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. Helicoon pleuriseptatum Beverwijk from Sphagnum washes Oct and Nov 2021 Lake Verde bog and Black Ck (small patch of Sphagnum near slow rivulet).
Conidia 40-60µm diax20-30µm height, flattened, 6-10 coils/spirals, dark brown.
Mycoportal includes 22 specimens from the UK, US, NZ and Russia (Siberia). Most from bog habitats.
On Abies twig.Triradiate conidia, arms up to 100u long, multiseptate, brown on a single conidiophore, probably blastic, the colony is scattered among two discos - a) Mollisia-like with light coloured hymenium, b) dark hymenium, clavate spores (tear drop) 17-23x3-5u, spores may eventually become 2-3 septate, hyaline; a small colony of Septonema? sp also present (conidia 2-septate, 15-18x6-7u), middle cell larger and darker than end cells.

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.
Probably on Fraxinus pennsylvanica (Green Ash).
Asci 8-spored, unitunicate, IKI+b, uniseriate.

(9.7) 10.3 - 11.5 (12.2) × (4.3) 4.7 - 5.4 (5.5) µm
Q = 2 - 2.3 (2.5) ; N = 20
Me = 10.9 × 5 µm ; Qe = 2.2
Collected by Dr. Steven Stephenson, University of Arkansas
On the previous year's grasses. Perithecia about 1mm in height producing long needle-shaped spores.
Melanospora arenaria L.Fisch. & Mont.
Habitat: lignicolous? (no other fungi evident in sample); large colony on underside of well-rotted conifer wood, wet subalpine forest (1800 m).
Ascomata: 1.0 - 1.1 mm total length; emerging from tufts of white mycelium at base, topped with a crown of hyaline setae that are arched to form a ‘cage’ joined at the top in a globular mass. Ascomata neck 800 - 900 µm long x 90 - 110 µm wide, composed of interwoven hyphae, yellowish-orange to pale brown, central cavity filled with spores. Setae 200-300 um long.
Spores: (11.7)12.4-13.8(14.7) x (9.6)9.9-11.2(11.9) µm; hyaline to dark brown, ellipsoidal, smooth-walled with a terminal germ pore at each end.
collected on rotten decorticated wood probably of Acer saccharum, in old mature forest
Description : Colonies on substrate effuse, greyish irregular, patches up to several mm in length (Picture 1).
Conidiophore arising from a slightly larger basal cell, erect, rarely branched, dematiaceous, except for apical cell (or occasionally cells), which tend to be much paler and slightly clavate, Lower part of conidiophore conspicuously ornamented with dark, flat, warts (Picture 6). Conidiophore up to 250µm in length and 3.2µm in width, very fragile (Picture 2-5).
Conidiongenous cells produced laterally, or much more rarely, at the apex of the conidiophore, Conidiogenous cells are dematiacous slightly bent and generally unbranched. Conidiogenesis from a single hyaline cup/bowl shaped collarette at the tip of conidiogenous cells (Picture 7-9) . Multiple conidia produced from a single collarette, the conidia agglutinate together into a sticky whitish mass
Conidia are hyaline asymetrical, somewhat bent or falcate, they are smooth and at least some have 1 septum at maturity. (Picture 10 - 11). conidia measure 10 - 13 x 1.5 - 2.5 µm. Conidia lack sheets and setulae (appendages)
Using the key in Seifert et al Genera of Hyphomycetes, I arrive to the genus Dictyochaetopsis, a genus that is not accepted by everyone. amongst the species in the genus D. glauconigra match this collection rather well, a description of D. glauconigra (as Menispora glauco-nigrum) is provided by Hughes in Kendrick in their review of the genus Menispora in 1963. The most notable difference is that the conidia or this collection might be slightly wider, and the conidiophore a bit shorter, but a good measurement of the latter was difficult due to their fragility. The only other species that I know that have the unusual ornamented conidiophore is the very similar D. apicalis (the type species of the genus), which differ mainly by its longer, 2-3 septate conidia.

SPECIES NAME: Moellerodiscus advenulus (Phillips) Dumont
COLLECTIONS DATA: AC 2417, 2487. Auburn woodlot June 2020, 2021
SPECIES DESCRIPTION: ascomata translucent with orange-yellow to green "sphaerocysts/cells" on the stipe; asci blue in Lugols; spores 7-9x2-4um with gel appendages
NOTES: Seems to be widespread on Larix sp needles in June in the litter beneath trees. An excellent description is presented by Fallah & Shearer (2001) and the Freshwater Ascomycetes website. Some excellent photos are found on ASCO-SONNEBERG website as Calycina/Antinoa spores a bit larger and no apparent appendages. There is a R.F. Cain collection (Phialea advenula) near Norwich Ontario on Larix needles RF 2761 annotated by KP Dumont in the NYBG on Mycoportal. I assume the rest of the material is in TRTC. The best generic name for the species is not clear. The latest treatment discusses its placement in Lambertella (Zhao et al. 2016).
