 252 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



Fructifications up to 25 cm. long, 5 cm. broad. 



On bark of Juniperus sabinoides. Texas. October. Only the 

 type collection known. 



Although occurring on bark of Juniperus, P. texana is not at 

 all related to P. laevigata and seems rather to belong in the group 

 of species of which P. flavido-alba is best known. The occur- 

 rence on Juniperus, the large expanse of the fructifications, and 

 large cystidia and spores should afford recognition of P. texana. 



Specimens examined : 

 Texas: Austin, W. H. Long, 21070, type (in Mo. Bot. Gard. 



Herb., 55134). 



37. P. flammea Burt, n. sp. 



Type: in Burt Herb, and N. Y. Bot. Gard. Herb. 



Fructifications effused, adnate, very thin, olive-ocher to deep 

 chrome, fading to clay color in the herbarium, hymenium often 

 with some granules, the margin thinning out, paler; in section 

 50-90 [A thick, not colored and with no color changes by potas- 

 sium hydrate solution, with hyphae 3 \l in diameter, interwoven 

 next to the substratum but suberect, branching and granule- 

 incrusted towards the hymenium; no gloeocystidia; wholly im- 

 mersed cystidia incrusted, 15-60 X 5-10 p., few and scattered; 

 hair-like cystidia not incrusted, 3-5 \l in diameter at base, pro- 

 truding 20-30 ^ beyond the basidia, are scattered in the surface 

 of the hymenium; spores hyaline, even, 33^-5 X 13^-2^ [x. 



Fructifications 1-10 cm. long, 5 mm.-2^ cm. broad. 



On rotting wood and bark of frondose species and on under 

 side of rotting leaves of Sabal. Florida, Alabama, Texas, Cuba, 

 and Bermuda. March to June. Probably rare. 



P. flammea has the intense yellow color of Corticium chrysocreas 

 and Odontia Wrightii but, unlike these species, its sections do not 

 become vinaceous and then bleach when treated with potassium 

 hydrate solution and the structural details of the sections are 

 quite different also. Peniophora sulphurina is yellow and has 

 small spores, but the fructification of P. flammea is as closely 

 adnate to, and inseparable from, the substratum as that of P. 

 cinerea.
