MITREMYCES INSIGNIS (Plate 69). Rooting strands com- 

 pact. Exoperidium a gelatinous volva apparently "sloughing onV'f 

 Endoperidium smooth, yellowish. Spores large, globose, coarsely spinu- 

 lose, 15-17 mic. 



This species is known only from two collections from Ceylon, now 

 at Kew. 



MITREMYCES ORIRUBRA (Plate 69). Rooting strands 

 short. Exoperidium breaking up into coarse, wart-like scales and re- 

 maining adnate to the endoperidium. Spores large, globose, tuberculatc, 

 15-17 mic. 



The species is known from a single collection from the Straits 

 Settlement. It is readily distinguished from others by the coarse warts. 

 The name "orirubra" is not distinctive as all known species have "red 

 mouths." 



MITREMYCES JUNGHUHNI (Plate 69). Rooting strands 

 short. Exoperidium breaking into small adnate scales. Endoperidium 

 olivaceous. Spores large, globose, coarsely tuberculate. This seems 

 to be the most frequent species of the East Indies and India. It is close 

 to Ravenelii as to the exoperidium scales, differing widely in spore char- 

 acters. Collections are known from Java, Sumatra, Celebes, and the 

 Himalayas. 



SYNONYMS. Mitremyces Beyrichii is the mss. name under which specimens 

 were distributed; Calostoma Junghuhni a "new combination;" Mitremyces Sara- 

 sini| (Montsuma 1-24) Mitremyces viridis? (Jour. Bot. 51-201). 



THE HABITS OF DIPLOCYSTIS WRIGHTII. 



When Berkeley described Diplocystis Wrightii, he thought it grew 

 on a log. The plant, which I have abundantly received through the 

 kindness of L. J. K. Brace. Bahamas, and which is described in My- 

 cological Notes, page 141, plate 15, does not grow on wood as Berkeley 



(There are at Kew five or six specimens of this plant. All are free of the exoperidium 

 excepting one. This has a membrane attached to the middle of the stem somewhat as shown 

 in Berkeley's original cut made from this specimen. It impressed me as a gelatinous volva 

 that had "sloughed off," and in this particular specimen had been dried adherent to the stem. 



| Based on a specimen from the Celebes, now p-eserved in alcohol at Berlin. Externally, 

 the plant is M. Junghuhni in every respect. The difference in the tubercules of the spores as 

 shown is due, I think, to the fact that those of Junghuhni were described from dried speci- 

 mens, while Sarasini from spores preserved in liquid. If originally sent in formalin, it would 

 have produced just such an alteration on the mucilaginous epispore. 



I think the " green " idea in connection with the plant is overdrawn, and based originally 

 on a colored figure that was sent to Hooket from India. The dried specimen is not green, but 

 rather olivaceous, the same exactly, as far as I could see, in color and other characters, as 

 Mitremyces Junghuhni. 



NOTE. Calostoma Berkeley! is based on a single small specimen from Ceylon that 

 Berkelev had referred to Mitremyces lutescens (Linn. Jour. 14-78). It is Junghuhni. as far as 

 external characters go. I did not succeed in getting spores, which are described as being 

 smaller. 



Mitremyces Pachystelis (Husseya pachystelis, Ces. Born. p. 13, Calostoma pachystelis 

 n. c.i was "described" by an Italian from Borneo 'the plant was from Borneo not the Italian) 

 and figured as having an exoperidium an inch thick. I know nothing about it,
