46 PETCH : KEvisiONS or 



species : the list of Ceylon mycetozoa with recent additions 

 contains one hundred and three species. Similarly, all the 

 previously recorded Ceylon phalloids have been re-discovered, 

 with some additional species. But in other groups, our infor- 

 mation about the fungi of Ceylon must necessarily be doled 

 out in fragments : and it will entail a considerable reduction 

 in the names already existing. The results fully bear out 

 the contention that all collectors in Ceylon included in their 

 collections the common species, and that these have been re- 

 described each time under new names ; and that in any one 

 collection, the same species is described under different names 

 and in different genera. 



1. — Lepiota dolichaula, B. & Br. 



'^ Lepiota dolichaula, B. & Br.: pileo carnoso expanso 

 umbonato, centro glabro, alias punctate squamuloso, margine 

 lacero-appendiculato , carne alba immutabili : stipite elongato 

 stricto (base excepta), subsequali, apice penetrante, flocculoso 

 punctato cavo ; annulo amplissimo deflexo lacero ; lamellis 

 latis ventricosis remotissimis. — Thwaites, Ceylon, No. 694." 

 (Linn. Trans. 27, p. 150.) 



The pileus is almost plane except for the well-defined umbo 

 and the decurved margin. The umbo is pale or dark brown, 

 minutely tomentose ; elsewhere the pileus is white, covered 

 with minute, brown, widely- separated, dot-like warts ; 

 between the warts it is thickly covered with minute, white 

 granules, or almost glabrous. It varies from 14-19 cm. in 

 diameter, and the white, loose flesh is about 1*5 cm. thick 

 near the centre. The margin is appendiculate and decurved, 

 but only half covers the ends of the gills. 



The gills are ventricose, up to 2*5 cm. wide, rounded or 

 truncate at the outer ends, which are widely exposed, free, 

 somewhat distant. They turn yellow in drying, and are 

 pinkish where eaten bj'' insects. 



The stem is 29-42 cm. long, about 1-5 cnr. in diameter, 

 attenuated upwards, with a well-defined bulb 2-3 cm. in dia- 

 meter at the base ; white, mealy or glabrous, sunk into the 

 pileus for about a centimetre, hollow, lined with shining 

 white fibres, brittle : the inner layers are pinkish, and when
