Rajchenberg, Mario. Corticioid and polyporoid fungi (Basidiomycota) that decay Austrocedrus chilensis in Patagonia, Argentina. Mycotaxon 81: 215-227. 2002.

ABSTRACT: Corticioid and polyporoid fungi that decay Austrocedrus chilensis in southern Argentina were studied. Only 52 Corticiaceae s.l. and 13 Polypores were found, pointing out this conifer as a rather poor substrate for these groups of fungi. Fibricium gloeocystidiatum and Tubulicrinis ellipsoideus are described as new taxa; the former is characterised by the presence of gloeopleurous hyphae and sulfonegative gloeocystidia and the latter by the combination of large ellipsoid spores and lyocystidia with slightly swollen apices. None of the taxa could be assigned to the species responsible for the white heart-rots present in standing trees. The following species are new records for Argentina: Aleurocystidiellum subcruentum, Hyphoderma echinocystis, Leptosporomyces galzinii, Trechispora praefocata, Tubulicrinis chaetophorus and an Antrodia sp. Most of the species are recorded for the first time on Austrocedrus chilensis.

KEYWORDS: Aphyllophorales, Corticiaceae, Polyporaceae, Wood-rots
