@MickeySegal would this be a positive culture or microscopic test?

Microscopic.

https://www.ncbi.nlm.nih.gov/books/NBK559024/ "Direct microscopic examination of infected hairs mounted on slides with 10% potassium hydroxide (KOH) reveals endothrix infection."

https://www.ncbi.nlm.nih.gov/books/NBK482477/ "Microscopically, these are seen as yeast cells which then produce hyaline hyphae that cutoff at the septa and those hyphal elements act as arthroconidia. Pseudohyphae and blastoconidia are also observed but no teleomorphic states. "

https://www.ncbi.nlm.nih.gov/books/NBK545178/ "DME of the crushed nodules under 10% KOH shows branched hyphae (4 to 8 microns) held together by a cement-like substance. The dematiaceous filamentous hyphae appear as chains of stout thick-walled cells resembling arthrospores. Visualization enhancement can be via lactophenol cotton blue and other colored dyes."
