A split in the burgeoning world of facial-hair fundraising has seen two major groups promoting beard and mustache growth for charity part ways, according to The Wall Street Journal.

The 30,000-member American Mustache Institute, which works with organizations across the country on often tongue-in-cheek campaigns for a variety of causes, cut ties with the Movember Foundation over its refusal to back the tongue-in-cheek ‘Stache Act, an institute push for a federal tax break for facial hair.

The institute and its allies accuse Movember, an international organization that raised $132-million for men’s health last year, of taking the humor out of facial-hair charity and failing to support like-minded groups. Movember CEO Adam Garone said his group encourages other whisker charities, but under its charter cannot directly promote or raise money for causes other than men’s health.
