Mass-ee. — A monograph of 
pp. 65, 66, tab. i, f. 5 ; Sacc. Syll. v. 7. n. 205. (Type in Herb. 
Berk., Kew, n. 4475.) On sandy soil, Swan river, Australia 
(Drummond). 
In the text Berkeley has called the above species M. lundis , 
on the plate it is called M. lucidus , and in the description of the 
plate M. luridens , hence three names are given to the plant in 
the original description. 
The exoperidium disappears very early, the small persistent 
wart-like remains showing little or no structure. Endoperidium 
about 1 cm. in diameter ; stem-like base 1 cm. or less in length) 
and evidently more or less mucilaginous when growing, as it is 
studded with firmly imbedded grains of sand, and fragments 
of various kinds. Allied to C. Ravenelii , but readily distin- 
guished from this and every other known species by the black 
ostiolum. 
EXPLANATION OF FIGURES ON PLATE III, 
Illustrating Mr. Massee’s Monograph of the genus Calostoma , Desv. 
Fig. 1. Very young specimen of Calostoma cinnabarinum , showing the mucila- 
ginous external volva, a ; and the cord-like mycelium, b. Nat. size, after being 
soaked for some time in water. 
Fig. 2. Vertical section of Fig. i, after removal of the volva ; the thin red line 
is the commencement of differentiation of the exoperidium. Nat. size. 
Fig. 3. Transverse section of Fig. i. Nat. size. 
Fig. 4. Older specimen of C. cinnabarinum ; the volva has disappeared and the 
exoperidium is continuous over every part. At this stage the spores are mature, 
but the spore-sac still completely fills the endoperidium. Nat. size. 
Fig. 5. Transverse section of Fig. 4; a , exoperidium; endoperidium ; c, spore- 
sac ; d, gleba. Nat. size. 
Figs. 6, 7, 8. Mature condition of C. cinnabarinum ; a, remains of exoperidium ; 
b, endoperidium ; c, spore-sac extruded. Nat. size. 6, drawn from a dry. specimen ; 
7, 8, after soaking in water. 
Fig. 9. Ostiolum of Fig. 7. x about 10 diam. 
Fig. 10. Diagrammatic representation of the structure of the umbo in vertical 
section ; a, exoperidium ; b, endoperidium ; c, core of red tissue that eventually 
becomes disorganised and forms the centre of the ostiolum passing vertically 
through the umbo of the endoperidium ; d, spore-sac ; e , ostiolum and surrounding 
portion of spore-sac which remains in contact with the endoperidium after con- 
traction of the lower portion.
