Mitremyces. 



Mitremyces insignis (Berk.). This species was described by 

 Berkeley in Decades of Fungi, No. 185, as Husseia insignis. 

 In the Fungi of Ceylon, No. 705, Berkeley and Broome 

 enumerated three gatherings, viz., the type collection from 

 Adam's Peak (Gardner) ; a second by Thwaites, Central 

 Province, December, 1868 ; anda third by Thwaites, South 

 of the Island, July, 1868. In the Introduction to the Fungi 

 of Ceylon, Berkeley and Broome quote Thwaites to the 

 effect that he had always found Husseia on the sandy 

 margins of forest streams. Husseia is now considered to 

 be identical with Mitremyces. Massee adopted the name 

 Calostoma for Mitremyces. 



There are two specimens in Herb. Peradeniya, marked 

 " S. of the Island," collected by Thwaites. It has not been 

 collected recently. 



Mitremyces Berkeley! (Mass.). In Fungi of Ceylon, No. 704, 

 Berkeley and Broome enumerated a Mitremyces, collected 

 by Thwaites, as M. lutesc&ns. The gathering consisted of 

 two specimens only, one of which is in Herb. Kew and the 

 other in Herb. Peradeniya. Massee (Ann. Bot., II., p. 39) 

 re-described the Kew specimen as Calostoma Berkeleyi, 

 and stated that the spores were smaller than those of 31. 

 Junghuhni and less coarsely warted, and that the structure 

 and colour of the exoperidium were different. Lloyd 

 (Myco. Notes, No. 20, p. 241) writes that the specimen is 

 M. Junghuhni as far as external characters go, but that he 

 did not succeed in finding spores. 



Massee gave the spores of M. Junghuhni as globose, 

 coarsely tuberculose, pale ochre, 14-18 \l diameter, and those 

 of his Calostoma Berkeleyi as globose, minutely verruculose, 

 very pale ochre, 7-9 [x diameter. In the Peradeniya 

 specimen the spores are hyaline, globose, 7-10 y. diameter, 

 reticulated with narrow deep bands, which form a wide- 

 meshed net, and appear at the profile of the spore as a 

 hyaline border interrupted by yellow lines. The spores 

 resemble those of Trichia affinis, but with narrower 

 bands.
