EDITOR'S NOTES. 



We are indebted to ]\fiss Hyde for an interesting^ account and 

 illustrations of a little bark-inhabiting fungus. 



Then Mr. Smith, teacher in the High School of Akron, places 

 us under obligation also. He gives us an account of a rare plant. 

 We have seen many of his photographs of fungi, besides the one 

 that illustrates his Peziza. We never saw finer ones — strong 

 language but justifiable. We will insist that he furnish may of 

 them for use in future numbers of the Bulletin. 



Mushroom literature is abundant and we resume our notes in 

 that field, even at the risk of bordering strongly on the technical. 

 Professor x\tkinson has in the past few years described many new 

 species. His descriptions are very full and careful and therefore 

 we desire to copy as many of them as space will permit. 



SCLEROTINTA TUBEROSA; TUBEROUS PEZTZA. 

 G. 1). Smith, Akron, Ohio. 



This is one of tlic very rare Pezizas tliat i)ro(luces a sclerotium at 

 the hase, and has Ijccn found Init few times in this country. It is said 

 to be much more common in Europe. Tlie photoji^raph illustrates very 

 nicel\' the oencral appearance of the plants. They grow in rich, shady 

 woods, sometimes luiprotccted, Init more often near stumps, logs, or the 

 projecting roots of trees. 1 have never found them except in early 

 spring, from April ]"> to May 20. These shown in the photograph 

 (Fig. 249) were found April 'M), in a ravine about two miles north of 

 Akron, Ohio. I noticed that they were very sensitive to different tem- 

 peratures in the explosion of their spores. When I would hold them 

 in the warm sun for a minute and then pass them suddenly into the 

 shade there would be a cloud of spores sent forth. 1 also noticed that 

 a sudden breeze would produce the same result. I then tried blowing 

 m\ breath on llivUi and the response was still greater. This T repeated
