. 



Late in March I visited the locality for the last time during the 

 season, and within a few feet of the place where the Boletinus 

 was taken, I found several specimens of Gyromytra which re- 

 semble G. escidenta very closely, but are apparently distinct. 

 The fall of this year, upon one of my first visits, I was again sur- 

 prised on the same spot with a single Boletus of large dimensions, 

 and distinct from any species ever seen here. It was not in per- 

 fect condition, however, the large stipe being nearly severed by 

 larvae. 



The pileus was very conspicuous, being a brilliant red color, 

 and covered with a dense jelly several millimeters in thickness. 

 It was circular, broadly expanded, margin thick and even, with 

 thick white flesh that turned slowly to a dirty-blue when broken. 

 This flesh was not infested with larvae, the short yellow tubes 

 but slightly so, and the stipe was almost totally destroyed. Like 

 so many others, this last year, but a single plant was found. It 

 is this search for the rare species that lends zest to the work and 

 pleasure in the constant new discoveries resulting from intensive 

 application to it. There is sport and excitement for the lover of 

 outdoor life. 



For some time during the winter of 1916-17, I made frequent 

 trips to a region just about six miles south of San Jose, to what 

 is known as the New Guadaloupe Mines. The topography of the 

 country is interesting from many points of view. That particu- 

 lar portion which I was then interested in, and still have under 

 observation, was a long, low ridge or two, very heavily wooded 

 on the eastern slopes with a second growth of Coast Live Oak, 

 Quercus agrifolia. It was the very nature of this growth that 

 invited careful investigation. Many trips were made, and ex-
