the gills, acuminate or clavate with rough apices and swollen 

 bases, 43 to 48 x 8'5 to 10'4 jm. 



Usually densely caespitose with rooting mycelial strands 

 amongst or near the charcoal of burnt logs. Milson Island, 

 Hawkesbury River, May, 1913, and October and November, 

 1914; Spring Vale, near Dubbo, July, 1915; Suspension 

 Bridge, Sydney, April, 1915 (cap viscid). 



36. Flammula calif ornica, Earle. — The following is» the 

 original description (the reference we do not know) of this 

 species found in California: — "Gregarious or caespitose, 

 under trees, probably from buried rotten wood ; pileus 4-7 

 •cm., expanded, subumbonate, pale ochre-brown, umbo often 

 darker, glabrous, subhygrophanous, margin entire; lamellae 

 subsinuate-decurrent, heterophyllous, crowded, subventricose, 

 pale ochraceous to f usco-ferruginous ; spores ferruginous, 

 elliptic, 6-7 x 4 /a; stalk 5-6 cm. x 3-4 mm., subequal, 

 slightly enlarged at apex and base, glabrous above, brown 

 fibrillose below, base white mycelioid, bringing up attached 

 sand and fragments, pale brown, apex yellowish-white, solid; 

 flesh cream coloured, unchanging, taste and smell mild. The 

 glabrous subhygrophanous pileus places this species in the 

 section Udae. " The fact that this species was described from 

 America as being found in plantations of Eucalyptus directed 

 our attention specially to it. The form which we refer to 

 a new variety, var. communis, we at first thought might be 

 it. Compared with specimens of F. calif ornica, kindly for- 

 warded to the National Herbarium by C. F. Baker, and 

 identified by Earle, however, the spores are distinctly larger. 

 Though the spores of the specimens under consideration * are 

 somewhat broader and rounder than those of the American 

 F. californica, they resemble them closely, and the dry plants 

 appear very similar. Cystidia are common on our species and 

 its varieties, and we found a few in the American plants. 



We describe our collection as follows: — Pileus | inch in 

 diameter, convex, gibbous, not definitely viscid, centre brown, 

 rest yellowish. Gills adnate, moderately crowded, dull 

 greenish-yellowish. Stem 1 inch high, slender, hollow, 

 fibrillosely striate, pallid yellowish. No taste. Spores almost 

 subspherical or triangular, pale brownish microscopically, 

 5*2 to 6 x 4 jm. Cystidia ventricose, 40 x 10 jm. 



On the ground, Lane Cove River, Sydney, May, 1916. 



36a. Flammula. californica, var. communis, var. nov. 

 (pi. xi., figs. 3 and 4). — The following differs, more especi- 

 ally in the distinctly larger spores. It is relatively common 

 in the Sydney district and somewhat variable. Pileus up to 

 2 inches in diameter, convex, then flattened or upturned, 

 gibbous, viscid when moist, sometimes slightly streaky with
