EXIDIA CAESPITOSA, FROM MISS A. V. DUTHIE, 

 SOUTH AFRICA. (Fig. 737.) Truncate, densely caespitcse, so 

 that it appears cerebriform. Color pale, amber brown. Imbedded 

 near the surface are slender, broken, deeply colored ducts (gloeocys- 

 tidia). Basidia not found. Spores not seen. This species has same 

 color and papillae as the Exidia purpureo-cinerea, differing in shape 

 and structure. The form is like that of Exidia truncata of Europe, 

 but its caespitose manner of growth, much paler color and smaller 

 size all distinguish it.

Phlebia meruloides. 



PHLEBIA MERULOIDES. (Fig. 738.) Resupinate. Color 

 Dresden Brown, margin narrow, paler, thin, not strongly distinct. 

 Hymenium meruloid (Fig. 739 enlarged), 

 same configuration as Merulius lacrymans. 

 Spores 3x5, hyaline, smooth, slightly curved. 

 I collected this recently at Eglon, W. Va. 

 It grew on rather firm, decorticate pole, lying 

 some feet from the ground over a small 

 stream. It was a puzzle to me, for while the 

 hymenium was meruloid, it was so different 

 in texture and appearance from all the 

 Merulius species that I could not believe it 

 was a Merulius. On drying, it becomes a 

 Phlebia and the texture, flesh and appear- 

 ance are of dried Phlebia radiata, and so 

 close to that plant that notwithstanding its 

 meruloid hymenium when fresh, I should put 

 it in Phlebia. This also throws some light 

 on the relations of the genus Phlebia. Fries classes it in Hydnaceae. 

 I have thought it was better in Thelephoraceae. Patouillard places it 

 with Merulius. I think now Patouillard is right. For me it is a de- 

 generate Polyporoid.
