400 PBTCH : 



and confined to the upper half in older specimens ; pale 

 yellow between the scales, whiter towards the margin which 

 is striate when dry; 1'8 to 2*4 cm. high, 1-5 to 2*2 cm. 

 diameter, flesh thin. Stalk up to 3 cm. high, 2 to 3 mm. 

 diameter, shghtly attenuated upwards, white, covered with 

 fine red fibrils or points, white and glabrous above, sometimes 

 longitudinally striate, hollow. Gills free, ventricose, broad, 

 (up to 5 mm.) white at first then black. Spores brown, 

 oval, 5-7 X 3-5 /*, black in mass on wood, but brown on 

 glass. On dead wood, usually dadap stumps {Erythrina 

 sp.). 



Coprinus miniato-floccosus Bres. & Pat. (Lloyd, Myc. Notes, 

 No. 6, p. 49) which is listed in Saccardo as C. miniato- 

 flexuosus, would appear from the description to be the same 

 species.

This species was Thwaites! No. 800, and was sent by him 

 with a coloured drawing. It is at first hemispherical and 

 umbihcate, but becomes infundibuHform later. The drawing 

 depicts three specimens, but these are all in the hemispherical 

 stage, and therefore Berkeley and Broome separated the 

 specimens into two species, naming the younger Russula peri- 

 glypta, and the older, fully developed forms, Hygrophorus 

 alutaceus. It is fortunate that the name Russula aliitacea is 

 preoccupied ; it would have been most inappropriate for the 

 present species. This species grows in large rings ; and here 

 and there in the rings one finds red specimens resembHng 

 Russula emetica. These are always deformed or irregularly 

 developed, with thick crowded gills ; they never bear spores ; 

 but always produce the conidial stage of a Hypomyces. I 

 have not yet been able to obtain the perithecia of the latter ; 

 its conidial form is of the VertieilUtim type.
