SOUTHERN POLYPORES 19 



1. HEXAGONA ALVEOLARIS (DC.) Murrill 



Pileus reniform to circular, convex-plane, depressed behind, 

 3-4 X 5-7 X 0.2-0.5 cm.; surface at first fulvous, strigose- 

 squamose, at length pallid and almost glabrous; margin at first 

 thin, entire, incurved, becoming thicker and undulate or lobed; 

 context white, opaque, 1-2 mm. thick; tubes decurrent, white to 

 pallid, 2-4 mm. long, mouths 1-1.5 X 2-3 mm., edges thin, 

 rigid, dentate; spores ellipsoid, 10-14 X 4~4-5 fJ-i stipe usually a 

 lateral tubercle, at times eccentric or central, varying in length. 



Common throughout the southern Alleghanies on fallen 

 branches and other forms of dead deciduous wood. 



2. HEXAGONA DAEDALEA (Link) Murrill 



Pileus spatulate-obovate to reniform, applanate, usually 

 attenuate behind, 4-8 X 2-6 X 0.1-0.3 cm.; surface white when 

 fresh, radiate-striate, finely tomentose to glabrous, hispid behind, 

 tessellate near the margin, which is thin, often pellucid, undulate, 

 at times fimbriate, lobed or fissured with age; context fleshy, 

 fragile when dry, white, often partially translucent; tubes 

 decurrent, concolorous, 1-2 mm. long, 4~6-angled, mouths very 

 variable in size, 1-2.5 X 3-7 mm., smaller near the margin, 

 edges thin, but apparently firm, at length splitting into irregular 

 teeth; spores ellipsoid, 9-12 X 4~5 M; stipe lateral, concolorous, 

 hispid-tomentose, 0.5-1 cm. long, 2-5 mm. thick, usually dilated 

 at the base. 



Frequent on dead wood in the warmer portions of the Gulf 

 states. 



3. HEXAGONA CUCULLATA (Mont.) Murrill 



Pileus reniform, convex, umbonate-sessile, 3-6 X 6-8 X 0.2 

 cm.; surface glabrous, often radiate-striate, cream-colored to 

 ochraceous, plane or marked with two or three broad undu- 

 lations from center to margin, which is thin, entire, irregularly 

 undulate or lobed and deflexed when dry; context fleshy- tough, 

 white, 0.5 mm. thick; tubes ochraceous to dark-fulvous, hexag- 

 onal, not radially elongate, very variable in size, 1.5-3.5 nim. 

 long, 1-3 mm. wide, edges thin, finely denticulate; spores ellip- 

 soid, 14 X 7 fj.; stipe a mere scutate disk nearly a centimeter in 

 breadth. 



Occasional on dead wood in the southeastern states.
