There is no specimen of this species at present in the 

 Berkeley Herbarium at Kew, hence the original diagnosis 

 cannot be supplemented. Berkeley says the present species is 

 somewhat allied to Pleurot^is versiformis, from Ceylon. 



79. Pleu7-ottis tasmanicus, Berk., Plor. Tasm., ii., p. 245; 

 Austr. Fung., p. 36; Sacc, Syll. v., no. 1510. 



Pileus reniform or semicircular, horizontal, even, smooth, 

 dingy-white or pallid, invested with a gelatinous stratum, 

 plane, or often depressed, and the margin acute and prominent, 

 1-5-4 cm. broad, produced behind into a very short tomentose 

 stem-like base, or sessile; flesh 3-4 mm. thick at the base, 

 becom.ing thinner towards the margin, soft, white, flesh of 

 stem or point of attachment dingy; gills radiating from 

 the point of attachment, rather broad, not crowded, with 

 numerous intermediate ones, dingy-white ; spores globose, 

 4-5 fx. diameter 



On rotten wood. New Zealand. Tasmania, Australia. 



Distinguished by the species having a gelatinous stratum on 

 the pileus, and by the pallid or dirty-white colour of every 

 part. The pileus is often depressed or concave, and the gills 

 correspondingly convex at maturity. 



80. Pleurotus diversipes, Berk., Flora Tasm., ii., p. 244, 

 tab. 181, fig. 4; Austr. Fung., p. 86; Sacc, Syll. v., 

 no. 1511. 



Pileus circular or more or less excentric, pellucid, 

 dingy-white, smooth, even, invested with a gelatinous stratum, 

 often more or less depressed or umbilicate, horizontal owing 

 to the upward curving of the stem, 3-5 cm across; gills 

 rather decurrent, not very broad nor crowded, not con- 

 nected by veins, whitish; spores elliptical, 5 x 3-3'5/>c; stem 

 variable in length, up to 3 cm. long, often shorter, some- 

 what cartilaginous, often compressed, hollow, attached by a 

 flattened or slightly discoid base, whitish. 



On rotten logs stumps, &c. New Zealand. Tasmania, 

 Australia. 



Distinguished among species having the pileus covered with 

 a gelatinous stratum by the hollow stem, which is sometimes 

 almost central, at others almost lateral, but always inserted 

 within the margin of the pileus ; usually curved when the 

 fungus grows from a vertical substratum. 



** Pileus never more tlian 1cm. across. 



81. Pleurotus cocciformis, Berk., Flora N.Z., ii., p. 174; 

 Hdbk. N.Z. Flora, p. 602 (as Agarictis (Pletiroius) cocci- 

 formis) ; Sacc, Syll. v., no. 1486. 



Scattered, minute, 3-5 mm. across, sessile, laterally
