Laschia thwaitesii. Berk, and Broome, Jouru. Linn. Soc. (Bot.), 

 xiv, p. 58 ; Austr. Fung., p. 167 ; Sacc, Syll. vi, no. 6508. 



Csespitose ; sub gelatinous when moist ; pileus convex, often 

 oblique, thin, even, orange or yellowish- ochraceous, very minutely 

 silky when young, 5-8 mm. across ; pores rather large, irregular, 

 yellowish ; spores elliptical, obliquely apiculate, white, 6-7 

 X 4 ju. ; stem variable in length, up to 1 '5 cm. long, sometimes 

 very short, slender, whitish. 



On dead stems of Rhipogonwn. Pohangina River, New 

 Zealand. Ceylon, Queensland. 



A pretty and distinct species, growing mixed with Marasmius 

 suhsupinus, Berk., and sent to Kew, along with many other 

 species, by Kirk. The pores are rather irregular, and in some 

 specimens almost resemble gills connected by high transverse 

 ridges. Differs from Marasmius in being subgelatinous when 

 moist. 



44. Merulius, Hall. 



Resupinate, or with the margin more or less free and reflexed ; 

 substance usually somewhat soft and inclined to be gela- 

 tinous ; pores very irregular in form, often formed from 

 slightly raised, wavy, and anastomosing wrinkles. 



Merulius, Hall, Helv., p. 150. 



Differs from Poria in consistency and in larger and irregularly 

 formed pores. Some species are destructive parasites ; others, 

 as M. lacrymans (" dry rot"), destroy worked wood. 



Merulius coriwn. Fries, Eleuch., p. 58 ; Sacc, Syll. vi, no. 6532 ; 

 Austr. Fung., p. 168. * 



Effused and resupinate, forming patches 3-10 cm. across, 

 upper margin usually free and reflexed, substance very thin, 

 flexible and tough ; pileus whitish, silky ; hymenium reticulato- 

 porous, from pale-ochraceous to tan-colour, sometimes tinged 

 lilac ; spores oblong. 8-10 x 3-4 /x. 



On trunks and branches. New Zealand. Australia, Tas- 

 mania, India, South Africa, Europe, United States. 



Substance thin, often separable from the matrix. The 

 hymenium is furnished with very slightly elevated ridges which 

 anastomose to form an irregular reticulation that disappears 

 towards the flat and sterile margin. 



Hydne.^:. 



The sequence of general form is the same in the present 

 family as in the Polyporew. In the highest types there is a more 

 or less thick or fleshy pileus supported on a central stem ; next 

 we descend to species having a lateral stem ; then the sessile
