be confused with Trametes Muelleri, which may also be a 

 variant, but has small round pores and is more frequent 

 and constant. 



155. Lenzites bicolor. — On a dead stump of Callitris 

 robusta, R. Br., Pilliga Scrub, October, 1918; identified by 

 C. G. Lloyd (No. 509). In a note on these specimens Lloyd 

 says that they are the same as regards context-colour and 

 gills as Lenzites abietina, but the surface is pale (almost 

 white) and of a different colour to the context, and there are 

 dark zones on the surface, where this pale surface layer is 

 undeveloped. The upper surface view is the same as that 

 of Polystictus Friesii. Lloyd mentions that this is the only 

 Lenzites he has seen where the context-colour and surface 

 layer are not uniform. 



POLYPORACEAE. 



Boletus. 



156. Boletus romanus, Ottav. — The following species, of 

 which we have had prepared a coloured drawing, resembles so 

 closely the figure of "Boletus Romanus, Ottav.," given on 

 pi. xv. of Badham's work "On the Esculent Funguses of Eng- 

 land," that we consider, for the present at least, that we are 

 justified in calling it by this name. Unfortunately all that 

 Badham says of the species is as follows :— "The B. Romanus 

 was first described by Ottaviani, who obligingly sent a coloured 

 drawing of it (from which the present figure has been taken), 

 and a minute description, which I have unfortunately mislaid. 

 The site of this Boletus is on ground where wood has been 

 burnt, and it is brought by the 'Carbonari' in autumn when 

 they come with their charcoal to Rome." We do not find 

 the name in Fries. Our plants were described when gathered 

 as follows: — Pileus convex, splashed with madder-brown in 

 fibrils, yellowish between. Pores rounded near the stem, very 

 fine, rich sulphur-yellow. Stem stout, 1\ inches high, 1 inch 

 broad below, sulphur-yellow with slightly darker raised flecks. 

 Flesh showing a tinge of blue in places. Spores "mummy- 

 shape," greenish, 10'4 x 3'4 /x. Under Casnarina, North 

 Bridge, Sydney, April, 1916. 



157. Boletus scarlatinas, n. sp. — Pileus usually 1^ to 

 2 inches in diameter, but after heavy rains occasionally reach- 

 ing 3| inches across, convex to nearly plane, irregular, smooth, 

 somewhat viscid when moist (leaves may adhere to the 

 separable cuticle), brilliantly but often irregularly coloured 

 with tints of madder red, deep-orange cadmium, scarlet, 

 crimson or yellowish buff. Pores adnate, rarely with a slight 

 sulcus round the stem or slightly decurrent, in large specimens
