Characterized by the small spores, densely and finely echinulate hyaline epispore, and
numerous scattered, obscure germ-pores.
Although this form does not agree in all particulars with the description published by Dietel,
it resembles it too closely to allow of its being separated as a distinct species. It agrees in
most particulars with U. Dianellae Rae., so that this form is better classed as a synonym.
