Unusual fungal niches Dianese, Jose C [1], Pereira-Carvalho, Rita de Cassia [1], Chaves, Zuleide M [1]. Plant trichomes as a micro-habitat for hyphomycetes. In the Brazilian tropical savanna many plant species show phyllosphere containing a dense abaxial layer of trichomes. Covering those leaf appendages several fungi are commonly found [e.g. parasitic cercosporoid fungi in genera Pseudocercospora, Passalora, Stenella, and Parastenella]. However, most trichome-associated fungi are epiphytic hyphomycetes lacking a parasitic interaction with the host. A first species was described in 2003 [Janetia salvertiae], and three new genera [Trichomatomyces, Trichosporodochium, Phaeoidiomyces] were published in 2004, and eight more in 2009 [Trichomatoclava, Echinoconidiophorum, Globoconidiopsis, Globoconidium, Helminthosporiomyces, Microtrichosphaera, Phragmoconidium, and Vesiculohyphomyces]. The epiphytic condition of these fungi became clear in light microscope observations. As the micro-habitat considered has been overlooked by mycologists it is expected that this discussion will motivate further studies to reveal the real magnitude of the mycobiota associated with the plant trichomes.
