Herbarium, According to Karl Mueller (Rabenh. Krypto-Fl. Lief. 4, p. 214), 

 the fruit is exceedingly rare and he was only able to examine fruiting specimens 

 from America. In Austin's "Hep. Bor-Amer. Ex." No. 145 is Riccia naian; 

 var. terrestris in fruit; the capsule measures i mm. in diam., the spores .06 mm.; 

 Mueller says .045 mm.-.055 mm., with 40 blunt papillae round the margin but 

 gives a figure with about 15. 



Austin published his tickets for his " Exsiccatae " in book form. In my copy, 

 by the margin of No. 145, he has written Riccia terrestris Austin. A curious 

 character of the species is that the teeth are coloured. The rhizoids are 

 described as being smooth, not papillose within as in Riccia; I have seen some 

 that are faintly papillose and others that have delicate strands in them, some 

 spiral. 



The type specimens from Africa are deposited in the Manchester Museum.

 FoLiosE Forms 



I am placing at the head of this group Anaptychia angustifolia and Alecioria 

 Loxensis, both really more at home among the fruticose forms. These two, how- 

 ever, simulate a foliose habit, growing over low mosses and hepatics, closely 

 appressed to the ground. The two plants look very much alike; so much so, that 

 in my first collection I gathered both, thinking at the time that I had only the 

 Anaptychia. A. angustifolia grows in partly illuminated and in very sunny 

 situations; in the former places I could not find it in fruit, but in the latter, it 

 fruited copiously. It was quite common. Alecioria Loxensis is much rarer, and 

 was found only in the more sunny places. Other species of Anaptychia collected 

 are the following: A.comosa, A.hypoleuca, and A . hypoleuca i . sorediifera. A. 

 comosa was found only occasionally, but A. hypoleuca, and its form sorediifera, 

 are quite common, growing on ledges of rock, exposed to the brightest sunshine. 



It is hard to say which of all the interesting genera belonging here interested 

 me most, whether Cora, Dict>onema, Sticta or Leptogium. Cora pavonia was 

 met at an altitude of about 4500 feet, and from that altitude on up to 5500 feet 

 it was met with frequently. It is found on the ground and on tree trunks. It 

 can grow in quite sunny situations, and also in moist somewhat shaded places, 

 where it covers the ground. In the sunn} places, and on tree trunks, it is less at 

 home, although specimens can reach quite a large size, many times larger than 

 when growing in the moist places where they are crowded. / 



Dictyonema sericeum is found only on decaying logs, and only in rather
