New guinea (Berlin), Tropical Africa (Kew). As in the case of Hexagona 



albida, it is probable that it takes other hymenial forms. 



HEXAGOXA OCHROLEUCA ( Figs. 316 to 319 ).-\Ve shall not 

 enter here into any detailed account of Hexagona ochroleuca, for it is 

 usually not a Hexagona. In fact the name glabra is the only specific 

 name that was given to it as a Hexagona, although it has a dozen 

 other names, as Trametes, Daedalea, Lenzites, Sistrotrema, etc. Gen- 

 erally it is a Lenzites, and if we ever consider it in detail it will be 

 as a Lenzites, its usual form. 



Hexagona ochroleuca is the most polymorphic species known, I think, and 

 takes hexagonal, lenzitoid, irpicoid, and daedaloid forms, often in the same 

 specimen. Our figure (318) shows three distinct hymenial forms. The hex- 

 agonal forms are rare and the type of glabra (Fig". 317) is the only one so 

 named as a Hexagona, though several "species" of Trametes are based on 

 the same thing. I have seen many lenzitoid forms. Leveille named this speci- 

 men Hexagona glabra, and another specimen of the same collection (Roux, 

 India) he called in the same paper Sistrotrema ochroleucum. These plants 

 are in the same coyer at Paris, and they are surely the same species notwith- 

 standing the hymenium is so different. 



Hexagona ochroleuca has but few constant characters, none of a hymenial 

 nature, and can only be learned by experience. Its consistency, color of context 

 ( alutaceous, not white when fresh), surface, and distant plates are the main 

 characters by which it can be known from its equally abundant and equally 

 polymorphic neighbor. Lenzites repanda. Hexagona ochroleuca, in its various 

 forms as Trametes, Lenzites, etc., is a very abundant plant in India, Java, 

 Philippines, and the East in general, and also in Australia. 



We have not thoroughly investigated its synonymy, though we believe the 

 following should be included: Polystictus lenziteus (Zollinger Col.). Sistro- 

 trema ochroleucum, Hexagona glabra. Daedalea lurida, Daedalea pruinosa, all 

 by Leveille, who seems to have discovered it was a "new species" every time 

 he saw a specimen. 



Trametes Beyrichii (as to Berkeley's Philippine determination. Cummings 

 2202), 20 Trametes colliculosa from Ceylon, Trametes lobata from India, Trametes 

 laeticolor from Ceylon, Daedalea Hobsoni from India (or Australia?), 30 and 

 numerous recent determinations from the Philippines. 31 Daedalea Schomburgkii 



28 As to Fries, from Brazil, it is doubtful, as 1 Hexagona ochroleuca is not known from 

 America. No specimen of Trametes Beyrichii exists, and what it was is unknown. 



30 Daedalea Hobsoni was published in a paper on Australian fungi and was based on a col- 

 lection cited, made by Schomburg in Australia. Hobson collected in India, and Berkeley re- 

 fers to his specimen incidentally as "the original specimen," though never formally published. 

 Under these conditions our lawmakers ought to specifically tell us' which is the "type locality" 

 and which the "type specimen," as they put so much stress on those things. In this in-tano.- 

 I think it makes no vital difference, because both are the same plant. Cooke afterwards ,!i-cn\ 

 ered the "type specimen" of Daedalea Hobsoni. which Berkeley had labeled Daedalea Schom- 

 burgkii and sent Saccardo (cfr. Vol. 6, p. 376) a description of this interesting "new species," 

 though based on exactly the same specimen that Berkeley had described sixteen years before. 

 As evidence of the value of our literature Saccardo puts it in a different section of the genus 

 from the one in which he places Daedalea Hobsoni, although both were based on the same 

 specimen. 



31 It appears to me that Mr. Murrill's priority investigations were very superficial as to 

 these plants (as with most others). He uses the name Hobsoni (1865). and it has a dozen 

 names "prior" to that. Bresadola habitually calls the plant "Daedalea lenzitea (Lev.), l.r.-s.. 

 which was 1854, and Leveille had four names prior to lenzitea, to say nothing of Beifcetar - 

 discoveries. In the whole list it does not have a suitable name, or I should use it with( 

 regard to the date. Leveille's name ochroleuca is probably the best. I presume, however, 

 some enterprising individual could take the synonyms I have cited, look up their dates, ar- 

 range them chronologically, and produce weighty evidence why ochroleuca can r
