Irregular Ionomidis (Ionomidis irregularis)

Small, clustered lobes, densely seated on short stipes. The outer surface is brown with an olive tint, covered with a powdery layer that rubs off easily. The hymenium is smooth, changing color from olive-black or violet-black to nearly black as it matures. The inner layer is gelatinous.
Elastic, leathery.
Weak odor of decaying wood and musty meat.
Spore print white. Spores ellipsoidal, with large droplets. All parts of the fruiting body turn a drop of alkali purple.
Xylotroph. The fungus is associated with deadwood and decaying wood of broad-leaved trees. It can be noted that in some cases a wide trophic specialization is observed—the fungus has been recorded on deadwood of birch, alder, and elm. However, when beech is present in the region, the fungus most often colonizes this substrate. The species is considered a good indicator of undisturbed forest ecosystems.
Status 2 — vulnerable species.
Limiting factors: association with habitats rare in the region. Logging, construction of linear infrastructure, and development lead to fragmentation, reduction, and destruction of potential habitats, as well as removal of suitable substrates for the species.
Conservation measures: a ban on development, clear-cutting, and construction of linear infrastructure in the species' habitats is necessary, along with the establishment of planned protected natural areas.
Status 3 — vulnerable species.
Conservation measures: A ban on logging in parks and forests at sites where the species occurs is necessary.
Status 4. Species of uncertain status.
Limiting factors: Not studied. Threats include habitat destruction (old-growth forests) and removal of woody debris in recreational areas.
Status 3. Vulnerable species.
Limiting factors: Association with old-growth forest communities.
Other species of Diplocarpa or Ionomitidis.
In the photograph above, it can be noted that Mycena sp. participates in the joint colonization of the substrate. It can also be noted that some other species from the genus Ionomitidis are associated in their development with fungi from the group Pyrenomycetes.
