PRAECURSORES AD MONO GRAPHIA POLYPORORUM. 
Ad cortices, ligno, &c. Venezuela. 
Appearance of very thin forms of P. vaporarius. 
1047. Poria (Vapor.) auricoma, Lev. 
Polyporus auricomus, Lev. in Herb. Berk. 2838. 
Ad cortice. Marquesas. 
We find no description of this. It is very like P. aneirinus , hut 
specimen too small and imperfect for diagnosis. 
1051. Poria (Vapor.) membranicincta, Berk. 
Effusa, tenuis, ochraceo-pallida, strato membranaceo pallidiore 
enata, margine lato, sterili, poris plerumque obliquis, mediis, sub- 
eequalibus, angulatis, dissepimentis tenuibus. — Polyporus membra- 
nicinctus, Berk, in Herb. No. 2909. 
Ad ligno emortuos. Tasmania, 1379. 
Pores often in patches, leaving spots of the membrane naked. 
1067. Poria (Moll.) porriginosa, Berk. 
Irregulariter effusa, immarginata, tenuis, pallido-rosea, poris 
valde irregularibus, inaequalibus, lacunosis lacunae angulatis, vel 
rotundatis, demum confluentibus, dissepimentis tenuissimis. — Poly- 
porus porriginosus, Berk, in Herb. No. 2934. 
On the ground ? Bombay. 
The very thin dissepiments break away in drying and leave 
large naked, rounded lacunas in the hymenium. 
1090. Poria (Rigidi) Bearimontii, B. fy C. 
Effusa, adnata, crassiuscula, ochraceo-pallida, margine angusto 
subtomentoso, poris majusculis, subaequalibus, rotundo-angulatis, 
dissepimentis acie acutis, integris. — Polyporus Beauinontii, Berk. 
& Curt, in Herb. Berk. No. 2919. 
Ad ligno. Alabama, U.S. 
1092. Poria (Rigidi) holoxantha, B. Sf Cooke. 
Orbicularis, dein conflueus effusaque, ochraceo-pallida, adnata, 
subrigida, poris majusculis, subsequalibus, rotundatis, dissepimentis 
tenuibus, margine acutis. — Polyporus holoxanthus , Berk, and 
Cooke in Rav. Amer. Fungi No. 213-214, Herb. Berk. No. 2848. 
Ad cortices Quercus et Myricce. Georgia, U.S. (Rav. 2402- 
2494). 
Pores smaller than in P. omcema. Some of these American 
species are doubtfully distinct. 
1093. Poria (Rigidi) omsema, Berk. 
Effusa, ochraceo-alba, rigida, e mycelio tomentosa albida consti- 
pata, subtus villosa ; poris mediis (J~l mm.), angulatis, integris, 
plerumque obliquis. — Polyporus omcemus , Berk, in Herb. No. 2837, 
P. radula, Rav. Amer. Exs. No. 107. 
Ad truncos. Pini, S. Carolina. 
1094. Poria (Rigidi) tomentocincta, B. Sf Bav. 
Effusa, adnata, subrigida, ochraceo-pallida, margine subtomen- 
toso, poris majusculis, rotundatis, aequalibus, dissepimentis crassius- 
culis, acutis. — Polyporus tomento cinctus, Berk, and Rav. in Herb. 
Berk. 2858. 
Ad cortices Quercus. Carolina, U.S. (Rav. 1771).
