SUMMARY
A new species of Pseudoarachniotus, P. echinulatus, is described and illustrated. The morphological development and other diagnostic characteristics are given. P. echinulatus forms globose, echinulate ascospores which are purple-brown in mass and red-brown singly. These features serve to distinguish it from other known species. However, P. reticulatus and P. echinulatus are similar, and a list of differentiating characters is given.
