tyson_ehlers's Identifications

@tyson_ehlers @pamjanszen @ryan_durand Thought this was some weird scenario where a Lamproderma sporotheca was seated on top of an immature Licea variabilis, but then I stumbled upon the page in Poulain on this species and it blew my mind. Super cool. The gelatinous stalk thingy disappeared after a day.

Plasmodiocarps - Growing on wood.

Peridium - Light brown, granular.

Capillitium - Dark brown, wavy, with occasional nodes and occasional branching. Appearing ridged.

Spores - ~10um, grouped, non-reticulate.

Sporocarps - 1-2mm tall, growing on wood in old growth forest.

Stem - Black, lightening to brown near base. Usually ≈ ⅓ of total sporocarp height.

Peridial Net - Nodes variable, flat, made of orange granules.

Cup - ⅓ - >¼ of total sporotheca height, with granule-filled longitudinal lines.

Spores - Yellow in mass. ≈6um, minutely warted.

@tyson_ehlers @ryan_durand @pamjanszen Ran through Poulain, got to C. vulgaris. I couldn't spot any transverse wrinkles, but at the same time Poulain makes it seem like that's not really necessary for the ID. I know Cribraria are tricky, so generally here I'm being hesitant. Thanks.

Stalk - ≈1mm, vibrant wine red, sometimes splitting into 2, filled with cysts.

Calyculus - ≈0.5mm deep funnel, lighter wine red than stalk, inner surface covered with papillae connected by ridges, edge torn.

Capillitium - Red, elastic, attached loosely to calyculus, seemingly primarily but not exclusively at the base. Ornamented with partial rings, full rings and some warts. ≈3-4.5um in diameter (without ornamentation).

Spores - ≈6um, ornamentation not visible at 400x (as far as I went).

@pamjanszen @ryan_durand @tyson_ehlers Narrowed it down to either A. affinis or A. helvetica. Thinking A. affinis is a better fit for quite a few reasons, but I'm still uncertain. Thanks.

Same collection site as: https://inaturalist.ca/observations/190848841

Spores dark, irregular spines, 9.9-12.0um.

Capillitium flat, expansion at joins, large free ends.

Stalk about 1/4 total height. Sporocarp <3mm tall, poor condition.

@tyson_ehlers @ryan_durand @pamjanszen What do I need to do to ID this one? Given H. decipiens was T. decipiens in the Poulain book, I'm not sure those keys would really work. I just realized that characteristics I thought distinct to H. decipiens are shared by other Hemitrichia, so I'm not sure where to go from here. Thanks.
