Murrill: Polyporaceae of Noj^th America 637 



PoLYPORus ALBOSTVGius B. & C. Jour. Linn. Soc. Bot. lo : 

 309, 1868. Described from plants collected by Wright on dead 

 wood in Cuba as follows : 



'* Pileo e resupinatobreviter reflexo tomentoso pallido, margine pulvinato ; hymcnio 

 nigro ; poris minimis puncliformibus intus contexluque albis." 



**Pileus with pores 2 lines thick ; pores 1/180 inch in diameter, angular under a 

 high magnifier. A very curious species/' 



The type specimens at Kew are white above and within, while 

 the mouths of the tubes are very black. The name is well chosen.

This genus was established upon Polypoms suaveolens and its 

 allies, constituting one group, and Daedalca gibbosa, D. elcgans^ 



rubesccns, etc., constituting a second subdivision. Polyporus 

 simveolens is the type. The genus is characterized by Fries as 

 follows : 



** Hymenophorum omnlno immutatum et cum pilei substantia concolor inter jwros 

 descendit, Pori rotundati aut lineares, acii 

 gerrimi, numquam laceri. Pileus suberosus.

This species was first described from Lapland as follows : 



''Dimidiatus irregularisque, pileo glabro pallescente, poris rotundis albidoochra- 

 ceis. Boletus L. Fl. Lap. no. 522. In Salicibus Nordlandiae saltensis." 



" Odore pergrato et forti anlseo mcmorabilis. Interstitia pororum lacerata apparc- 

 bant, pori tamen iniegrl rotundi.'' 



The circumstances under which this species was established 

 are not satisfactory- The author had young, poorly developed 

 specimens, and he acknowledges that Linnaeus' plant, B. suaveo- 

 lens, was unknown to him, hence he, as well as Linnaeus, may 

 have confounded the two species. However, specimens sent by 

 him to Fries were considered distinct and his name was taken up
