1 HE Fungi described in this paper were collected partly in Sierra Leone and the islands 

 of Biafra Bay, but for the most part in Angola and Benguella. Some were found near 

 the coast between 7° and 16° south latitude; but the greater portion occurred in the 

 highlands of the interior (from 120 to 260 miles eastward), which in Angola attain a 

 height of 4000, and in Benguella of 6000 feet above the sea. 



The present can only be looked upon as a fragmentary contribution to the Mycology 

 of Angola, inasmuch as, from the difficulty of travelling in so wild a country, and the 

 continual predatory wars of the Negro tribes, it is rarely possible to remain long enough 

 in one spot. At the same time we think that the many new forms here described an' 

 sufficient to justify the present publication; and, with the permission of the Limn 'an 

 Society, we propose in a subsequent paper to give an account of the Hymenomycetes, which 

 (especially the Polyporei) are rich in the number and variety of the species. 



PHACIDIACEI, Fr. 



Phacldium nitidum, Welw. & Curr. Peritheciis innatis, dimidiatis, interdum con- 



fluentibus, folii substantia concretis, orbiculatim dispositis, nigris, nitidis, in 8-4 

 lacinias latas dehiscentibus ; disco nigro-olivaceo ; sporidiis ovalibus vel irregularibus,

Obs. The specimens exhibit no asci, but only spores borne on sporophores. They are 

 not in a satisfactory condition; and it is possible that the asci may have been absorbed, 

 or that the plants are only in the stylosporous state. 



SPBJBRIACEI, Fr. 

 Xtlaria axillaris, Welw. & Curr. Stromate suberoso, nigro (sterili longiore et frag 



liore); peritheciis irregulariter sparsis, globosis, mamillatis; sporidiis mgro-fus-i 

 elliptico-acuminatis, 0-0010-00013 uncite longis.
