Clathvopt jfch inm. 5 3 



Clathroptychium Berkeley!, Mass. (n. sp.). 



Hypothallus stout, not extending beyond the sporangia, 

 which are densely crowded, forming cakes 1 — 3 cm. across, 

 and 1'5 — 2 mm. thick, very minutely and indistinctly rugulose, 

 brownish-olive ; apices of sporangia almost plane, supported by 

 5 — 6 triangular, holloio threads, vjhich are strongly winged at the 

 angles, free edges of wings eroded ; mass of spores dirty olive ; 

 spores globose, warted, warts with a tendency to become elon- 

 gated, 10 — 13 fJL diameter.

(Type in Herb. Berk., n. 10857 a.) 



On wood. Ceylon. 



The large spores with the warts showing a tendency to 

 become elongated and form ridges, and the strongly-winged 

 threads supporting the apices of the sporangia characterize the 

 present species. 



Clathroptychium cinnabarinum, Sacc. 



Sporangia prismatic, broadly diffused, closely crowded, 

 \ — I mm. high, vivid vcriiiilion, above (operculum) blackish- 

 purple, rather shining, sessile, rising erect from a hypothallus ; 

 spores globose, smooth, 9 — 12 ju, diameter, vermilion, guttulate ; 

 threads descending from the operculum, filiform, thickish, 

 fuliginoiis. 



Sacc, in Michelia, I., p. 545 ; Sacc, Syll., Vol. vii., pt. I., 

 n. 1397. 



On decayed oak wood. North Italy. Forming flattened 

 heaps, 4 — 6 cm. long. Differs from C lathropt jjchiitm rugulosum 

 in the different colour of the mature plant, the narrow, prismatic 

 sporangia, and smooth, vermilion spores. 



The vermilion colour and smooth spores suggest the possi- 

 bility of the present being an immature condition of some 

 species. 



Clathroptychium dissiliens, Hazl. 

 Sporangia forming a rotund or oval cushion, 2 — 5 mm.
