GENUS XXVIII. Favolus (favus, honeycomb). Favolus. 



Fr. Elench. p. 44. 



Hymenium reticulato-cellular, or alveolate. Alveoli radiating, 

 formed of the densely anastomosing gills, elongated. Spores 

 white (in pairs?). Dimidiate, somewhat stipit ate, fleshy, pliant, 

 annual, growing on wood, differing in entire appearance and 

 structure from the preceding genera, wherefore they were for- 

 merly referred not to Polypori, but to Cantharelli or Merulii. 

 Fr. Hym. Eur. p. 590. 



No British species. 



GENUS XXIX. Merulius. Fr. Syst. Myc. i. p. 326. Merufius. 



Hymenophore formed from a woven mucedinous mycelium, 

 covered with the waxy-soft, continuous hymenium which is 

 reticulated on the surface with ob- 

 tuse folds, imperfectly porous, at 

 length gyrose and obsoletely toothed. 

 Growing on wood, soft, mucedinous, 

 at the first at least resupinate. Fr, 

 Hym. Eur. p. 591. 



I. LEPTOSPORI (Aem-os, fine, slight ; 



a pore. From the shallow pore-like folds). 

 Hymenium naked or obsoletely pruinose 

 with the white spores. 



* Pileus effuso-reflexed, circumference de- 

 terminate.. 



** ftesupinato-effused, flaxy-membranace- 

 ous, separating, flaxy beneath and at the 

 circumference. 



! * Crustoso-adnate, somewhat flaxy at 

 the circumference. 



II. CONIOPHORI (KOI/IS, dust ; <f>fpo>, to 

 bear). Hymenium pulverulent with the fer- 

 ruginous spores. All destructive. 



LXX. Merulius lachrymans. One- 

 third natural size. 



I. LEPTOSPORI. Hymenium naked, &c. 

 * Pileus effuso-reflexed, circumference determinate. 



1. M. tremellosus Schrad. White, resupinate then free or 

 reflexed, fleshy -tremellose, tomentose, margin dentato - radiate. 

 Folds porous, various, ruddy. 



Sporting in form, becoming pale in hidden places, but easily recognised by 

 its gelatinoso-cartilaginous flesh.
