NIDULARIA FUSISPORA. The only specimen of the genus 

 Nidularia that ever reached Europe from Australasia was collected 

 by Rod-way in Tasmania, and is now preserved at Kew. It is only a 

 little fragment of naked peridioles, but they present characters differ- 

 ent from those of the European species. In size they are only about 

 half as large, barely measuring y 2 mm. The spores present the most 

 marked difference, being narrower than those of other species. The 

 largest of them, according to my measurements, are 5x12 mic. 



NIDULARIA HERIBAUDII (Figs. 10 and 11). Peridium sub- 

 globose, light color, friable, containing a feiv large, black peridioles. 



Fig. 10. Fig. 11. 



Peridioles varying in size, the largest 3 mm. in diameter, black, smooth. 

 Tunica thin. Spores broadly ovate, 6x8. 



This species of Nidularia differs entirely from all others in the large, black 

 peridioles that are more of the nature of the peridioles of Cyathus, excepting 

 that they do not have funiculi. The peridioles seem closely packed in the cup 

 and are irregular in shape and size. The peridiole that we show enlarged 

 (Fig. ii ) appears to have a scar as though it had been attached by a funiculus, 

 but we have carefully examined all the peridioles of the specimen, and are 

 assured of the complete absence of funiculi. The type specimen (Fig. 10, 

 enlarged four times) is very scanty and was collected in the central part 

 of France on pine branches. It is now in the museum at Paris. We think 

 that Nidularia rudis. which was described from scanty material from California 

 (under the name Granularia rudis) will prove to be the same plant, and it is 

 an earlier name. We have seen no specimens, but should we examine them 

 and find them the same as those at Paris, will adopt the name (specific, not the 

 juggled, generic name). Our figure (10) is the type specimen, all that exists 

 at Paris (enlarged 4 diameters). Fig. n, a peridiole enlarged 10 diameters, 

 but few are as regular as this one. 



THE GENUS NIDULA. 



Peridium cup-shaped, opening by a thin epiphragm. The walls of 

 the peridium consist of two layers, the inner thin, which is continuous 

 with the layer that forms the epiphragm. In young specimens the 

 outer (thick) layer is readily peeled away from the inner (thin) layer, 

 but in old cups it is difficult to differentiate them. Peridioles free, 

 imbedded when moist in a mucilaginous substance and not attached 

 by funiculi. The genus Nidula is an excellent genus, recently pro- 

 posed by Miss White. It has the cup and epiphragm of a Crucibulum
