Abstract

SANDOVAL, Pablo; HENRIQUEZ, José L; FAUNDEZ, Luis  and  LARRAIN, Juan. First records of Eocr Onartium muscicola (Basidiomycota, Eocronartiaceae) in Chile on two new hosts. Gayana Bot. [online]. 2012, vol.69, n.1, pp.100-104. ISSN 0717-6643.  http://dx.doi.org/10.4067/S0717-66432012000100009.

The heterobasidiomycete fungus Eocronartium muscicola is an obligate parasite recorded on about 21 moss species, mainly from the Northern Hemisphere. It interacts with its hosts mainly by replacing the sporophyte and obtaining water and nutrients from the gametophyte through specialized tissues. This work reports for the first time E. muscicola on the native mosses Eurhynchium corralense and Eurhynchiella acanthophylla in central and southern Chile, in different forest formations. Also, associations between fungi and bryophytes as well as the taxonomic status of Chilean host mosses and its relationship with E. muscicola are discussed.

Keywords : Pucciniomycetes; Eurhynchiella acanthophylla; Eurhynchium corralense; moss parasite; Chilean Mycobiota.
