Mycologia 



Fungi on Mosses. — Cladosporium epibryum Cooke & Massee 

 was referred to in the Bryologist for May and originally de- 

 scribed without indication of hosts. As they were all sent to 

 Dr. Massee, I wrote to inquire about them and received the fol- 

 lowing list of mosses as host species : 



1. Ulota phyllantha Brid. — Jaquina Bay, Ore. — T. Howell. 



2. Fabronia andina Mitt. — Ingenio del Oro, Bolivia — H. H. 

 Rusby. 



3. Hypnum megaptilum Sull. — Lake Pend d'Oreille, Idaho — 

 J. B. Leiberg. 



4. Bartramia Potosica Mont. — Sorata, Bolivia — H. H. Rusby. 



5. Grimmia ovata W. & M. — Canada — J. Macoun, no. 84. 



6. Grimmia Doniana Sm. — Spokane Falls, Wash. — J. B. Lei- 

 berg, No. no. 



7. Encalypta rhabdocarpa Schwgr. — Lake Pend d'Oreille — 

 J. B. Lejberg, No. 153 in publication. 



8. Bartramia pomiformis Hedw. — Lake Pend d'Oreille — J. B. 

 Leiberg, No. 153 in publication. 



These types are at Kew and duplicates of them are at the 

 New York Botanical Garden. The fungus occurs as black sep- 

 tate filaments protruding from the walls of old capsules, particu- 

 larly those that have wintered over, usually species of genera that 

 hold their capsules a long time. In the case of Ulota phyllantha, 

 they occurred around the mouth of the capsule, and the teeth were 

 so much distorted and undeveloped that it was difficult to de- 

 scribe the peristome in these, the first, specimens of this moss to 

 be found fruiting. — E. G. Britton.
