Finally did them a design! Also picked a name, and didn't come to anything better than variation of mycelium.

I saw this photo online with a guy who saw individuality in mushrooms and took pictures of each one individually... And I just immediately thought that this is something some Magos Biologis might do, and now I'm going to make myself one.
They don't have a name yet, but I think they were born on some agro-world where the Adeptus Mechanicus plays an important role, even if the world doesn't belong to them. It all started with some common mushrooms for the world that piqued their interest, but then they found out how diverse mushrooms can be and made this the direction of their research.
They spent a lot of time in the cave systems of the agro-world, which were of no interest to production, and therefore were not particularly developed, but there were many little-studied species of mushrooms. Then one home world became not enough for them, and they wanted to study some unique species of mushrooms in a jungle world or somewhere else. They aren't very interested in anything other than mushrooms, so they wouldn't become an Explorator in the service of a Rogue Trader, but would travel with their retinue on passing Imperial ships.
They definitely have a collection of infocrypts with picts of every mushroom they've ever seen. And a collection of flasks with pickled specimens of their favorite species. They wear them on their belts, but only show the most valuable ones to those they trust.
I think they have some kind of experimental technology based on mushroom mycelium, so the non-augmented part of the face is distorted beyond recognition by spores. And the mushrooms are also growing somewhere from the mantle, on the sleeves, from under the hood or on the back.
Their tech-brothers on the agro-world took this in stride, although the laity were frightened by the appearance of the magos. So it came as a great surprise to them that outside their home world, the Inquisition, the eclisiarchy, the laity and even other Adeptus Mechanicus ask a lot of questions and accuse them of Chaos worship. No Nurglite, they are just a chill guy who likes mushrooms!
They are introverted. They like quiet places and do not like to be around many people. They answer briefly and monosyllabically, and prefer to remain silent unless the topic of conversation is mushrooms. They appreciate and respect those who accept their hobby, and may even give something as a gift just like that. After all, they are magos, and can do many things besides their specialization. They especially value their retinue, because they do not want strangers around them, even if they are loyal.
