finally becoming free. Hymenium concolorous, often tinged broivnish 

 or lilac when old, smooth, minutely velvety. Flesh whitish, waxy, then 

 horny and parchment-like, thick, tough. Spores white, oblong, sub- 

 cylindrical, attenuated at the base, 5-8 x 2-5-4 /LI, "basidia 12-18- 

 30 x 4-5/it. Cystidia fusiform, subulate, often contracted, 40-100 x 

 9-16/z,, very thick walled, apex often incrusted. Hyphae very thick 

 walled, 4-7 //, in diam., with few clamp connections, subhymenial 

 hyphae thin walled, 2-5-3^ in diam." Bourd. & Galz. Stumps, fallen 

 branches, and needles of pines, rarely of other conifers. Jan. Dec. 

 Common, (v.v.) 



6. Receptacle at first waxy, becoming hard and rigid, closely adnate, 

 sometimes contracting when dry and becoming free at the margin, 

 or splitting and becoming inrolled along the cracks; varying in 

 colour from orange or brick red, to cinereous grey or brownish 

 bistre, passing through rose colour, purple, violaceous livid, etc. 

 The cystidia often commence as gloeocystidia with granular con- 

 tents which concentrate in vitreous or amber coloured masses, 

 more or less rugose and split up, along the inside of the walls and 

 incrust either the whole of the cystidium, or else only the upper 

 portion, in the latter case the cystidium appears as if stipitate : 

 the membrane of the cystidium is often torn and reabsorbed : other 

 cystidia oboval in the basal hyphae, narrowly fusiform in the trama, 

 have thick, smooth walls from the commencement.
