sus_scrofa描述
tentative ID.
growing on the cut end of a wooden post, possibly Pinus strobus.
in the field, seeing that it had a shiny, silvery-green, granular crustose thallus and it was growing on old wood, i took it for Trapeliopsis flexuosa.
i now think i was wrong. the apothecia don't match those of Trapeliopsis flexuosa. my best guess at this point is a Micarea sp., which matches ecology, the thallus, and the small, marginless, white/light apothecia, such as those seen here: https://www.waysofenlichenment.net/lichens/Micarea%20prasina
Lendemer & Allen list Micarea prasina as present in NYC, along with 2 other Micarea sp.

Truffle like fungus I found on top of the dirt under a thick layer of maple leaves. Thick outer skin with geometric and circular cavities filled with a whitish semi transparent gel. Red staining around insect bites. No pronounced odor. Collected and brought home. After a few days in the fridge I cut into it again and discovered blue green tones developing from the exterior in. Spherical spores with little warts on them.

First 5 photos taken same day of collection, final 3 photos taken of rehydrated, refrigerated material approx. one week post-collection. Lower quality cell phone shot through dissecting scope eyepiece shows powerfully purple KOH rxn, which is the result of the dissolution of glandular pigments that adorn the hairs. Note curious black, appressed, pulvinate growths from which many Perrotia primordia seem to emerge. Consulted with Bjorn Wergen, who confirms that this is a known feature of the sp., especially in dry/damaged material, and particularly in populations from the US and SW Asia (Uzbekistan, Mongolia, etc.) @jackjohnsonn's observation of the same collection (https://www.inaturalist.org/observations/163424091) contains the micrographs and notes on micromorphology. same substrate as https://www.inaturalist.org/observations/163625666 - https://www.inaturalist.org/observations/163625665 - https://www.inaturalist.org/observations/163625662. ITS and micro forthcoming.
Collected during the 2023 Spring Meeting of the Pacific Northwest Key Council in Peachland, British Columbia, Canada.

found on a twig, probably Populus
conidiomata, sporodochial, erumpant, orange when dry (Picture 2), pale pinkish when fresh (Picture 4), with a darker short, stout stem. Conidiophore arising from somwhat stromatic cells of textura angularis. Conidiophore, long, often curved, hyaline, conidiogenous cells produced pleurogenously, as small strongly apically curved phialides, usually found below a conidiophore septum. Conidia, hyaline, aseptate, smooth, somewhat variable in shape and occasionally slightly sinuous, allantoid or constricted at the center. Conidia measure 5.5 - 7.5 µm x 1.8 - 2.3 µm (avg = 6.6 x 2.1).
This relatively common and distinct species here because of its coloration, large size and pleurogenous conidiogenous cells, it often grow on twigs and small branches. It also, often have a teleomorph associated with it, but it was not seen in this collection.
Nectria dematiosa is apparently similar but without a stout stem, while N. canadensis is decidedly synnematous and occur on elm.
