CEYLON FUNGI. , 57' 



broken, caespitose stalks : only one of the three specimens is 

 umbonate, though Berkeley and Broome give this as a charac- 

 ter : the gills are of course free ; only one of the three pilei is 

 shown in colour, and this has no trace of gi-een in the centre. 

 The group corresponds exactly with recent gatherings of 

 Psalliota subceruginosa , in which the pilei vary from yellow 

 with a green centre to pure yellow. The original specimens 

 ha^e been examined. 



12.— Panaeolus cyanascens, B. & Br. 



Pileus up to 3 cm. in diameter, hemispherical, ashy white, 

 smooth, covered with glistening particles, sometimes shghtly 

 ochraceous in the centre ; margin entire, with a bluisli tinge, 

 marked with raised radial ribs : young specimens viscid when 

 moist : flesh thin, white, turning blue when cut. 



Stalk 6-10 cm. long, 2-3 mm. in diameter, straight, equal, 

 white and shining, sprinkled with minute white particles, 

 becoming brownish when old, tomentose at the base, hollow : 

 in longitudmal section it is divided from the pileus by a deep 

 blue line. 



Gills adnate, broad (6 mm.), ascending, edge entire, gray, 

 becoming blackened with the spores. 



Spores intense black in mass, subglobose 14 x 11-12)", or 

 oval 13-14 X 7-8^*5 apiculate at both ends (lemon-shaped). 



The whole fungus turns deep blue when bruised. Gre- 

 garious, sometimes connate at the base. 



Berkeley's description, drawn up from the figures, says 

 " Albidus, cyanescens," " stalk deeply tinged below with 

 blue " : these colours on the figures show where the specimens 

 have been brviivsed. 



The herbarium specimen " 746 September, November, 1868," 

 is labelled Panceolus cyanascens and P. papilionaceus : the 

 spores all agree with the measurements given above, and 

 apparently the sheet contains one species onty : one specimen 

 resembles papilionaceus, but its spores do not exceed 14^. 

 " Panceolus caliginosus, Jungh.," was gathered {fide B. & Br.) 

 in September, 1868, with " papilionaceus " : there is no 

 labelled specimen in the herbarium, but the figures represent
