marked feature is that of species that have large, colored imbedded 

 ducts. This is the third species that has come to my notice. (Cfr. 

 Seismosarca hydrophora, Myc. Notes, page 629, Seismosarca alba, 

 as Exidiopsis, Note 48.) The two previous have globose, cruciate

basidia. This has cylindrical basidia, hence must form a "new genus," 

 for it would not do nowadays to put tremellaceous plants with differ- 

 ent types of basidia in the same genus. 



DUCTIFERA. Gelatinous, foliaceous or cerebrine. Hymenium 

 amphigenous. Basidia cylindrical. Gloeocystidia deeply colored, 

 imbedded ducts. Spores hyaline, curved. 



DUCTIFERA MILLEI I. Gelatinous, when soaked out pale 

 brown, but drying darker, cerebrine, lobed. Tissue of fine hyaline 

 hyphae. Ducts (Fig. 1065) deeply colored, 

 6-8 mic. thick, irregular, often broken, dense 

 near the surface, forming a cortical por- 

 tion. Basidia not clearly made out by me, 

 but no doubt cylindrical.* Spores 6 x 12 

 hyaline, guttulate, curved. 



This grew on rotten wood near Quito, 

 Ecuador (Rev. Mille No. 4). In coloration 

 it is about the same as Tremella frondosa, 

 in form Tremella mesenterica, but in structure 

 it does not accord with any other species 

 Fig. 1065. known to me. 



We present two figures natural size. Fig. 1063 is the plant 

 soaked out; Fig. 1064 is the dried plant as received. 



*NOTE. Of the three types of basidia found in tremellaceous plants the 

 globose, cruciate and the furcate are always readily seen and easily found. The 

 third type, cylindrical, septate, we have never been able to clearly see, as shown in 

 the figures. We see indefinite, cylindrical bodies, no doubt the basidia, but although 

 we have tried often, we have never clearly made out the sterigmata nor the sep- 

 tation (excepting in Platygloea cfr. Note 263), but it is a safe proposition if one 

 does not find the basidia to be of the first two types, they belong to the third type.
