RE-APPEARANCE OF CYCLODERMA. 
By M. C. Cooke. 
In the seventh volume of “ LinnEea,” now fifty years ago, 
Klotsch described two genera of Fungi, both of which appear to 
have been unknown to, and puzzled mycologists down to the pre- 
sent day. The first of these was Testicularia , of which the original 
specimens, with the name in Klotsch’s own handwriting, are still 
extant in the Royal Herbarium at Kew. Whilst looking over a 
set of Ellis’s North American Fungi (exsiccati) we found there a 
species called by Peck Milleria lierbatica ) corresponding so exactly 
to the figure and diagnosis by Klotsch that it seems scarcely par- 
donable that these should have been overlooked, and a new genus 
and species constructed. But so it is ; Milleria herbatica , Peck, 
is no other than Testicularia cyperi, Klotsch, and both from the 
same locality. 
The other genus is Cycloderma , which pertains to the Gastero- 
mycetes. It was figured, and thus described in “ Linnsea ” : — 
“ Peridium duplex, exterius coriaceum, molle, interius discretum 
papyraceum tenuissimum. Columella scyphiformis, centro peridii 
interioris adnata. Capillitium radiatum, columellam et peridium 
interius jungens, sporis minutis, nudis inspersum. Radiculosum, 
stipite nullo.” 
Then follows the species Cycloderma Indicum , from the West 
Indies. 
Down to the present time, no mycologist seems to have met with 
a fungus, related to Lycoperdon and Scleroderma, which corres- 
ponded to the above description,* and the genus itself began to 
be regarded almost with doubt. 
Very recently we received from our correspondent, A. P. Morgan, 
of Ohio, a Gasteromycete which had puzzled our transatlantic 
friends, and at once we recognised in it the long lost Cycloderma , 
by the distinct columella and the radiating capillitium. This, how- 
ever, is not the precise species described by Klotsch, but closely 
allied to it. Externally it resembles some such a Lycoperdon as 
L. pynforme , but is firmer to the touch, and smooth. There is 
no appearance of somewhat obscure scales, as in C. indicum, and 
the apex, instead of being depressed, is obtusely papillate, or um- 
bonate. It may be thus described : — 
Cycloderma Ohiensis, Cke . Morg. 
Subglobosum, album, lawe. Peridium glabrum, coriaceum, 
superne umbonatum, inferne radicoso-fibrosum. Columella sub- 
* Unless the species named by Montague, Cycloderma Weddellii, can be 
excepted.
