SECTION LENTUS. 



in most countries of the world. In the United States it is common in 

 the spring. In Europe it is of a southern range only. Frequent in 

 the tropics. 



SPECIES WHICH ARE CLOSE IF NOT THE SAME AS ARCULARIUS. 



squamiger (as Fayolus), Australia. 



cremoricolor, India. 



aemulans, Cuba. 



maculatus, India. 



tunetanus Algeria. Placed in Mcknopus, but I think belongs here. 



arculariellus, United States. The late summer form of areularius. 



arculariformis, United States. 



CILIARIS (as Favolus) (Fig. 475). This plant occurs in tropical America 

 and is very close to Polyporus tricholoma but with much larger pores and 

 close to Polyporus areularius, but with smaller pores. It was distributed by Ule 

 as a variety of Polyporus tricholoma. 



ORBICULARIS (Fig. 474). Known to me from one collection 

 at Berlin made in that vicinity, referred by Hennings to Boucheanus 

 but surely not that. It has a sublateral stipe and large, favoloid pores. 

 It seems to answer the description, but of course that is only a guess. 



LENTUS. Very much the same as areularius excepting its color 

 which is paler and the plant is more tough. Formerly collected, ap- 

 parently in abundance, on old stems of gorse (Ulex) in England, but 

 not in recent years. Recorded in error from the United States. 



MARMELLOSENSIS (Fig. 473). Known from but one speci- 

 men from Brazil at Berlin, which is most peculiar. Thin, dark, red- 

 dish brown with large, white, round pores. So thin it might be sought 

 in Polystictns or really in Hexagona from its pore shapes. It is the only 

 similar plant known. 



(Boucheanus, see Ovinus, page 168, probably better classed here.) 

 LENTUS SPECIES UNKNOWN TO ME AND NOT FIGURED. 



Incendiarius. Smooth, white, said to be "copious" in Russia, but unknown in the museums of 

 Europe. 



Penningtonia. South America. 



Velutipes, China. Said to have a viscid pileus and contorted pores. 



Fagicola. United Slates. Known only from the type locality. 



Variiporus, West Indies. Said to resemble Tricholoma, but has large pores. 



47. LENTUS. SUBGELATINOUS WHEN FRESH (TEND- 

 ING TOWARD LASCHIA.) 



GRACILIS. Smooth, reddish brown, small pores, with smooth, 

 reddish stem. When fresh it is subgelatinous. Several collections are 

 known, all from tropical America. Original at Kew from the West 

 Indies. The color of the dried specimens is reddish brown, but we 

 suspect that when fresh it is white. 



FORM. We have from Rev. Rick of Brazil a collection which we think 

 is the same species as the preceding but with notably larger pores.
