much in length in same peridiole, some measuring 12 x 16, others 

 12 x 22. It is a rare plant in Samoa, and I saw it but once. 



CYATHUS NOVAE-ZEELANDIAE (Fig. 14, 

 enlarged 4 times, from the type). Peridium 8-10 

 mm. high, cylindrical, cup-shaped, dark, almost black, 

 striate, appressed tomentose. Peridioles 2-2*^ mm., 

 black, with thin tunica. Spores 6x12 mic., el- 

 liptical. 



The type specimens grew caespitose on rough 

 bark, and were collected by Raoul in New Zealand. 

 The cups are darker, smoother, more cylindrical than 

 others of this section. We have seen only the type 

 specimens that we feel sure should be referred here. 

 We have a very similar plant from K. Miyabe, Japan, 

 but the material is so scanty we would prefer not to 

 decide. 



CYATHUS AMBIGUUS. (Fig. 15. 

 This species is known from very scanty type 

 material. The cups are of the same general 

 nature as those of Cyathus limbatus, but the 

 outer peridiole walls are not formed of coarse 

 fibrils, hence it is put in another section. It 

 differs from all the section in its very large 

 spores, stated by Tulasne to be 33 x 22 mic. 

 We have not found any spores in such perid- 

 ioles as we have examined. Fig 15 from the 

 type, enlarged four times. This species was 

 evidently doubtful to Tulasne, as its name 

 indicates. It is also very dubious to us.

CYATHUS BERKELEYANUS (Plate 107). Peridium 6-8 mm., 

 high, strongly striate externally, strigose hirsute. Peridioles i l / 2 -2 mm. 

 in diameter, black with thin tunica. Spores very small, 4-5 x 6-8 mic. 

 (In Mr. Millen's specimens, which we refer here, they are almost 

 globose. ) , 



No material is now to be found in the Tulasne herbarium, but the 

 types are at Kew. They were collected at Rio Janeiro, Brazil, by Chas. 

 Darwin. They are strongly striate and resemble small specimens of 

 limbatus. The plant differs from all other species in the striate sec- 

 tions in its very small spores. It was called by Tulasne Cyathus micro- 

 sporus var. Berkeleyanus, and while it has the peridiole and spores of 

 Cyathus microsporus, the cups are quite different, and I think Miss 

 White was perfectly correct in holding it as a distinct species. We 

 have an abundant and fine collection from H. Millen, Tobago, which, 

 however, has spores more globose than the type.
