 Petaloides Cayenner 



ALBELLUS (Fig. 439). Similar to the preceding but has larger pores. 

 White. From IncHa, also from Chas. O'Connor, Mauritius. 



MACULATUS. A spotted form (?), dark, known only from a single speci- 

 men, Malay. 



PLATOTIS. Known from a partial specimen (Australia). It seems from 

 the color, surface, and pores to be thick grammocephalus, but is much too thick, 

 and apparently does not belong to the section. 



b. PORES LARGE, FAVOLOID, RUNNING INTO FAVOLUS. 



EMERICL Pileus the same as that of the type form of grammocephalus. 

 but the pores are larger. From India. 



FUSCO-LINEATUS. This is an obese form of grammocephalus with a 

 short, thick stem, i-iJ/2 cm. thick. The pores are larger than the type form. 

 The surface is smooth, but lined. It was figured in the Trans. Linnenn Soc., 

 2d series, vol. i. 



FAVOLOIDES. (As a form of grammocephalus.) Pileus corresponds to 

 the type form of grammocephalus, but the pores are large, favoloid. I think it 

 is a better Favolus. Known from Africa. 



DORCADIDEUS. Color rich cinnamon brown. Surface vel- 

 vety-tomentose with soft, brown hairs. Marked with branched, vein- 

 like reticulations. Pores large, 2-3 mm. deep. Stipe short, lateral. 

 The surface is covered with simple, colored hairs, which have no rela- 

 tion to those of russiceps. There are no cystidia on the hymcimun. 

 This strongly marked species is known from but one specimen at the 

 British Museum, from Australia.
