species. The differences, however, appears to be varietal rather than, 

 specific in character, and lead us to regard the Australian representa- 

 tives of this species as a variety of the American type, 



Lamprospora TiBERCULATA, Seaver 



Ringwood and Castlemaine, Victoria, E, McLennan, September and. 

 October, 1921. 



This form is recorded here as new for Victoria, and the plants 

 examined coincide exactly with the description given by Seaver (9 

 and 10) of the American form. All their characters closely resemble 

 those of a Tasmanian plant Barlaea verrucosa. Rod. (11) and it is 

 probable that they are identical since Seaver regards the genus 

 Lamprospora as embracing forms described under the generic name 

 Barlaea [SaccJ and is defined by him as including " the smaller 

 plants of the globose-spored type of operculate Discomycetes, except 

 those which are commonly placed with the Ascoholaceae." 



L. tuberculata, Seaver, and L. areolata, Seaver, var. australis, McL.. 

 and C, occur in the same localities, and close to one another. In the 

 field they are quite indistinguishable, their external appearance being 

 identical; it is only after microscopic examination reveals the spore 

 characters that we are able to distinguish the two forms. 



IV. — CoRDYCKPS Fi BCATA, sp. uov. (Plate X.). 



Stromate simplici, stipite trifido. Aerio stipite brevi rubro-fusco 

 transverse fasciato, 6 mm. longo, 2 5 mm. lato, in tres pares et brev- 

 iores ramulos sursum diviso, qui capitula fertilia gerunt. Capitulo 

 clavato ovoideo rubro fusco 4-5 mm. longo, 25 mm. lato, in rostellum. 

 sterile desinenti. Peritheciis penitus immersis. Ascis linearibus,. 

 capitatis. Sporis octo, filiformibus, hyalinis in segmenta baculiformia 

 8-10 yx longa, 2^/, lata se dividentibus. 



Stroma single, entomogenous, stem trifid, continued below the sur- 

 face of the ground as a root-like structure, 17 cm. long, and tapering 

 from 2 5-1 cm. in breadth. 



Aerial stem short, stout, red-brown transversly banded owing to- 

 the disruption of the outer layer at intervals, and the exposure of the 

 more colourless tissue below, [Plate X., fig. 2] 6 mm. long and 2*5 mm. 

 broad, dividing above into 3 equal, shorter, and more slender branches, 

 each 2'5 mm. long, and 1*5 mm. broad, and bearing a fertile capitu- 

 lum. Capitulum clavate-ovoid, red-brown, 4-5 mm. long, and 2 5 mm. 

 broad, very faintly punctate with the dark-brown ostiola of the 

 perithecia, terminating in a small sterile, beak-like prolongation, 

 darker brown than the capitulum and 1 mm. long, by '5 mm. broad. 



Perithecia flask-shaped, deeply immersed in the tissue of the 

 stroma [Plate X., fig. 3 & 4], 460-500/x long, and about 135/x broad, each 

 opening to the exterior by an ostiole visible with slight-magnification 

 as a dark brown circular area on the red-brown surface of the capitu- 

 lum. Asci linear capitate, 6 5-8^x broad. Spores 8 filiform soon divid- 

 ing into numerous rod-like segments, 8-10^^ long, and 2 /a broad, hyaline.-

 McLennan & I. Cookson). September, 1922.
