tough, not phosphorescent. Spore elongated, 8'5 to 8'8 x 3*4 /x, 

 no cystidia. On upper surface of fallen trunk. Hawkesbury 

 River, December, 1914. (Herb., J. B. C, Form. Sp. 18.) 



136. Pleurotus subostreatus, n. sp. — Pileus up to 7 inches 

 broad and 4 inches from before backwards, convex, becoming 

 depressed towards its attachment, pallid whitish, matt. Gills 

 thick, creamy-white, anastomosing near the base to form a 

 network. Laterally attached by a short broad pallid to 

 brown matt stem, | inch long and § inch thick. Spores pear- 

 shaped, 4 x 2*5 /x. On a fallen log, Wauchope, N.S. Wales, 

 February, 1917. This species seems to approach Panus in 

 texture. It differs from P. ostreatus in the definite brownish 

 stem and in the small spores. 



Pileus ad 17*5x10 cm., convexus, albidus, subtomentosus. 

 Lamellae crassae, subflavo-albidae, ad basem anastomosae. 

 Stipes ad 2 cm. longus, lateralis, brevis, crassus, pallidus

137. Pleurotus Gheelii, Mass.: Kew Bull., 1907, p. 122; 

 Proc. Linn. Soc. N.S. Wales, xxxii. (1907), p. 202.— Small, 

 white. Pileus thickly hairy, attached by the vertex. Gills 

 radiating from the centre, moderately close, rather thick. 

 Spores thick-walled, subspherical, 6 to 8, 7*5 x 5"8, 8*5 x 7 jit. 

 On branches, Eden, Twofold Bay (portion of the type) ; 

 National Park, N.S. Wales, July, 1916. 



138. Pleurotus striatulus, Fr. : Icon., t. 89, f. 5; Saec. : 

 Syll., 1518; Cooke: Illustrs., 212b; Cooke: Handb. Austr. 

 Fungi, No. 184 (Q'land). — Our specimens, which have been 

 identified by Lloyd, may be described as follows: — At first 

 minute and cup-shaped, finally more open, sometimes fan- 

 shaped, sessile by the edge or excentrically, light grey to dark 

 grey, slightly striate, powdery looking. Gills moderately dis- 

 tant, darker grey than the pileus, sometimes with a brownish 

 tint, radiating from the downy base. At once reviving on 

 moistening (hence really a Panus J. On decaying branches of 

 a living cultivated mulberry (Morus alba, L.), Milson Island, 

 Hawkesbury River, June, 1913 (spores 5*5x3*6 jm) ; on a 

 twig (spores 6'8 x 4*2 /a) ; on dead wood (spores 3*5 to 

 7 x 2 /x) ; Manly, April; Sydney, May; Lisarow, June; Mount 

 Wilson, June — all the latter with subspherical spores, 4*8 to 

 5*5 /x (hence some doubt exists as to there being two species, 

 with oval and subspherical spores respectively).
