And a diameter of 35-40 µ near the base, gradually contracted below and often forked at the base, tapering above into a bristle-like apex; asci cylindric or subcylindric above, reaching a length of 250 µ and a diameter of 20µ; spores 1-seriate, parallel with the ascus or diagonally disposed, at first smooth, sculpturing taking the form of distinct and regular reticulations, the ridge of the reticulations 1-2 µ depp and giving to the spore surface a very rough appearance; paraphyses about 2 µ in diameter below, rather strongly enlarged above.
