spinulosum, Scleroderma vulgare, Catastoma circumscissa, Secotium 
rubiginosum, ? Tylostoma albicans, Tylostoma poculum. Mr. Sterling 
is the most satisfactory collector that is sending in specimens. He 
collects most abundantly. Hundreds of specimens of Mycenastrum 
spinulosum, show every variation from a rough scaly plant (no one 
else has ever sent) to the usual smooth form. A cigar box full of 
Tylostoma albicans, exhibits the plant in every form and shows that 
it has characters the author of the species never suspected. If 
every correspondent sent material as abundantly as Mr. Sterling, it 
would not be long before the last puzzel in relation to American 
Gastromycets would be cleared up. — G. E- STONK, MASS. Anthurus

187—HOW LITTLE WE KNOW. 
How little we know and how easy it is to be mistaken is strongly 
impressed on us by a recent experience. We received from W. Jekyll, 
Jamaica, what we thought were little “puff balls . They were t 
same collection and appeared to us to be the ripe and immature speci¬ 
mens of the same plant. On examination under a microscope we 
noticed little ‘ ‘balls’ ’ which we supposed were peridioles, which would 
have made the plant an Arachnion As the genus Arachnion con¬ 
sists of only one species as really known, namely, A. album, with 
which we are quite familiar, we readily supposed this was a new species 
of Arachnion and so wrote Mr. Jekyll. We forwarded specimens to 
Prof Patouillard and he advises us that we have two different plants 
What we had taken for the mature Arachnion being a Globaria, the 
scores ILlutinate by insects, and what we had taken for the young 
specimen?are specimens of the genus Endogone. In a re-examination 
of the ‘ hUle balls’’ and breaking them by pressure under a cover 
glass 6 we readily see our error in this respect. The genus Endogone 
easy it is to be mistaken.
