Paragyromitra infula

Paragyromitra infula, commonly known as the hooded false morel or the elfin saddle, is a species of fungus in the family Discinaceae.

P. infula is found in the Northern Hemisphere, usually in the late summer and autumn, growing on rotting wood or on hard packed ground.

The fungus was first described in 1774 by the German mycologist Jacob Christian Schäffer as Helvella infula (the original genus spelling was Elvela).

[4] In an attempt to reconcile the confusion surrounding the naming and identity of the two mushrooms, Fred J. Seaver proposed that both were synonymous, representing variable forms of the same species.

The specific epithet is from the Latin infǔla, a heavy band of twisted wool worn by Roman officiants at sacrifices.

The cap of the fruit body (technically an apothecium) is about 2.5–9 cm (1–3+1⁄2 in) wide and tall, reddish to orangish brown, and saddle-shaped[10] with 2–4 lobes.

The spore-producing cells, the asci, are roughly cylindrical, eight-spored, operculate (opening by an apical lid to discharge the spores) and have dimensions of 200–350 by 12–17 |μm.

[10] The saddle-shaped cap of P. infula might also lead to confusion with some species of the genus Helvella, but these latter fungi typically have grayer colors and thinner, fluted stipes (e.g. H. maculata which has distinctly white flesh).

[26] Associated conifers include Picea glauca, P. mariana, P. sitchensis, Pinus contorta, P. banksiana, P. monticola, Abies balsamea, A. grandis, Pseudotsuga menziesii, Tsuga heterophylla, Larix occidentalis, Thuja plicata, as well as the deciduous tree species Populus balsamifera, P. tremuloides, Acer macrophyllum, Alnus species, and Betula papyrifera.
