oa 
49. Polystictus Fr. Nov. Sym. 70. 1851. — Founded on 
P. parvulus (Kl.) and a number of other species. A synonym of 
Coltricia Gray, proposed in 1821. 
50. Fomes Gill. Champ. 1 1682. 1878.— Founded on F. 
ungulatus (Schaeff.) [F. marginatus (Fr.)] and sixteen other 
species. The name was used by Fries in Nov. Sym. 46, 1851,, 
for a section of Polyporus. Karsten took up the name for gen¬ 
eric use in 1879, a year after its adoption by Gillet. 
51. Merisma Gill. Champ. 1:688. 1878.— Based on M. 
imberbe (Bull.) and twelve other species. Name preoccupied for 
nearly a century, being used by different authors for groups of 
fungi in which the fruit body was branched. Persoon used it 
for a group of the Clavariacese. 
52. Polyporellus Karst. Medd. Soc. Faun, et FI. Fenn. 
5:37. 1879.— Founded on P. polyporus (Retz.) [P. brumalis 
(Fr.)] and several other species. A synonym of Polyporus. 
53. Ischnoderma Karst. Medd. Soc. Faun, et FI. Fenn. 
5:38. 1879.— Based on I. rubiginosum (Schrad.) [P. resinosus 
(Schrad.)] and forms intermediate between this species and I. 
benzoinum (Fr.) A synonym of Trametes Fr. established in 
1838. 
54. Bjericandera Karst. Medd. Soc. Faun, et FI. Fenn. 
5 138. 1879.— Based on B. adusta (Willd.) and six other species. 
55. Inonotus Karst. Medd. Soc. Fann. et FI. Fenn. 5:39. 
1879.— Founded on In. cuticularis (Bull.), In. hispidus (Bull.), 
In. unicolor (Schw.) and In. hypococcinus (Berk.). 
56. Inoderma Karst. Medd. Soc. Faun, et FI. Fenn. 5 139., 
1879.— Founded on In. radiatum (Sow.) and several other 
species. Preoccupied by Inoderma Gray Nat. Arr. Brit. PI. 1: 
498, 1821, a genus of lichens. 
57. Antrodia Karst. Medd. Soc. Faun, et FI. Fenn. 5 140. 
1879.— Based on Antr. mollis (Sommerf.) and five other species. 
58. Hansenia Karst. Medd. Soc. Faun, et FI. Fenn. 5 140. 
1879.— Established on H. hirsuta (Wulf.) together with H. 
velutina (Fr.), H. zonata (Fr.), Ft. versicolor (L.), H. decipiens 
(Schw.), H. barbatula (Fr.), H. vellerea (Berk.), H. umbonata 
(Fr.), H. zonalis (Berk.), and other species not found in North 
America. Name proposed by Turcz, in Bull. Soc. Nat. Mosc. 
17:754, 1844, f° r a genus of the Umbelliferae. 
59. Polypilus Karst. Rev. Myc. 3:17. 1881.— Founded' 
on P. frondosus (Dicks.) and two other species, P. confluens (A. 
6 S.) and P. speciosus (Batarr.) [P. sulfureus (Bull.)] A 
synonym of Grifola Gray, 1821. 
60. Tyromyces Karst. Rev. Myc. 3:17. 1881.— Estab¬ 
lished upon T. chioneus (Fr.) and T. pallescens (Fr.). Difficult 
to distinguish from Bjerkandera Karst, and for the present at 
least considered synonymous with it.
