Favoritos de grey_moss

Capsules are common on this variety which is common on wood, either the base of trees or along branches. This specimen is growing on an Acacia melanoxylon trunk. Growth is slender compared to var. lacunosum which is generally on soil. Var cupressiforme is also more robust but is not recorded in central Victoria while var. filiforme is slender but lacks capsuiles and has leaves that are only straight or slightly falcate (curved). There is no costa (image 6) and on this variety the number of subquadrant (squarish) basal alar cells along the margin is around 10 or less, In this specimen the average is 8 - image 7) main leaf cells shown in the final image are long and sinuous.

This is a large form of the species and the leaf tip tapers abruptly to an acute tip that is comparitively short when compared to the other varieties. Image 7 is two leaves of H. cupressiforme var mossmanianum included here for size comparison with images 8 and 9 which cover one leaf of H. cupressiforme var lacunosum at exactly the same magnification as image 7. The single leaf at this magnification is too large to fit within one image frame. Image 10 shows the basal alar cells and a short double costa . This species is variable regarding the presence or absence of a costa and when present it is only a slight thickening of the cells. The last two images show the denticulate upper portion of the leaves.

Stomata superficial (1,2). Capsule striate (1), exostome not orange-brown (1), endostome present (4). Spores 18-36um (3). Exothecial bands ~100um wide, 2-4 cells wide (?) (4).

Although the spores are very large and the exothecial bands are quite wide I am going with L. affine based on the overall "look" of the endostome process and the lack of exothecial bands in the 100-150um range.
