It is possible this tree suffered from C. huliohia, but the drastic whole death of the crown has me guessing it is this species.

Erumpant sordariomycete on Falcateria falcata. stroma up to 4.5cm across.

Pardon the redundancy of the photos - Wanted to include them all.
Campanella / Tetrapyrgos. Caps 2-8mm
UV = Faint blue if at all
On fallen twig under African tulip and Falcateria.
Size (of collection) 21cm. UV: Neg. KOH: pale brown. Notes: Greyish blue and powdery. Very small spines growing along edges, thicker white spots interspersed as well.
BDC-0000-23 Eroding at top. Pale yellow to bright yellow cap with brownish. Bright yellow toward margin. Gills pinkish to center yellow to edge. Close. Not attached. No veil remnant. Stipe no ornamentation. Maybe powder whiteness at base. Pale whitish pinkish stipe.odor mild. 4 bodies seen. Taste mild, metallic after. Odor mild delaying wood. Likely from hibiscus
Thin mazelike pores, 1-3 per mm.
KOH = Yellowish
UV = Neg.
Expanding up to 30cm across log. Thin, easily removeable from substrate.
On detached chunk of wood in Eucalyptus, Strawberry Guava, Falcateria and African tulip dominated area.
Reminds me of Xylodon from N.A.
Found by Harte singer, original observation with notes here.

Found under Ohia (M. polymorpha) in moss and near Cibotium among other native plants.
Spores a pointed rhomboid sort of shape, hyaline.
(6.3) 6.6 - 7.5 (8.1) × (4.9) 5.1 - 6.3 (6.7) µm
Q = (1.1) 1.2 - 1.3 (1.4) ; N = 15
Me = 7.1 × 5.8 µm ; Qe = 1.2
Basidia with relatively pronounced slightly in-turned sterigmata.
41.8 - 60.8 (61.6) × (5.6) 5.8 - 9.2 (11.9) µm
N = 10
clamps infrequent but present. Forgot to measure the widths of the generative hyphae, but can do so if this is ever a candidate for description.
Size: 2cm. KOH: lime/yellow. Notes: No apothecia, fibrils emerging from lobe edges.
Size: 4cm across. 1-3mm lobes. KOH: Neg. Notes: No apothecia, subtle pruina on lobes, marginal paler lobules(?) Possibly a Pannaria sp.
Waxy tuberculate crust on Ohia - M. polymorpha. Spreading up to 30cm, in well decayed and damp wood, found when flipping a chunk of wood.
On Dicranopteris linearis. Taste slowly becoming somewhat bitter.
Tenative ID. On one of the following trees - Ohia, Koa, Strawberry guava.
Short spines around 1mm long clustered, a somewhat gelatinous feel to them. Fruitbody too small for KOH test.
