Old dead limb in rain-shelter under Pinus contorta
| | GEN | | calicioid lichen, on old rain-sheltered dead conifer limb |
| | THAL | | lt green scattered tiny areoles |
| | APO | | stalk v thin wiry dk brown, cup not abruptly expanded lt brown w prom whitish pruina on most, mazaedium black but looking lt brown due to pruina, mazaedium K+gold (but can't find POL+ crystals) |
| | SPORE | | 1 celled, round but often misshapen, brown, areolate-cracked, 4.6+/-0.4um (n=14) |
Oh, hell, that's supposed to be a "brown" mazaedium, not black. Within which Trevor's key fools me into the wrong species, as well, since I called my spores clearly platy-cracked, at very least definitely textured. I was 100% convinced this was
Calicium viride, but it just shouldn't have white pruina (if any).
Description of Calicium viride from Nordic Lichen Flora Vol. 1, 1999.: (Admittedly no longer very appropriate for this observation! But here it is anyway...)
| | GEN | | on bark and wood of Picea in old coniferous forests, on lignum of Pinus sylvestris, on Betula, Quercus, and Alnus, throughout cool to temperate areas in north and south hemispheres |
| | THAL | | superficial, granular to minutely verrucose, intensely green, rarely immersed, K-, C-, KC-, PD- |
| | APO | | ascomata with a brown pruina (K+r) on the lower side on the capitulum or epruinose, 1.1-2.2mm high, all parts I-(water mount), capitulum lenticular, 0.4-0.7mm diam, excipulum dk brown, consisting of isodiametric to sl elongated heavily sclerotized anticlinally arranged cells, outer surface of excipulum often covered by a smooth to strongly irreg later of brownish amorphous crystals, hypo blackish brown w convex upper surface, stalk black 0.1-0.2mm wide sometimes w a brown pruina in the upperpart and a greyish pruina in the lower part, central part of stalk consists of d intertwined and mainly periclinally to irreg arranged 2-3um thick hyphae, outermost part of stalk slightly paler and often with an I-gelatinous coat, asci clavate 20-25x4-5um w biseriately arranged spores |
| | SPORE | | ellipsoidal, 12-14x6-7um, semi-mature spores w an ornamentation of spirally-arranged ridges, mature spores constricted at the septum and the ornamentation is irreg cracked-areolate |
Notes: a very variable species, particularly w resp to ascoma size and shape, the occurrence of the brown pruina and thallus thickness. Characterized by the green, superficial thallus, the K+r brown pruina on the lower side of the capitulum, and very irreg ornamentation of the spores. Similar to
C. salicinum if thallus immersed, but differ in spore size and ornamentation, and in having clavate (instead of cylindrical) asci.












Mycobilimbia carneoalbida [] [voucher]
| | GEN | | crust lichen, on moss at base of cottonwood or aspen |
| | THAL | | v thin pale stain making moss look diseased but not otherwise noticable |
| | APO | | tiny pale creamy disks, v convex, no noticable rim, dull, no pruina, tough to section (thick gel?), epi and hymen and hypo all hyal, para br'd a bit near tips but uncolored, asci clavate, I+ blue tip perhaps with narrow axial mass penetrating fully |
| | SPORE | | 8 per ascus, (0)1-3 septate, hyal, sl golden in I, smooth, fusiform to oblong, septae quite thick in K, apparently roughened at some stage of immaturity but often clearing to smooth and featureless in K/IKI (13)15+/-1.3(18)x(4.3)5.1+/-0.52(6.3)um (Q=(2.4)3.0+/-0.32(3.5)) (N=13) |





purple wart fungus []
| | GEN | | fungus, on old aspen 1" limb on ground |
| | THAL | | vivid wine-red warts protruding through bark when fresh, drying grayish dull pink-purple-brown color, structure is sort of leafy almost after it emerges, collapses when dry, powdery, distinct darker skin and white interior below hymenium, soft gelatinous when when wet |
| | FR | | basia, 2 spores per basidium, cystidia long and tapered on both ends and totally immersed in hymen 100x10um or so, all tissues K- |
| | SPORE | | 12x7um or so, thick rough perispore, ellip, hyal |
No idea.
