If interested in sphagnum bogs you can find many things simply by rinsing some sphagnum and checking the rinsate under the scope. I also like to use a moist chamber for this. All sorts of interesting things can be found in a tuft/mat of sphagnum. Rotifers, tartigrades and numerous fungal spores. Leave a tuft of moss in a moist chamber with a small amount of water at the bottom and examine the water over time. These Helicoon spores are quite distinctive.

Comments: see this species list for more observations of this fungus (or group of fungi), whose identity has evaded me for upwards of six years. in each example, the yellow stipe tissue turns deep purple in the presence of KOH. excited to not only to have a collection for sequencing and culturing, but for have received the provisional ID of Lindquistia — a xylariaceous anamorph — courtesy of IMA president, Dr. Keith Seifert, who I showed this to at the recent IMC in Puerto Rico. Dr. Seifert also possesses a portion of the collection, and I am working on gathering together more material from around the world.

this species of Helicoon is distinguished by its large conidia (easily up to 50µ long), that are barrel shaped and darkly pigmented.
I find it on a regular basis in this locality, both on leaf litter and rotten wood
Transparent crust with teeth, on decorticated deciduous wood: maple or oak. Two types of cystidia present: halocystidia smooth with bladderlike swelling at the tip and cystidioles smooth and with starlike full of crystals. There are abundant crystals, and of bigger size on the lower parts of crust; smaller ones towards the top.
Non-stromatic, unitunicate, black pyrenomycetes fungi.
Small, hard perithecia up to 0.5 mm in diameter immersed in decorticated wood, with a well-developed neck. In a mixed forest.

Long necked Coelomycetes on a relatively young, recently fallen dead Acer rubrum.
Neck about 1mm tall at most, brownish-orange, progressively paler to hyaline at the tip. Conidia produced in a partially immersed pycnidia, conidiogesis apparently annelidic or possibly phiallidic, but clearly entheroblastic.
Conidia cylindrical, sometime very slightly clavate, hyaline, smooth and aseptate measuring 18-21 - 6-7.5(8) avg 19.3 - 7.
based on conidiogenesis and conidia, I am tempted to identify this as a member of the genus Cryptosporiopsis, but I am unable to get to an exact species in verkley monograph, C. coryli is probably close, but differ in its host. However, since I am not familiar with Coelomycetes, I might be completly wrong
In sphagnum in boggy area.
Faint "mushroomy" odor.
No taste.
growing out of what I believe to be a blueberry (possibly V. cestpitosum). Final image shows comparison with one that I think was growing out of a cranberry (V. oxycoccos - the lower one)
I’m really at a loss on this one. It’s odd that the sphagnum is white. There was some whitish mycelium or something on the sphagnum, but the orange parts aren’t elevated as illustrated for Mitrula. Also, this was cup-shaped, unlike the example Mitrula. Any thoughts?

Something interesting is going at the base that looks like basidia.
On a wet ground, on a hiking path next to broadleaf forest tiny grey cup fungi. Open area and cups were growing between the grass.
Apothecia sessile, with marginal hairs, 1-2mm in diameter. Hymenium greyish, marginal hairs brown.
Asci 8-spored, operculate, IKI-, croziers(+), uniseriate.
Ascospores ellipsoid, eguttulate, uninucleate, smooth, hyaline, measured

Paraphyses hyaline, filiform, septate, without VBs, straight.
Hairs with thick brown walls, septate, without roots, with two ends (one end goes up and the other shorter pointed down) like in *Trichophaeopsis bicuspis.
on decaying piece of bark of Ulmus on the ground.
This Hyphomycetes is quite distinctive because it produce slender black with a mass of pale conidia protruding from its apex. Macroscopically. This species is very common on bark of Ulmus on the ground, but rarely numerous (This one is an exception with about 50 specimens, however most do not have a conspicuous conidial mass at their apex).
The conidiophore were not observed on this specimen as long dark setae where surrounding them. The conidia are quite fusiform with their apex hooked. The conidia are hyaline, but on some conidia the central cells are slightly dematiaceous. The mature conidia have 7-9 septa, and measure (42)45-53u X 2-3(3.5)u.
This species can confused with M. ulmicola which is also found in the region on the same habitat. However the latter produce conidia reaching 70u with up to 11-13 septa and they are more sigmoid in shape. M. ulmi is also known from other trees, in these condition it can be confused with M. boudieri which have shorter more clavate conidia. Conicomyces are probably macroscopically hardly distinguishable, but they have a long appendage at the end of their conidia.
Here is a typical M. ulmicola, note the longer conidia, with more septa and with the two ends bent (giving them a sigmoid shape)
Each "cup" embedded in the subiculum is smaller that 1mm wide. Spores are 6-7 x 4-5.5µm, apiculate, hyaline. Clamps present. Crystalline or refractive material among the hairs.
Crozier (+), Spores within range, amorphous refractive crystals present.
The fusiform paraphyses are exceeding the asci.
Alder, in alder wetland. Vouchered. Third image shows before & after hydration.
