NIDULARIA AUSTRALIS (Fig. 8, enlarged four times). 

 Pcridium cinnamon brown, subpulverulent, subglobose, dehiscing 12 in a 



circumscissile manner. Peridioles 

 small, about I mm., brown, rugulose 

 when dry. Spores 10-11x4^ (Tu- 

 lasne's measurement) . 



But one collection of this species 

 is known, made in Chile by Gay, and 

 preserved in Tulasne's herbarium. It 

 grows on rotten wood, and in many 

 of its features -strongly reminds us of 

 the previous species. The spores, ac- 



Fig. 8. 



cording to Tulasne's measurements, are relatively longer and the de- 

 hiscence (of the only specimen that shows it) is more regularly 

 circumscissile. 



NIDULARIA DURIAEANA (Fig. 9, enlarged 4 times). Peri- 



dium globose, brown, friable, scarcely exceeding i mm. in diameter. 



. Peridioles small, brown, about 



l /3 mm. Spores 65^-7x4^2-5 

 ( Tulasne's measurement) . 



This unique little species is 

 only known from a single col- 

 lection, made by Durieu in 

 Mauritius and now preserved in 

 Montagne's herbarium. It is 

 characterized by its very small 

 size, the largest peridia meas- 

 uring less than \y 2 mm. in di- 

 Fj 9 ameter. It grew on the naked 



ground in a little moss. From 



Tulasne's figure it would appear to grow on a piece of wood, but that 



is an error.

10 Excepting Holmsk. Beata Rur. T. 4, f. 2, which we think is a Nidula, not a Nidularia. 



11 Neither Roth who proposed the name Granularia, nor Miss White who juggled Tulasne' 

 genus Nidularia under Roth's name seem to have had a very clear generic idea of Tulasne's genus. 

 Both of them refer here Micheli's figure T. 102, f. 4, which clearly shows an epiphragm, and Micheli 

 states the peridioles haye funiculi and indicates them in his figure. The genus Nidularia has neither 

 an epiphragm nor a funiculus. 



12 The only specimen that clearly shows this character.
