Distinguished at once by the numerous brown cystidia

 and the coloured spores. Sometimes almost completely covering 

 the under surface of fallen logs. When moist dirty ferruginous 

 passing to mulberry- colour, rigid when dry. adnate, margin more 

 or less free all round, often lobed, or free and reflexed above, 

 rugulose. Hymenium often cracked when dry in lines radiating

HymenochcBte rhabarharina, Cooke, Grev., viii, p. 148 ; p.. Sacc, 

 Syll. vi, no. 7467. Svn., Corticium rhaharharinum* Berk. ^
