PUFF BALL LETTER NO. 4. 



Cincinnati, May, 1905. 



The following persons have kindly sent us specimens since our last 

 acknowledgment, and will be continued on the mailing list of Mycological 

 Notes. This publication is issued principally with the object of interesting 

 collectors in picking up specimens and sending them to our museum, and 

 we can not promise to continue to send to those who do not take this much 

 interest in the subject. 



We have made what we feel is a very thorough study of the "puff ball" 

 families, not only of the United States, but of the world as far as known. 

 We have .seen and studied all the specimens that are preserved in the prin- 

 cipal museums, which embrace practically all that are described. The genus 

 Tylostoma has not been worked up, but otherwise we feel familiar with 

 practically all the known species. Outside of these families, however, we 

 claim to have no critical knowledge, only a general knowledge of tbe current 

 names of the common species. We list the specimens received that we know 

 under these names. Others, when we do not know the species, are listed 

 under the genus only. 



We are glad to get material of any fungus of a firm nature that retains 

 its characters when dried (see circular enclosed). C. G. LLOYD.
