Mas see. — A monograph of 
periods of development has been the cause of several mistakes ; 
even Schweinitz did not know the plant in the young condition, 
as proved by the following statement in his Syn. Fung. Amer. 
Bor. in Amer Phil. Soc., 1831, p. 255 : — 
‘ 1. M. lutescens , L. v. S., Syn. Car. 345; Sprengel, p. 518, 
rarius occurrit in Pennsylvania quam in Carolina, tamen passim. 
‘ 2. M. cinnabarinum ( Calostoma ), Desvaux et Brongniart, 
Bethl. et New York. Satis affine Mitremyci — sed peridium 
externum, corneum, coccineo-cinnabarinum, primum omnino 
clausum, demum deciduum et revolutim fissum in lacinias. 
Stipite prioris. 5 
It is evident that the above new species of Schweinitz is the 
young condition of his own M. lutescens. It is not quite clear 
whether the above specific character is original or a quotation; 
if the latter, I have not been able to trace it. Further, 
Schweinitz does not appear to have been acquainted with 
Desvaux’ original generic diagnosis, or that of the species 
(M. lutescens , Schw.) on which it was founded, as Brongniart 
is not mentioned in any way. The following is the description 
as given by Desvaux 1 : — 
‘ Calostoma , Sclerodermate spec., Pers. 
‘ Pediculus coriaceus, lacunoso-clathroideus ; peridium glo- 
bosum, cortice duplici ; exteriore coriaceo, apice aperto dentato 
persistenti, dentibus marginato-reflexis appropinquatis ; cortice 
interiore tenuissimo, pulvere copioso luteo filis multis inter- 
mixto. 
‘ Calostoma cinnabarinum , Scleroderma calostoma, Pers. 
page 15 du 2 e vol. de cet ouvrage, pi. 2, fig. 2. 
‘ Pediculo lacunoso ; peridio glob 0 so dilute purpureo, 4- 7 dentato. 
‘ Habitat in America boreali, supra terrain. 
‘ Obs. Cette plante est quelquefois decoloree, lorsqu’elle a 
ete dessechee sans precaution, parceque sa couleur, qui est 
seulement exterieure et ne penetre point dans le tissu de 
1’ecorce, exterieure du peridie, est formee par une espece de 
Pruine rouge, susceptible de se detacher.’
