Growing on base of dead Pinus torreyana.
Annual capped polypore, fleshy, pores slowly bruising brown. Cap pinkish tan, fuzzy, with upright imbrication. Pores white, angular, margins serrated. KOH-
Odor earthy like Laetiporus.

HAY-F-004363
On Rocky bar rd downslope of Slug Gulch. 2200' elevation.
Cedar and blackberry grove in the pocket of a hillside.
Odor- Negative.
Taste- Mild to bland. The mouth texture is pillowy.
KOH-Negative.
Multiple trees appear to be; partially burned, partially alive and affected by the C. spongiosa.

Oblong ascostroma with rounded to acute ends, centrally swollen; cross section 1.3 mm wide, 0.5 mm tall, with multiple parallel locules.

Ascospores 57-64 x 23-26 µm, hyaline to dark brown, starting in layer of mucous; oblong elliptical with acute ends, flattened on one side, and with longitudinal depression; distinctly the shape of a date seed. Ascospores and ascogenous tissue KOH+ green.

This appears to be a smaller version of C. umbonata that grows in a habitat different than redwood coastal forests. This was found in a montane region growing in the duff of fir, pine, sequoia and cedar during snow melt. Cap was 2.5-3.5 cm across. Stipe 5-8.5 cm long x 3-7 mm thick, cleft, hollow, rooting. Odor not distinct. Spore deposit white. Spores ellipsoid, smooth, 5-6.25 x 3.25-3.75 um. Photo of cheilocystidia in phloxine at 400x. Photo of spores in Lugol's solution at 400x.

Terrestrial under tree, possibly fruiting from buried wood debris or dead roots. Pore surface whitish (instead of the typical yellow for this taxon), but spore ornamentation is latitudinal which is diagnostic for C. flavipora. Hymenium color is perhaps variable or faded due to age.

On dead branches in drainage ravine, likely Artemisia californica. 6-7 mm thick. KOH+ black. 5 pores per mm. Hyphae yellow, 1 μm thick, KOH+ dark brown. Tramal hyphae parallel along tubes. Setae not found after searching four cross sections.
