Murrill : Light-Colored Resupinate Polypores 85 



Country, Jamaica, January 12-14, l 9°9, W. A. Murrill & W. 

 Harris 1056. 



11. Poria cremeicolor sp. nov. 



Broadly effused for many centimeters over the smooth surface 

 of the substratum, continuous, inseparable, thin ; margin conspicu- 

 ous, indefinite, very thin, cremeous; context like the margin, a 

 mere membrane ; hymenium even, not glistening, uniformly 

 cremeous, becoming very slightly darker in dried specimens ; 

 tubes regular, rounded to somewhat angular, firm, becoming thin- 

 walled but remaining entire, less than 0.3 mm. long, 5 to a mm. ; 

 spores hyaline. 



Type collected on small, hard, decorticated hardwood stems in 

 Troy and Tyre, Cockpit Country, Jamaica, January 12-14, 1909, 

 W . A. Murrill & W. Harris 863. 



12. Poria adpressa sp. nov. 



Irregularly effused for many centimeters over decorticated 

 wood, inseparable, thin, following closely the inequalities of the 

 surface and also occupying the crevices and depressions ; margin 

 conspicuous, thin, white to slightly yellowish, closely appressed ; 

 context thin, white ; hymenium appearing in patches and then be- 

 coming fairly continuous, uneven, not glistening; tubes very 

 oblique, arranged as in oblique-tubed forms of Coriolellus sepium. 

 but much smaller, about 4 to a mm., larger by confluence, firm, 

 rather thick-walled, entire on the edges ; spores hyaline. 



Type collected on well-rotted, decorticated wood at Rio 

 Gavelan, Province of Santa Clara, Cuba, March 26, 1910, Britton, 

 Earle & Wilson 6033. This species has the habit of Coriolellus 

 sepium when growing resupinately on an upright trunk or stump, 

 but the tubes are minute and there is no tendency to form a 

 pileus. Young specimens collected on corticated wood in Cuba 

 (Earle & Murrill 167) and in St. John (Raunkiaer 204) appear 

 to have the same kind of hymenium, but its color is slightly rosy- 

 avellaneous, which leaves the identity of these specimens in 

 doubt. 



13. Poria tenuipora sp. nov. 



Effused for many centimeters, covering large areas, continu- 

 ous, inseparable, thin ; margin cottony, pure-white even in dried
