Albomagister is a genus of fungi in the family Tricholomataceae.

[1] Albomagister has a tricholomatoid stature and white gills with adnexed attachment.

It is unique in the Tricholomataceae due to the presence of long and conspicuous cheilocystidia and pleurocystidia, which arise from below the hymenium and are clear and thin-walled.

The lamellar trama is parallel and clamp connections are present.

Macroscopically, it resembles Tricholoma and Leucopaxillus, however the presence of prominent lamellar cystidia separate it from Tricholoma and the smooth inamyloid spores distinguish it from Leucopaxillus.
