Dasyscypha pteridophylla, n.s. Cupulate on a short 

 .slender stem, lemon-yellow throughout, about 0.3 mm. 

 diameter, clothed externally with short slender hairs, asci 

 cylindric, eight spores biseriate. Spores fusiform, acute, 

 hyaline, 16 x 1.5 ju. Paraphyses filiform. 



On stipe of Dicksonia, National Park. 



Rhizina atra, n.s. Discoid, black, plane, undulate, 

 bound down except on the margin by mycelial strands, 

 externally pruinose, mostly 1 cm. diameter, rather tough. 

 Asci cylindric, eight spored in one series. Spores broadly 

 oblong, dark brown, coarsely verrucose, 22 x 12 fi. Para- 

 physes filiform, clavate at the apex, brown. 



On ground, in woods, McRobie's Gully. 



Humaria tenacclla, J 'hi/. Cupulate, to discoid, ses- 

 sile, dark umber brown, externally paler and furfuraeeous, 

 asci cylindric, spores' elliptic, smooth, hyaline, 15x7 ^. ; 

 paraphyses filiform with clavate dark umber tips. 



On ground, Ridgeway. 



Humaria rutilans, Fr. Cupulate, 0.5-1 cm. diameter, 

 pale crimson to orange, externally slightly pubescent, 

 paler. Asci cylindric ; spores elliptic, obtuse, hyaline, 

 granular when mature 25 x 14 ll. 



On burnt ground, McRobie's Gully. 



Humaria mollispora, n.s. ' Hemispheric, sessile, fleshy, 

 pinkish-hyaline, 1 mm. diameter, exciple smooth, paren- 

 chymatous, disk plane; asci cylindric. eight spored. Spores 

 elliptico'- fusiform, smooth, hyaline, rather irregular in form 

 due to the spore wall being very thin, 18 x 5 /n. Para- 

 physes filiform with slightly clavate tips. 



Near //. omphalodes, Mass. 



Cascades, Hobart. 



Barlaea verrucosa, n.s. Hemispheric to plane, sessile, 

 crimson, fleshy, 1 mm. diameter, the exciple parenchymat- 

 ous. Asci cylindric, eight spores in one series. Spores 

 globose 20 ix. diameter covered with large hemispheric 

 warts even when young, hyaline. Paraphyses slender, 

 clavcrulate, crimson. 



On ground, Cascades, Hobart. 



Morchella tasmanica, J. Ramshottom. This is a Morel 

 often found in Tasmania, and hitherto referred to M. 

 esculenta, Linn. It differs chiefly in the oapitulum being 

 more cylindric, and the spores larger. The species is 

 described in the Journal of Ecology, Vol. VIII., No. 1, 

 March, 1920, from material gathered in Tasmania by Miss 

 Gibbs.
