Myxotrichum  -   Gymnothecium

In mostAscomycota fruitbodies are protected by an outer peridium of pseudoparenchyma, In Myxotrichum, however, some of the outer hyphae form thick-walled, pigmented, stiff, bristle-like spines (setae) that radiate from the ascocarp . The ascoma is called a gymnothecium (naked fruitbody).  If the FB is disturbed by wind, water, mites, insects etc., the ascospores fall through the gaping holes in the weave for dispersal.
