ill appearance of the cortex coat is due, I think, to Ellis' siiecimeu being 

 older than yours, and this coat having changed in drying. Your plant 

 was evidently collected in its ]ii'iine and the natural cortex coat well pre- 

 served." On account ft the notable peridial characters of this species 

 the generic standing has been uncertain. It was originally described by 

 Ellis and ICverhart as a Lijcojxrfh'ii and was lifted in Saccardo as a 

 Borisia. When ^Jr. Eloyd i)ublished his "(ienera of (Jastromycetes" (Bull. 

 Lloyd Lilirary. .Mycological Scr. Xo. 1) in ]J)02 he i)rovided in his key for 

 a genus J/ ii/iolilcwu s'')i:iral>le fKiiii tiie genus ('alnitia liy the jirest'iice of 

 an inner inenibranc such as this sincies possesses. On /'/. //, /■'///. '/Il, he 

 illustrates what he calls II mxihhiiiti pdcln/dc i iiut. .Vbout a year later in 

 Ills .Mycological Notes ( Xo. 14. p. HO. March, 1!»03) he described fully the 

 •_'('iius ]!i/])ohl( ma saying I bat it was ba-ed (ii Li/i-ojicrdon Jvp'ulophonnn. 

 .and referred to Jlijpohloiia IcijicloiilKiniiii as llie only sjjecies. His earlier 

 use of the specific name pachydcrma \\'as founded on the assumption that 

 it was a ]trior naiue for the same species. Further investigation, however, 

 convinced JJoyd that I'eck's Li/c'iprrdou luiclnidrnninn ( I'.ot. (Ja/,. 7:54. 

 1.S82) was a distinct sjtecles, .and he tuok up hiiiiloiiluii urn as tlic six'citic 

 name under the genus name II iiiiohhiini. Somewhat later the views con- 

 cerning the validity of this genus were altered as is evidenced by ;i note 

 (footnote 1.'!, ji. M. Index .Myc Wi-itings. vol. 1' I to tlu' effect that he would 

 class II jiiKihUhiii as ;i subgt'iius inxler Cttlnitin. In .i recent letter to tlie 

 writer .Mr. JJoyd has .-ig-Min expresst^d the oi»inion that the si)ecies should 

 i)e refeired to Cdlnitid. Moif/aii lias already described the si)eeies as a <'<il- 

 raliii. lint as be was .also nnstaUen in thinking I'eck's L. ixicfi iidt rniuni was 

 identical be u^ct\ the name ('(ilratia iiaclnjdcniui. This ernn* was further 

 perjietuated l>y :McIlv:iine (One Thousand Anarican I-'ungi. p. ~t^2) whose 

 des(ai]>tion clearly confuses the two jilants. Believing with Mr. Lloyd 

 that the peridial differences ]iresented by tiiis species can scarcely be 

 c<aisidered sulhcient for g(>neric se])aration the combination Calvatia 

 lepidophora is here adojited as the ]a'<iiier designal ion. The type sjieci- 

 mens of Ellis and Everharfs J.i/copcrddii Icjiidiiplioniiii were collected at 

 Huron, |South| Dakota, September. 1S84, by Miss Xellie E. Crouch. As 

 the Lafayette collection is tlu> second known collection very little can be 

 said aliout the distribution. It is evidently a very rare s]>ecies. B.oth col- 

 lections were made in the autumn. Xotbiuii was said abriut the original 

 habitat : ours was an ojien jiasture with muck soli.
