Specimen notes
Public Note:
Lamella and pileipellis tissue dextrinoid, althought not strongly. Cap a cutis over spherical cells. Cutis ornamented with short fingers. Spore size variable, perhaps number sterigma variable. Basidia either immature basidioles or not visible, perhaps collapsed with numerous collapsed spores in mount. Seems to be one of the species where spores on the lamella are larger than those which are free. Spores length=6.4–9.4µm (µ=7.7, σ=0.74), width=3.7–5.3µm (µ=4.2, σ=0.44), Q=1.6–2.1µm (µ=1.82, σ=0.15), n=20. Without pleurocystidia. These smaller spores are closer to Horak's M. virgata from PNG, and perhaps part of a continuum. It's also possible that this indigenous fungus has spread into NZ conifer plantations - in which case M. conicola (non M. flosnivium sensu Horak) might be an earlier name. So far I have not found it in exotic plantations. If this is true M. austrofilopes then sequence data indicates Robich's M. angusta is a later synonym and the holotype of M. rebaudengo also has the same sequence but clearly a different fungus! The only consistent difference between austrofilopes and filopes is the much larger size of the cheilocystidia in this. Also see Stevenson's M. subdebilis. That described with basal disk. Desjardin shows hair-like forked caulocystdia and 4-spored (7.4-8 x 4.2-4.8) .Type of subdebilis, in my opnion, is identical to my M. 'Perseverence Rd'.
