I agree it can be Chrysosporium. Other possibilities are also Scedosporium/Pseudallescheria. You should grow it for a longer time to observe possible changes in color of the colony (Pseudallescheria turns dark with time) and most importantly you should measure the size of conidia and possibly prepare a microculture on glass slide to be able to observe the morhology of hyphae and conidia-forming structures under microscope without destructing them during transfer from plate onto glass slide. The source of isolation may also bring some supporting facts, if it is from clinical sample, Chrysosporium can more frequently occur in nail infections, whereas Pseudallescheria in sputum of patient suffering cystic fibrosis.
Dear María Santamarina Siurana
Colony of fungi is white.I dyed it with Lactophenol Cotton Blue.
It is look like a Chrysosporium spp. You can also check this strain on Dermatophyte Test Medium (DTM) and verify the ability to grow at different temperatures. Different species among Chrysosporium genus are able to grow at different temperatures (max. temp.)
From Conidia shape and culture colour it looks Chrysosporium species
It looks like Chrysosporium. Please check out the taxonomic key in: (Rebell G, Taplin D. Dermatophytes their Recognition and Identification, revised edition. Coral Gables, Florida: University of Miami Press, 1979.)
Thanks
I agree: it looks like Chrysosporium. It even looks like C.keratinophilum. This species is common in soil, but can be also isolated from skin scraping. There is an excellent revision of this group of moulds by Lynne Sigler in Kane, Summerbell, Sigler,Kradjen & Land: Laboratory hanfbook of Dermatophytes Star Publish 1997
