This is a possible mold growth due to humidity - Does it smell moldy?
>>> Do you think this is fixable ?
If this is mold growth . . . a copy and paste from:
http://www.leatherdoctor.com/killmold-3-6/
Mold is the colloquial term applied to a large diverse number of fungal species where their growth results in a moldy appearance on objects, including leather. A layer of fungal growth discolors such objects. Molds are fungi that grow in the form of multi-cellular filaments called hyphae. The hyphae are generally transparent, so the mycelium appears like very fine, fluffy white threads over the surface. The dusty texture of many molds is caused by profuse numbers of asexual spores formed by differentiation at the ends of hyphae. The mode of formation and shape of these spores are traditionally used to classify the mold fungi. Many of these spores are colored, making the fungus much more obvious to the human eye at this stage in its life cycle. Molds cause biodegradation of natural materials like leather. It can then be unwanted as a mold-damaged property. Mold requires moisture for growth. Like all fungi, molds derive energy not through photosynthesis but from the organic matter on which they live. Typically, molds secrete enzymes that degrade complex substances into simpler substances, which can be absorbed by the hyphae. Molds reproduce through producing very large numbers of small spores. Mold spores may remain airborne indefinitely or cling to leather and fur. It can survive under extremes of temperature and pressure.
