I have found only two specimens of this species. The total 

 height of the fir.st is 12 cms. : the volva is oval, 3-5 cms. high 

 and 2*5 cms. broad, white, somewhat tomentose ; the stalk is 

 white and hollow, 1"4 cm. diameter at the base, 1*2 cm. 

 diameter near the top, where it divides into five equal arms 

 which unite again at the apex. The arms are about 4 mm. 

 diameter below and taper slightly up to the gleba-bearing part. 

 The total length from the point of origin of the arms to the apex 

 is 2' 8 cm., and the sporiferous mass occupies the upper 2 cms., 

 except at the extreme tip. The diameter of the head is 1*8 cm. , 

 the increase over the width of the stalk being due to a slight 

 outward bending of the arms and the thickness of the plates 

 which bear the gleba. 



The cross section of the stalk shows that the wall consists of 

 a single layer of large chambers, with occasionally a small 

 chamber wedged in here and there at the periphery. These 

 chambers are continuous throughout the greater part of the 

 stalk, and their radial walls are discernible exteriorly as longi- 

 tudinal striae to the number of about sixteen. Practically 

 then the stalk consists of sixteen parallel tubes arranged in 

 a ring. There are no external perforations such as occur in 

 the stalk of Dictyophora. 



At varying distances within the upper three centimetres 

 the wall between a pair of tubes vanishes, and so diminishes the 

 number seen in cross section, until at the point of origin of the 

 arms there are only ten tubes, two of which are continued 

 into each arm. 



The arms retain the structure of the stalk for a length of 

 about a centimetre, and in this part are transversely wi'inkled. 

 The cross section of each is roughly oval and is bisected by 

 the joint wall of the tubes which compose it. At the com- 

 mencement of the sporiferous portion this septum vanishes, 

 and the arm continues to the apex as a single tube. At the 

 same time the cross section increases from three millimetres
