Rotting Effects in D&D

As I re-acquaint myself with the rules of Basic/Advanced D&D, I'm remembering some of the odd bits and pieces of the game that we had to figure out for ourselves back in the day. One of these bits is the effect of "rotting" as a result of a select few monsters found in the game, most notably the mummy and the violet fungus.

5e uses a system of damage types to reconcile many of these incongruities from earlier editions, so for these monsters (and others like them), the game applies a set amount of damage and classifies it as "necrotic." In the case of mummies, the victim continues losing hit points from necrotic damage over time and can't heal until a Remove Curse spell is applied, whereas violet fungi get 1d4 attacks that do straight necrotic damage (up to 4d8 in a single round, which is nasty but not that dangerous to mid-level and higher characters), with no other lingering effect. It's a simple system that makes clear exactly what happens to the victim (one of the things 5e tends to do pretty well), but doesn't carry the same degree of threat as their AD&D counterparts.

For the AD&D versions, both creatures' rotting effects are extremely deadly at any level, but the actual physical results are not entirely clear. I started running a campaign for my tabletop group using a hybrid of the "Advanced" versions of Old School Essentials and Labyrinth Lord rulesets, but I lean heavily on AD&D to help with some of the behind-the-scenes granularity, and to adapt some of the monsters and magic items that aren't in OSE or LL.

"Why not just run AD&D?" you may ask. Ease of entry, mostly. The girls have only ever played 5e and were getting overwhelmed by the increasing complexity of the game as they leveled up, so I wanted to give them an easier set of rules to manage that still provides a fair range of flavor to play with. I also need to re-acclimate myself to the "old ways" of running the game, so it seemed like a good way to go. My plan is to ease them into AD&D as they get more familiar with how the older system works.

In any case, I dropped a single violet fungus into the dungeon I'm running, but as I read the Monster Manual entry, I found it to be fairly vague on what happens when the fungus touches someone. They get 4 attacks as a 3HD monster, and if one of their branches makes contact with a target: 

The excretion from these branches rots flesh in but one melee round unless a saving throw versus poison is made or a cure disease is used.

This immediately brings up several questions in my mind:

  1. No damage is listed, so what effect does "...rots flesh..." have?
  2. Does it matter where you are hit? AD&D doesn't have a hit location rule, so do we make one up or does the rot simply kill you outright?

  3. Obviously, if you fail the saving throw vs. Poison (also categorized as a save vs. Death), you have one round to apply a Cure Disease or the rot takes effect, but why is it not Neutralize Poison instead to match the save category (as far as I know, avoiding disease does not involve a saving throw)?

  4. It's not an issue in OSE/LL, but in AD&D, Cure Disease has a casting time of 1 turn (10 rounds). Does this mean you need to start applying it within one round (minute), but you then need 9 more rounds of uninterrupted casting to avoid the rotting effect? Neutralize Poison has a casting time of 7 segments, which seems more usable under these circumstances, but you would still need to cast it within 3 segments of the victim being touched or, presumably, the rot would kill the victim before the spell was complete (unless, again, you simply need to start casting it within 1 round to prevent the effect).

The online consensus seems to be that if a violet fungus hits you, then you will die in one round if you fail the save and have no Cure Disease spell available. That's pretty rough, especially since the text does not say explicitly that the victim dies.
