Roots? Fungus?

superficial roots Either poor watering habits that results in teh top of the medium staying wetter longer and causing roots to grow up rather than down, or erosion is also possible. Easy to discern which. Did you soil level decrease significantly? If not, it is your watering habits. When done properly there should be minimal to zero roots in the top 1-2" or so. In simplest terms: 1) fully satruate 2) wait for dryback and repeat The volume is learned retroactively and not a pre-ordained choice. You use what it takes to accomplish the task not a volume you randomly chose to give. If you wait for same dryback/loss of weight, it will require a similar volume each time. Time between wil vary if you use a proper trigger - like dryback or loss of weight. Again, not something that is preconceived but rather a simple reaction to an observance. observe and react... not some top-down "I give 1.5L ever 2 days" If this is soilless, also incredibly important to get a minimum 10% runoff to avoid buildup of nutrients in the medium over time. If that doesn't sound familiar, you found the cause of your superficial roots. In regard to random fungi you'll often see in soil - it's rarely a concern. It's feeding off of some decaying organic material. It generally won't directly hurt the plant or not in any way that is concerning. you'd defnitely see some problems above ground if it was damaging the roots -- just as you would with various pest larvea chewing up roots. droopy, unhealthy, smorgasborg of symptoms when advanced.
