Hi

This black crusty material may be a fungal infection. Fungal infections may commonly affect the toe nails or finger nails in general. If this black material may be scraped off ,then you may need to have this assessed through KOH evaluation and culture. This will help exclude a fungal infection so that management may be directed towards the most possible working diagnosis.

At this point, I would consider a fungal infection first as this is fairly common. Have the crusts evaluated as results may help guide treatment.
