TROPICAL POLYPORES 



Context thick; plants very large. 20. LAETIPORUS. 



Hymenophore distinctly stipitate; context yellow. 21. PHAEOLOPSIS. 



Context brown. 



Hymenophore sessile, rarely substipitate. 

 Spores hyaline. 



Context light-brown. 



Surface glabrous or nearly so. 



Hymenium alveolate. 27. FAVOLUS. 



Hymenium normally poroid. 26. HAPALOPILUS. 



Surface distinctly hairy. 



Tubes small and regular. 23. CORIOLOPSIS. 



Tubes large and irregular. 24. FUNALIA. 



Context dark-brown. 



Context duplex, mostly of intricately woven 



black hairs. 25. TRICHAPTUM. 



Context simple. 



Context friable. 33. PHAEOLUS. 



Context tough. 



Tubes yellow. 28. FLAVIPORUS. 



Tubes brown, rarely greenish. 

 Tubes entire. 



Surface heavily bearded. 29. POGONOMYCES. 



Surface not bearded. 23. CORIOLOPSIS. 



Tubes soon splitting into teeth. 22. CERRENELLA. 



Tubes black. 30. NIGROPORUS. 



Spores brown. 



Hymenophore thin, dry, multizonate. 31. CYCLOPORELLUS. 



Hymenophore not as above. 32. INONOTUS. 



Hymenophore stipitate. 



Spores hyaline. 33- PHAEOLUS. 



Spores brown. 



Pileus inverted, pendant. 34. COLTRICIELLA. 



Pileus erect; stipe central. 35. COLTRICIA. 



Tribe 2. VOLVATAE. Hymenophore corky to woody, annual; surface smooth, 

 encrusted; context corky; tubes cylindric, concealed at first by a volva, which is 

 perforated at one or more points at maturity; spores hyaline. 



Pileus sessile, subglobose, white or slightly reddish-brown. 36. CRYPTOPORUS. 



Tribe 3. FOMITEAE. Hymenophore large, woody, perennial, rarely small or 

 annual; surface anoderm or encrusted, usually sulcate, sometimes varnished; 

 context punky or woody, variously colored; tubes cylindric, usually thick- 

 walled; spores rounded, smooth or verrucose, hyaline or brown; cystidia fre- 

 quently present; surface of pileus conidia-bearing in a few species; stipe rarely 

 present, the hymenophore usually being sufficiently elevated by its host. 

 Annual forms and species in a few genera connect this group with the Poly- 

 poreae; while the tendency at times to produce a daedaleoid hymenium, shown 

 especially in Porodaedalea, connects it with the Daedaleae. 



Surface of hymenophore covered with reddish-brown 



varnish; context punky to corky. 46. GANODERMA.
