of S. striata, but Montagne is decidedly opposed to this opinion 
and specimens are not at hand to settle the question. Compare 
his remarks on this point : 
“Si l'on ne considére que l’hyménium de ce Levwziées, il est 
évident qu’on le distinguera mal du Z. striata; mais si l'on ob- 
serve la disposition du duvet dressé et comme conglutiné qui 
forme les zones concentriques, la profondeur des sillons qui sepa- 
rent ces zones, et l’aspect rugueux et peluché qui en résulte, carac- 
téres que je ne rencontre dans aucun des nombreux individus du 
L, striata, on se convaincra promptement que, quoique voisines, 
ces deux espéces ne sauraient étre confondues.”’ 
Daedalea Burserae Pat. Jour. de Bot. 3: 341. 1889. De- 
scribed from plants found on rotten wood of Bursera gummifera 
in Mattinique by Duss. It is said by the author to be easily dis- 
tinguished from all its congeners by the yellow powder which 
covers its pores in the young stages. I have not seen the type 
plants.

nigricante, zonis obscurioribus, margine pallidiori, acuto ; intus 
cinnamomeo ; hymenio poroso-labyrinthiformi vel sinuoso-lamel- 
loso, subochraceo vel subcinerescente.”’ 
This species is very near to Sesia Berkeleyi. Further study of 
the type plants, however, is necessary in order to decide whether 
or not the two species are synonymous.

This genus was founded upon /sch. resinosum (Schrad.) and 
four other European species, the one here mentioned being the 
nomenclatorial type. Karsten describes the genus as follows : 
‘““Receptaculum pileatum, sessile, primitus subcarnoso-Suc- 
cosum dein induratum, crusta tenuiore tectum. Hymenium heter- 
ogeneum. Pileus azonus. Pori integri, demum subsecedentes.
