Lachnellula arida

Lachnellula arida

Lachnellula arida is recognized by cups that are brown and minutely hairy with a cream to yellowish hymenium. As suggested by the species name, it often fruits in dry sites where it would appear to be vulnerable to dessication. The ascocarps, however are resilient, shriveling in dry conditions, reviving when moisture returns, a process that can be repeated numerous times. Lachnellula arida is common throughout the montane regions of California and western United States. It is best seen in the spring following snowmelt, or after moistening summer thunderstorms.
