structure as curious as unexpected. A few will require to be re- 

 moved to the Hymenomycetous group, where one of these subter- 

 ranean genera, closely connected with Clavaria through Sparassis, ex- 

 hibits most beautifully the change which takes place in consequence 

 of a change of habit. Others, again, will fill up blanks among the 

 Ly coper donacece, and possibly amongst the Phalloidece also. The af- 

 finity of these two groups has been shown in this Journal, and the 

 circumstance of the ultimate condition of the fructifying mass when 

 mature being so different in the two groups, was considered as com- 

 paratively of slight importance. This is completely confirmed by the 

 genus Elaphomyces, which, though its contents are at length quite 

 dry and dusty, and intermixed with flocci, as in true Lycoperdons, is 

 nevertheless a certain ally of Tuber. An opportunity of examining 

 both our British species together in the spring, before we had seen 

 the work of Vittadini, had convinced us of this fact, and our views 

 are fully confirmed by the Italian mycologist. The spores are, in 

 fact, not born on sporophores, as in Ly coper donacece, but are contained 

 in globose asci or sporangia, as in Tuber. It is to be regretted that 

 M. Vittadini does not appear to have been well supplied with authentic 

 specimens of the more northern mycologists, and in consequence 

 there is some difficulty in ascertaining the synonyms. Our two 

 species of Elaphomyces are, however, clearly recognizable in Elapho- 

 myces variegatus, Vitt., which is our E. muricatus ; and E. asperulus, 

 Vitt., which is E. granulatus. Vittadini appears to have been the 

 first person who ascertained the true structure of the Ly coper dona- 

 ceous group in Bovista, though he was scarcely aware of the great 

 importance of the fact before him, which arose partly perhaps from 

 misapprehension, in common with all mycologists at the time, of the 

 structure of the hymenium in Hymenomycetes. Klotzsch, indeed, has 

 thrown fresh light in Dietrich's ' Flora Regni Borussici ' upon the Hy- 

 menomycetous genera of the monograph. We most cordially recom- 

 mend it to the notice of British mycologists, and hope that it may 

 be the means of bringing to light some of the hidden treasures of 

 our woods and plains.
